    Hi all,

    I am decommissioning a Chubb CA67 and replacing it with a Yale Wireless system. I am trying to identify the pair of wires the phone is connected to.

    Can anybody point me to the correct pair ?

    The system has two boards, a larger one which I think is connected to the sensors and the speaker, and another behind this which has far fewer connections. There is a pair on the far right of this which looks promising although I can't detect any voltage across them (but maybe this is because the system has not worked properly for years as apparently some builder put a bunch of nails though quite a few of the sensor wires).

    Any advice gratefully received.
