Why is my fire alarm going off?

    Was out for a few hours this afternoon. Came home and the smoke detectors are beeping.

    No fire, no smoke, no real reason for them to go off due to CO.

    It's a two story twin home. I disconnected the smoke detector on the upper floor and it seems quite so far. Could it just be a bad smoke detector?

    There's an alarm system and the smoke detectors are connected to it but it is not monitored.

    They will go bad - after so many years. I had to replace one a month or so ago.

    Dust will make them go off too. Most (all?) work with a photo-electric cell. Smoke breaks the 'connection' and the alarm sounds. If dust gets in there to block the 'sight' of the cell, they will sound.

    I test mine twice each year. And, I remove them and clean them with my vacuum.

    Good luck! :wavey:

    The house is less ten two years old. I'll clean it and hope for the best.

    It's the ether from that invisible time portal that metamorphosized on your bedroom wall.

    Get some chalk and map it out.

    Check the kid's room for your daughter and the dog.

    Like its mentioned above, change the battery. Every chirper we have run across has had a weak battery.

    Well, I pulled it out. It was clean. Blew on it anyways. Seemed to work fine for another hour or so then started beeping for no reason again.

    The good thing is they have a 7 year warranty. I'll call them Monday.

    But it doesn't give a low battery warning. It is beeping as if there is smoke.

    I will, however, get a new battery tomorrow.

    Another weird thing is only 2 of the smoke detectors will sound the alarm. There are 2 more upstairs that won't.

    They might be on a different circuit if hard wired, or they might still be good. The way a smoke detector works is it uses a beam to detect particulate matter. IIRC the beam is from a radioactive material, so when the half life is up the beam becomes too weak to register on the cell which is when it alarms and you need to replace it. We had it happen many years ago, at 3am. Called the fire department to be sure(thermal imaging cameras for the win, too many nooks and crannies we couldn't see in and if it was electrical it would be impossible to find). After they didnt find anything they checked the detectors and they needed to be replaced. They have a life of 5-10 years.

    I've had a small insect get in there and cause one to go off.

    Mine work on a radioactive substance that emit low level radiation, that is blocked by smoke and a variety of other substances. There is a counter in the detector, and if the counter counts down without another 'signal' capture the alarm goes off. As the system ages, the radioactive element (I used to know what it was) goes through to many half life's and there is no 'signal' from it and the detectors start going off. If the detectors are the wired in models, they all will be tied together with a signal so if one goes off, they all will

    A Carbon Monoxide detector? If so, GTFO and dial 911.

    Change battery and observe for change.

    Mine goes off cause it is near the bathroom door. I take a shower, it gets steamy in there, I open the door and bam, the alarm goes off.
