HKC Open tamper fault

Thanks a mil - when you say looping out - you mean opening up each window sensor one by one, and………..

(1) If its a sensor mid-circuit, join red to red and black to black.

(2) If its the end of the loop, join red to black

I think this is how you take the sensor out of consideration, and the system thinks all is OK?

Well, it was working perfectly, and now this one fault has popped up. If it can be investigated with some straightforward steps and its able to activate again, why wouldn't I give it a go

I gave that a go, pulling out the middle 2 wires from the 6 ports on each sensor, tying them together, and the fault didn't clear. Potentially a damaged wire along the way? If the tamper circuit is just to detect when a sensor cap is taken off, I'm not too bothered if thats not working. Could I just go to the main system panel, and for that zone that's giving the tamper error, just do a small bridge across where the blue and yellow are going in, fooling the system into thinking all is ok on the tamper circuit?.... You can see cable for each zone here, I'm just going to take out yellow and blue and do a all wore between the ports, that ok?.....
