    Hi

    I am installing a Pyronix Euro 46 V10 Hybrid Alarm Panel. I want to use wired ceiling pir detectors with it. Pyronix do a flush mounted one, however I am looking for a recessed ceiling pir detector to install. Does anyone know of any I can use.

    Thanks

    Dave

    Hi Dave, welcome to the forums.

    Theoretically any PIR that has alarm and tamper contacts and runs off 12v.

    I've never done it, but the wiring diagrams are on page 15 of the installation manual.

    Hi SparkyChick

    Thanks for the quick reply. The only recessed pir sensors I have found on the net relate to an occupancy switch for controlling lighting and ventilation.

    Cheers

    Dave

    When I went looking for you last night, fully recessed alarm PIRs do look a bit thin on the ground as all I found were as you say occupancy type sensors.

    I don't do that much with security systems, so maybe one of the guys who knows a bit more will pop along with an answer.

    At a push, you don't really need a Tamper signal. Just a switch to activate the alarm.
    I'll have a look as well...

    Deleted as I'm an idiot and you are looking for a recessed pir and not a flush pir.... Yes, a muppet moment....

    you could maybe use an occupancy sensor to energise a relay (N/C pair of contacts) . you would of course lose the tamper , but could have the cable on tamper loop .

    IMO not everything has to have a tamper wire. A mate was having a problem with a PIR. No feed to it. Somewhere the wire was normally open. I told him we could replace the wire or fudge it. He didn't want to replace the wire so I used one of the tamper wires for the bust feed wire.
    I worked on the principle that if someone had actually got into his house and into that room where the PIR detector was, bypassing the other PIRs, then he's buggered for anyway.
