It can drive you to distraction, the constant unexplainable beeping of an electric smoke detector. Often it just needs the battery replaced but it may be a signal that it needs greater attention. This is a guide about troubleshooting ideas when an electric smoke detector won't stop beeping.
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!
A carbon monoxide detector has a shelf life of five to ten years and will beep constantly until unit is disconnected and replaced. Depending on the manufacturer some devices may beep and a green light is flashing others just beep
My smoke alarm was set off when there was a lot of dust during a DIY job. It wouldn't stop bleeping when I decided to replace the battery on completing the DIY. I just found the solution; there was still some dust in the sensor vent so I blew into it vigorously and replaced the battery. Voila, it worked perfectly.
Simple Three Part Solution:
a. Dust out all dust and debris from the metal battery connectors within alarm.
b. A New battery (square 9 volt) is properly placed with Positive Matching Positive (+) & Negative Matching Negative (-) and the little plastic hatch within is closed up with a click.
c. Finally, and MOST IMPORTANTLY - Flip the corresponding circuit breaker for a quick reset.
The chirping of the evil birds will now stop and never return...until you do something else stupid, that is. :) Cheers!
My fire alarm is beeping like there's a fire and we just changed the batteries! We even took some of the new batteries out thinking that would stop it, but it didn't. We can barely reach the alarms in the ceiling. We can not go hearing this alarm all night. What can we do or who do we call?
As a retired firefighter's wife, I always suggested calling your local fire department (the non-emergency number). They will answer most questions and may even come over to help you solve the problem. Sometimes they will supply a new alarm at a discount and install it for you. Never hurts to ask is one of my mottos.
2. Also if the inside of the alarm is dusty or full of cobwebs, it will do weird things like ring without the batteries. Take your vacuum to the open alarm(remove the outside housing) and give it a good cleaning.
3. Make sure the alarm is not hard-wired to the electrical system in the house with a battery backup. If this is the case, it will ring without batteries. 4. Finally, be aware that smoke alarms age and should be replaced about every five years depending on the brand.
My smoke alarm keeps beeping. How do you get them to stop chirping even with new batteries? They are hard wired, so does one need to shut off the breaker? Which one?
The smoke alarm is chirping because:
- The battery is dead
- The unit is not receiving hard wired power
- The unit is dirty
- The unit is broke
Make sure the replacement battery is good, that the unit is plugged in firmly. Use canned air to blow the dirt out of it. If it keeps chirping replace it.
My smoke detector has been removed and there is nothing there but wires. How do I stop it from beeping? It's driving us crazy and we are both in our 70s and can't climb up to fix the problem.
Have you tried flipping the breaker on your electrical panel?
My fire alarm started chirping this morning and it woke me up. I don't have the correct batteries to replace it, but I've tried everything else and it continues to chirp after I turn it off. How do I make it stop without getting a new battery?
You would actually have to undo it from the ceiling and unhook the wires. It is better and safer to find a way to get those batteries.
Why does my fire detector keep beeping when I am sleeping and everytime?
If it sounds like a chirp it means batteries need replaced. If it sounds like the regular alarm you may need to replace it assuming it's the kind that takes batteries. You don't want to get in the habit of ignoring the fire alarm sounding in case of a real fire!
My smoke detector won't stop beeping. I have done all of your suggestions. What else is there to do?
Sorry, you have to replace it. That means removing it from the ceiling, but don't do this yourself if you don't have good balance or the right stepladder. If you are a senior or low income, try calling the fire department.
I have detached the smoke detector from the ceiling electrical contact, but the chirping continues without stopping.

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.
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?

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.
When you have put new batteries in your electric smoke alarms and they won't quit beeping who do you call for a problem like this? Or what can you do?
