Tip: Troubleshooting A Beeping Smoke Alarm

I had the same issue. My detector beeped loudly once a minute; and another one beeped once a minute, so beeps were heard every 30 seconds from 2 detectors. I vacuumed the units, turned off circuit breaker, disconnected wire unit from detectors, replaced batteries, held test button with battery out and then with battery in. None of this helped. All detectors had green solid light. I tried to solve all day and got a headache of course.

Finally (and this is noted by others too), I checked my plug-in (stand alone, not connected/wired to house or to smoke detectors) carbon monoxide detector (Kiddie brand, bought about 3 years ago; smoke detectors came with new house, now about 8 years old). I had just quickly plugged the carbon detector units into outlets and forgot about them. The carbon monoxide detector was going off! It had a red light flashing. My second carbon monoxide detector (Kiddie, same as this one) was NOT alarming and had steady green light! I unplugged the flashing carbon detector and INSTANTLY all smoke detectors were quiet Yikes! There was no carbon monoxide, I'm not sure why it went off.

So I'd suggest if you have wired/electrical smoke detectors to try unplugging various other things; sensor lights, alarms, small appliances, anything recently plugged in, etc. It might not make sense but it's an easy quick thing to try before trying complicated or expensive solutions, and to avoid headaches! Good luck!

    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.

    By Stephanie [149]01/30/2014

    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.

    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.

    Question: Smoke Detector Keeps Beeping

    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.

    Best Answer

    By Dave [3]07/19/2011

    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: Fire Alarm Beeps for No Reason

    By Irwin W. from Danville, CA

    Best Answer

    By Jess [95]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.

    Smoke alarms store error codes. If the beeping continues, and you have a wired in system with battery back-up: 1. turn off the main circuit to the smoke alarm 2. remove the detachable part of the alarm 3. remove the battery 3. with the battery OUT of its compartment, hold down the TEST button for about 15-20 secs 4. reinstall the battery, or replace it with a new one if the original is dodgy 5. reattach the alarm with battery in place to the base. 6 Turn on mains power. It will work again without chirping ('cos you have reset the error code for chirping [usually 'cos of low-bat]).

    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)

    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.

    My smoke alarm won't stop beeping. One alarm started to beep, I replaced the battery, then another started. I have 5, replaced all with new batteries, still beeped (about once every minute). Replaced all the alarms, still beeps, disconnected all alarms, the house still beeps. Would there be a relay, and where can I find it. Help my family is going crazy, it's been 3 days.

    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.

    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)

    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)

    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.

    Try taking a vacuum and blowing them all out. Even a cob web that has gotten in or a speck of dust will set them off. I had this problem and once I did this, but I used a blow dryer problem was solved. Julie (11/19/2008)

    We had that problem when we first moved into our house 10 years ago. The place had been empty for several years and I had cleaned it thoroughly before we moved in. However, I didn't think to open the smoke alarms and vacuum them. I do now every time we check the batteries. It cured our problem in no time. Good luck. (11/19/2008)

    We had a hard wired smoke detector go off after we'd had a new roof put on. I believe that when the old roof was off that moisture got into it from the open roof and that was coming through the attic. When the fire department was out I told them about the new roof and they told me that's what caused it was it malfunctioned due to moisture. (11/19/2008)

    I believe they're supposed to be replaced every 10 years anyway due to malfunctioning, just to be safe. (12/29/2008)

    I have a hard wired smoke detector system with individual battery backup. My system started single chirps every 30 seconds 3 days ago.

    I have a two story house and my smoke detectors are chirping every 5 seconds. I tried looking for the back up power source and I could not find one. If someone could help that would be perfect.
