      COMPLIANCE
      Under AS 5062- 2006, the ETI fire suppression system is a Fully Engineered
Foam System, where designers are trained to perform risk assessment procedures, and
then undertake design procedures which include, sizing the system in regard to foam
quantities required, hydraulic systems, with nozzle quantities and pipe sizing. This
makes ETI stand out among other systems on the market, which only qualify as Pre-
Engineered Fire Systems under the standard.

       The ETI system is a foam water mix, which is designed as a local application
system. As such it provides higher levels of cooling, and is suitable for un-enclosed or
enclosed spaces; where fires occur, as a result of surfaces being coated in combustible
materials. It is also tested for indirect application and can provide protection in
associated areas such as, where fuel spills have accumulated under equipment, where
fires have recently occurred.

      The ETI system has been tested accordingly, after consultation with the National
Association of Testing Authorities NATA (Australia). NATA referred ETI to the
Indonesian Government Accreditation Authority “K.A.N.” This body meets international
standards, and its acreditations are recognised by NATA, and other standards
accreditation bodies world wide. See NATA Mutual Recognition Agreement (MRA).
http://www.nata.asn.au/

       This resulted in a special Inspection Services Body (ISB) being established that
could meet the requirements to perform the evaluations and listing functions in this
specialised field, to international standards. This body has now been established over
three and a half years, and has been successfully audited to international standards.
The audit team assigned has also included an NFPA expert to ensure the compliances
in regard to those NFPA standards invoked.

The listing process will be always ongoing because ETI is an innovative company
always committed to further development of its product. For listing information;

TRAINING

       Competent designers trained and accredited by ETI or its Agents, are obliged to
comply with this manual and pay due diligence to AS 5062 – 2006 when designing a
fire protection system.


This fifth edition has been released as the ETI, listed product, to Australian Standard
AS 5062 - 2006. The ETI system has changed very little from its previous version,
indicating the high degree of system performance that was already evident in the ETI
system. In fact there were no fundamental changes needed to the basic fire fighting
characteristics of the system.


       Heavy mobile and stationary machinery represent substantial investment. Loss
of this equipment, subsequent production and danger to the associated personnel is
ever-present. Whilst mining is perhaps the major application for the ETI fire system,
there are a multitude of other applications including, forestry, construction, power
generation and marine equipment, operating in harsh environments inside, outside,
underground and at sea.


      The installation of a fire detection and suppression system is essential to
minimise the risk to both operator and equipment, and is a mandatory requirement in
many of the states of Australia. With many modern vehicle or equipment designs, the
operators are often positioned well away from the location of the fire risk. Modern cabs
are well insulated from noise and temperature, and operators may not be aware of the
presence of fire in their equipment, until it is beyond the control of normal portable fire
extinguishers. Faced with these dangers, operators can, and do panic, and in most
cases, abandon the equipment, rather than undertake first aid fire protection.




      Field experience has shown the need for improvement over earlier Dry Chemical
Powder suppression systems. These systems generally suffered from compaction of the
powder, and often resulted in less than efficient operation. The advantage of Fire
Fighting Foam Systems over gaseous, dry chemical powder and vaporizing liquid
systems is their ability to control fire after the discharge is complete, to cool hot spots
preventing re-ignition and to flow with the fuel spills underneath the vehicle.

      ETI is the leader in the development of foam protection systems, having one of
the most experienced people in the business at its helm. These types of systems have
been installed on hundreds of vehicles, and other equipment over the past 20 years,
and have proved themselves as successful fire detection and suppression systems.
Following on ETI’s commitment to continual improvement, we have now adopted and
further refined this system, based on years of field experience. The ETI system has
brought to the market, the increased performances that the changing market
demands. At the time of writing, the ETI system has been developed and used in
markets in Australia, PNG, Indonesia, South East Asia and Africa; where world leading
performance is demanded. It was designed to exceed the performance of the best on
current market.




     The ETI Dual Actuation Fully Engineered Foam System has been designed to
add benefits like:
Choice and ability to mix rise of pressure (ROP) and loss of pressure (LOP)
detection and actuation systems. No other company can offer this unique
advantage!




Reinforced, extra strong brackets, with the smallest possible space demand and ease of
installation and maintenance.




     All of these features put the ETI Fully Engineered Foam Water Spray System
ahead; and further, it has been designed to allow various levels of protection, from fully
automatic detection and suppression systems, full engine shut down and cabin
monitoring, to simple suppression only systems, with manual actuation. Customers
can decide for themselves, what level of protection, they wish to install on their
equipment, to meet their local regulations.

FIFTEEN LITRE MODEL

The fifteen litre model was introduced for light equipment system (LES) designs. It
allows the designer to fit smaller systems to smaller machines where space is limited
such as four wheel drive vehicles. It is supplied in a stainless steel only for light
weight.

STAINLESS STEEL CYLINDER RANGE 1 ½” PORTED.
The use of stainless steel cylinders is often preferred for light weight and limted
corrosion resistence. The cylinder has a thinner wall than steel cylinders, but no real
allowance for corrosion loss. AS 5062 mandates the use of potable water. The ETI foam
used has an anti corrosive effect when added to potable water, thereby reducing the
likelyhood of corrosion issues.

This model uses the ETI dual actuation D model valve with Burst Disk as shown.

STAINLESS STEEL CYLINDER RANGE 1 ¼” PORTED.
This model was introduced with similar properties to the 1 ½” stainless steel range.
The cylinders being 1 ¼” are more in common with standard types used in Australia. A
key change however is the use of a new model Type II dual actuation valve. This
features side discharge port. The loss of pressure port is also side mounted and
enlarged to ½” BSP to allow fitment of an optional LOP manual actuator. No burst disk
is used in this model. The filler plug has a new 20 bar spring loaded relief fitted.

This model uses the ETI dual actuation Mk III model valve without Burst Disk.

                           SAFETY RELIEF DEVICES

Safety relief devices are mandatory to AS 5062 and must comply to the standards
invoked. It is the designers and installers responsibility to ensure that the approved
relief device is correctly installed.

NOTES
  1) Mk I system released in 2006 used an ROP valve only see(.....) listed in valves.
     This used a spring loaded releif mounted in a separate ½” BSP port on the
     cylinder. Contact ETI for spare part information.

   2) The MKII system or “D” valve system uses burst disks mounted in the valve. See
      following chapter for technical information.

   3) The MK III system using 1 ¼” BSP ported cylinders and the Mk III valve uses the
      releif valve mounted in the filler plug. See below




PHOTOS ABOVE – Shows 1 ¼” Filler plug with relief valve in filler plug. Second photo
shows with plastic protective cap fitted over. This arrangement is used in 1 ¼” S.S.
cylinders where Mk III valve is used without burst disk relief. Note also groove in
thread, as safety pressure vent if operator attempts to open while under pressure.

CHAPTER 2             CYLINDER VALVE ASSEMBLIES



      ETI still offers its original and highly regarded Mk I ROP valve for rise of pressure
applications. In addition two Dual Actuation valves have been listed. The D model or
Mk II, the 15mm (1/2”) version for light vehicle applications using the 15 litre cylinder
and the new Mk III model with horizontal discharge port and optional LOP manual
valve actuator.




      The ETI DUAL ACTUATION cylinder valve is a MARKET LEADING DESIGN, IN
WHICH ETI HAVE A PATENT APPLICATION PENDING! It is supplied in a 20mm ported
design for most applications and a 12mm smaller version for the light weight 15 litre
foam cylinder. It is of tough stainless steel construction and is designed to be reliable
in the harshest of environments.




It is unique in that it is a genuine Rise of Pressure (ROP) valve and a Loss of Pressure
(LOP) valve together. This means that it is capable of using both actuation and
detection devices together. While other systems are designed to use, one or the other,
the ETI Dual Actuation system genuinely gives the customer flexibility. It is easy to
change devices later if needed, and it is possible to use both types of actuation and
detection devices together to give the best possible mix of detection and actuation
choices.

VALVE - MANUAL ACTUATORS


BURST DISK MANUAL VALVE ACTUATOR FOR D OR Mk II VALVE


An optional manual actuator may be mounted on the dual actuation
valves. For 1 ½” ported cylinders with the D model valve, it is positioned
in place of the Burst Disk Assembly plug but maintains the burst disk
membrane. This actuator works by rupturing the burst disk membrane
and causing a loss of pressure actuation. If this actuator is fitted and
operated, then the burst disk membrane must be replaced to service the
valve back to operational condition.

Note: The15mm model is used on the 15 litre LES cylinder using the
smaller ½” valve. The 20mm model is used on all 1 ½” ported cylinders
using the dual actuation “D” model valve.



A vent plug is supplied as standard with each valve assembly. This is only
used when not using the ROP port. This prevents a vacuum lock for LOP
actuation. Likewise if the ROP port is connected with ROP actuation
piping



THE VENT PLUG IS REMOVED AND REPLACED WITH A CHECKVALVE.

THIS CHECKVALVE MUST BE FITTED TO THE VALVE at the ROP port!

 PART# CHECKVALVE



 This is not supplied with the valve assembly and must be ordered
separately if any form of ROP actuation is to be used



                                  BURST DISK


A burst disk is fitted, calibrated to rupture before the test pressure is
reached in the cylinder. That is 25 – 28 Bar. this is to protect operators
against over pressure accidents. If the burst disk ruptures, this will cause
the valve to “Loss of Pressure” self-actuate and discharge all contents.

           PICK UP HOSE ASSEMBLY

      Valve assemblies use a flexible pick up hose, to allow the cylinders to be
mounted either vertically or horizontally. Siphon tubes are constructed from a
composite of brass, electrometric hose and stainless steel. The table below indicates
the correct part of each cylinder assembly.

CHAPTER 3                  CYLINDER BRACKETS
        ETI cylinder brackets are manufactured from welded carbon steel and painted
black or red. They are of advanced design, by being integrated with cylinders to
minimize space usage. The base plate is designed to be no wider than the cylinder
itself.


       Vibration eliminators are also available and are recommended in applications
where the cylinder assemblies are subject to continuous movement or vibration. The
optional weld mount provides a very convenient method of fixing brackets. Vibration
eliminators complete with weld mounts are attached to the bracket. The bracket is
positioned and the mounts tack welded in place. Remove the bracket and fully weld the
mount with a 3mm fillet weld.


      Straps have easy tension adjustment using the adjustment bolts; the straps
have rubber strips to prevent abrasion.

CHAPTER 4                FIRE FIGHTING FOAM


      ETI uses high grade aqueous film forming foam. This agent is critical to
performance. There are many different AFFF foams on the market, and these are
known generally by the acronym AFFF. There are many brands available, although
they rarely appear in these types of engineered fire systems. We advise extreme caution
in this area. Any foam that does not comply with ETI design standards may
render the system ineffective.


