The Smoke Alarm From Hell.

Goes without saying that it is at the most awkward time possible ( usually 5amish ) that the smoke alarm starts beeping. ( Three consecutive beeps repeated approx. once a minute for hours ).

Electrician says he can't fix it because legally it is the business of the fire brigade.

But what is the problem in the first place ?

There are several smoke alarms in this house but the only one that signals its presence is the one in my own bedroom ( obviously ).

I am unaware of any source of smoke in the building( which does not have a coal fire in particular ).

Could it simply be that the room is 'stuffy' and an open window would literally clear things up ?

It's definitely smoke rather than CO alarm I take it?

Low battery?

I would say that sounds like low battery, but you mention an electrician which suggests it's wired in.

Bollocks is it the business of the fire brigade. This is in your own home?

Replace it. If you aren't confident about wiring it in, get a different electrician.

Electrician is nuts. Replace it. What brand and model?

The alarm could be wired in and have a backup battery. My home security system is set up that way.

If the backup carks it the system whines to let me know.

We have one with a battery in the unit (eg when it goes you have the replace the whole thing). One day last month it emitted three loud beeps every hour or so.

We tested the battery, which was fine. We searched high and low for any sign of fire or other issues and found none.

In the end I googled the issue and it was suggested we give it a good hoover, which we did and that stopped the problem.

Backup battery, yep.

Literally ? Or do you mean just brush around it ?

My smoke alarms are wired and have a backup 9V battery, this does need to be replaced every umpty years, and we get informed of this by annoying intermittent beeps.

Or you could just hoover it, that seems less hassle.

If you have a battery-only smoke alarm, it will probably say "use Duracell battery only". This is at least partially true. It needs a premium battery, rather than a pound-shop job, if you want to stop the chirps.

As somebody else said, apply the nozzle of a vacuum cleaner to the vents. Dust inside can cause false signals although intermittent chirps is more likely a nearly dead battery.

It's bewitched. Take it down and burn it.

FredDee - 15 Nov 2021 16:10:09 (#14 of 50)

if it was a question of low battery would not any signal to that effect be continuous ?

What I did not mention was that the beping seems to occur on random days

rather than every day.

You're not allowed more questions until you've followed the advice!

They have a malign intelligence and only beep at the most annoying times possible. Our last one was around four in the morning. It was timed exactly to jolt me back when I thought it was safe to ignore it until morning.

What you've got there, is a wanking detector.

fogsake - 15 Nov 2021 16:16:57 (#18 of 50)

No no. They are wank disruptors.

darkhorse - 15 Nov 2021 16:17:55 (#19 of 50)

It's not been hit by a ricochet, has it?

Kucinghitam - 15 Nov 2021 16:20:38 (#20 of 50)

Nah. Every smoke alarm I've ever met starts out with unpredictable intermittent chirps as though designed to drive you mad.

"Wake up! Did you hear that?"

"Zzz. Hear what?"








"Wake up! There it is again!"




"OK, so now that it's morning, WHICH bastard smoke alarm was it?"
