    Adding new Honeywell IS312 PIR to Galaxy 20 Panel

    Hi All - Does anyone know if I can add a PIR to an existing zone that has one PIR on it. If so with the pir wired as in the picture where do I attach the wires on the panel ideally I want to use zone 3 or 4. I'm not sure if the original wiring is using same colours as I have for PIR. Many thanks
