    That usually happens when the unit is no good. I would advise to just replace this for your own safety.

    I agree the unit is bad and needs replaced.

    There should be a date on the back of the detector. They are good for 10 yrs usually. I just had to have my landlord replace one.

    Is it part of a hardwired set of smoke alarms in the house? If so, there is a second battery that is in the main unit only that has to be replaced along with the regular battery. Good luck.

      @Kelley MacKay So very glad you figured it out before you bought a new smoke detector.

    It's bad and needs to be replaced. If it's hard wired, replace all of them otherwise the curling will continue. (Learned this from experience)

    if you don't want the expense call your local fire department and see if you can get a ten year for free

    Had the same problem with three of mine, its the signal that the alarm is worn out.

    As others have mentioned, replace any smoke detector after 10 years. Our local FD says even if the new battery stops the beeps, the smoke sensor nearly always has a 10 year life. Old ones tend to turn the plastic sort of yellowish/ivory, rather than white too. Ours are at the ten year mark, so we will be replacing the hard wired very soon.

    One other option - take your vacuum cleaner with hose attachment and suck out any dust/debris around the unit's housing. The area needs to stay clean in order to register smoke and not be confused by other particles. Our alarm kept chirping until we did that, and it stopped... Worth a try!

    Don't know if this will help, Kelly, but with ours there's a particular procedure to follow in changing batteries. I always forget what that procedure is--I'm not the one who does it; hubs is--but I found this online: * First turn off power to the smoke detector at the breaker. (We've never done this, but it makes sense.) * Next, remove detector from mounting bracket and unplug power supply. * Remove battery. * With the battery removed, press and hold the test button for 15-20 seconds. (This is the step I always forget, but it's essential.) * Place new battery in detector and plug in power supply. * Restore power to breaker. * Reattach detector to mounting bracket. With the exception of turning the power off and on at the circuit breaker, this is what we do and it always works. Hope it does for you as well.

    Sorry to say hon, it really is that old so it needs to be replaced. Have some fun with it though. While its chirping, take it outside and put it on the ground and do what every one of us has dreamed of doing to a chirping smoke alarm and beat the daylights out of it! I mean whack the heck out of it and send that incessant chirping where it belongs!!! GO FOR IT GIRL!! And remember!! Have Fun while you do it!!

    Had the same problem, most cathartic solution is a baseball bat, but I am told that is not 'grown up'. It is signalling either it needs replacement, is dirty with kitchen grease, or maybe a temporary case of high humidity. . I hate the things - sure they save lives, but how many people are driven over the edge by them... use the bat with my blessing.

    I had same problem, eventually fire dept. came out and found a spider had made a home inside which caused the chirping...

    Replace it, for crying out loud!! How much could it cost?????
  • Amanda Amanda on Mar 23, 2016
    Anyone can call the non-emergency number for their local fire department and they will gladly come out inspect and install smoke detectors for free. (Especially handy for the ones located in vaulted rooms!) Our motto, and the reason we do our job, is "To protect and save lives and property". I'd MUCH rather see you for this reason instead of the alternative due to a faulty one! Hope this helps. Take care :)

    Try cleaning it with a can of air spray. We had this happen...were about to go crazy and discovered it wasn't even the smoke detector..it was the carbon monoxide detector in the same room. Lol
