Hi
The system is based around a Scantronic PD9651 with four Honeywell IS312 PIRs with fsl wiring. It was installed around four months ago and has been operating properly until now.
Last night a false alarm condition occurred after the system had been fully set for about a week. The relevant part of the log reads:
22.07.06 Burg Z04 Alarm
22.07.09 Burg Z04 Restore
22.10.23 Burg Z04 Alarm
22.10.26 Burg Z04 Restore
22.25.24 Z04 Lock Out
22.25.24 System Rearmed
I have checked the connections inside the PIR and all appear to be good and tight and the resistor legs appear to be sound and not crossed. Nonetheless, I have given the screws an extra tweak.
Very close to the PIR I did, however, find quite a large spider. Could it have been the cause of this particular false alarm? If not, as usual, any suggestions/comments would be most welcome.
Many thanks.
