I understand graded sensors have eol jumpers & jb's have tact switches due to wiring faults ?
Personally I found adding resistors or leaf tampers worked for 10yrs + before EN
still not tried it on webway, however the longer I hang on it the more little the shite pile grows
I currently have-
ade accenta
9448
battery pifco thing
m800
odd c&k thing (800 onboard)
some veritas tat
a metal twin flex
a plaggy c-tec
I will send up to 10kg on landfill ? c/w your I-on
some sort of panic prob ?
either a button on a circuit or something to do with key 1+3 ?
check wiring, power cycle, default reprogram
or rip it off the wall & stamp on it....
