    I'm just in the middle of running the cabling for the alarm, and have found one of the routes is a bit tricky, i've got one bit of cable in (8core) and i'm now wondering if I can run this to the one PIR and then from that PIR to the next? instead of having to run another cable.
    Is this ok?
    The detectors will be dual tech if that makes any difference.

    8 wires >> An example of usage for 2 detectors on same cable

    Red / Black > 12v DC supply to both detectors ( Wired in Parallel )
    Blue / Yellow > Anti tamper at both detectors ( Wired in Series )
    Green / White > Alarm Circuit Detector 1
    Orange / Brown > Alarm Circuit Detector 2

    Colours shown are as an example only
