    i've recently bought a securit 802 control panel + pir's,door contants etc.I was connecting in all at the weekend,but i'm not sure on the connections to the pir's,i understand the tamper and power connections but am a little confused with the two other terminals,one is 'c' the other is 'nc' can anyone advise please?

    cheers.

    Can't help much but 'c' & 'nc' usually stand for "common" and "Normally Closed" contacts on a switch or relay etc so maybe refer to the switch output from the PIR

    Common / Normally closed is your alarm circuit these would wired back to any zone of your choice.
