Smoke Alarm

[crapmemory]

The other day my smoke alarm beeped for no reason. This has happened a few times so I changed the battery. It still beeps randomly. Any suggestions why? TIA

It's broken ?

Are you sure the battery you tried was ok ? Not a wire broken off somewhere ?

Maybe give it a quick vacuum, might be a bit of dust upsetting it

When this happened to my alarm (VERY loud and scared the bejeezus out of me!)I emailed the company and they said to give it a vacuum with the soft brush attachment. I did that and all's been ok since... fingers crossed.

Reckon if it had a broken wire it wouldn't be making any noise

Is the battery connected the right way? +>+ ->>-

you cant fit the battery the wrong way

Given that your local branch of Screwfix can sell you a new smoke alarm for £5.49 (inc battery) it might be simplest just to replace your existing one:

However do check all your plugs and sockets first. I had a smoke detector that occasionally beeped for no apparent reason. However a bit of hunting around found that I'd got a very hot mains socket which, even though I couldn't smell any smoke, was enough to trigger the device.

It means a new battery is needed.

Depends on the broken wire. I've no idea is the sensor fails the circuit to buzz or silent. But probably worth a vacuum anyway; you never know.

That happened to mine, I struggled to discover what the problem was until I saw the life date on a little label on the backside. It was 2 years over its rated life span. If a new battery and a gentle dust/hoover doesn't sort it, replace it.
