Regarding the PIR's facing windows.... NEVER put them to face windows.

If you dont have any other choice (ie. window on every or three of wall's) use dualtechs and try to make the detector then to face the window which less likely takes the sunshine or any other light source (ie. car's, etc..) in.

I definately cant believe it! Once again I agree with Georg, windows are a problem if bright sunlight hits them, if its got to look at a window use something with a white light filter.

Must be my lucky day then.... *going to fill the lottery coupon*

Thanks for your advice about the PIRs guys! Both as to the type of PIRs to get and to their siting.

I have now bought 4 Texecom Reflex PIRs (and 2 more reels of 8-core, which should hopefully see me through).

I've also altered my plans so that the PIRs aren't facing windows (unfortunately this will make some of the cable runs slightly less neat, as the new sites are less able to be chased to, so I'll need to do some pinning of cable to sides of wooden frames etc)

Thanks again for the helpful advice,

Mike

Can`t you get some floorboards up and run the cable underneath to the detectors desired locations..?

I'm doing this quite a bit for most of my cable runs, however the lounge and dining room both have covings, which makes things trickier.

Now this is where you need to know the tricks of the trade.

thats right, Karen Carpenter, AKA long skinny drill bit.

....and i do hope that those tricks of the trade are going to stay that as well guys!

Helping someone site a PIR is one thing, telling that person how to carry out an install correctly, concealing all the cables etc etc in another - don't you agree that you'd be selling your skill and experience far short of what they are worth??

My dad has moved into a new house recently and while installing the alarm system he asked me to change a couple of light switched as well - no problem we can all do this safely. However, when looking at the wiring it was old, sarting to break down and generally not in a very good condition.

So I told him to call an electrcian - not log onto electricalinstaller.co.uk and find out how to complete a reqire of his house - because thats a specialist trade and it requires skill and knowledge gained through training and experience.

This subject of "giving a helping hand" is cropping up more and more - isn't is about time we had a serious debate (in the trade section) about this can came up with some hard and fast rules??

Debate sounds good.. Go and start the topic then.

I will indeed participate !
