Question: Fire Alarm Beeps for No Reason

Why does the fire alarm beep for no reason? There are no fire hazards.

By Jess [78]02/05/2014

Some smoke alarms beep if the batteries are dead or perhaps not put in correctly. Hard wired ones will have back up batteries that need to be replaced occasionally and they may beep if the are not wired properly.

There are some alarms also detect carbon monoxide. You may have a separate problem to investigate if it is a dual purpose alarm.

If it truly is broken, they are not that expensive to replace. It is very important to have a functioning smoke alarm.

Question: Smoke Alarm Going Off

My hardwired smoke detector is going off at the interval of every few hours. When one started the other two followed. All three are over 10 years old?

It is time to replace them. I am a fire fighter and depending on the type, they are to be replaced every 8-12 years.

All smoke detectors are supposed to be replaced about every 8-10 years, so you're due. New smoke detectors run about $5-$20, so it's not too bad, even for 3. I'm sure the fire department has a program to help if needed.

Some smoke detectors do take a 9-volt battery that can be replaced, but those usually chirp when the battery needs to be replaced - not go off. Even those should be swapped out every 10 years, so I'd still recommend replacement.

Another thing that can make some smoke detectors go off is if they get a lot of dust in them.

Question: Alarm Won't Stop Beeping

The smoke alarm sounded and there was no smoke anywhere in the home. The house is vacant and no appliances were on. I removed the one making noise, but when I reattached it, it went off again. Is it possible this one has gone bad?

Usually a sign it needs new batteries. Otherwise might be a bad smoke alarm.

Question: Smoke Alarm Keep Chirping

The in home smoke alarms were installed when the house was built 15 years ago or so. There are four. They are AC with a 9 volt back up. They started beeping or chirping one by one. We replaced the batteries one by one, with all new batteries. I took out all the units. Two of them still chirp with "no" unit. How is that possible, maybe something in the attic?

Smoke detectors have a shelf life of about 5 years. Try vacuuming out the inside of each unit because spiderwebs and dust can cause chirping as well. They may need replacement, call the local fire department. They are usually happy to come and check it out. If you have critters in your attic, they may have damaged the wiring, the main reason wired in units are not usually recommended. I am a firefighters wife.

Question: Smoke Alarm Chirping

My smoke alarms are unplugged, the batteries are removed, the mounts are still chirping. I even turned the breaker off. I am going crazy. Help! Suggestions?

Question: Smoke Dectector Beeps When Cooking

Every time we cook something the fire alarm always seems to go off. It doesn't matter what we cook. We can't even use the oven without it starting to beep. Is there a possible quick fix for this? I'm really just tempted to take out the batteries every time I cook if this keeps happening.

Question: Electric Smoke Detector Keeps Chirping

My electric smoke detector started chirping every 50 sec. How do I stop it? Do electric ones have a battery as well?
We had an electrical storm pass through last light; would that upset something? The electric smoke alarm upstairs is okay though.
Does one have to get an electrician in to change it? I hope not!
Thanks for your help.

Yes, the electric ones do have a battery - it's a backup battery for when the power goes off. We recently had the same thing happen and when we changed the battery, the chirping stopped. Hope this works for you.

Remove the cover and vaccuum out the inside. Dust and especially spider webs can make the sensors go off. If that doesn't do the trick, it may need replacing, as they do eventually wear out.

It is possible you may need to replace your detectors. If changing batteries doesn't work and they are more than a few years old, they need to be replaced.

Since they are brand new and if they came with a new backup battery then it's time to call an electrician because your home probably is having an electrical power surge problem.

Question: Smoke Detector Won't Stop Beeping

I was getting ready for work this morning when all of the sudden I hear this long continuous beep coming from my smoke alarm. I opened it up, there were no batteries, and it was still making this noise. So I thought that maybe there could be a back up battery or something, so I unhooked it and disconnected it entirely, but it still was making the noise! It seemed to be coming from the ceiling. And it's still doing it as I type! Can some one help me figure out how to stop this before I go absolutely insane?

By Rachel

By Poca10/27/2011

I would check to see if the heater has a battery or not as that is what is most always the problem with detectors beeping for apparently no reason. Even if it is hooked up to main, it just might have a battery. (?) Or google for "heat detector beeping" & check out those links. Good luck! Definitely not something to ignore, I would think.

Question: Beeping Smoke Detector

I know this sounds strange. We have electric smoke detectors. Are there batteries in them also? We have one that has started beeping and we can't stop it. Is there a battery in it or do we simply have to replace it? We have lived here 2 years (new) all the other batteries are OK. Our old house had electric smoke detectors and they never went bad. We lived there 15 years.

By Frugal Sunnie09/20/2011

Sounds like there is a short somewhere. You need to contact a licensed electrician-he/she will have the tools and training to track down your problem. Do it as soon as you can because this could be a fire hazard; if you are on a very tight budget you can call the local fire department non-emergency number and ask if they know of any programmes in your area to help you.

