I also need help! I'm not familiar with the First Alert system, but one of the detectors is chirping and I can't get it out of the ceiling. I need help! no one's around at this time of night to come over and disengage this thing!

If you can locate the smoke detector that is making the chirp remove it from the wall (disconnect the plug) and remove the battery. While it is disconnected press the test button. You will get a weak test sound. Keep holding the button until the sound dies away completely draining the energy stored in the system. Now hook everything back up, install the battery and press the test button. Your chirps should be gone!

My hard wired smoke detector began to beep but it doesn't appear to have a battery backup. This is 2014 and the cover of the detector says to replace in 2004. Do I have to replace the whole thing?

For the second time this week, our First Alert smoke/carbon monoxide detector has done the following:

one chirp
three long beeps
three long beeps
four short chirps
four short chirps
one chirp

The first time it did this, we replaced the batteries (this was a few days ago). Then it just happened again this morning. I'm assuming it's some sort of malfunction. It seems like it's making all Has this happened to anyone else?

I'm having the same issue. I've flipped the breaker off and unhooked them. STILL CHIRPING about every minute.

Having the same problem. Cleaned all of them removed the batteries and removed them from the ceiling. Then put them all back in and a hour later one starts beeping then an hour later the beep moved to another area of the house. Please help going crazy along with my two dogs

People you need to understand the life of a smoke detector is 10 years (or less for you smokers) and should be replaced after that amount of time. Quit screwing around.

I have three smoke alarms in my house (First Alert). They are wired into the house AC, but have battery backup. They are also wired to communicate with each other. One, the one causing the noise, is also a CO detector. In the last few weeks one of them has started giving me a single beep (let's call that E) or a triple beep (let's call that S), in the middle of the night for no reason. E is a signal to replace the battery, per the manual, although it should be doing it every hour, in that case. At first, I dutifully changed the battery (three nights in a row). S means smoke, but in that case it would be louder & continue until manually reset. There is no smoke. In fact, it DOES NOT go off when the neighbor's BBQ scent drifts through my house.

Finally called the electrician who installed them. The first time he came out, he said they were all old enough to be replaced & charged me a lot to do so. He's been out twice since, because the problem continued, always at night. The only thing he does is replace the offending unit (for free). There is no latch light on any of the three, so no clue which one started the fracas.

What gives!!??!! I'm losing sleep & the dogs are going nuts. Sometimes it triggers a dog fight.

Ceiling that holds the wires for the detector have a speaker or amplifier in it that is allowing us to hear, But instead of a continuous ,that you get when there is smoke is all round.