       What is very important to understand, is that while many standards invoke
AFFF application rates, all the standards fail to pin down the fire fighting performance
of the agent itself. Because foams can aerate, similar to detergents, it is possible to find
a range of fire fighting foams on the market that range in performance from excellent;
to suitable only for washing dishes!


       ETI’s technical director Leigh Waldon has had many years experience in foam
fire suppression systems, he has used his knowledge of live fire testing together with
actual field and customer feedback, to select the highest and most effective grade
possible. ETI foam is a 6% AFFF Foam Concentrate and is mixed on site during
testing, commissioning and servicing. It exhibits vapor suppressing properties on
flammable hydrocarbons liquids. The use of this agent ensures that fire knockdown
performance is maximized; with rapid foam cover and extinction. It also protects the
inside of the cylinder against corrosion.


      The flow on effect also has the ability to provide vapor sealing over spills. The
fuels leaked during a fire behave as liquids under gravity. The AFFF solution does
likewise, and its ability to flow over fuels and suppress them, is another feature that
makes this foam so effective.




      Because the AFFF solution is 94% water, it exhibits a cooling effect that for
practical purposes is the same as water. This is a critical factor in stabilizing the
suppression performance. It is a known fact that many highly developed fires have
superheated material in the fire risk. Some agents manage to extinguish the fire, only
to experience re-ignition, because combustible material is still above auto-ignition
temperature of the fuels still present.

       The nozzle arrangement is the business end of the system, delivering the AFFF
foam, over the risk area, during a fire. The designer must ensure the whole risk is
covered, using the spray performance described herein. The design section, calculates
the foam application rate, and discharge time. Selection and quality of nozzles are
critical to a balanced design.

NOZZLE DETAILS

The nozzle cap is marked with the orrifice size in mm followed by the spray angle in
degrees. For Example 2.5 60 indicates a 2.5mm orifice x 60 degree angle.

The Cap is permananently attatched to the nozzle with a strong stainless steel cable
lanyard. The nozzle is threaded ¼” BSP T male thread and uses an Oring to create
resistance for the cap to stay in position, yet blow off when discharge occurrs. Use
petroleum jelly for lubricant when assemblying, or after cleaning when servicing.




Note: The nozzle performance is based on a maximum protection area of 0.75 square
meters. The nozzles nominally spray circular or eliptical patterns, when spraying at an
angle to the target. Overlaps of spray pattern are normal practice when laying out a
practical installation. These overlaps give higher concentration of foam. It is good
practice to set up overlaps in high heat source areas, such as turbo chargers, so that
the cooling effect can be maximised.

Refer to the design section for system calculations to achieve listed design
performance for application rate.

Whilst the 2.6mm orifice is the standard orifice used for design calculations, described
in this manual, the ETI system may vary nozzle orifice, to change application rate
performance in special circumstances. In these instances, the ETI design department
must verify the designs to supply and use non standard orifice nozzles.

SAE100R1TypeAT, and the performance requirements of EN8531SN. For minor
installations of 8 nozzles or less; hose that meets or exceeds SAE 100R6 may be used.
To comply with AS5062, hoses must meet flame Resistance Designation U.S.MSHA
schedule 2G.

The discharge pressure of the ETI system commences at the storage pressure of 13.7
Bar.
This discharge pipework system will always be somewhat less than this pressure and
the safe working pressures of the hoses described above far exceed these requirements
by their relevant standards.


                               STAINLESS STEEL TUBE




Stainless steel tube is supplied for areas where intense fire exposure may be
experienced. It also very useful in temperature environments, such as enclosures over
engines, where heat causes deterioration of the polymers used in the hoses. The risk
here also is that as the discharge hoses are not normally under pressure; they fail to
give prior warning of failure. Stainless steel tube in the 12.7mm size is intended for
these areas, and for all practical purposes has an indefinite working life for high
temperature and fire exposure.
       Stainless steel tube is rigid and can be formed into bends using a tube bending
tool to not less than a radius of 50mm. It is cut with a tube cutting tool and flared to
SAE 37º (JIC) using a flaring tool and backed up with a sleeve and nut. The tube is
12.7mm outside diameter x 0.8mm wall thickness, annealed seamless type 304 or 316
stainless steel tubing.

HYDRAULIC FITTINGS
      A range of hydraulic hose fittings may be used, provided the sizes match the
hydraulic design and they are in compliance with; Hose SAE100RT. Fittings should be
described as JIC.

CLAMPING NOZZLE ARRANGEMENTS TWO PART CLAMPS
      Nozzle alignment is critical to reliable performance. Nozzle arrangements must
keep their alignment to ensure proper AFFF foam distribution. Failures can result from
loose hoses allowing rubbing against structures where vibration exists, causing failure
during discharge.
      Stainless steel tube and hose, in proximity to nozzles is to be clamped using the
two part fire rated ceramic clamps. These clamp together in two halves, and all sizes
use M-6 Cap screws. The base is plated steel and can be welded into position. The fillet
weld each end, should be a minimum of 2.5mm x 20mm long.
      In each nozzle location, a two part fire rated ceramic clamp, must be in position
on each side of the nozzle; one clamp must not be more than 300mm distant from the
nozzle, and the other not more than 500mm distant. For hose connection, one clamp,
not more 150mm, and the other not more than 500mm. When hose and tube meet at a
nozzle assembly, the minimum distances for clamping for both types must be used.


                     TWO PART FIRE RATED CERAMIC CLAMP




       Under this listing ETI design rules require that the following ceramic clamps are
used in all areas that are part of the defined fire risk areas. Plastic clamps are not
permitted as they are not suitable to exposure to fire. The two part clamp may be used
for clamping 12 mm stainless tube where nozzles are mounted. For clamping stainless
steel tubing, use CLAMP12ST which has a rubber bush to allow effective clamping of
the tube without fracturing the clamps.

       The 6 mm model is designed for clamping sensor tube where LOP automatic
detection is designed.


CLAMP12, CLAMP20 and CLAMP25 are also suitable for clamping loose hoses for
SAE 100R1AT in 6mm, 12mm and 20mm nominal bore sizes.

MAIN TEE INSTALLATION
For proper hydraulic flow, it is customary to carry the foam, from the foam cylinder in
a larger hose, and then tee down to a smaller size to carry foam to the nozzle
assemblies.
FOAM CYLINDER TO MAIN TEE. From cylinders 21 litre to 85 liter, a 20mm hose is
normally used or a 12 mm hose can be used if nozzle total is below 12 for the 11 litre
cylinder a 12mm or 10mm hose can be used.
ON THE MAIN TEE for cylinders 21 litres to 85 litres the hydraulic design for nozzle
feed from the main tee is 12mm nominal to a maximum of 14 nozzles in any one
direction. For cylinder 11 litres, the hydraulic design for nozzle feed from the main tee
is 6mm nominal to a maximum of 3 nozzles in any one direction.
To facilitate this design requirement, the following main tees allow for easy
management of the relevant foam line sizes. The main tee may be mounted in its own
independent bracket if inline clamping nearby is inadequate. The larger tee may be
ordered with or without mounting bracket. The Light Equipment System (LES) tee
comes standard with mounting bracket.


NOZZLE CLAMPS (larger systems using 12mm lines after main tee)
ETI provides an alternate option for clamping nozzles. The Nozzle Clamps below
provide a sturdy U-Bolt clamp which fixes the nozzle system directly. It is available in
two styles which are straight or ninety degree brackets. Brackets have pre-drilled holes
for bolting or may be welded in place.


For Nozzle bracket assembly 90 degree type = part – NOZBKTAA.
For Nozzle bracket assembly straight type   = part – NOZBKTMT.

”P” Clamps


       Where loose hose needs to be held neatly in place and where no excess force is
likely to be applied ”P” clamps may be used. These are versatile and many machines
have a multitude of existing fasteners in place that may be used in situ, to effect a neat
and effective installation. Tapped mounts are also provided, where no existing fixing
can be found. These are easily welded into place.

Zip Ties


       Zip ties may be appropriate, for example, where a harness of existing machine
hoses, already runs. The designer/installer may elect to simply tie a hose run in with
this arrangement. The installer must take care that the routing and clamping is
professional. In any case no hose should run unclamped, for more than a length of
1200mm.NOTE: Hydraulic hose, two part clamps, P clamps and zip ties are to be
supplied by the agent during installation; in compliance to this document. These do
not form part of the scope of supply from ETI.

       CHAPTER 6 - DETECTION & AUTOMATIC ACTUATION

                      RISE OF PRESSURE (ROP) SENSORS

       The ETI AFFF system is actuated when using ROP automatically when the
 detector/sensor is exposed to elevated heat and achieves a sustained 175-200 degrees
 Celsius. The ETI Fire Sensors are very versatile and robust with an extremely low false
 alarm performance. In fact, false alarm outside installation errors is as yet unknown.
 The sensor operates the main foam systems and notifies the alarm system. These are
 provided in a range of lengths from .40cm to 2 metres.

        The sensor is installed with a filter. When used, or at scheduled service intervals,
 the whole sensor tube must be replaced. There is no practical limit to the quantity of
 sensors used; however it is an ETI requirement, that two sensors be used as a
 minimum, in the primary risk area to provide failsafe by double redundancy.
 Inspection simply requires the opening of the filter assembly. Evidence of black carbon
 material, indicates that the sensor has fired and now must be replaced. The inner core
 of the tube should not be removed.

       Experience has shown that these sensors may be placed at least 250mm from
 hot exhaust components and at least 350mm from turbochargers.

      A check valve must be used at the actuation manifold to prevent back flow on
the Fire Sensors. Fire Sensors may be bent to suit the shape of the environment using
a tube bender to a radius of not less than 100mm and not more than 45 degrees per
bend.
LOSS OF PRESSURE (LOP) SENSORS
       Loss of pressure sensors are simply made of thermoplastic tube 6mm in
diameter. This sensor tube is connected to a rise of pressure circuit and is strategically
positioned above areas identified in the risk assessment as fire risks requiring fire
detection. The sensor tube is pressurised from the ETI dual actuation valve and
therefore is pressurised to the same pressure as the foam cylinder, i.e. 13.7 Bar. This
tube is tested to be stable at this pressure to environmental temperatures of 100
degrees Celsius. When this tube is exposed to fire, the rapid elevation in temperature
causes the material to plasticise and the internal pressure causes a rupture. The
sudden release of pressure on the actuation circuit causes the ETI valve to open and
the alarm pressure switch will notify the fire alarm. The ETI dual detection valve also
has a pressure equalizing capacity which will compensate small leaks in the detection
system without system actuation. This will result in a slow reduction in cylinder
pressure over time and will require service correction of the leak fault.

