Installation & Placement
Place the mounting plate on the ceiling/wall and mark the screw holes. Drill
with a suitable drill bit, insert the screw plugs and screw the plate into position.
Simply connect the battery on the alarm and slide into position on the
mounting plate.
The RF alarms should be house coded to prevent possible interference from
neighbouring installations – see instructions for more details.
Alarms should be placed in accordance with the general guidelines shown in
the diagram above. These recommendations are based on the problem of
areas of “dead air” close to corners of rooms and apexes of ceilings, which
could result in the prevention of smoke reaching the smoke detector
House Code Procedure
1. Connect the battery
2. Hold the house code switch
(with a small screwdriver)
until the blue light turns on
and then release
3. Similarly, place other alarms
into house code mode
4. Check that the number of
blue flashes (on each alarm)
corresponds to the number of
alarms in your system
5. Remove all alarms from
house code
6. Button test each alarm to
check your system
