5. If the mains wires are recessed (coming
through a hole in the ceiling), bring the wires
to the terminal block through the rear hole in
the mounting plate as shown in figure 3.
Ensure the rear gasket seals around the
edge of the hole in the ceiling. This is to
prevent air draughts affecting the smoke or
heat entering the alarm. If the orifice is too
large it should be sealed with silicone rubber
or equivalent (when the rest of the
installation is complete).
If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is as shown in figure 3.
(b) Carefully cut and trim the knockouts in the
RadioLINK
Base side walls to blend
with the contours of the trunking.
Important:
Only cut the thinned down knockout section and leave the top intact as
shown. There is only one position suitable for the surface wiring to enter the alarm.
6. The house wiring must then be connected to the terminal block on the Ei168
RadioLINK
Base as follows (see figure 3):
L
: Live - connect to the house wires coloured brown, red or marked L.
N
: Neutral - connect to the house wires coloured blue, black or marked N.
