Have an (ex-ADT) Honeywell Galaxy 2-12 with CO12 'box'. It has been giving me "bat mis +0001" messages once every few days.
I have read this means the internal 12V battery is on it's last legs.
Went in engineer mode, I opened the box. Carefully avoiding pulling on other wires too much I rotated the battery to read what it was rated at. The action of moving it immediately caused the all the power the my house to turn off, and the outside alarm to sound (rather weakly). 5 seconds later it went back to normal.
Very odd. Anyway I bought a new battery and installed it in place of the old one. Closed up, exited engineer mode. All happy so far.
Few hours later, power to whole house flicks off and immediately on again a second later. Suspecting something may be loose in there, I take a (non conducting) pen and poke all the cables and connections to see if I can make it repeat the behaviour. Nothing happens.
So this is making me wonder if there is, in fact, a problem with a component that is gradually deteriorating and developing a tiny earth fault. Maybe the transformer? Any suspect parts in there that are known to cause this? Could the deterioration of any part also make the battery not change up correctly or otherwise produce the 'bat mis' warning at random intervals?
I'd like to get a handle on what it might be. If not too expensive I'd probably going to get someone out to repair it, but I am also considering just having a new alarm fitted. Probably will power it all off for the time being while I think about it.
Incidentally, does anyone know how to isolate this thing? I only have a direct cable from the consumer unit (no switch) to an unswitched fused spur, and then to the main alarm box.
Cheers
