HEAT ALARM LOCATION
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.
Guidance on fire detection in dwellings is contained in BS 5839: Part 6.
For normal-sized bungalows, two-story houses, flats and maisonettes, the
British Standard recommends that the minimum level of protection should
comprise smoke alarms in the hallways and staircases. This minimum
standard necessitates one smoke alarm in the hallway of a typical bunga-
low or one smoke alarm on each level of a two-story house. Heat alarms
should not be used in these circulation areas. If there are, for example,
long hallways, even the minimum standard may necessitate additional
interconnected smoke 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, of elderly occupants or disabled people, or of smokers, the use
of portable heaters or solid fuel fires during the night, or the use of elec-
tric blankets, particularly by the elderly, the British Standard advises that
additional detection devices, installed within rooms, may be necessary.
The British Standard recommends that, if the risk justifies the provision of
detectors in a kitchen, boiler room, or other area (except a circulation area)
in which smoke alarms would be likely to give false alarms, heat alarms
should be used. However, the Standard also advises that heat alarms
may be installed in other rooms instead of smoke alarms, provided that
the construction enclosing the room (including the door) can resist fire
for a sufficient time after operation of a heat alarm to enable occupants
to escape safely. However, a heat alarm is unlikely to operate early enough
to save the life of anyone asleep in the room in which it is installed.
Moreover, a heat alarm in the room of fire origin may not give sufficient
warning for occupants to escape safely if the door to that room is open.
