Guest sp1bob Posted September 21, 2006 Share Posted September 21, 2006 I have had some cabled installed whilst I was having and extension built and am now at the stage of fitting the control panel, PIRs etc. Unfortunately some of the PIRs will have sight of windows (although not direct sunlight), is this going to be an issue for me and if you why and how can I get round the problem ? Incidentally none of the windows have curtains. Ta Link to comment https://www.thesecurityinstaller.co.uk/community/topic/12654-pir-positioning/ Share on other sites More sharing options...
ian.cant Posted September 21, 2006 Share Posted September 21, 2006 You cant get round it unless you relocate the cable to a different position. It may/may not cause any problem your going to have to suck it and see!

Guest rjbsec Posted September 21, 2006 Share Posted September 21, 2006 Dual-technology detector - normally PIR and microwave. However the PIR can still be compromised by say sunlight across glass but with the addition of the microwave technology it shouldn't cause an alarm.

Guest sp1bob Posted September 21, 2006 Share Posted September 21, 2006 Ah right, got you. I'm using Texecom Prestige QD Quad Element PIRs - gues I'll just have to give them a go as moving the cables isn't really an option ( Link to comment https://www.thesecurityinstaller.co.uk/community/topic/12654-pir-positioning/#findComment-121442 Share on other sites More sharing options...

Guest sp1bob Posted September 21, 2006 Share Posted September 21, 2006 Whilst you are all in such a great mood, I realise I can't run alarm cables parallel with mains cables, but can I cross over mains cables at say 90 degrees without having any problems. Thanks again (hangs his head in shame) Link to comment https://www.thesecurityinstaller.co.uk/community/topic/12654-pir-positioning/#findComment-121452 Share on other sites More sharing options...
Guest rjbsec Posted September 21, 2006 Share Posted September 21, 2006 Shouldn't cause a problem if it's few and far between. Link to comment https://www.thesecurityinstaller.co.uk/community/topic/12654-pir-positioning/#findComment-121456 Share on other sites More sharing options...
