Generations of Fire Alarm Systems
Generations of Fire Alarm Systems
• Conventional system
• Not always the low cost solution
• Addressable system
• A good intermediate step
• Intelligent addressable system
• An ideal solution
Conventional Systems
• One-way communication
• Uses voltage change for the
communication signal
• “Short” = Alarm
• “Open” = Trouble
• Zone only identification
• General (non-specific) location
Addressable Systems
• Two-way communication
• Device address is identified and
communicated to panel
• Panel polls the device
• Device in alarm or non-alarm condition
• Can signal alarm, trouble, or maintenance
requirement
• Pinpoints hazard via display at control panel
• Programmable input-to-output activation
Analog Systems
• According to the National Fire Alarm Code
Handbook, an analog system uses
devices which transmit signals indicating
varying degrees of condition, as opposed
to just alarm and trouble
• This is only a portion of a true intelligent
addressable system
Intelligent Addressable Systems
• Two-way communication
• Device address and “vital signs” are identified
and communicated to panel
• Device status (alarm/trouble)
• Smoke levels (normal/pre-alarm/alarm)
• Compensation for dust accumulation (specific
sensitivity levels)
• Integrity of the device’s electronics
• Programmable input-to-output activation
• Control panel compiles the information and
decides specific action
Intelligent Addressable Fire Alarm
System Components
Intelligent Addressable Controls
Intelligent Addressable Controls
• Utilize “Signaling Line Circuit” (SLC) Loop
wiring, connecting all addressable input
and output devices to the addressable
control along the same pair of wires
• Conversely conventional systems use IDC
and NAC wiring, which requires individual
cable runs for each function
Typical SLC Arrangement
Intelligent Addressable Controls
• Each protection point (e.g., detector, pull
station, etc.) has a unique number
assigned to it called the address for
reporting alarms and troubles
• Allows the control to distinguish one
addressable device from another
• Displays the address when an event occurs on
that device
Intelligent Addressable Controls
• These controls interrogate each
intelligent device via the SLC or multiplex
loop
• Each device answers the control and then
a decision is made on what, if anything,
needs to be done
Intelligent Addressable Controls
• These controls can also monitor
conventional initiating devices using
addressable monitor modules
• For example, conventional notification
appliances are activated by addressable
control modules
• Serial annunciation and printer options
are generally available for these units
Intelligent Addressable Controls
• System is programmed to activate certain
output devices based on alarm activity
from certain input devices
• The process of linking outputs to inputs in
programming is Software Zoning
Control Panel User Interface
• End-user friendly
• LCD display and alpha-numeric keypad
• LED indicators
• Fire alarm • Maintenance
• System trouble • Disabled point or zone
• AC power on • Battery
• Supervisory • Ground
• Alarm silenced
Remote User Interface
• Liquid crystal display annunciator
• Duplicates the alpha-numeric information
displayed at the panel in multiple remote
locations
System Communication
• EIA-232 for connection to PC for programming
or connection to a serial printer
• Dedicated EIA-485 port for connection to LED-
type annunciators and digital communicators
• Dedicated EIA-485 port (4 data wires & 2 wires
for 24 VDC) for connection to alphanumeric
annunciators
Communication Devices
• Point I.D. digital
communicators
• Report status information
from every intelligent device
in a system (e.g., detectors,
modules, annunciators, etc.)
Communication Devices
• Annunciator relay modules
• Provide fully supervised
control of ancillary systems
(e.g., elevator recall, HVAC
shutdown, etc.)
Intelligent Addressable
Software Features
Intelligent Addressable
Software Programming
• Software allows you to assign activation
of specific output devices in response to
the initiation of specific input devices
Operating System Software
• Non-volatile memory (retained after loss
of all operating power)
• Three levels of user interaction
• Read Status
• No password required
• Programming – Maintenance Mode
• User programmable password
• Programming – Master Mode
• Alarm company programmable password
Operating System Capabilities
• Silence inhibit timer (60 sec. duration)
• Alarm verification per intelligent detector
• Waterflow selection per monitor module
• Pre-signal delay for manual pull stations
• Onboard NAC synchronization
• Saves time and money over wiring individual
sync modules
• Allows the entire system to notify in sync
• Allows you to meet or exceed code
requirements
Operating System
Maintenance and Troubleshooting
• Automatic device type code verification
• Continual automatic detector testing
• Detector sensitivity printout
• Drift compensation
Intelligent Addressable
System Devices
Intelligent Detectors
• Photoelectric
• Photoelectric with heat
• Ionization
• Duct
• Duct with relay
• Heat
• Heat rate-of-rise
Intelligent Detectors
• Automatically adjust sensitivity
levels without the need for
operator intervention or
programming
• Easy-to-use rotary switches for
setting addresses (01-159)
• Example: to set address 119…
• …set the tens switch to “11”
• …set the ones switch to “9”
Intelligent Detectors
• Multi-criteria designs
• Sensitivity increases
with heat
• Combination photo
and thermal
technologies
• Peak/off-peak setting
• Pre-alarm levels

Addressable Input Modules
• Monitor module
• For monitoring a circuit of normally-
open contact conventional alarm
initiating devices

wiring the NAC circuit to an
output module

Voice Evacuation
Voice Evacuation Systems
• For emergency notification
• Use speakers located
throughout a facility
• Communicate specific
instructions to building
occupants
Why Use a Voice Evacuation System?
• Emergencies can be confusing and disorienting
for building occupants
• It is further complicated when in unfamiliar
surroundings (e.g., hotels, auditoriums, etc.)
• Horns, sounders and strobes do not clearly
indicate specific evacuation instructions
• Research shows that the integration of a voice
capability into a fire alarm system provides the
best method for effective evacuation
Why Use a Voice Evacuation System?
• Life safety is the primary purpose of any voice
evacuation system, normally working in
conjunction with the fire detection system
• Voice evacuation systems are generally used to
guide building occupants to safer location rather
than causing a general evacuation, though they
can be used for both
When is a Voice Evacuation
System Required?
• National Codes direct the installation
of a voice evacuation system in
places of assembly greater than 300
people, in multiple-screen theaters
and high rise buildings
• Local authorities often extend this
requirement to facilities with 50 or
more occupants
How are Voice Evacuation
Systems Employed?
• Voice evacuation systems can be integral to an
intelligent addressable fire alarm system or as a
free standing unit
• The voice evacuation system may be connected
to a fire alarm command center from which pre-
recorded or “live” messages can be issued to
individual zones or the entire building
• Some systems have warden stations or jacks on
each floor from which a fire warden or fire
officer can issue evacuation instructions
