If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is as shown in
Figure 4
.
(b) the mounting plate has a removable section, take it out to interface directly with
25mm trunking as shown in
Figure 5
. If interfacing to 16mm trunking carefully cut around
the marked section, leaving the top intact and replace the section. (If you are not using
surface wiring, the removable section must be left in place for electrical safety reasons).
There are two other positions which are also suitable for the surface wiring to enter
(and exit) the Alarm, one next to the removable section and another directly opposite.
5.
Carefully align the mounting plate and screw into place. Connect the wires to the
terminal block. With recessed wiring, ensure the rear gasket seals around the edge of
the hole in the ceiling or wall. This is to prevent air draughts affecting the smoke/heat
entering the Alarm. If the hole is too large or the Alarm does not seal it, it should be
sealed with silicone rubber or equivalent.
6.
Replace the wiring cover
& carefully line up the Alarm on the base and slide on.
7.
Press and hold the test/hush button for 10 seconds. The horn will sound. Check that
any interconnected Alarms also sound within this period. With the Multi-Sensor Alarm,
the test button sounds the local horn and on release this horn stops immediately, and
all the interconnected Alarms can then be heard in the distance as they will continue
to sound for a further 3 seconds.
8.
Connect the mains power to the Alarm circuit. Check the green light on the front of
the Alarm is on.
9.
Attach the
‘Smoke Alarm’
identification label provided to the distribution board to
identify the Alarm circuit.
