Hi,
No doubt this has been asked just a few times before, but I’m wondering – on a generic level – where to put PIRs.
I’ve read up a little and people say avoid facing windows, avoid drafts, avoid above radiators, avoid facing radiators, etc. That seems to discount almost all options in my eyes.
Imagine a square room with a window on one side and a radiator on any of the other three sides. Two corners will have the window in sight, and all four corners are either going to be facing the radiator or be “above” it almost.
Or is all this rubbish nowadays. Does it matter if a PIR is on the same wall as a radiator but is 1+ metre to the side of it (and obviously 1-2 metres above it)?
The attached picture is a lovely little rendering of the ground floor of my house It’s south-facing and has a horrible open-plan layout with rads on most walls and a ground floor extension where the patio doors are. The one window is from wall to wall almost. The sun pours in during the summer. The red patches are radiators.
Where would you place the PIRs by looking purely at this? I have three at my disposal. I thought of maybe having to have two trigger to set the alarm off if the PIRs will be compromised by the layout? There will be a contact on the front door. I know I should have contacts at the back but I've yet to save up for these (it's wireless texecomm premier elite richocet). I'm going wired upstairs but wireless downstairs.
Thanks in advance, and please bear with me!
