Accenta Alarm Help
First timer.....
My mate cut through a pir cable and when he joined it none of his pirs are working now.
I tested all the glass fuses and mains fuse but the pirs are not lighting up.although the led panel is but not setting.
Ive been a spark for 24years but this isnt my field.
Any ideas?????
Thanks

I assume you took the fuses out and metered them.
Did he wire back colour for colour?
Not setting means the circuits (PIRs) ore showing open, which means lack of power.

Could be the PCB went as well as the fuses.
