3. Recommended Locations Of Alarms
This heat alarm must only be wired to a 240V AC 50Hz sine wave current supply.
Heat alarms give an audible warning when the temperature at the alarm reaches 57°C.
Heat alarms are 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. Laws on heat alarms vary from state to state and you should be
aware of what the requirements are in the state you live - for more information please refer
to your local fire emergency services. PSA recommends heat alarms be installed in addition to
legislated smoke alarms in areas where there might be high air circulation or in areas such as
kitchens, bathrooms or garages where smoke alarms would be subject to higher false alarms.
If, however, the design of the dwelling does not comply with modern fire safety standards, or
if factors such as the presence of several young children, elderly occupants or disabled people,
or smokers, the use of portable heaters or solid fuel fires during the night, or the use of electric
blankets, particularly by the elderly, PSA advises that additional detection devices, installed
within rooms, may be necessary.
The most favourable mounting location for a heat alarm is on the ceiling and in the centre of
the room. At this location, the alarm is closest to all areas of the room. EXCEPTION: When the
mounting surface might become considerably warmer or cooler than the room, such as a poorly
insulated ceiling, below an unfinished attic, or an exterior wall. In these cases the alarm should
be mounted on an inside wall.
•
If the alarm cannot be located
in the centre of the room, an
off-centre location can be used
on the ceiling. When off-centre
mounting an alarm on the ceiling,
locate it at a minimum of 300mm
from the side wall (