          CHAPTER 7                 REMOTE MANUAL ACTUATION

     ETI MANUAL CO2 ACTUATOR FOR RISE OF PRESSURE (ROP) ACTUATION
       The ETI Rise of Pressure (ROP) Manual Remote Actuator is a multipurpose
actuator of a higher capacity than commonly used, and can be fitted to any part of the
machine being protected, within substantial distance limits. The head components are
made of brass, and the back plate and cover are made of carbon steel, and coated in
Signal Red paint. In mobile machines it is common to have one mounted adjacent to
the operator’s seated position, and in places where an emergency exit may take place.
Therefore, two or three units are common but up to six can be used on larger
machines.
       It comes two models and the configuration allows for surface mounting,
assembled on its back plate. For concealed mounting, remove the head assembly and
drill the surface selected, (3mm to 6mm thick) to suit, and fit using the nut assembly
on top.
       The instruction label must be placed on the front of the cover, when surface
mounted. In the case of concealed mounting, the instruction label must be placed
visibly, not more than 75mm from the strike knob. The connecting pipe work shall be
¼” (6mm) flexible hose only; complying with SAE 100RI. It shall be supported at the
designer’s discretion using two part ”P” clamps and zip ties as required, at distances
not exceeding 600mm. Any areas exposed to mechanical damage by vibration, rubbing
or sharp edges must be protected by appropriate materials, including spiral protectors,
made from a robust plastic, such as polypropylene. In cases where the hose may run
through an area considered to be in the fire risk, an outer hose sheath of a rubber
textile type shall protect it; using reinforced hose of a minimum combined wall
thickness of 3mm.
      The allowable length of connecting pipe work, between the ETI Manual Remote
Actuator, and the Cylinder Valve, must not exceed 30m. The maximum number of
foam cylinders that a single manual remote actuator can be connected to is 6. A check
valve must be fitted at the actuation manifold site for each actuator connection.

Cylinder Specifications:
Complies to AS 2469 2005/AS 2470 1998
CO2 Cylinder Life : 5 Years-refer to date on cylinder
CO2 Charge           : 150g net
Cylinder Material : Cold Rolled Carbon Steel


      The ETI actuator cylinder uses a frangible seal. After use the cylinder and ’O’
ring must be discarded and replaced. During servicing the cylinder must be weighed to
confirm gross mass to that stamped on cylinder. The age of the cylinder, must be
checked for date compliance at installation and servicing.

                        REMOTE MANUAL ACTUATION – LOP


       The ETI Loss of Pressure (LOP) actuator is a multipurpose actuator that can be
fitted to any part of the machine being protected, within substantial distance limits.
The head components are made of brass, and the back plate and cover are made of
carbon steel, and coated in Signal Red paint. In mobile machines it is common to have
one mounted adjacent to the operator’s seated position, and in places where
emergency exits may take place. Therefore, two or three units are common but up to
six can be used on larger machines.




      The ETI LOP actuator comes in three models. The first two are compact models
where one is fitted with a pressure indicator and one is not. If the model with the
pressure indicator is fitted in the driver’s location, it gives a simple visual check
capability of the current pressure in the detection circuit and foam cylinder. The third
model is a larger model featuring a liquid filled pressure indicator.

ACTUATION MANIFOLD AND PIPEWORK - RISE OF PRESSURE
      For ROP, The ETI actuation manifold function is to co-ordinate pressure changes
from any actuation device, such as a sensor, or a remote manual actuator. It then
transmits that change, directly to the foam discharge valve. It does this by virtue of
check valves at all points of entry from the actuating devices for ROP systems. Each
checkvalve is aligned to direct an actuation pulse into the manifold. The checkvalve
then prevents that pulse being directed down the line of any other actuation device. In
this way, the system is failsafe protected against a pressure pulse being lost to another
actuation line which may be faulty. It also has the effect of maintaining the maximum
possible pressure in the actuation circuit by not directing the pulse, unnecessarily
down the line of any other actuation device. ETI checkvalves are male threaded; the
outlet end ¼” BSP to screw into the manifold and the inlet end is 7/16” JIC to receive
hoses assemblies from any actuation device. This also eliminates the potential for
incorrect installation.
       The Actuation Manifold also has a pressure switch fitted; when an alarm panel is
installed, it will notify the alarm panel instantly any actuation device is initiated. The
manifold is made of solid brass and comes with a mounting plate assembly.

For LOP a simple manifold is supplied that allows the installation of alarm pressure
switch and the low pressure warning switch. It also acts as a tee junction connecting
the actuation line to the valve and the actuation circuit for manual and automatic
actuation.

Note:
The above manifold parts include a bolt on the mounting plate for easy fitting by
welding.

SPECIAL NOTE

The ETI system is a reactive system for ROP and requires two sensors in critical risks.
The principle here is double redundancy. Since each detector is not supervised, the
use of two independent detectors provides the double redundancy principle to protect
against failure. Perhaps the best known example of this is two pilots in a commercial
aero plane both capable of independently flying it.

Remote actuators must be also independently connected to the manifold through
checkvalves for the same independent capability.

The ETI LOP system is a pro-active system that is designed to fail to safe. This means
that if a detection circuit is breached anywhere, it will tend to actuate the system
immediately rather than fail to actuate it later. When using the low pressure
monitoring option, it is also supervised. As such it does not require independent
actuation systems. The sensor tube and remote actuators may be connected
independently to the manifold or may be connected by tees with each other.



PIPEWORK - FLEXIBLE HOSES

For the actuation system, ETI specifies hose that meets or exceeds the requirements of
SAE100R1 Type AT and performance requirements of EN8531SN. For minor
installations of 8 nozzles or less, hose that meets or exceeds SAE 100R6 may be used.
To comply with AS5062, hoses must meet flame Resistance Designation U.S.MSHA
schedule 2G. Size 6mm or ¼” is used only for the actuation system.

CHAPTER 8            FIRE ALARM AND ENGINE SHUTDOWN




OVERVIEW
ETI has listed in these design rules a “System Status Indication Panel” hereinafter
referred to as an “Alarm Panel”. Its function is to provide an audible and visual alert to
the operator in the event that the system is actuated. It has other important controls
such as fault monitoring, system discharge reporting, and engine shutdown controls.

Engine shutdown is vital to allow the “foam water spray system” to work effectively. It
is acceptable to make this a driver responsibility in the event of fire. However,
experience has shown that in many such emergencies, manual procedures are not
reliable. ETI therefore recommends using automatic engine shutdown, from the Fire
Alarm Panel. Many customers and operators have concerns for machine operating
safety in this event. Braking and steering systems for example, which are powered by
the engine, need consideration when designing engine shutdown, to allow the machine
to be brought safely to a halt. For this reason, the ETI Fire System has a 6, 12 or 24
second delay to engine shutdown. This allows an agreed delay period to be
programmed, so that upon alarm, the driver has time to manually stop the machine
and shut it down. In this way, the alarm panel backs up the operator, if he panics and
runs. (As normally is the case!)
       Two sets of voltage free contacts are provided. One set operates from open to
closed circuit, on the fire alarm. The other set operates from closed circuit to open
circuit, on the fire alarm. It is the responsibility of the customer to interface this switch

                         ETI FIRE SYSTEMS TECHNICAL MANUAL   5th EDITION
                                                                                   Page 54 of 131

to the relevant engine management system. Normally, the customer will delegate this
responsibility to internal maintenance or to the machine supplier.


In some cases, the customer may elect not to have a fire alarm, because the engine (or
other fire risk) may be obvious to the operator. In this instance, engine shutdown can
still be connected by direct wiring the notification switch, to the engine management
system. However this method will not allow for delayed engine shutdown.


The shutdown Alarm Panel, is a robust and compact unit, and will operate on an
external power supply of 12V DC or 24V DC. The panel will monitor the status of the
pressure switches fitted, in the system and provide audible and visual alarm functions,
(cylinder low pressure and fire alarm). Upon detection of a fire, the Alarm Panel will
commence the automatic engine shutdown sequence, (if connected). An adjustable
timer is provided in the panel, and can be set at 6, 12 or 24 seconds.


ETI Fire Systems P/L recommends that the connection to an engine shutdown device
should only be carried out after consultation with both the operators and
manufactures of the equipment being protected.


DESCRIPTION

The System Status Indicating Panel (Alarm Panel) is designed to Australian Standard
AS 5062. It is a robust and compact unit operating from an external power supply of
12v Dc or 24v Dc.

The Panel will monitor and sense a FIRE ALARM condition and commence an
automatic engine shutdown sequence as well as audible and visual status displays.
The engine shutdown sequence may be delayed but not aborted by the operator.

When the engine shutdown sequence is complete, it may be overridden by the a service
technician, by using a screw driver to undo the lid of the panel and pressing the
Engine Shutdown Override switch which is located inside the panel.

The panel will also monitor and sense a CYLINDER LOW PRESSURE condition which
will be displayed as a SYSTEM FAULT and also a SYSTEM DISCHARGE condition
which will be displayed as SYSTEM DISCHARGE.

The panel may be reset by a service technician after the fire alarm, system fault and
system discharge conditions have been rectified, by using a screw driver to remove the
face of the panel and pressing the reset switch which is located inside the panel.

OPERATION
The System Status Indicating Panel monitors pressure switches, which are in a closed
circuit condition in normal circumstances. If the system detects fire or is manually
actuated, the alarm switch becomes ‘open circuit’ to notify the fire alarm function. A
pressure switch also monitors the foam storage system and becomes ‘open circuit’
when pressure drops below 9 bar. This notifies the fault function on the alarm.

ON: The GREEN ‘ON’ LED is continuously illuminated when the panel is powered
from a 12 or 24 volt dc supply. The panel will reset on ‘power-up’ and in this ON state
the panel is monitoring the status of all inputs. The only operator function on the
panel is a red button which will operate the TEST function and can be used during a
fire alarm to delay engine shutdown.

When the optional Battery Backup unit is wired to the Panel, the GREEN ‘ON’ LED is
continuously illuminated whilst powered from a 12 or 24 volt dc supply. Upon loss of
the DC supply, the unit will revert automatically to battery backup and the GREEN
‘ON’ LED will commence flashing intermittently once every three seconds indicating
that the Panel is now operating on battery backup. The backup battery will provide a
minimum of 72 hours of standby backup power. When the battery reaches a low volts
condition, the Panel’s SYSTEM’S FAULT alarm will be activated indicating to the
operator that total loss of power is imminent.

FIRE ALARM When the fire alarm pressure switch detects actuation the contacts will
open activating the panel’s latching RED ‘FIRE ALARM’ LED and a continuous
audible buzzer will be heard and commence an engine shutdown sequence with a time
delay of six, twelve or twenty-one seconds as selected by the timing jumper. Also, the
optional external alarm relay will latch, activating external alarm devices.

Engine Shutdown CANNOT be aborted but may be DELAYED by pressing the RED
‘DELAY ENGINE SHUTDOWN’ switch either momentarily or holding down as required.
The selected delay period re-commences upon release of the switch.

 Approximately three seconds prior to engine shutdown, the continuous audible alarm
indicator will change to a rapid intermittent signal to alert the operator that the
shutdown delay period has almost expired. The delay switch is also functional during
the rapid alarm period.

