Heat Alarms EIB603CX are supplementary to Smoke Alarms and must be
interconnected to the Smoke Alarms EIB650iWX 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.
Locating your Smoke Alarm
The following two examples can be used as a guide line for locating your Smoke /
Heat Alarms to obtain the highest possible sound.
Multi-Storey Dwellings
If your home has more than one storey, at least one Alarm should be fitted on each
level (see Figure 1). The units will be hard-wired interconnected so as to give sufficient
warning throughout the property.
Figure 1 illustrates where Heat Alarms and Smoke Alarms should be located in a
typical two storey house. Note the spacings in “Protection Levels” as given in Figure 1
& 2 which ensure the early detection of fire and that the warning will be heard.
