We strongly recommend that you check for the following before connecting the alarm:
• check for Live and Neutral using a two probe tester.
• check for Live using a neon tester.
• check that the Interconnect is NOT connected to Live, Neutral or Earth. Do not connect an Earth wire
to the Interconnect.
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 & yellow, can be
safely terminated.
4. Lift off the wiring cover as shown in Figure 5 overleaf.
5. If the mains wires are being brought along the surface, conduit can be inserted into the top and/or
bottom of the mounting plate.
(a) position the mounting plate, so that the cable conduit is as shown in Figure 5 overleaf.
(b) Carefully cut around the knockout on the outside wall so the conduit fits. (Note: to comply with the EN
60529, IPX2D protection rating, seal around conduit with silicone rubber or similar to prevent water entering).
6. If the mains wiring is recessed, bring the wiring through the rear hole in the mounting plate as shown
in Figure 6.
7. 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 CO gas entering the Alarm. If the hole is not closed off by the gasket
it should be sealed with silicone rubber or equivalent.
Note: House wiring should not be "bunched up" in the area of the Alarm but quickly and neatly directed
away. This will minimize their effect on the radio antenna.
8. Replace the wiring cover.
9. Carefully line up the unit on the base and slide on.