 At the completion of the engine shutdown delay period the panel’s engine shutdown
relay will activate and the RED ‘ENGINE SHUTDOWN’ LED will illuminate. The audible
indication will now change to a post alarm indication which consists of an intermittent
signal. A one second audible signal occurs once every fifteen seconds.
This audible signal may be muted by using the red switch. A momentary push of the
switch will mute the buzzer and illuminate the AMBER ‘MUTED’ LED. Each
momentary push of the switch will toggle the mute on or off. This will now be the only
function that the switch will have.

Should the vehicle require to be moved, the engine shutdown may be overridden using
the internal OVERRIDE ENGINE SHUTDOWN SWITCH. Undo the panel’s lid and press
the internal Override Engine Shutdown Switch. The engine shutdown relays will de
energise and the AMBER ENGINE SHUTDOWN LED will turn off. Engine Shutdown
cannot be re-activated until the panel has been RESET.

Once the FIRE ALARM condition has been rectified the panel may be reset by pressing
the internal RESET switch. Use a screw driver to undo the Panel lid and press the
RESET switch. Once the Panel has been reset ensure that the lid is secured in place.

SYSTEM FAULT: This alarm condition will result from either of the two following
conditions:-
1. Upon loss of cylinder pressure (as set by the pressure switch) the cylinder low
pressure switch contacts will open activating the panel AMBER ‘SYSTEM FAULT’ LED
and intermittent audible indication. The SYSTEM FAULT condition will not activate the
engine shutdown sequence or the optional external alarm relay. The audible indication
may be muted during this alarm condition.
2. Low battery condition when operating from the optional battery backup unit. In this
condition, the panel green ‘ON’ LED would also have an intermittent flash indication.
When the backup battery reaches a pre-set low volts level the Panel AMBER ‘SYSTEM
FAULT’ LED and intermittent audible indication will be activated. The SYSTEM FAULT
condition will not activate the engine shutdown sequence or the optional external
alarm relay. The audible indicator may be muted during this alarm condition.

Once the SYSTEM FAULT alarm condition has been rectified the panel may be reset by
pressing the internal RESET switch as per FIRE ALARM section on page 5.

SYSTEM DISCHARGE This alarm condition will result from either of the two
following conditions and is selectable by setting the slide SW3 which is located inside
the panel to either position A, or position B. No system discharge pressure switch is
connected to cable wires BLUE and GREEN when position A is selected. When position
B is selected, a system discharge pressure switch MUST be connected to cable wires
BLUE and GREEN.

1. STANDARD CONFIGURATION - SW3 set to position A, and no pressure switch
connected to cable wires BLUE and GREEN. Upon detection of a fire alarm the RED
‘FIRE ALARM’ LED will illuminate together with continuous audible buzzing. If the
system does actuate and discharge this will be followed by detection of a cylinder low
pressure condition which will quickly drop through 9 Bar as the system is discharging.
When these two conditions occur together the panel interprets that the system is
discharging and the discharge LED is illuminated.

2. OPTIONAL CONFIGURATION
SW3 set to position B and a system discharge pressure switch connected to cable wires
BLUE and GREEN. For customers who want this configuration, an additional alarm

This switch must be installed to sense discharge pressure within one meter of the
valve. Upon discharge the pressure switch physically senses actual discharge and will
open circuit above one bar. This will illuminate the discharge LED.


TEST
The panel may be tested by pressing and holding the RED TEST SWITCH for
approximately five seconds until the alarms activate. Release switch when test
commences. During test, the FIRE ALARM, SYSTEM DISCHARGE, SYSTEM FAULT
AND SYSTEM ISOLATED LED will all be illuminated together with a continuous
audible indication. The test will also commence the engine shutdown time delay
period at the end of which the engine shutdown relay will energise and the ENGINE
SHUTDOWN LED will illuminate. Also the optional external alarm relay if fitted, will
energise and activate external alarm devices.

During the test, the engine shutdown may be delayed (Refer to FIRE ALARM section on
page 5) and the selected delay period verified. The test is complete when the audible
indication changes to post alarm. The panel may now be reset by momentarily pressing
the RED test switch. Only the green ‘ON’ LED should now be illuminated.


IMPORTANT NOTE
Reset by this switch is allowable during testing only. If the alarm has actually been
operated other than by test, it will require internal resetting being accessed using a
Phillips screwdriver.


MUTE
Whenever there is an intermittent audible alarm (post alarm), the RED MUTE SWITCH
will mute the audible buzzer and illuminate the AMBER ‘MUTED’ LED. The mute may
be toggled on or off by momentarily pressing the mute switch.


ENGINE SHUTDOWN DELAY
Selectable time delay settings of 6 seconds, 12 seconds or 24 seconds are located
behind the enclosure lid. Unscrew the panel lid and move the labeled SET DELAY link
to the required setting and ensure that the lid is re-fitted and sealed properly. Also, in
compliance with AS 5062 after receiving a fire alarm the shutdown function will latch
to prevent re-start of the machine untill the fire system is serviced. A trained
technician only must remove the face of the alarm and internally reset using the reset
button.

INSTALLATION

MOUNTING PANEL
Remove the panel front cover and unplug the three connectors which are wired to the
multi-core cable. Set aside the front assembly to a protected location until the housing
has been mounted. Mount the housing in a suitable location utilizing the two outer
mounting holes.

SETTINGS
Set the engine shutdown delay timing to the customer requirement by moving the SET
DELAY link to one of three delay options (6, 12 or 21 seconds). The link will be factory
pre-set to 6 seconds. Set the slide switch SW3 to either position A or B as required
(Refer to Operation section SYSTEM DISCHARGE on page 6).

Reconnect the front cover assembly ensuring that the three connectors J1, J2 and J3
are properly located and seated. Screw down the lid ensuring that the seal is properly
seated.


IMPORTANT

 The alarm must be connected to a powered circuit that allows a minimum of 72 hours
stand by current at the above stated specifications. This curcuit must not be able to be
terminated by the operator. This is because the alarm panel latches the shutdown
circuit after receiving a ‘fire alarm’. This is to prevent the operator re-starting the
machine and causing a repeat fire with the fire system now out of comission. If the
operator can isolate power to the panel it will re-set the shut down and the alarm panel
function will not be in compliance to AS 5062.

Wire the panel multi-core cable to the vehicle system using either a 12 pin IP67 rated
Deutsch connector or other termination method which meets the required cable
termination specifications. The connector pins to the Deutsch connector should be
crimped using the correct crimping tool, part number 35-466.

If the Panel housing is mounted directly onto, and making contact with, the vehicle
earth, the multi-core cable screen may be left un-terminated. However, if the housing
is mounted onto an insulated or plastic surface, the multi-core cable screen should be
terminated and screwed to the vehicle’s chassis.


Wire the Panel’s DC supply directly to the vehicle’s battery and fit a 5 Amp fuse to the
positive lead as close as possible to the battery terminal. Use a waterproof in-line fuse
holder.

                 AUXILLIARY ELECTRICAL EQUIPMENT


Operators of equipment often use auxiliary equipment that is required to interface with
the fire equipment. These may include data logging or telemetry devices that allow
immediate reporting of a fire event into those systems. Some larger machines require
external sounders and beacons to also be added and possibly specialised fire
protection in the form of optical fire detection *


Because the ETI system is an engineered system, these devices may also be simply
engineered and interfaced as needed. Engineering shall be in compliance to the
appropriate standards, and acceptable to the authority having jurisdiction.

The approved interface is achieved by using an additional alarm switch,
Part APALASSY2BAR              This provides two sets of voltage free contacts present in
normally open and normally closed conditions. This will provide a simple connection
solution for virtually all applications where such an interface is required. See wiring
diagram above.

   CHAPTER 9                  DESIGN PROCEDURE 1
                               RISK ASSESSMENT

The design of any fire system first requires an understanding of exactly what the fire
risks are prior to designing the system that will deal with an unwanted fire event. Risk
management is a mandatory process required for compliance to AS5062–2006 and ETI
design rules. ETI Workplace Risk Assessment control process (WRAC) is a listed and
compliant process for this requirement and is the listed and approved process in
conjunction with our design process. When the risk assessment process has
determined the need for fire protection of a foam water spray type, then the ETI design
procedures aided by the approved design program can bring about an effective fully
integrated design within the risk assessment process.
The ETI process requires the client to appoint a committee responsible to manage risk.
This committee should bring to the table all the expertise and experience that allows it
to identify the hazards and risks, rate them on scale, and agree on control measures to
achieve the required result. The software program will generate the records of the
design, the risk assessment and technical specifications to form a comprehensive
design record that is compliant to AS5062-2006.


                 THE ETI FOAM SYSTEM IS AN ENGINEERED SYSTEM


The ETI product is a fully engineered fire system that requires the designer to do
calculations, select foam quantities, nozzles and pipe sizes. The approved design
program software guides the designer through the processes by a step by step path
and undertakes the calculations and checks selections for compliance in critical areas.


This allows the designer to produce a comprehensive design and a detailed cost
estimate in very short order.

NOTE

The reality of the market place is that customers often speculate the need for a fire
system and ask for a preliminary budget or quote. ETI has allowed for this by having
the program record in these instances, that the risk assessment is not yet done and
therefore the design cannot yet comply. AS 5062 requires that a risk assessment is
done before design. In these instances, the approved ETI procedure is that when the
risk assessment is done, the system design is also re-done. It is therefore
recommended that ETI agents should declare any quotes prior to risk assessment as
preliminary to that process being done. An experienced designer will likely predict an
accurate specification with little or no variations later. However the risk assessment
often reveals factors not known to the designer in the early stages.

                     RISK ASSESSMENT PROCEDURE



Risk assessment is to be carried out by the supplier before installation this must be
carried out by the approved ETI agent or representative. (Refer AS 5062 Section 2,
2.1.2.1.).



This process must include the Owner, the operator, maintenance personnel, the
manufacturer’s representative, the supplier, Hirer, insurer and specialist fire
consultant (refer AS 5062 Section 2, 2.2.).



ETI has listed the following forms as part of its design procedure and AS 5062-2006
compliance program. They are designed to guide the designer through a compliance
process by ETI design rules and AS 5062-2006. To comply with ETI design rules a copy
of AS 5062-2006 must be used with reference to Section 2, Fire Risk Management, and
Section 3, Fire Risk Reduction.



Risk management follows a logical thought process that leads the assessment
committee to make decisions on whether risks are acceptable or not. Figure 2.1 in
chapter 2 of AS 5062 shows this process in the form of a flow chart which does not
allow the process to stop until the risk becomes acceptable.



Fire Risk Reduction is the process that makes risks acceptable. This has many facets
including control measures such as Design, Safeguards, Administrative Controls, Fire
Protection Equipment, Site and Public Facilities. ETI’s main contribution is to supply a
leading fire suppression system that comes under the heading of Fire Protection
Equipment. We must remember however, that this is only a link in the chain and that
this process is helping the customer manage a whole range of factors that affect fire
risks.