Question: Smoke Detectors Beeping

I recently changed the batteries in 3 hard wired smoke detectors. After about 1 day (happened twice) they all go off at the same time. Any advise please? By the way I tried holding the test button down with the batteries out but no luck.

By Chuck


Best Answer

By Dave07/19/2011

Most hardwired smoke detectors have a signal wire which tells all to sound when one goes off. I would take one out at a time, they usually twist on their base and have a plug in connector. When you find which is causing the problem you will probably need to replace it with the same or a compatible model. The other possibility is that when you changed the battery you dislodged some dirt which worked its way into the sensing chamber and causes the false alarm. Gently vacuuming out the detectors may solve the problem.

Question: Smoke Detector Keeps Beeping

Our electronic smoke detectors are going off during the night hours. This has happened last night 3 times. It is a warning beep because of a low battery. Does anybody know anything about this?

By Mark from Stafford, VA


Best Answer

By BrittneyH06/29/2011

Is your smoke detector also a carbon monoxide detector? I know with our smoke detectors the beep for a low battery is different than a beep for an alarm. My mother-in-law had a man come out for her stove and he said she had a severe gas leak, but nobody could smell it, but him, so it might be that and you just can't smell it.

Question: Fire Alarm Will Not Stop Beeping

There's about 6 fire alarms in my house. One alarm started going off then, all the other ones went off for about 30min. Finally it all stopped, but then started again. Now that all the beeping stopped, one continues to beep every minute.

I changed the battery and it still beeps, so I flipped the battery figuring it was in backwards. The darn thing still beeps, I pushed the test button and that didn't work. I don't know what else to do, and I need some sleep. I'd cut the power, but it's my grandparents house so I don't want to do anything I'd get in trouble for. Any advice would help.

I had the same problem with a fire alarm in our two bedroom apartment that continually beeped in our living room. One of the maintenance men had to remove the alarm and install another one.

It's not always the battery, maybe the alarms need to replaced with new ones. The alarms in your grandparents home are probably the original ones.

Some hard wired smoke detectors have a battery in them for back up if there is a power failure. If the battery is running low the smoke detector will start making a chirping sound just as you described.

I've never had any luck with the cheap smoke detectors. First place the battery is nearly impossible to put in. I just bought a new one a few months ago and had to take it down because of the chirping. I finally got a new battery in and it still chirps. Someone at the fire department told me they get dust in them. I blew the darned thing out and it still chirps. I'm going to get one of them that is a smoke detector and carbon monoxide detector together that plugs into the electrical outlet.

Here is some detailed help for those of us who are "mechanically challenged."

First, check your carbon monoxide (CO2) detector, if you have one, to make sure it is not the one beeping. (If it is, open windows to air out the house and get some help to fix the problem.)

Second, make sure the temperature in your home is within the tolerable range for your detector. (Mine has to be above 40 degrees F, and below 100 degrees.)

Third, change the battery. (Some steps below may not apply to your smoke detector, but hopefully this list will help anyway.)

How to change the battery:

Look where the alarm is attached to the wall, and remove the little plastic "stick" that is stopping the alarm from being turned, if present. (Mine had one in a slot on the right side. It just pulled off.)

Turn alarm in the direction of the arrows on the front of smoke detector. (Mine only turned a tiny bit, clockwise, then I had to pull the alarm straight away from the wall.)

It may be connected still by wires to the wall (or to a hole in the wall actually.) Squeeze both sides of the plastic piece where the wires come out of the back of the alarm and pull straight away from the alarm to remove the plastic "plug" holding the wires.

Now, hopefully, you can open the battery door to change the battery. My battery compartment had a piece of plastic (like a stick) on a spring that popped up when battery was removed. I had to push the plastic stick down into the battery compartment, then push the new battery on top of it so the battery door would close.

If it still beeps after you change the battery, try flipping the battery over. If it still beeps, try a different, new battery, and try it flipped over if needed.

If it still beeps then you may have to buy a can of compressed air to blow the dust out, OR buy a new smoke detector, whichever is cheaper/easier.


I hope this helps others to avoid the hassle I had to figure out how to change the stupid battery. Mine is still beeping so I'll try the compressed air or buy a new smoke detector once it is daylight.

There are two "types" of smoke detectors. One type detects smoke and the other type "sees" fire. Either of these 2 units do not have a long life span only about 5-7 years. Just because the smoke detectors "beeps" does NOT prove the smoke detectors are in functioning order. The only way to test the smoke detectors is going outside and lighting a fire (log, newspaper etc.) away from any buildings and then slowing bring the smoke detector near the smoke and flame to hear if the smoke detector alarms. If no alarm sounds the smoke detector must be thrown away and a new one purchased, usually less than $10.00. More than 5,000 people die each year in house fires, most could be avoided if the smoke detector worked. PLEASE check all of the detectors in our house. Your life is worth more than a few bucks.

