Note: The Alarm does not need to be earthed. However
the terminal marked is provided for the convenience
of the installer so that any copper Earth wire or cable
coloured green and yellow, can be safely terminated.
To interconnect Alarms connect all the IC terminals
together as shown in Figure 7 (see section 2.7 -
Interconnecting Alarms
).
4.
If the mains wires are recessed, bring the wires
through the rear hole in the mounting plate as shown
in Figure 5.
If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is
as shown in Figure 5.
(b) the mounting plate has a removable section, take it
out to interface directly with 25mm conduit as shown
in Figure 6. If interfacing to 16mm conduit 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.