                               WRAC OUTLINE

ETI has adopted the Workplace Risk Assessment Control procedure as the
approved and listed procedure for designing ETI foam water spray fire protection
systems. It is the listed procedure for designing this system. If a customer uses
another competent system, compliant to AS5062, it may be used at their
preference. The designer simply then transposes the data from that assessment
into the ETI design records and makes the appropriate notation.


WRAC is a simple system that looks at each risk in isolation. It breaks risk into two
key components, PROBABILITY and CONSEQUENCE. When these two factors are
substantial then we will have a risk. When consequence is negligible then
probabilities will not likely matter as the outcome will be acceptable.
An example of this might be applied to a car that has frequent electrical failures,
because the car already has a control measure in the form of a circuit breaker, the
consequence is reduced to negligible as this prevents over current failures that
might lead to a fire. Inversely a good example at the other end is the risk of being
hit with a lightning bolt when strolling down the street. Most people would agree
that the consequence of this happening would likely be death, and so rate it as
CATASTROPHIC.
Yet most of us take this risk every day without giving it a thought. This is because
we have already assessed this risk sometime in our life as an improbable event that
makes the whole risk acceptable. The point to be made to ETI designers is that
there is no such thing as the elimination of risk!
Many people travelling in commercial aircraft today, when stepping through the
doorway into the cabin, would love to get a guarantee that the aircraft will not
crash. No such guarantee is possible!


However it is refreshing to know that commercial aircraft have some of the most
comprehensive risk control measures in place that make the risk acceptable to
most of us and in fact safer than driving motor vehicles as an alternative.




To quantify each risk assessment in the ETI process, the following chart must be
referred to. In each case a choice is made on Probability and Consequence to
achieve an outcome. It is the responsibility of the risk assessment committee
chairman to consider the input from the team members and to make a final
decision, reflecting the consensus of the team. Debate will often occur and it is wise
therefore in these cases to select the conservative choice.

SURVEY THE RISK AND MEASURE THE SURFACE AREA OF THE RISK
The physical survey of the machine to be protected should follow the fire risk
assessment, used for the other areas of risk to be protected.
During the survey, consensus should be achieved with the client on such
considerations as cylinder size, quantity and location, remote actuator locations, alarm
panel location and engine shutdown requirements. Separate risk areas can be
calculated separately. If these are covered by a single system then the results can be
added together to form a total.

In an engine environment, measure the general length width and height measurements

CALCULATE THE QUANTITY OF NOZZLES NEEDED

With the area to be protected known, the designer must now determine the number of
nozzles needed. Chapter 10 points out that the listed performance of the ETI nozzle
NOZCAPBR has a listed maximum area of protection of 0.78 square meters. Therefore
to be slightly under the maximum ETI adopts 0.75 square meters as the effective
design factor for this nozzle.
Therefore:


                        A
              N=
                        E

    WHERE; N = NO OF NOZZLES - MINIMUM
           E = LISTED NOZZLE AREA CAPACITY – SQUARE METERS
              (For NOZCAPBR E = 0.75)


NOTE The minimum number of nozzles in any design shall be no less than four (4).


 DETERMINE THE MINIMUM DISCHARGE TIME ALLOWED

Designs of 50 seconds plus discharge time are recommended, however where space
limitations prevent selecting foam quantities to achieve this minimums shown below
may be used if there is no indirect foam application required.

ETI recommends the application of as much foam as is practical in design. Designs
should avoid being close to minimum, in an effort to maintain the highest practical
safety factor.

INDIRECT APPLICATION
The risk assessment and design process may identify areas where leaking fuels are not
naturally drained, and become captive under the engine or equipment. These may
typically be under engine sumps, bilges in marine vessels, or the risk assessment may
have identified the risk of under vehicle fires from fuel spills. In these cases a
measurement or estimate allowance must be made of this surface area. This surface
area must also be added to the design calculation, for extra foam quantity needed.
Because the foam flows on to the bilge or sump, this extra area does not need to be
considered for nozzle quantity, unless the designer assesses that it needs a direct
nozzle application. Where allowance for indirect application has been included the
discharge time shall not be less than 50 seconds. This is based upon ETI testing to AS
5062 Appendix E Test E4 test 2.

                  DIRECT APPLICATION ONLY
ETI recommends 50 seconds as a normal minimum discharge time. However in this
case the discharge time is based upon ETI testing to AS 5062-2006 Appendix E Test
E4 test 1. It has been shown that fire extinguishing times on direct application are very
fast. Delays in engine shutdown however can reduce effectiveness and so increased
discharge time needs to be added to allow for this. Therefore, discharge time to be
added shall be a minimum of 20 seconds, plus the discharge time designed for
automatic shutdown. ETI design selections for this are 6, 12 or 24 seconds. Where
automatic engine shutdown is not fitted, the minimum discharge time shall be 50
seconds.

   •   The ETI design program only passes 50 second minimum discharge time
       designs. Where shorter discharge times are to be used from the above chart,
       consultation with ETI technical department is recommended.

          CALCULATE THE MINIMUM QUANTITY OF FOAM REQUIRED

The ETI fire protection system is listed on a performance using an application rate of
4.1 liters per square meter per minute. This is an accepted application rate used in
NFPA 11 for hydrocarbon fuels. To achieve this application rate and the selected
minimum discharge time, an amount of pre-mixed foam must now be calculated as
follows.

QUICK SELECTION CHART
For convenience, the chart below quickly correlates the required performance
relationships between the number of nozzles quantity of foam and discharge time.
To calculate the minimum foam required and the minimum nozzles required the
following chart provides an easy selection matrix to choose from standard foam
cylinders and nozzle quantities and will then provide estimated discharge times. Note
that it is color coded. Green is the normal performance range that provides foam
quantities and discharge times that are regarded as giving a performance in fire
fighting that would result in a low risk of failure. For higher risk protection more
conservative selections may be made in the blue range to reduce risk even further to
very low risk. The yellow range may still provide effective fire suppression albeit with
less than preferred quantities of foam. Applications where space prohibits the provision
of larger storage cylinders are candidates for this range. It must be understood that the
risk is higher as the discharge time is shorter. Nevertheless it may be prudent to apply
a fire system of this type rather than none at all. Tests in the full size ETI fire simulator
have consistently shown strong performances in discharge times of less than 20
seconds, hence the yellow range is designated to as low as 25 seconds.

                         PIPEWORK CALCULATIONS



The following calculations must be done to check pipe sizes for the discharge system.
For each section of pipe work the following design calculation must be done.

MINIMUM INTERNAL DIAMETER FOR FOAM PIPEWORK IN MILLIMETRES



   D=                O^2 X N

      Where; O = NOZZLE ORIFICE DIAMETER IN mm
                 (For NOZCAPBR = 2.5mm)
             N = NO OF NOZZLES.



Notes FOR PIPEWORK Internal Diameter

 The designer must calculate the minimum pipe internal diameter for each section of
pipe. F is the total number of nozzles being supplied in each section of pipe. The
designer may average the number of nozzles to take into account multiple cylinders
being used and splits after tees.


The minimum Internal Diameter shall be regarded as the minimum orifice opening
through any fitting or section of pipe work. For hydraulic hoses, hose tail fittings
typically provide restrictions in the form orifices that are less than the nominal bore of
the hose. For simplification, the Internal Diameter of an hydraulic hose with internal
hose tails must be regarded as being effective to not more than 80% of the nominal
Internal Diameter of the hose. For example, a 19mm hydraulic hose will be regarded as
having an Internal Diameter of 15.2 in regard to the above calculation.


In any design, foam discharge pipe work shall not be less than 6mm nominal Internal
Diameter.

The maximum pipe length shall be determined so that when the following calculations
are done for the selected pipes, the total for V shall not exceed the system design
allowance for foam in litres.



                             X D ^2 X L             V = VOL OF FOAM MINIMUM (LTRS)

Notes for Maximum pipe length


1) The designer must do this calculation for each pipe size and total length used. For
Example V1 may be the calculation for the primary supply line and V2 may be the
calculation for the supplementary line forming a ring main and branches in a lesser
diameter. The results of each calculation are added and this must not exceed the foam
supply in litres.

 6.2) MAXIMUM ACTUATOR PIPE LENGTHS
The actuation system is designed to be piped using 6mm nominal bore hose as
described earlier. For rise of pressure sensors, the following design rules apply.

   I)         MAXIMUM PIPEWORK LENGTH. The maximum pipework run of 6mm or ¼”
              hose as measured from the sensor by the shortest path to the foam valve
              shall not exceed six times the sensor nominal length.
   II)        MINIMUM PIPEWORK LENGTH. The minimum pipework run of 6mm or ¼”
              hose as measured from the sensor by the shortest path to the foam valve
              shall not be less than two times the sensor nominal length.

 AS 5062-2006 REQUIRES a general arrangement of drawings showing the layout of
the system and detailing the location of major equipment. This is the responsibility of
the agent’s designer and installations team. The design program does provide
assistance with this.



SYSTEM SCHEMATICS

The ETI FOAM WATER SPRAY SYSTEM may be configured in many schematic layouts.
General actuation devices are formed into Rise of Pressure type (ROP) and Loss of
Pressure Type (LOP). The ETI system has a Patent Pending covering its unique ability
to handle both types of device independently or concurrently. When both types of
actuation device are used together, we refer to it as a dual actuation type.

Our training package uses a practical model to demonstrate the system. However the
following schematics may assist the designer to understand the principles.

           CYLINDER INSTALLATION & OPERATING GRADIENTS

 Cylinder assemblies are normally installed vertically. Because of the flexible pick up
hose the cylinder assembly is rated to be rotated a full 90 degrees and still work
acceptably. This is the only part of the system that has any consideration to gradient.
For vertical mounts the 90 degree limitation will in almost all cases overcome any
concern about gradients. The cylinder assemblies may be also installed horizontally. In
this instance the cylinder is rated to 90 degrees rotation where the valve is raised
above the horizontal axis. The system is limited to 10 degrees rotation whereby the
valve is below the horizontal axis. For horizontal mounting, the designer will need to
take this into account. It may be advisable to mount the cylinder with the valve end
partially raised to improve performance against the gradient limitation.

NOZZLE LAYOUT

 The layout for installation needs to ensure good coverage of the top, sides and ends of
the risk, which is usually a diesel engine block. The nozzles must be positioned in
accordance with their listed performances stated in this manual. The ETI system is
designed to deliver a nominal 4.1 litres per minute per square meter for a minimum
using the approved nozzle.


DISCHARGE TIME MINIMUM
The minimum design discharge time is normally 50 seconds. This takes into
consideration, high extinguishing performance in both direct and indirect application.
Some installations do not allow enough foam storage to achieve this ideal minimum. If
there is valid reasons to accept lower discharge times this may be acceptable when
properly considered by risk assessment. See chapter 10 for design rules for discharge
times less than 50 seconds.