P.S. Where is your fire extinguisher? It should be placed near the exit of your house or work. NOT IN THE KITCHEN! If the fire is in the kitchen how would you reach the fire extinguisher? As you are exiting the building and the fire extinguisher is near the exit and you believe you can put the fire out then use the fire extinguisher at hand. Remember this acronym - PPS Pull the pin, Point the nozzle, Pull the handle, Sweep the base of the fire. If the fire is not contained get the heck out of the building, NOTHING in the building is worth your life.

Archive: Smoke Detectors Won't Turn Off

I recently purchased a home which was built in 2003. When I moved in I was informed by my neighbors that my smoke alarms were going off. They had to contact my realtor to have them removed. Now that I am here, I replaced all the batteries in the smoke detectors and checked them for proper operation. The problem comes when I install them and plug them into the power plug. They begin to alarm and only stop after I remove them from the power plug.

What do you believe the problem is and what do you recommend to correct it?

Thanks,
Jay from Lehigh Acres FL


RE: Smoke Detectors Won't Turn Off

I don't know what the problem is but if I were you I'd contact the local fire department and ask them if they have a program that checks smoke detectors. Many fire departments offer this as a free service and maybe they could either tell you the problem or recommend an electrician to fix this. Good Luck and please don't sleep without the alarms working properly. (01/16/2006)

By Connie A.

RE: Smoke Detectors Won't Turn Off

I also don't know what's wrong with your detectors but we bought a home the same year and have the same problem. We called out the fire dept. to make sure there was no fire since we had lost our previous home the year before to a fire. They told us to call an electrician, expensive for us. I went out and bought some battery operated smoke and fire detectors and put them in the home until we save enough to have an electrician come out. The one who did gave us an estimate of $500 to check and replace what's wrong. Being paranoid about fires, I would buy some to put in the house and would never sleep in a home without one.

RE: Smoke Alarms Won't Shut Off

Before going through any expense; try cleaning each of them thoroughly; we had a small bug in one of ours that kept setting it off; with 9 smoke detectors in the house it took awhile to figure out which one was the problem; after cleaning each of them and installing new batteries problem was solved.

RE: Smoke Alarms Won't Shut Off

I agree with Connie A. Ask your local fire dept to come and check it out. We also had that happen. My husband changed the battery too, didn't help. He also shut off the breaker that fed power to the smoke alarm. It didn't work either. We just bought a new one - they're fairly cheap now. Good luck. (06/18/2008)

RE: Smoke Alarms Won't Shut Off

Ok, I figured it out! After the 3 worst minutes of my life (it hurt more than labor) & I finally got them to stop insanely screaming at me, and they just beeped, beeped, beeped. By the way, I'll need to train the local fire dept on this, because they couldn't figure it out either. I took all of the batteries out of them, shut the MAIN BREAKER off for about a half hour, of course I opened up all the windows to air the place out. Then I put all the batteries back in & turned the main breaker back on. No beeps for the past 15 minutes, so I think we're good. After I reset all of the clocks in the house, I'm headed to the doctor to get my damaged eardrums repaired. (08/29/2008)

By ~Me*

RE: Smoke Alarms Won't Shut Off

If your hard wired interconnected smoke alarms are going off, the primary source of the problem should have a blinking red light. Normally all detectors have a solid green or blinking green light. Remove the offending some detector and remove the battery. This should stop the alarm. You then need to assess if the problem is the unit itself, or if it just needs a a new battery. I just had a power failure in my home, and it knocked out one of the units, which set off the whole system. (09/10/2008)

About a year ago we had a severe storm that tore a 20 ft hole in our roof. Contractors came out, and repaired the roof, drywall, and paint. Now it's as good as new. Fast forward to yesterday I'm on the computer working and my hard wired smoke detectors all start going off. I quickly ran through the house checking for fire/smoke, thankfully I found nothing. I then contemplated one of the batteries went dead so I pull all the batteries, still no luck.

Next, I went to the circuit breaker box and selected multiple GFI breakers to off position. After waiting a few minutes I switched back on the breakers and they started going off again. Being it was late on Saturday and we were not in danger of a fire I decided I would research further and possible call an electrician for Monday.

After searching the internet on this subject I've come up with the following repair opportunities:

  • replace batteries and check
  • replace detectors and check
  • call electrician and spend min $500

Any assistance would be greatly appreciated. Oh yes, I'm not sure if the home damage occurring is relative, I personally don't believe so or I would have had an issue before now. Thank you.

RE: Smoke Alarms Won't Shut Off

We had a hard wired smoke detector go off after we'd had a new roof put on.
