Locating the Alarms
Heat Alarms are intended to be supplementary to Smoke
Alarms and should only be placed in areas where smoke alarms
cannot be used.
This heat alarm is a multiple station heat alarm and can be
connected to other alarms of the same make and type. This in-
terconnect feature allows up to 40 Heat Alarms and / or Smoke
Alarms to be connected together over 150 metres maximum,
using the single white wire, and thus allowing all alarms to
sound when anyone is activated.
This Heat Alarm cannot be connected to any other device such
as a fire alarm panel.
This Heat alarm gives a fire warning when the temperature at
the unit reaches 60ºC. It is ideal for kitchens, garages, cellars,
boiler rooms, attics and other areas where there are normally
high levels of fumes, smoke or dust which preclude the use of
Smoke Alarms due to the risk of false alarms.
All the Heat Alarms and Smoke Alarms should be intercon-
nected to ensure the early warning will be heard, particularly
by somebody sleeping. A properly designed early warning fire
system ensures the alarm is given before the escape routes
become blocked with smoke. Therefore there must be Smoke
Alarms along the escape routes as Heat Alarms would not
give sufficient warning. However, a fire in a closed room (e.g.
kitchen) adjoining the escape route, can eventually cause the
corridor to become smoke-logged due to smoke leaking out
from around the door before adequate warning can be given by
detectors in the corridor. A heat Alarm in the closed room may
give early warning offire in that room.
If your dwelling is on a single storey, for minimum protection
you should fit a Smoke Alarm in a corridor or hallway between
the sleeping and living areas. Place it as near to the living areas
as possible and ensure the audible alarm can be heard when the
bedrooms are occupied. See Figure 1 for examples.
If your dwelling is multi-storey, for minimum protection one
Smoke Alarm should be fitted at the bottom of the staircase
with further alarms fitted on each upstairs landing. This
includes basements but excludes crawl spaces and unfinished
attics. See Figure 2 for examples.

Positioning the Alarms
Ceiling Mounting
As hot smoke rises and spread out, it is advisable to mount on a ceiling in a central
position. Avoid areas where there is no air circulation, e.g. corners of rooms and
keep away from items which may prevent the free flow of air. Place the unit at
least 300mm from and light fitting or decorative object which might obstruct
smoke / heat entering the alarm. Keep at least 300mm away from walls. See
Figure 3i.
WallMounting
Do not mount tight into the corners. Put the top edge of your smoke alarm between 150 and 300mm below the ceiling.
Keep at least 300mm from room corners. See Figure 3i (Wallmounting is not recommended for Heat Alarms).
On a Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke Alarm 900mm from the highest point measured horizontally
because “dead air” at the apex may prevent smoke from reaching the unit. See Figure 3ii.
Areas to be avoided include the following:-
•
Situations where the temperature may fall below 4oC or rise above 40oC
•
Humid areas such as bathrooms, kitchens, shower rooms where the relative humidity may exceed 90%
•
Near a decorative object, door, light fitting, window molding etc., that may prevent smoke or heat from entering the
alarm.
•
Adjacent to or directly above hot components such as radiators or wall vents that can effect the direction of air
currents.
•
In very dusty or dirty environments such as workshops.
•
Locate unit at least 1.5m and route wiring at least 1m away for fluorescent light fittings as electrical “noise” and/or
flickering may affect the unit. Do not wire into the same circuit as fluorescent lights or dimmers.
•
Do not locate in insect infested areas. Insects and contamination on the Heat Alarm sensor can increase its response
time.
Installing the Heat Alarm
WARNING – This heat alarm is mains powered and requires wiring by a qualified electrician in accordance with the
current IEERegulations for ElectricalInstallations (BS7671).
The circuit used to power the heat alarm must be a dedicated permanent supply that cannot be switched off accidentally
by the normal user. Before installing ensure the electrical supply is isolated.
WARNING : To prevent injury, this heat alarm must be securely attached to the ceiling/wall in accordance with the
installation instructions.
The Heat Alarm will function correctly either as a stand-alone alarm orinter-connected.
All inter-connected Heat Alarms must be supplied from a single power circuit.
A common neutral must be used for the interconnect to function.
Do not connect the Inter-connect wire to Live or Neutral.
