Yes, apart from the two faulty heads. These heads don’t work on other bases and the working heads work on these two bases too.So all detectors now have the green indicator illuminated.
When I tested these earlier today, I removed all the heads and then fitted the first one (where the mains power was supplied). I then fitted what I think is the next one in the chain. I then tested, they only beeped individually. I then added the next one and tested as I went along. Each time, there were no multiple alarms beeping.Test each alarm in turn, if two sound then they are interconnected, then do the same with one of those and the next one, when you get to one that does not sound with the previously sounding others then the interconnect between it and the others is suspect, this way you could narrow it down to one of two legs, test between each cable at the alarm for shorting, a continuity tester and a long lead would make it easier between alarms.
Another but messy check is to temporarily disconnect each alarm from the existing interconnect cable and then connect each alarm with some 0.75 multi stand, cheap and easily obtainable.
Or disconnect the interconnect from all the alarms and put in the radio base's probably easier in the long run.
I’ve tried it with and without he faulty detectors. Not had any effect.I was about to suggest is it being tried with the faulty detectors not in place.
But would every leg of the interconnect short as none of them are working?Rather than a continuity problem, it's more likely to be that the interconnect wire is shorted out, either by a wiring fault or a faulty detector.
I couldn’t test from the call point as I don’t have a key.Does the call point work?
Are you testing from the same sender unit each time? if so test from a different sender unit.
Do these alarms work individually?
If none of the above work, I would suggest making up a test panel removing the alarms and base's and testing on that you could then eliminate the rogue element of the interlinks in the alarms being the malfunction.
Yes, power at every base.Is there power at each base?
Is there two x 3 cores at each base?
I’m thinking, if you test at various bases, and there’s no interlinking… maybe there’s a central jointbox and the interlink cable is loose?
I see the first photo they used the wrong colour for the neutral (no discussion… it’s just wrong!?)
Is that the same all the way through?
Neutral and interlink mixed up can cause damage.
They are horribly fiddly aren't they!If you an get three x 3&E cable connected and fully enclosed within the terminal box of an Aico smoke alarm base, then you have my respect!
My long nose pliers are magic!They are horribly fiddly aren't they!
