MrHappy Posted October 8, 2015 Share Posted October 8, 2015 (edited) Great for pushing a milk bottle through a front door of some cnut trying to **** you over. I always thought cavity foaming a porch would be more your style ?

datadiffusion Posted October 9, 2015 Share Posted October 9, 2015 Any good? Yep, ace for PIRs in a corner below the room your in when it's modern glued chipboard T+G, for example. Only downside is ripoff cost of 'plugs'. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39195-how-to-loop-out-a-pir-in-a-system/page/3/#findComment-432134 Share on other sites More sharing options...
sean5302 Posted October 9, 2015 Author Share Posted October 9, 2015 I'm not convinced. There are 6 wires in the cable going to the PIR. At least 4 of them are working fine. My next job today will be to solder the ends of the 2 wires for common and NC, at each end. These are very low voltage feeds, therefore resistance will play a big part. If it works, great. If it doesn't, I now have a 5-zone alarm rather than a 6-zone one. Cutting holes in the floor of a newish house isn't an option. There are no "boards", it's floored with chipboard so exposing small sections of cable isn't going to tell me anything. Thanks for your help, guys.

datadiffusion Posted October 9, 2015 Share Posted October 9, 2015 I'm not convinced. What do you think it might be? You have proven it isn't the panel. I assume the PIR is providing a low resistance when operating? Bearing in mind it will likely still be as high as 30-300 ohms in an older PIR. My next job today will be to solder the ends of the 2 wires for common and NC, at each end. These are very low voltage feeds, therefore resistance will play a big part. Again, it won't be that. Even touching the wires, certainly twisting them, should be enough. Many older PIRs have reed type relays that present a relatively high resistance when closed.

al-yeti Posted October 9, 2015 Share Posted October 9, 2015 (edited) Soldering won't do Jack unless you didn't loop them correctly at PIR end first time Edited October 9, 2015 by datadiffusion Changed pit to PIR Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39195-how-to-loop-out-a-pir-in-a-system/page/3/#findComment-432146 Share on other sites More sharing options...
sean5302 Posted October 10, 2015 Author Share Posted October 10, 2015 It just seems odd that a cable containing 6 separate wires can suddenly lose continuity in 1 or 2 of them, but that is what has happened. I'd have thought a mouse or rat would chew the whole cable but, despite ensuring that the connections are sound at the control box and at the PIR, that's what's happened. It doesn't seem worth trying to replace that zone wiring. A neighbour says the wiring is inside the cavity walls and it's beam and block flooring at ground level, so everything's buried really.
