1. Basic Information about your Heat Alarm
A Heat Alarm is an early warning device. A system based on in
-
terconnected Heat Alarms and Smoke Alarms, can give you
and your family valuable extra time to escape.
Note:-
·
Install correctly, in the centre of the ceiling if possible.
·
Test weekly with Test Button.
·
Replace alkaline battery yearly or when it beeps once a min
-
ute.
·
When the power is first connected the Alarm may sound for
2-3 seconds - this is normal.
·
A Heat Alarm does not prevent fires.
·
Plan your escape route.
·
Proper fire protection requires Smoke Alarms in addition to
Heat Alarms with all units interconnected.
·
If you have any doubt or query about Heat Alarms consult
the supplier or your local Fire Brigade.
2. Locating your Heat Alarm
The Heat Alarm gives a fire warning when the temperature at the
unit reaches 58° C. It is ideal for kitchens, garages, boiler
houses and other areas where there are normally high levels of
fumes, smoke or dust i.e. places where Smoke Alarms cannot
be installed without the risk of excessive nuisance alarms. A
Heat Alarm should only be used in a room adjoining an escape
route, in conjunction with Smoke Alarms on the escape routes.
All the Heat Alarms and Smoke Alarms should be intercon-
nected to ensure the early warning will be heard, particularly by
somebody sleeping. A Heat Alarm installed in a closed room will
give early warning of fire in that room. A properly designed early
warning fire system ensures the alarm is given before the es
-
cape 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 leak
-
ing out from around the door before adequate warning can be
given by detectors in the corridor. (Smoke leaking out from a
room is often cool and slow moving so it can take a long time to
rise to the ceiling, and travel to a detector which could be some
distance away).
Figure 1 illustrates where Heat Alarms and Smoke Alarms
should be located in a typical two storey house. The following
gives the recommended spacings to be used to ensure the early
detection of fire and that the warning will be heard:
3. Positioning your Heat Alarm
Location must comply with applicable building regulations.
(a) Ceiling Mounting
Hot smoke rises and spreads out, so the Heat Alarm must be put
on the ceiling - preferably in the centre. The sensitive element (in
the cylindrical protrusion) must not be less than 25mm (1 inch)
or more than 150mm (6 inches) below the ceiling or roof.
The air is “dead” and does not move in corners, therefore Heat
Alarms must be mounted away from corners. Place the unit at
least 30cm (12 inches) from any light fitting or decorative object
which might obstruct the heat
travelling to the Alarm. Keep at
least 15 cm (6 inches) away
from walls and corners. (See
figure 2). Wall mounting is not
recommended for Heat
Alarms. If the ceiling has a
pitched roof install an Alarm
within each apex.
(b) Locations to Avoid
Don’t place your Heat Alarm in any of the following areas:
·
Places where extremes of temperature may occur - below
4°C or above 43°C. e.g. attics, furnace rooms etc. Directly
above ovens or kettles as the heat/steam could cause nui
-
sance alarms.
·
Bathrooms, shower rooms or other rooms where the unit
may be triggered by steam or condensation.
·
Near a decorative object, door, light fitting, window
molding etc., that may prevent the heat reaching the unit
·
Surfaces that are normally warmer or colder than the rest
of the room (for example attic hatches, uninsulated exterior
walls etc).
·
Next to or directly above heaters or air conditioning
vents, windows, wall vents etc. that can change the direc
-
tion of airflow.
·
In very high or awkward areas (eg. over stair shafts) where
it may be difficult to reach the alarm for testing and battery
replacement.
·
Locate the unit at least 1 metre (3 feet) from dimmer con
-
trolled lights and wiring - some dimmers can cause inter
-
ference.
·
Locate unit at least 1.5m (5 feet) and route wiring at least 1m
(3 feet) away for fluorescent light fittings as electrical
“noise” and/or flickering may affect the unit.
·
In excessively dirty or dusty locations where contamination
build-up could slow down response.
4. Installing your Heat Alarm
(a) Attaching to Ceiling .
(NB: for wiring the interconnect see page 7)
The Heat Alarm is battery operated. Use figure 3, as a help in
mounting.

Recommended Locations for Interconnected Heat Alarms and Smoke Alarms
Heat Alarms
Rooms adjoining or on escape routes - kitchens, garages,
boiler houses etc. where Smoke Alarms are unsuitable. In
-
stall within 5.3m (17 feet) of potential sources of fire.
Smoke Alarms
1. Within 7m (23 feet) of doors to rooms where a fire is likely
to start. Corridors over 15m (46ft) should have more than
one Smoke Alarm.
2. On each storey.
3. Within 3m (10 feet) of bedroom doors - so warning will be
heard.
4. All other rooms where a fire could start (except those with
cooking/car fumes or condensation).
