My external sounder went of in the bad weather - turns out some tracks on the circuit board had corroded - anyway I hard wired some connections and it is now operational again - my question :- Can I replace just the PCB as strobe & bell works fine ??
if the alarm is now working fine then give it say a weeks trial and if it fails again then if its the bell box that causing the fault then it needs changing try and get the same model for easier install , death
