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. Quote Link to comment Share on other sites More sharing options...

PeterJames Posted September 25, 2016 Share Posted September 25, 2016 Was there any signs of a spider? Cobewebs? Spider close by? Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
