Fitting Mains Smoke Detectors

The point I was making was that it seemed pointless to have mains powered detectors if you had to have a battery as well.

It is not pointless.

The OP has mains operated smoke detectors
They will be interlinked, so when one goes off, all the others in the house are set off.
If at any time there is a break in the power supply, such as a power cut in the middle of the night when the OP is sleeping, the batteries (one in EACH detector) will be there as a back up so that the alarms still sound.

This is totally different to one cheap battery operated alarm, & each one is not that much more expensive
I have some of these & these

OP- check all your alarms. It may be time to replace them all. The ones I have all say they need replacing every 5 years.

One of the main safety features is the fact that if you are one of those people who take the battery out due to false alarms or whatever then if it's mains connected then at least you can still be alerted of a fire.

Unless, like was said, the fire starts in the fuse box, then if you have no battery either you are bugg3red!!!

As an aside, B&Q have carbon monoxide testers made by Kidde for a tenner at the mo. They are in front of the tills in my store, presume it will be the same everywhere. The best tenner you may ever spend IMO...

Oh yes and to the OP, do check, check and double check that your alarm is free of dust etc, like another poster said - I was plagued with false alarms for ages and didn't realise (after I'd been sanding my bannisters down) that all the dust had accumulated in the alarm and that was what was triggering the falsies.

Why do they always happen at 2am though, making you !!!!!! yourself and jump out of bed screaming!!! :eek:
