Tommygunn Posted September 13, 2012 Posted September 13, 2012 I'm looking to place a couple of standard PIR's within my below ground garage space to cover all possible points of entry, however, I need some advice as to the placement, taklng into account the various entry points and other factors. Below I have pieced together a montage of the garage space. There is a main garage door and a window next to it, two windows at the rear of the garage, a back room and window (out of shot) and the door up to the house at the centre right. Other factors that may effect things are that the garage door, and immediately above it, are ventilated via louvres and mesh. The two windows at the rear, plus the back-room window are sometimes left open (low risk - below ground with metal grill above). Any recommedations on how to cover all these points with two PIR's and whether there will be problems with breeze (very little), spiders etc etc. Many thanks, Tom.

Lwillis Posted September 13, 2012 Posted September 13, 2012 If your worried about breeze problems fit dual techs . Will help reduce false alarms
Oxo Posted September 13, 2012 Posted September 13, 2012 H/D Contact on the door and a DT. Or a nice 360 away from tha nice light fitting.

norman Posted September 13, 2012 Posted September 13, 2012 I wouldn't put a PIR or DT in there with the door as it is, contact on the door and window. Nothing is foolproof to a sufficiently talented fool.
Oxo Posted September 13, 2012 Posted September 13, 2012 It can be fitted as above, masked from the door. Or a curtain passive across the door and a DT in the corner looking towards rear. With the Shutter contact of course.
sixwheeledbeast Posted September 13, 2012 Posted September 13, 2012 ... contact on the door and window. There appears to be multiple windows, no idea if they open to outside. I see no reason why a DT facing away from the door is a problem if the door is protected via a contact.
MrHappy Posted September 13, 2012 Posted September 13, 2012 I wouldn't put a PIR or DT in there with the door as it is, contact on the door and window. Ding! The LHD punto, the loured door, the grill above the head of the garage door & the foreign electrics all point to somewhere sunnier than Barnsley I suspect the extremes of temperature & white light bouncing all the shop will be a touch too hostile for even a DT Mr Veritas God
