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 trunking
as shown in Figure 6. 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.
