Installation

Installation procedure
1 Select a location complying with the advice in the
Location and positioning section.
2 Remove the mounting plate from the smoke alarm
by twisting it in an anti-clockwise direction, see
Figure 5.
3 Place the mounting plate on the ceiling exactly
where you want to mount the smoke alarm. With
a pencil, mark the location of the two screw holes.
4 Taking care to avoid any electrical wiring in the
ceiling, drill holes using a 5.0 mm (3/16") drill bit
through the centre of the marked locations. Push
the plastic screw anchors provided into the drilled
holes. Screw the mounting plate to the ceiling.
5 Connect the battery to the battery snaps. Verify
that the red and green LEDs on the cover alumi-
nate as indicated in the table on the Indication
summary on page 5.
6 Place the smoke alarm unit on top of the baseplate
and twist it clockwise to attach it. Install all the
other alarms similarly.

Rotate the unit anti-clockwise.
If the unit doesn't come off, it may
be tamperproofed - see fig. 7a-7d
7 Press the test button on each smoke alarm to ensure that
the smoke alarm unit works, see Figure 6.
Tamper proofing the smoke alarms
The smoke alarm can be made tamperproof to prevent
unauthorized removal of the unit. Proceed as follows:
Break off the small pillar on the base as shown in Figure
7a. To remove the smoke alarm from the ceiling it is now
necessary to use a small screwdriver, to release the catch
(push catch towards the ceiling) and then twist off the smoke
alarm, see Figure 7b.
If necessary, it is possible to further secure the smoke alarm
by using a No.2 or No.4 (2 to 3mm (1/8") diameter - not
supplied) self-tapping screw 6 to 8mm (1/4") long, see Figure
7d, to firmly lock the smoke alarm and its mounting plate
together, see Figure 7c.
