Pir Positioning

[Guest sp1bob]

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.

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!

What's a dt ?

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.

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 (

Thats more than good enough for us, we usually manage to upset some as they ldont ike the answers even though its good advice so a thanks is sort of rare and appreciated!

You're welcome ..........

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

Shouldn't cause a problem if it's few and far between.