MAXIMUM DISCHARGE TIME
This is calculated so that the foam used, is applied within 20% of a rate of 4.1 litres
per minute per square meter of the protected area.


TESTING DISCHARGE TIME
The theoretical discharge times do vary substantially in practice because of the many
pipework and cylinder configurations that designers and installers may use. There is a
substantial safety factor in the design allowances, however actual performance needs
to be nominally in line with the theoretical design. Practical test results must be within
20% of the calculated design to be deemed a pass.

POSITIONING SENSORS

Rise of Pressure (ROP) automatic actuation will happen by using ETI fire sensors. They
are comprised of a 12mm stainless steel tube as described previously. They may be
bent to a minimum bend radius of 100mm to fit the shape of the environment. The
detector is mounted using 12mm two part ETI Ceramic Clamps, at spacing not
exceeding 500mm. Of important note here, is that ETI requires the use of two of these
sensors in critical areas. This is because the integrity of the actuation line is not
monitored by any device to confirm if it is in working order. Obviously good practices in
fitting and checking during servicing provide a high reliability factor. By having two
sensors however, ETI uses a risk control procedure called, double redundancy. This is
a proven technique for many critical functions. The idea of this is that, either sensor
can actuate the fire system. The probability of one failing is remote. The probability of
both failing is so remote that it may be considered negligible.

These sensors contain a propellant core, and when they reach a critical temperature,
between 175 and 230 degrees Celsius, the propellant will automatically ignite. The
resultant combustion sends a pressure pulse through the actuation system. The check
valve manifold directs that pulse directly to the cylinder valve to immediately release
the foam discharge. At the same time, a pressure switch mounted on the manifold,
trips and notifies the alarm panel. This in turn alerts the operator if he has not already
observed it. These sensors are safe to handle and do not easily actuate. They are stable
in engine environments and are approved to be stable up to 130 degrees centigrade.
They can be positioned as close as 200 mm to exhaust systems without any problem.

The sensors are designed to meet a very demanding requirement, where they must
remain stable in a very tough environment, such as over the top of an engine, which is
hot, dusty and oily with constant noise and vibration. They must reliably detect fire
without false alarm. These sensors do this because they are robust. In this
environment they are not sensitive. The detection time cannot be quantified as there
are so many variables. Essentially they react when exposed to direct flame. Close to
the engine is good because this also pre-heats them to ambient temperature and
reduces the time for the inner core to heat up in the event of fire. In our simulator they
are exposed to fire from cold, this adds further to reaction time. It is good practice to
position them where the risk assessment has determined that fire will most likely
occur and that they are in the most likely position to receive direct flame.

Loss of Pressure (LOP) sensor tubing is positioned similarly over the identified fire risk.
This tube is designed to handle ambient temperatures up to 90 degrees Celsius at the
charge pressure of 13.7 Bar. As such care must be taken to not position it too close to
exhaust systems, including turbo chargers. A simple pyrometer can be used on
existing machines to establish temperatures in the fire risk, in normal working
conditions. This will need to be assessed for high engine work rates and high ambient
temperatures.

REMOTE MANUAL ACTUATION

Remote manual actuators must be positioned with emergency response
considerations. It is vital that one be positioned adjacent to the driver or operator
allowing that person to manually actuate the system immediately he is aware of a
fire. It is recommended that another actuator be positioned at the emergency exit
point at ground level. This provides the driver a second opportunity to manually
actuate the system when evacuating; and also allows any nearby personnel to
actuate from outside the driver’s position of the machine. Larger machines may
have more than one emergency exit, and it is these that usually require more than
two remote actuators. The carbon dioxide energy released on actuation is very
strong. For ROP a normal maximum 6mm pipe work length is 12 meters from
actuator to cylinder valve measured by the pipe route. Up to six foam cylinders may
be initiated from one C02 actuator.

For Rise of Pressure installations, hose complying with SAE 100R1AT having an
internal diameter of 6mm is used. Please refer to the schematic layout below, which
shows the layout of this arrangement. Note the manifold is using check valves at
each input device connection. These perform two functions, firstly they keep the
actuation pulse maximised by not allowing the pressure pulse to be sent wrongly
down the lines to other actuation devices. Secondly, they protect against an
actuation pulse leaking or to fail, in the event that one of those other lines had a
leak fault.

If any hose is run in the fire risk area, where it may be exposed to substantial fire, it
must be sheathed with a textile braided rubber hose of 12mm nominal bore.

For Loss of Pressure actuation, the same specification hose must be used.
Pushlok hose is also approved if preferred.


TEMPERATURE LIMITATIONS

The ETI system is designed to a maximum ambient temperature of fifty degrees
Celsius (50 deg C) and a minimum of zero degrees Celsius (0 deg C), as measured
by the local meteorological authority for the area of operation. Where an approved
anti freeze is used in the foam mix, the minimum temperature may be reduced to -
15 degrees Celsius (-15 deg C). The fire risk area may be exposed to temperatures
up to one hundred degrees Celsius (100 deg C) and even up to one hundred and
thirty degrees (130 deg c) for short periods.

CHAPTER 13               INSTALLATION REQUIREMENTS

The following guidelines are intended to assist. They presume that the installer is
already trained and accredited by ETI and is competent to undertake the task. These
notes therefore form an outline of the tasks the trained installer must undertake.
Distribution systems are a combination of flexible hose and rigid stainless steel tube.
Flexible hose is utilized for its ease of installation and resistance to vibration.
Conversely rigid tube is fitted in areas prone to mechanical damage and exposure to
extreme temperatures and fire.


DISCHARGE SYSTEM - Nozzle/Flexible Hose/Stainless Steel/Tubing
The nozzles are to be mounted in a manner to prevent them from being moved once
fixed in the desired position.
Nozzles are to be placed in a position that allows the application of the foam solution to
target high risk areas such as Fuel Injector Pumps, Oil Pumps, Fuel and Oil Filters,
and Turbochargers. Distribution of foam should be delivered over the entire identified
risk.
Stainless steel tubing may be installed in fire risk areas. Flexible hoses may be used in
these areas, but reduced life may result.
Support the distribution of hoses and tubing securely with the mounted hose and tube
using ETI Ceramic fire rated clamps. Clamps are to be positioned at the recommended
spacing intervals as detailed in section ‘Discharge Systems’ and at each side of any
radius section and between each nozzle location. Any bolts and welding used to secure
the clamps to the equipment must be in accordance with the customers or
manufacturers specifications.
In areas where abrasion is considered a significant risk hose protection spiral guards
must be used in critical abrasive areas.

CYLINDERS
Secure the cylinder bracket to the equipment, insert and clamp the cylinder with the
pressure gauge to the front. Vertical mounting is the preferred orientation. The flexible
pick up hose allows horizontal mounting, although some reduction in total discharge
may be experienced. If horizontal mounting is required in a vehicle, ensure that the
extinguisher is positioned along the length of the vehicle so that its valve is positioned
towards the front or rear of the vehicle. Ensure there is sufficient space available for
the connection of hoses without kinking, and that the connections do not place undue
stress on either the valve or the pipe work.
Ensure the instruction label on the cylinder is easily visible. If not an extra cylinder
label can be located next to the cylinder in a position where it can be easily read in the
event of fire.

                                                                                Page 95 of 131
      JANUARY 2009              COPYRIGHT STRICTLY RESERVED
Ensure that the fixture the cylinder bracket is secured to, is capable of carrying the
load of the cylinder, and can handle the additional vibration that will be applied. Refer
to the customer or manufacture of the equipment for the most suitable location for
mounting the cylinder(s). Special supports for holding the cylinder bracket or
reinforcement supports may be required for some installations of the cylinder(s).
Any bolts and welding used to secure the cylinder to the equipment must be in
accordance with the customers or the equipment manufactures specifications.

SENSORS AND ACTUATORS
For Rise of Pressure actuation, the sensor core is able to withstand a temperature of
125ºC for a minimum period of 6 months but care must be taken not to locate the
sensors in close proximity to Turbo Chargers and Exhaust systems.
Locate the sensors above and or around the hazard. The distance away from the
surfaces of the hazard must be sufficient to reduce the ambient temperature felt by the
sensor to 125ºC or less for Rise of Pressure and 90 degrees or less for Loss of Pressure.
Support the sensor every 400mm with securely mounted ETI Ceramic fire rated
clamps.

Bending Rise of Pressure sensors is not preferable, however if it becomes necessary the
minimum bend radius is 100mm.
For Rise of Pressure the maximum allowable extension of the pressure circuit from the
sensor to the main cylinder device is 6 times of the length of the sensor and the
minimum allowable extension of the pressure circuit from the sensor to the main
cylinder device is two times that of the sensor. The minimum length must be not less
than two times the length of the sensor.

When fitting remote manual actuators, it is recommended and is often mandatory in
some places, that one of the manual actuators be located in the operator cabin and at
least one at ground level, at an exit point.
When selecting the location of manual actuators, consideration should be given to the
fact that they must be accessible, yet not prone to possible mechanical damage and a
buildup of dirt which could hinder the operation of the manual station.

Actuation lines from each sensor and each ETI Remote Manual Actuator are to be
connected to the manifold block fitted with check valves. The manifold block is to be
mounted outside any fire risk area.
Actuation lines that are located in a fire risk area may be sheathed with a rubber outer
hose of minimum 3mm wall thickness if any area of the line is considered to be
exposed to extreme fire conditions.

It is important to clean the ROP checkvalves and actuation lines with compressed air
before installation to ensure no debris is left inside the lines that could later cause
contamination on the check valve seats.
After installation and prior to pressuring the system perform the “actuation Pipe Work
Test” as detailed in the maintenance and Parts List Manual.

               INSTALLING THE ETI FIRE ALARM PANEL



 The Fire Alarm Panel should be installed at a safe but accessible distance from
the operator to prevent injury to the operator in the event of a vehicle rollover.
Refer to the previous section on fire alarms for electrical connections are
installed in accordance with the customers or relevant manufacturers’
specifications.


 It is recommended that a remote actuator be placed in proximity to the alarm
panel.



POWER SUPPLY

 As the alarm panel may control automatic shut down of the engine, and that
function being electrical; consideration should be given to power failures and the
ability of the alarm system to operate when the machine is shut down.


The risk assessment should consider the fire risk as it relates to its operations.
In most cases the risks relate to engines operating at high power and the
protection is required there. In that case the alarm system may not require
battery backup when the machine is stopped as the unacceptable risk is already
removed. The driver is not present so the alarm has no function and the fact the
machine is already shutdown negates the need for the engine shutdown
function.


