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 wire is NOT connected to Live, Neutral or Earth. Do not use an Earth wire for the Interconnect line.
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 BS 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.
8.Replace the wiring cover.
9.Carefully line up the unit on the base and slide on.
10.Press the Test/Hush button for 10 seconds. The horn will sound. Check that any interconnected alarms also sound within this period.
