(i) A Heat Alarm should only be used in a room adjoining an escape route, in conjunction with Smoke
or Multi-Sensor Fire Alarms on the escape routes. All the Alarms should be interconnected to
ensure the early warning will be heard.
(ii) Some Fire authorities (concerned with the slow response of Heat Alarms) advise that Smoke
or Multi-Sensor Fire Alarms should be fitted in living rooms. This is acceptable according to
IS3218:2019 provided there are clearly not going to be problems with nuisance alarms. Fit Heat
Alarms only if nuisance alarms are very likely and it is acceptable that a warning will only be given
by the Heat Alarm when there is a very significant flaming fire in the room. If the door(s) and
windows are not closed to contain the fire and heat, it is extremely unlikely that the Heat Alarm
would respond before a Smoke or Multi-Sensor Fire Fire Alarm sited outside in the corridor.
(iii) In enclosed kitchens with doors closed.
