Some of the keys on the remote keypad for my Citadel XR2 intruder alarm are getting difficult to use and I don't think the keypads are still available. It's a standard rubber membrane keypad over a PCB; is there any way to repair these? If not, is it a standard interface (marked as
0V, 13V, Comms, Sound, tamper x2) so that other types would work?Dave
