Did you ever solve the chirping from the empty hole? I have this problem
DeAnne did you ever get this problem solved?
I am going crazy - I also have a removed fire alarm the somehow continues to beep where it used to be. Just an empty hole with wires some how continues to beep. I even turned the breaker off to stop power and it continues to beep.
I have a new alarm coming but Iām scared thatās not going to fix it.
Mine are beeping. Alarms down batteries out WTF. Has anyone found a resolution???
Having same problem. Removed all detectors on circuit, yet hole keep beeping. Donāt even know who to call. I sound crazy when i try to describe problem
Mine is chirping 3 times every 40 sec approx even after I replace the battery or removed the alarm device by unplugging from the ceiling what is actually happening I hear the sound from inside the hole
Hey so i was having this problemā¦. Dont know if itās a permanent fix but this was happening to me every time my house dropped below a certain temperature. If the house is properly warmed it NEVER happens, if the house is cold it beeps. Donāt know why, it just fixes it.
Okay, you are my hero! I searched Google for exact same problem and after reading your post about realizing the carbon monoxide detector was the problem I realized that was my problem too!! Feel stupid for not figuring it out but smart for finding your post. I owe you a couple of beers.
The alarm is most likely at eol (end of life). Check the manufacture date if its more than 10 years you have to replace it.
If you have an attic then you could possibly have a heat alarm up there.
Iāve heard of something similar. The fix was replacing the batteries in the affected unit. However it may be hard to track down the alarm that has the low batteries.
(Information for both replies) One possible method that may work is to look at the suspected alarm, If the chirp occurs when the led flashes try replacing the batteries on that alarm. It is also possible that the chirp could be coming from a non smoke and or carbon monoxide alarm. Look around the chirping could come from any electrical device, the offending device could also be blinking indicating a problem.
OMGā¦ THANK YOU!!! Youāre not insane, and neither am I. A nearby Carbon Monoxide detector that Iād completely forgotten aboutā¦ Low Battery.
I had this problem and thought it would be solved when a neighbor who is a retired electrician installed another hard-wired unit there. But the chirping started up again. It had temporarily stopped with the empty space when I turned the heat up, but it hasnāt stopped with the new detector installed.
Well, it turns out that the chirping was not coming from there, but from the nearest battery-operated detector that needed a battery replaced.

THANK YOU FOR THIS STRING. Iāve been dealing with this for 4 days. Losing my mind dismantling one detector at a time and legit at 2am was like how can there be beeping from a hole in my ceiling??!! It was a carbon monox detector plugged in near the ground that needed a new battery but somehow the reverberation sounded like it was coming from the ceiling. Thank you all for saving me a call to an electrician

Hopefully my experience may help others, one of our smoke detector started beeping a few days ago in the middle of the night (double chirp every 30 seconds indicating end of life of the device). We pushed the āhushā button and promptly replaced it a few days later. Yesterday we started to hear the same double chirp every 30 seconds again and could not figure out where the sound is coming from. We disconnected/removed all smoke detectors we can find, taken out the batteries, turned off power of the entire house and the chirping persists. We started to suspect itās left behind during construction of the house up in the ceiling and was prepared to cut through dry walls to see whatās up there. We got an electrician to come out see if they can find anything, spent almost an hour trying to figure out where the sound was coming from, andā¦. He found the beeping smoke detector in our trash can. The one we replaced just a few days ago and āhushedā with the battery still left inside. I feel stupid for posting this, but hopefully it will save people cutting up dry walls and paying $$$$ for a handyman to come out.

Nearby CARBON MONOXIDE was the issue! Replaced the battery in it. It stopped beeping and it was not the smoke detector afterall.
If your alarm is beeping from the hole:
1- it could be a nearby CO alarm, IMPORTANT: if it is alarming, contact the fire department, as the CO alarm may be warning you of CO.
2- there might be a different alarm (Usually if this is a drop ceiling or if a new ceiling was installed over the old one)
Up inside. If this happens, contact a electrician.
3- Attic alarm, a smoke/heat/CO alarm might be installed up in the attic, so it might be it
4- Not a alarm, check oven, microwave, refrigerator, dishwasher, washer and dryer, TV, phone, computer, clocks, radios etc
These sometimes make beeping noises that sound a lot like smoke alarms.
I only created an account on this site to say thank you for this post. You save me a lot of headache.
Youāre a genius. I replaced my smoke detectors a few months ago. One started beeping, so I thought it was a bad battery. I have four of them in bedrooms upstairs. I checked each of them by going in each room and closing the door. I decided it had to be one of my hallway ones. Every time I listened upstairs, it sounded like it was coming from downstairs and every time I listened downstairs, it sounded like it was coming from upstairs. I changed the batteries in both. It kept happening, so I disconnected both of them. It stopped, and then started again for a bit each night. My wife said to Google it, so I finally did and found this thread. I thought I had thrown my old detectors away after removing the batteriesā¦ until I found one I had not thrown away that still had the battery installed. That was it. Ugh.
2026 and here I am. We were going nuts wondering why there was chirping coming from a freakin hole lolā¦ switched all brakers off, replaced all batteries, yet the chirping persisted. And after reading on here just how many people realized it was their carbon monoxide detector, I looked around for one and found an old, unplugged one on the table below the said hole. I picked it up to look at it as the chirping happened, and lo and behold the CO detector vibrated lol omgā¦ took out the battery and silence! Itās so crazy how common this is! Thank you for bringing peace back into our home!
