Your first Smoke Alarm should be located between the sleeping area and the most
likely sources of fire (living room, kitchen for example), but it should not be more
than 7.5 metres from the door to any room where a fire may start and block your
escape from the house.
HEAT ALARMS - Ei603 Series
The Heat Alarm gives a fire warning when the temperature at the Alarm 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 rooms adjoining escape routes, in conjunction with Smoke
Alarms on the escape routes.
All Heat Alarms must be interconnected to the Smoke Alarms to ensure that 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. (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). A Heat Alarm in the closed room will give early warning of fire in that
room and help overcome this problem.
