morning Mr Happy,
Did as you advised and panel still not behaving.
Linked out bell box (had to invoke the strobe to disable self activate first of all, to stop box sounding) and then linked out all zones, including tamper. Also linked tamper on remote keypad circuit as there isn't any, as intention was to just use panel keypad (compact model)
Also, not sure if related, but 0 on the panel does not respond either.
I've currently powered everything off and put battery jumper to off position in bell box. Whilst at box I double checked wiring and all in correct sequence and tamper microswitch definitely clicking as it should......any further thoughts .... faulty panel ???
Many thanks in advance.