Some designers of fire system raise the point that the power supply should have
battery backup against the normal power supply being destroyed in the fire and
therefore preventing the alarm and shutdown functions working. ETI
recommends that this be considered in the normal process of risk assessment.
The committee should consider the probability of a fire event occurring that will
prevent the alarm system functioning correctly before the fire system can react
to the fire. In most cases risk assessment will determine this as an improbable
event and rate it as an acceptable risk. In some cases where the risk is regarded
as unacceptable ETI technical can provide advice on battery backup systems.

Notes: Haul trucks in the 100 to 300 plus tonne class normally have V configuration
diesel engines that are turbo charged. Two sensors of similar length to the engine
placed parallel over the top of the engine provide effective fire detection. Some models
have large opening top access panels to give effective access to the engine during
maintenance. It is acceptable to mount the sensors on these panels while giving
consideration to running the hose past the hinge point to allow opening and closing
without problems. Most models use two remote actuators. One must be positioned
within easy reach of the driver’s position. A second is normally mounted near the exit
of the egress ladder such that the driver may use it when evacuating the machine
during a fire or another person may easily access it from ground level. Some larger
models have two ladders and it may be decided to increase the quantity to three to
allow for an actuator at the bottom of both ladders.
Automatic engine shut-down is recommended. Engine shut-down will affect braking
and steering. For driving safety the delay in operation may be increased from 6
seconds if the operators decide this is inadequate to stop the machine in that time,
particularly with heavy loads on steep grades. Longer delays of 12 or 24 seconds may
be set on the ETI Alarm.

Notes: Haul trucks in the 100 to 300 plus tonne class normally have V configuration
 diesel engines that are turbo charged. Normally a 50 liter or 85 liter cylinders will be
  selected. These usually far exceed the minimum foam requirement but are selected
  because space allows the taller cylinders and higher safety margins can be achieved
 at minimal extra costs. Some very large models may require two cylinders because of
       considerations to size and risk verses machine value. Normally a ring main
    surrounds the top of the engine which may be built of 12mm stainless steel tube,
  12mm nominal bore SAE100R1 hose or a combination of both. A branch line down
      each side of the engine with twin end of line nozzles will provide effective side
 coverage. Larger engines may require two branch lines each side. Attention should be
  given to coverage over fuel pumps and starter motors. Starter motors are a common
     cause of fire with cable burn out and foam should be concentrated here as it is
 acceptable to use on low voltage equipment. Turbo chargers are also a major ignition
 point for fires. It is good installation practice to layout nozzles to overlap on the turbo
    charger(s). This gives extra quenching effect which is a key feature of water based
   foams. Nozzle quantity varies according to the design calculations but a total of 11
 nozzles for 100 tonne class, 12 – 15 nozzles for 150 tonne class and 24 for 300 tonne
                            class are typical design requirements.

                       TYPICAL INSTALLATIONS – DOZER

Bulldozers are usually track type and work mainly by thrust from the tracks pushing
the blade forward. Therefore hydraulic functions tend to be secondary by pre-
positioning the blade and other functions such as a rear ripper. The main fire risk
therefore tends to be simple being the engine environment. Many risk assessments
also regard the transmission area under the cabin as a significant enough risk to
warrant extra coverage in this area requiring an extra branch from the engine fire
system and usually requiring two or three nozzles extra. This transmission area is not
usually regarded as a high risk for a fire to start here so detection is not usually added
in this area. Bulldozers are subject to very high abrasion and impact down low with
the blade and the track system capable of kicking up some rather large rocks. The
most common place to mount the foam cylinder is on the roll over protection system
more commonly known as the ROPS. This mounts the cylinder up out of harms way.
While it does put it at the driver’s level, the vision impairment is usually minimal as it
is behind the ROPS anyway. Most dozer manufacturers have very strict structural
rules with the ROPS as it is a safety device protecting the driver in a roll over. Welding
is normally prohibited so it is most common to build a clamp-on attachment that will
adapt the foam cylinder to the ROPS competently. It is important that the designer and
estimator confirm this and allow this extra work if this is required.



Smaller dozers tend to have straight six cylinder diesels and larger dozers tend to have
larger V engines up to around 700Kw. Most dozers are turbo-charged being the most
likely ignition point for fires. Dozers also have heavy skid plates underneath because of
the rugged use and therefore the assuming a sump under the engine in the foam
calculation is wise. Fires have also been known to start in dozers where a build of say
coal under the engine comes into contact with the front pulley and friction causes
ignition.



Most small to medium sized dozers can be protected by a 35 litre cylinder with a total
nozzle requirement not exceeding say eleven. Some larger dozers like the Caterpillar
D11 or the Komatsu D475 will require more coverage with around 13 or 14 nozzles
and a 50 litre cylinder.

                     TYPICAL INSTALLATIONS – GRADER


Graders usually have turbo charged six cylinder engines ranging up to 400 KW and are
usually turbo charged. The machine performs its work by mechanical thrust from the
drive wheels to the blade. Hydraulic functions are secondary for blade positioning and
the like. Unacceptable fire risk is usually confined primarily to the engine environment.
As such the fire system is usually simple with a simple ring main of nozzles around the
top of the engine and a branch line down each side to provide side engine protection.
For detection, sensors are usually simple provided impairs over the top of the engine.
The main foam cylinder is often mounted on the side of the engine cowling at the rear
of the engine bay. This elevated position helps keep the cylinder away from potential
damage by rocks that are common in the graders work environment.

Graders can travel at reasonable road speeds and so it is wise to consult the operator
as to automatic engine shutdown and whether 6 seconds may need to be extended to
12 seconds if safety is a concern.

                 TYPICAL INSTALLATIONS – WHEEL LOADER

Wheel Loaders are very versatile machines and as such are made from the smallest
sizes to very large sizes. Generally they perform their work by thrusting a bucket
forward using the mechanical force generated from rubber tired drive wheels. They
then use hydraulically transmitted power to lift the loaded bucket to a height where it
can be tipped into say a waiting truck. Smaller models tend to steer using rear wheel
steer and larger models tend to use a pivot point just behind the front wheels for
steering.

Large models tend to have substantial deck space to the rear of the driver’s cabin and
this usually allows the selection of a taller cylinder like the 85 liter capacity to
maximise available foam. Engines vary greatly too with 6 cylinder engines common in
smaller models with larger vee engines in larger models. Turbo charging is usual and
therefore their fire risk can tend to be high as can be the capital value and production
value at risk from fire.

Installations are straight forward with two sensors parallel over the top of the engine. A
remote actuator in the cabin is normal together with one at the egress point. On larger
models a third remote actuator may be recommended where there is an egress point on
both sides of the machine. Also some large models may need some extra protection on
the hydraulic hoses and equipment area just forward of the engine at the steering
pivot. This is easy to organize as a simple branch from the engine system.

Wheel loaders rarely travel fast as they tend to remain in the dig and load area and so
engine shut down at only 6 seconds will normally be acceptable.

                     TYPICAL INSTALLATIONS – DRILL RIG



Diesel powered track driven drill rigs are used extensively in mining and quarrying.
Their most common application is for blast-hole drilling. Their track system allows
them to traverse slowly over rugged terrain. In position they can their tilt the drilling
mast vertically. These machines work hard in very noisy dusty environments. They do
come in a variety of sizes and again manufacturers use a variety of different engine
packs; however turbo charged vee engines are the most common.


There is usually a large high capacity compressor and hydraulic pump coupled to the
engine. A risk assessment is recommended to be undertaken to establish what level of
foam coverage is needed for other equipment.


Drill rigs are high fire risk machines with many reported fires. They have peculiar risks
with reports of unusual events like a hydraulic hose bursting on the mast and
spraying oil over the hot engine from high up.


There would be little doubt that the engine is the primary risk but hydraulic pumps
and compressors are also candidates for additional consideration in foam delivery.


Drill rigs require special attention from the designer, estimator and installer of fire
systems. This is because usually the engine is mounted in the open space above the
chassis of the machine approximately at its center or slightly rearward. This means
there is no superstructure from which nozzles and piping can be mounted.


ETI recommends; that in this case, a simple steel frame is fabricated, that will meet the
requirements of the designer, to mount and position nozzles, as well as the overhead
fire sensors. Special liaison will be needed with the client to ensure that this
fabrication minimizes or avoids impact to operational, safety and maintenance
considerations.



Normally the deck space allows for the fitment of a tall high capacity cylinder and so
the 85 litre capacity is a popular choice.

                     TYPICAL INSTALLATIONS – EXCAVATOR


Diesel powered hydraulic excavators and *back hoes are perhaps one of the most
useful and therefore common type of machine in the market today. They are found
virtually everywhere where material needs to be dug and loaded. We see them in road
building, construction sites, quarrying and mining, just to name a few of the more
common applications. As such we see them in a variety of sizes from tiny one man ride
on machines right through to 500 tonne plus heavy units. Because fire protection
becomes more feasible and indeed necessary as machines get larger and more costly; it
is the medium to large machines we are primarily concerned with. In performing a risk
assessment on a large excavator, the people involved need to consider not only the
high capital value of these machines but the potentially much higher production loss
from a fire. For example; if a mining operation had a $2 million excavator that worked
loading twelve haul trucks that were each worth $1 million dollars, then this particular
fleet has a capital value of $14 million dollars. If it loses a haul truck to fire it has lost
7.1% in capital and 8.3% in productivity. If the excavator is lost, it has lost 14.3%
capital and 100% of its productivity because the trucks cannot be loaded. Large
excavators are not in stock just down the road at a dealer’s yard. It may take six,
twelve months or more to rebuild or replace it and the production losses can be
crippling.

What also makes these machines higher in fire risk is the fact that they are completely
hydraulic powered. Add to that the fact that hydraulic pressures have dramatically
increased to increase performance and fires in the hydraulic equipment have become
much more common. Many large machines have two engines thereby doubling the
probability of an engine fire. NOTE: the ETI training module examines the theory of
mechanical vaporization of hydraulic oil into a volatile fuel. Refer to training notes.

It is for the above reasons that large excavators deserve high safety factors. Strong
attention is needed on what equipment should be also protected by foam coverage.




SPECIAL NOTES AREAS TO PROTECT

Apart from the engine(s), there is usually a large high pressure hydraulic pump
coupled to the engine. It is recommended that this be added to the design as part of
the engine calculation and noted so. In large high pressure hydraulic machines, it is
recommended that the risk assessment consider hydraulic equipment on the deck area
between the engine(s) and the boom. This is usually above the pivot of the machine. In
this area we find valve banks and control equipment. Previous fires have been known
to occur in this area due to mechanical vaporization of hydraulic oil from a failure of a
hose or seal.

                                                                                   Page 112 of 131

The vapor may find its way to the engine compartment and ignite from the turbo
charger or exhaust and then flash immediately back to the source. In this case an
engine fire suppression system cannot help because the engine has only acted as an
ignition source. The actual fire is now at the point of the hydraulic fault. The result is
like a flame thrower where with large amounts of vaporized fuel erupting from the fault
and the fire is instantly large and spreads quickly.

