                                       WIRELESS MULTI-CRITERIA DETECTOR


GENERAL DESCRIPTION

The HFW-MA-01 wireless Multi-Criteria Detector (Detector) has been designed to fully meet the requirements of
European Standard EN54-5 and EN54-7. The advanced design of the smoke inlet of the optical chamber guarantees a
very high rejection to the introduction of dust, effectively increasing the time between maintenance periods.
An alarm condition is determined when either smoke levels inside the chamber exceed the alarm threshold, or when
the temperature level or thermal variation versus time (Rate of Rise) exceeds the alarm threshold. Consequently an
alarm message is sent to the Fire Control Panel (FCP) via HFW-W2W-01 Translator Module / HFW-EM-01 Expander
Module.
Communication between the Detector and the Translator Module / Expander Modules is achieved via a wireless,
analogue-intelligent bi-directional protocol. Radio communication meets European standard EN 54-25.

DEVICE POWER SUPPLY AND PROGRAMMING
The programming operation permits the configuration of the Detector on to the wireless system. The programming
operation described below does not change if carried out directly at the Translator Module or if programming is
carried out using the Wirelex PC configuration tool.
1) Insert the secondary battery.
2) Move the “Program” switch to the “ON” position. Insert the primary battery.
NOTE 1: Ensure that the polarity of both batteries is correct
3) The Detector LED will flash RED four times. After the four RED flashes, move the “Program” switch back to the “1”
position.
NOTE 1: When locally programming the Detector on to the Translator Module, the Detector will learn on in its
default mode of “Fixed – Rate of Rise”. If the installation needs a Thermal Detector in another mode, the Wirelex
Configuration software must be used to program the device.

   IMPORTANT NOTE!
   Programming is considered to be successful only if there is an indication of programming success on the Translator
   Module (the address will appear in the LCD) or on the “Configuration” tab of the Wirelex program (a “+” will appear in
   the “Prog” column along with a small window stating “Successful programming”)
   If the programming operation fails, check if mistakes were made at the Translator Module (e.g. wrong device type
   selected) or in the Wirelex Configuration Tool, remove the batteries, flick the “Program” switch alternately between
   “ON” and “1” a few times in order to discharge the internal capacitor and then start the programming process again.
   FAULT SELF-TEST
   The Detector periodically performs a self-test and, if a fault condition is detected, a fault message is sent to the Fire
   Control Panel via the Translator Module / Expander Module.
   The fault condition is locally signaled by the visual LED indicator located at the center of the detector.
   A fault condition is considered to be present if:
     a) Fault on the thermal electronic circuitry.
     b) High level of contamination inside the optical chamber..
     c) Low batteries level.
     d) Tamper.
   LED INDICATOR
   The Detector is equipped with a bi-colour LED (red/green) that provides visual indication for functional conditions and
   battery levels as indicated in the table below:

COMMUNICATION QUALITY ASSESSMENT
It is possible to assess the wireless communication quality between the Detector and Translator Module / Expander
Module by using a testing feature built into the device. After a successful programming procedure, changing the
“Program” switch to the “ON” position, the device LED will start blinking according to the table below.
                    Communication quality                          Assessment             Device’s indication
Link margin is less than 10 dB                                   Fail                Two red blinks
Link margin is from 10 dB to 20 dB                               Poor                One red blink
Robust communication with link margin from 20 dB to 30 dB        Good                One green blink
Robust communication with link margin over 30 dB                 Excellent           Two green blinks
 Always remember to reposition the switch to “1” after the assessment operation: device is NOT operational with the
switch set to the “ON” position.
BATTERY FAULTS
If a battery fault condition is detected on the Detector, a fault message is sent to the FCP via the Translator Module /
Expander Module.
TAMPER DETECTION FEATURE
The Detector is fitted with a tamper detection switch. In case of removal of the device from its base, it sends a tamper
detection message to the FCP. For this reason be sure that the device is well secured, tightened and locked onto the
base.
WIRELESS DETECTOR ANTI-TAMPER BLOCK AND REMOVAL
The base for the Detector has a special anti-tamper device lock. To lock the sensing device onto the base, cut off the
small plastic lug on the plastic blocking grip on the detector base (see picture below).

            LOCKING LUG                                                                     Hole to unlock the detector




Remove the small plastic lug on the plastic blocking grip, to enable the Detector lock.
To remove the locked Detector from the base, insert a tool, like a small screwdriver, into the hole and remove the
Detector.
TESTING
The Detector has been designed to be tested using a magnetic functional test. When the test is performed with an
appropriate magnet, a fire alarm message is sent to the FCP via the Translator Module / Expander Module.
To perform the magnet test, place a magnet near the surface of the indicated area (see below).




                                                                                     MAGNET TEST AREA

                                                www.acornfiresecurity.com
                                                   www.acornfiresecurity.com




The Detector must enter into alarm condition, activate the central LED indicator and transmit the alarm message to
the FCP.
After each test, the Detector must be reset at the FCP or using the local facility at the associated Translator Module.
The Detector must be reset by the specific command on the Fire Control Panel.
All devices must be tested after installation and on a periodic basis.
DEVICE PLACEMENT
In order to avoid a consistent degradation of the distance and quality of the wireless communication between the
Detector and the Translator / Expander Module, place the Detector as far as possible from metal objects (for example
metal doors, windows, openings etc.), other electronic devices, computer equipment and cable conductors.
Follow this procedure for placing the Detector:
1) Select the position of the Detector before installing and fixing it. Verify, from that position, that the communication
between the device and Translator Module / Expander Module is correctly established and working (see the
Communication Quality Assessment paragraph).
2) Install and fix the Detector base in the selected position.
3) Fit the Detector to the base ensuring it is fitted correctly.
WARNINGS AND LIMITATIONS
1) The Detector uses high quality electronic components and plastic materials that are highly resistant to
environmental deterioration. However, after 10 years of continuous operation, it is advisable to replace the devices in
order to minimize the risk of reduced performance caused by external factors. Ensure that this device is only used
with compatible control panels.
2) Detection systems must be checked, serviced and maintained on a regular basis to confirm correct operation.
3) Refer to and follow national codes of practice and other internationally recognised fire engineering standards.
4) Appropriate risk assessment should be carried out initially to determine correct design criteria and updated
periodically.
WARRANTY
All devices are supplied with the benefit of a limited 3 year warranty relating to faulty materials or manufacturing
defects, effective from the production date indicated on each product. This warranty is invalidated by mechanical or
electrical damage caused in the field by incorrect handling or usage.
Product must be returned via your authorised supplier for repair or replacement together with full information on any
problem identified.
