Installation

WARNING: First disconnect the mains from the circuit to be used.

1.Choose a mounting position following the siting instructions in the Smoke/Heat Alarm leaflet. Where the incoming wiring is on the surface of the ceiling, the appropriately sized ducting/conduit must be chosen to mate with the unit. Use a sharp knife to remove material from the selected knockout, making sure that there is no gap when mated with ducting / con- duit. There are three knockouts – two on the sidewall and one on the rear.
