easy pir

mazfari · 25 Aug 2010

hi guys, had an attempted break in last night, got an optima xl4 alarm fitted with 4 zones, works really well and saved the day last night. I need to wire a pir into the garage but all zones are in use, can i just use 2 pirs in one zone, using 2 seperate cables, not sure how to link them so was just looking for the easiest way one wire to one, one wire to the other.

thanks guys

Its not recommended but yes you can have 2 pirs on one zone it wont do any harm. You can either run a cable from the control unit or the other pir. The power is wired in parallel and the alarm loops in series. There should be posts on this site on how to wire in series etc.

Hope this is of some help

Thanks Grahame, to get a cable to the other pir(in Living Room) would be a nightmare, however to put the new pir in the garage would be a case of drilling thru the back of the control unit box as the garage is on the other side of the wall. is there an easy way,

Thanx for your heSteve

That should be Ok as there are usually knock-outs at the back of the panel. Power in parallel and alarm and tamper loops in series, back at the panel end. That would be the easiest way if you can't get a cable to the living room
