Wolfie Posted July 20, 2018 Share Posted July 20, 2018 Anyone know why my wired smoke alarms should go off?. I don't mean chirping because of a low battery, I mean full alarm for maybe 10 seconds and then stop. Thing is, it did it at 4.30am, 5am and 5.30 this morning.....and then not again since. Why so regular but only 3 times? I'm pretty sure the downstairs one went off first and then the upstairs one joined in. ?? Link to comment Share on other sites More sharing options...

AndyinLiverpool Posted July 20, 2018 Share Posted July 20, 2018 In a previous incarnation, I was in the fire service. Sometimes (and usually at night) got called out to fire alarms set off by insects crawling into the detectors. Could be that. Could also be a power surge or whatever the opposite of one of those is.

McRamFan Posted July 20, 2018 Share Posted July 20, 2018 How old is it? When did you last take it off and clean it? Link to comment Share on other sites More sharing options...

We've lived there for 4 years but I don't know when they were fitted. The same model is still on sale but that might not be a good indicator. Yeah I'll give them a clean later (I have vacuumed them occasionally) but it's the weird 30 minute interval thing that I can't get my head round.

Take the unit off and the 9v battery out, if applicable, leave outside, in the shade for a few hours, get a new battery if its older than a year (battery that is).

A Ram for All Seasons Posted July 20, 2018 Share Posted July 20, 2018 Are they battery powered or connected to the mains? Is there anything connected to same circuit that could cut in and out every so often and cause the power to surge, like a fridge freezer or an immersion heater? They are very sensitive to changes in current. Other than that, I'm just as clueless as you are. Link to comment Share on other sites More sharing options...
