Having spent ages checking everything i have come to the conclusion that the pcb must be faulty.

 

Obviously this alarm is discontinued so can anybody recommend a suitable replacement for this alarm?

 

It has 15 id-plus zones with one remote keypad.

 

To keep work to a minimum i would just like to replace the panel and rkp if at all possible.

If tour going to do that , loop everything off, just to check pcb is still showing fault, ie disconnect all except keypad loop all tampers and default it and then probably pcb

its iD

castle do a euro 16x (not sure on the final digit that will do iD
