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...

datadiffusion Posted September 25, 2016 Share Posted September 25, 2016 That's interesting. We have had a 2nd (and only ever with the e-Line DT) FA the other day, there was a large web over, I dismissed this as a cause being it was a Conservatory (which I assumed was the major factor, although, it happened at 3am, hardly primetime for temp changes...) Looking back I should have given it a blast of Spiderex... FA's are so rare since I switched to Siemens (many years ago, started with the IR120) I've almost forgotten what to do!

redsun Posted September 25, 2016 Share Posted September 25, 2016 Spiders would defo cause this and I've used spiderex for a number of years now. It work better inside on pirs but not that good on infrared cameras. This is 3 weeks haha! Quote Link to comment Share on other sites More sharing options...
dufjax Posted September 25, 2016 Share Posted September 25, 2016 I remember we used to use a spider replant in a trigger spray bottle which smelt of Cloves, I'm sure one of the wholesalers stocked it. Not sure if it actually worked? Quote Link to comment Share on other sites More sharing options...

Not sure if it actually worked? Bottles of the clove spray are also available from Lakeland - right beside the cans of SpiderEx. They cost a lot less but SpiderEx seemed to be the way to go judging by the comments here! Many thanks to all who have contributed. I had not realised that spiders could be such a problem. Nonetheless, if a squirt of SpiderEx avoids this issue from returning, then I am happy! Quote Link to comment Share on other sites More sharing options...
Jim Randle Posted September 26, 2016 Share Posted September 26, 2016 We used Raid fly spray in the past but were told (by Visonic) that the propellant in the aerosol damages ABS plastic. We had loads of cases cracking up. Jim Quote Link to comment Share on other sites More sharing options...
