Chris A Posted September 25, 2016 Share Posted September 25, 2016 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.

PeterJames Posted September 25, 2016 Share Posted September 25, 2016 Was there any signs of a spider? Cobewebs? Spider close by?

Chris A Posted September 25, 2016 Author Share Posted September 25, 2016 Thanks for all the interest/feedback so far. I had heard that spiders could cause issues but jut wasn't sure if they could cause the alarm/restore/alarm/restore pattern shown in the log. 2 hours ago, Nova-Security said: http://spiderex.co.uk/ Didn't know such stuff existed! Will get hold of some asap - prevention won't do any harm.
