The other day, whilst at home and the system unset, the speaker sounder went off (but not the SAB). I entered the engineers code (didn't try a user code first) and the alarm stopped. I've not had any false alarms whilst the system was set. Not had any problems since. It seems this was a one off.
The log reports "K01 missing" and "K01 restore". The wiring to the keypad is fine although it does pass near the consumer unit and had already been relocated by previous owners by a local company after false alarms (reason for those not in report). Their recommendation was to use screened cable to the keypad if the "false alarm" continued.
Is the 9943 prox keypad prone to these errors? Anything to look for?
