I think i worded that wrong lol, with them joined together in the kitchen do u get continuity on the cable from the panel to the hall? U can actually wire each detector with 3 cores if u link 0v and com in the detector, then wire the other core to eol terminal on the panel
Hey. Yes, if blue and yellow are joined at both PIR locations, there is continuity all the way back to the panel. Reading 3ohms.
Per your wiring diagram below, I think I can probably try and and execute that, thank you. I am a bit confused about what's going on with this blue / yellow pair now... why do they need to be twisted together in both PIR locations to get continuity back to panel? No com wire required - is that because you've looped through 0v?
As above it may have been junction boxed in series under the floor …twist together at both pirs ( blue and yellow ) then check at the panel end …
Yes, you've got it. I don't really understand what is going on though? 3 ohms at panel when blue and yellow twisted together at BOTH Pirs. But if either twist join is removed at either PIR, nothing back to alarm panel? I thought ok, so the feed is direct to kitchen rather than hall but why both need to be twisted together to get a reading...
Thanks both, you've really gone out of your way so far. I thought this would be a pretty easy change over. Which I suppose it has been but this pre-existing issue has side tracked me!!
I've also installed a new delta bell - X and light box. The one on the front of the house was fully operational, but made it look quite unkept and out of date. It's a metal enclosure with a W on the clear PCB cover..... I'll post a photo just for nostalgia.... On the new delat bell x - I am still getting a tamper fault after completing install. Its not the front cover tamper switch. Is there a back tamper switch? It's raining now and I don't want to be climbing ladders until it's a little drier and I know what I am actually looking for!!
I assume this wiring diagram posted is correct? And the -12v needs the jumper onto one of the T terminals.. That's what I've done. I don't recall seeing the back tamper switch in the new delta x unit!!
Thanks so much...