The best method of fighting this fire is engine shut-down as quickly as possible to stop
the flow of oil at high pressure. We can then fight the residual fire as a normal class B
fire. If the foam fire system has already been designed and installed, it can deliver foam
over these areas at the required rates and experience has shown that this is effective in
defeating this type of fire.

ENGINE SHUTDOWN

For the reasons described above, engine shut-down is vital to defeating a high pressure
hydraulic fire. Experience has shown that driver’s of these machines may panic and
not go through safety procedures for engine shut down. These fires can be extremely
large and sudden and it is a normal human reaction to exit the scene quickly without
regard for procedures. Therefore automatic shutdown is highly recommended.

FIRE DETECTION

For automatic engine shutdown and fire suppression, it is necessary for the fire system
to detect the fire. In the case of the engines, the ETI sensors provide a reasonably high
probability of prompt detection. This is because the potential fire is fairly closely
predicted in location. The hot engine has already pre-heated the sensors and the
enclosed environment facilitates a fast rate of temperature rise. There are design and
operational issues that need to be discussed with the client in regard to fire detection
in the hydraulic equipment areas. If the location of a potential fire can be accurately
predicted then ETI fire sensors may be placed in this area. In reality though, these
areas are large and open and in most cases an accurate prediction of exactly where the
fire will concentrate cannot be made.

This makes in many cases the use of the standard sensors not practical. The open
environment also works against them as the heat buildup is not concentrated and
neither is the sensor pre heated. A successful method that has been used for this is an
advanced optical detector mounted to scan this area. These detectors work something
like a security camera that can see fire and trip the fire alarm in that event. They are
made to work in very rugged environments and can give very reliable performance
when properly engineered. Because of their wide field of vision they can scan the large
open area where this hydraulic equipment is located and instantly trip the fire alarm
even from a very small fire. If this type of detection is needed to interface with the ETI
fire system, then the ETI technical department should be contacted to support this.

Note the following system layout for fire detection that the two pairs of engine sensors
are long type, which can extend past the engine and over the pump. Also both pairs
engine sensors meet at one large manifold as do the two remote actuators. The
actuating line then branches into two to actuate all the foam cylinders. In this case
two. This means that if either engine system detects fire, or if a remote actuator is
used, both engines and the hydraulic equipment will receive foam discharge. This is
the most common way as building two independent systems is possible but
operationally it is considered too confusing for the operators. For example if the
operator saw a fire it may be difficult in the smoke to identify the correct engine or he
may actuate the wrong actuator. Having a common actuation system here makes
sense as it eliminates mistakes.


FOAM QUANTITY AND NOZZLES

As described above, large high risk machines may justify more conservative design
decisions. More foam will extend the discharge time and increase the fire fighting
potential of the fire system. These large machines also usually have a lot of deck space
where a number of cylinders can be mounted. Two large 85 liter cylinders are common
in medium machines and larger machines have been known to have three to five of
these cylinders to give exceptional foam supply. Remember to include the hydraulic
pump coupled to the engine as part of the engine area calculation. Other equipment
can be simply calculated as a separate risk to arrive at a total area to be protected.

Note on the following drawing of the foam system that the two engine systems are
connected. This is recommended as it will help with foam distribution. If the foam
quantity is well in excess of minimums as recommended, this also protects against a
single foam cylinder failure as the system may still have the capacity to deliver foam
throughout effectively.

MANUAL ACTUATION

A minimum of one remote actuator at the driver’s position is recommended. Many
large excavators have a ladder on both sides of the machine and in this case a third
remote actuator is recommended. Some large excavators have a tail boom that drops
down behind the machine when being serviced. Sometimes a remote actuator is placed
here too so that actuation from ground level is possible. In normal operation, actuation
from ground level on large excavators is not possible due to the size of the machine
and the impediment of the track system.




FOOTNOTE: * Backhoes are usually identical to excavators for fire protection. These
often the same basic machine and only vary by the layout of the bucket which digs by
sweeping rearward instead of forward.

      CHAPTER 14 - COMMISSIONING THE FIRE SYSTEM



The ETI design program generates a comprehensive check list that forms a
“Certificate of Completion”. It documents precise requirements for each and
every design. It also forms the official document record for all parties and has a
sign off area. See the following example.


The steps outlined in this example are required by AS 5062-2006 and must also
form part of the maintenance record with the design documents.


It is vital that the installer satisfy himself that each and every component is
tested to his satisfaction and that he is confident that all aspects of the system
are in proper operating order.


A discharge test is required by AS 5062-2006 and is also mandatory under ETI
rules.


Other requirements of AS 5062-2006 include recording the specification and
location and aiming point of each and every discharge nozzle. See page 1.


DOCUMENT HANDOVER


The agent selling the system must provide an “Operation and Maintenance
Manual”. Please refer to AS 5062-2006 10.5. Most of the documentation is
generated from the ETI design package, but the overall manual is the
responsibility of the agent. Of note is to provide a functional description of the
system ref 10.5 (b). Also, drawings of the installation are mandatory Ref 6.2 and
are the responsibility of the designer. They must be included as part of the
design record.

The Following three pages give an example of the “Certificate of Completion”
generated by the ETI version 11 design program.

PERIODIC INSPECTION

This is referred to in AS 5062-2006 as the six monthly inspections because that is
the MAXIMIN interval it may be performed. From experience ETI recommends that
this period of inspection must be shortened where operating conditions indicate.


As a result of this the ETI service procedure requires the customer to indicate what
service conditions the machine works in, to set the maximum intervals between
services. To assist in this process ETI provides a qualitative guide which instructs
what service interval minimum would be appropriate. See extract below from page
two Periodic Service Schedule.




Therefore 6 months is the maximum service interval. The minimum may be as low
as one month depending on operating conditions. The customer nominates the
working conditions and the service interval must then be set in the records. The
design program allows for this to be entered on page 2 where the working
conditions have already been considered. The designer should recommend the
interval, but it is ultimately the customer’s choice.




Please note that some service requirements detailed in the ETI schedule exceed AS
5062-2006 e.g. ROP systems must have the pneumatic actuating pipework flow
and pressure tested at every periodic inspection.

ANNUAL INSPECTION AND TEST

  This procedure meets and exceeds the Periodic inspection and therefore may
  substitute it when it is done. It is a similar procedure to the Periodic service with
  additional inspections and tests added, and of most note, there is a full actuation
  and discharge test. This provides the opportunity to do the required internal
  inspections in the foam cylinders required by the standards invoked. It also allows
  for the foam system valve to be stripped and inspected. The valve must have new
  seals and burst disk membrane fitted. Re-lubricate and check function before being
  re-fit.

CHARGING FOAM CYLINDERS

After the actuation system has been tested, the foam cylinder is filled with the
correct quantity of potable water and foam solution, the filler plug is then replaced
and tightened. The regulator assembly is mounted on the nitrogen cylinder with the
outlet hose and Schrader adaptor. Set the pressure at 13.7 Bar. At this point the
dual actuation valve should also be fitted and set with the piston in the closed or
normal position for charging.

Commence charging at the Schrader connection on the side of the valve. DO NOT
CHARGE THE CYLINDER AT THE FILL PLUG. This will cause foam solution to
move up the pickup hose. Particularly if an LOP system is connected, this will
cause foam solution to travel out into the actuation pipework. The Schrader
connection is provided at the fill plug as a means of de-pressurising the cylinder
without discharging the foam contents. Occasionally this is done because a leak
needs to be rectified or some other maintenance.

Pressurise the cylinder through the valve connection. When the cylinder is fully
charged to 13.7 Bar check the indicator on the valve to check that it is now
indicating correct normal pressure. Remember that the indicator gauge on the
valve is just an indicator. The calibrated gauge on the charging regulator is the
most reliable pressure reference.


TESTING ROP ACTUATION SYSTEMS

Rise of Pressure (ROP) actuation systems should be tested as follows at completion
of installation as part of the completion certificate sign off and also at all periodic
and annual service checks.

WARNING: ROP actuation pipework is not pressurised in the normal condition.
This means that there is no symptom or warning system to warn of a fault. ETI
design rules therefore require a minimum of two sensors for automatic detection
and two manual actuators for manual actuation. This provides double redundancy
against a system failure. Nevertheless, good completion checks and service
procedures also guarantee reliability.

When the actuation system has been installed and completed, the pipework test is
done as follows. Disconnect the actuation hose at the ROP actuation nipple on the
dual actuation valve. Connect this hose to the 25 Bar. test gauge supplied in the
test kit. Disconnect ALL actuation devices at the outlets of the remote manual
actuators and the filters of all fire sensors. Using the Outlet hose from the charging
regulator, connect this to each point in turn using a 7/16” JIC nipple. Apply a
pressure of approximately 12 Bar. On each test the following procedure is to be
carried out. Check that the same pressure is being indicated on the test gauge at
the valve actuation point. Using soapy water, check all joints for leaks and correct

as necessary. At this time check valves can be observed to confirm pressure is not
flowing against the seats.

When it is believed there are no detectable leaks, isolate the pressure supply and
confirm that the test gauge does not show any visible drop in one minute. When
each actuation device has been tested, ensure all devices are re-connected and the
actuation hose is re-connected to the valve.


TESTING LOP ACTUATION SYSTEMS

Loss of Pressure (LOP) actuation systems should be tested as follows at completion
of installation as part of the completion certificate sign off, and also at all periodic
and annual service checks.

LOP actuation pipework is pressurised in the normal condition by pressure by-
passing through the dual detection valve. This means that the pressure in the
actuation circuit is the same as the foam cylinder. This is known as a supervised
system because the low pressure switch will cause the alarm to give a fault
warning to the operator if the foam cylinder and actuation system lose substantial
pressure.

AFTER INSTALLATION
When the actuation system has been installed and completed, the pipework test is
done as follows. It is important to pressure test the actuation system before
connecting to the foam cylinder and charging it. This will avoid the difficulties of
needing to de-pressurise the charged cylinder when leaks or faults are found.

Disconnect the actuation hose at the LOP actuation nipple on the dual actuation
valve. Using the Outlet hose from the charging regulator, connect the LOP
actuation hose using a 7/16” JIC nipple. Apply a pressure of approximately 12 bar.
Using soapy water, check all joints in the actuation system for leaks and correct as
necessary.

When it is believed there are no detectable leaks, isolate the pressure supply and
confirm that the regulator gauge does not show any visible drop in ten minutes.

IMPORTANT Leaks even if small in LOP systems will cause the system to slowly
de-pressurise. This will cause frustration to customers due to interruptions to
production and extra maintenance costs. Well installed, leak free pipework
prevents these frustrations.

SERVICE CHECKS Because LOP systems are supervised by the alarm system,
there is no pressure test during periodic servicing. This check is a simple
procedure of confirming that all the pressure indicators are normal as well as a
close visual inspection of pipework for serviceable condition.