•
Disconnect the AC main power from the circuit that is going to be used.
•
Having established the mounting location install a junction box suitable for locating the termination point. Ensure that
there is no other electrical wiring or pipe work in the area adjacent to the mounting surface.
•
Unlock the detector unit from the base by pushing up the temporary latch with a screw driver. See Figure 4.
•
Fix mounting plate in position.
•
Strip the Live/Neutral and Inter-connect (if used) wires.
•
Connect the wires to the correct terminals (on the mounting plate) to incoming supply. If the smoke alarms are to be
interconnected, link out the interconnection terminals. Ensure the screws are fully tightened. See Figure 5.
•
The alarm must be wired in accordance with National wiring codes.
LIVE : connect to house wires coloured Brown, Red or marked with L.
NEUTRAL : connect to house wires coloured Blue, Black or marked with N.
INTERCONNECT : connect to the third wire. If you are not interconnecting to other units, do not connect any wire to this
terminal. Never use an EARTH wire for interconnect wire.
•
Insert a 9V battery firmly into battery compartment on the rear of the alarm. NOTE POLARITY OF CONNECTIONS.
Ensure the metal tab is fully depressed when the battery has been fitted.
NOTE – For the safety of the end user the smoke alarm cannot be fitted without its battery.
•
Before assembly to base plate test the correct operation of the smoke alarm (operating from the battery only) by
depressing the test button on the front of the alarm. The unit should emit a loud pulsating alarm.
•
Assemble alarm onto the mounting plate by sliding it in according to the direction of the arrows.
•
Restore the AC supply.
•
Test the correct operation of the smoke alarm by depressing the test button on the front of the detector. The unit should
emit a loud pulsating alarm.
•
Should use 2.1mm wire for connection.
WARNING: Connection to the EARTH terminal is not needed for correct functioning of the Smoke Alarm. It is just for
conveniently terminating any earth supply wire coloured green or green/yellow. It does not provide protective earthing for
the Smoke Alarm.
Operating your Heat Alarm
Once the heat alarm has been installed a small GREEN indicator light (LED) should be visible through the alarm grill
indicating that AC supply is healthy. A RED indicator light (LED) should also flash approximately once a minute to
indicate the battery is healthy and the unitis operating properly.
When the Heat Alarm senses temperature above 60ºC (plus or minus a few degrees), the unit will emit a loud (85dB)
pulsating alarm until the temperature drops below 60ºC. During the alarm condition,the RED indicator light (LED)will
flash quickly.
Testing your Heat Alarm
It is recommended that you test your Heat Alarm once a week to ensure the detector is working correctly.
Push and hold the test button for approximately 3 seconds. A loud pulsating alarm should sound and a RED flashing
indicator light (LED)can be seen to indicate the correct function.
NOTE – for multiple interconnected Smoke / Heat Alarms, only the RED indicator light (LED) of the originating unit will
flash rapidly. All other units in the interconnect system will sound an alarm but their RED indicator light (LED) will NOT
flash. Test each alarm checking that the alarm is triggered on all other alarms installed.
Maintaining your Heat Alarm
A fresh battery should last for approximately one year. If the Heat Alarm emits a short ‘beep’ once a minute the battery
is at the end of its life and should be replaced immediately. This low voltage warning will be given for at least 7 days. If
the red indicator light (LED) does not flash every minute then replace the battery.
Clean your alarm at least once every six months to prevent dust build up. This can be done using a vacuum cleaner with
the brush attachment. Clean gently around the front grilled section and sides.
WARNING : The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases,
shall be placed on the apparatus.
Battery Replacement
Always TURN OFF the A.C. supply to the Heat Alarm before replacing the battery. Replace the battery at least once
annually, or immediately when the low battery signal sounds once a minute, even though the Heat Alarm is receiving
A.C.power.
Test the alarm for correct operation using the test facility whenever the battery is replaced.
WARNING: DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED. THE USE OF BATTERIES
OTHER THAN THOSE RECOMMENDED ON THE BACK OF THE HEAT ALARM MAYBE DETRIMENTAL TO ITS
OPERATION.
The battery should only be replaced by a qualified electrician or similarly qualified person.
•
Turn off the A.C. power supply to the Heat Alarm.
•
Gently slide the smoke alarm out from the mounting plate.
