Mains smoke alarms - cheep every few days
Every few days (I think) one or both of the mains smoke alarms cheep once.
On line search suggests that low battery should cause a regular cheep (already experienced that and changed the battery). There is also a suggestion that dust could cause a false alarm - but this isn't an alarm, just a single cheep. Has anyone else experienced this, and worked out what was causing it? The alarms have been fitted for about 5 years. Oh, and does everyone change their smoke alarms every 10 years?

A bit of reaearch suggests its not a low battery, but it could be dust, or a failing sensor. I had a long shower with the bathroom door open earlier this year. The bloody lot went off...

Ours have produced single, random cheeps as the batteries have got low, only progressing to regular cheeps as the battery deteriorated (it was about a week until we got the time to get new batteries and fit them). We also had a similar effect with a microchip cat-flap - when it took us days to find the problem, as the sound was very low volume and difficult to locate, sounding like it was in another room, no matter which room we were in. The alarms have been fitted for about 5 years. Oh, and does everyone change their smoke alarms every 10 years? Not here. The recommendation seems to have come about because some alarms are fitted with 10-year batteries and because sensitivity can change (it usually increases), causing nuisance alarms and prompting people to disconnect the batteries! As long as ours continue to keep quiet unless the toast has been burned again, I'll trust the test function and not replace them. SteveW |

As we have no idea of the make and model number of the detectors all we can do is guess. Do 'mains smoke alarms' have batteries? Good question. Grade D is the minimum requirement these days for interlinked smokes in a new build. These do require some sort of standby back up should the mains fail. This could be in the form of inbuilt capacitors and may not a battery. Grade E detection systems are mains powered without any form of battery back up. They are frowned upon and possibly illegal to fit even though they may be interlinked. Grade F are battery operated non interlinked detectors. These are the minimum requirement for all rented properties in England. -- Adam |

A bit of reaearch suggests its not a low battery, but it could be dust, or a failing sensor. With a bit of research, on some main powered and battery backed up detectors multiple beeping every 40 seconds (rather than once every 40 seconds for low battery) is an end of life indication. Also if the replacement battery was a rechargeable type the detector may beep during the first few days until fully charged. With my battery alarms I often get the first signs of a low battery a few times at night when its colder but by morning when perhaps the heating comes on the battery recovers a bit and the beeping stops. I now put a label on the units giving the date when the battery was changed. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Last year they all started to do a once-a-day cheep. It turned out that the one in the loft had a faulty battery. Bill |

Combination of low battery and low temperature usually. Typically they cheep sometime during the night when your just half aware of it. When the temperature rises during the day they cease cheeping as the battery voltage rises above the alert threshold. Then you forget all about it until the next cold night. ;-) Tim -- Please don't feed the trolls |
