Nothing beats the agitation you undergo when you have a fire alarm chirping non-stop and you are not in a position to turn it off. So keep reading to learn how to fix a noisy fire alarm.
Can you silence a chirping fire alarm?
Yes, you can. Your smoke alarm tends to chirp when it’s malfunctioning. Fortunately, silencing the chirp Is relatively easy. The first thing you need to do is determine if you have a standalone or hard-wired smoke alarm. Next, you need to determine if the alarm is constantly beeping or setting off randomly.
Below are some solutions to help Silence a chirping fire alarm;
Change the batteries
Old batteries are the most common problem when it comes to beeping alarms. Both standalone and hard-wired systems require batteries, and as power weakens, smoke alarms will beep every few minutes if the batteries are old and require replacement.
Power off the alarm
If you’ve got a hard-wired smoke alarm system, try flipping the switch on the breaker to see if the beeping ceases.
Reboot the alarm
If you have changed the batteries and switched the power off via the breaker and the alarm is still beeping, the system may need to be reset. Most alarms have a red reset button. Hold this down for 15 to 20 seconds to reboot the fire alarm.
Remove the batteries and hold down the reset button for 15 to 20 seconds. Then, reconnect the batteries and alarm. It will most likely beep once as evidence it is working, then it should stop.
If you have a hard-wired alarm, make sure to switch the power breaker off first before proceeding with the reset. And then turn it back on afterwards.
If resetting the alarm did not work, dust or dirt may be stuck between the wall and the detector inhibiting the sensors. First, separate the alarm from the wall and use your vacuum’s crevice tool. Then remove any debris on both the wall and alarm. Compressed air also works well to clean the area.

This can happen if your smoke alarm is overexposed to many elements, including steam in your bathroom or smoke in your kitchen. Or if it’s located too close to a heating vent. Alternatively, the fire alarm could be damaged and needs to be replaced.

How to stop a hard-wired smoke detector from beeping?
Below are some reasons your hard-wired smoke alarm keeps beeping when there is no smoke;
- Humidity: Humidity can confuse a detector’s sensors and trigger an alarm. Avoid installing units too close to bathrooms or other places with high humidity.
- Direct sunlight: Bright sunlight can also trigger false alarms, especially if the sunlight falls on the sensor chamber. The easiest fix, in this case, is to relocate the alarm away from direct sunlight.
- Heating or cooling vent: If a smoke alarm is installed too close to a vent, that vent can blow dust particles from the ductwork into the detector, leading to false alarms. This is more common when seasons change. And the heating or cooling is turned on for the first time in a while. To remedy this issue, relocate the smoke detector.
- Insects: Insects in a sensor can also trigger alarms. Cleaning the detector can eliminate this problem.
- Plugging other large appliances on the same circuit: A large current load can cause some alarms to go off. Switch the appliance to a different circuit by plugging it into a different wall socket.
How do you get a smoke alarm to stop chirping without a battery?
To stop your smoke detector from chirping or beeping;
Close the battery backup drawer
Hard-wired smoke alarms often have a backup battery for when the power goes out. This backup battery resides in a battery drawer. If the battery drawer is left open, your smoke alarm will beep every few minutes to signal that it is being opened. Ensure the latch is closed and fastened to keep the smoke alarm from chirping incessantly.
Replace the backup battery
If the latch was not in place and your smoke alarm continued to beep, your hard-wired unit’s backup battery may be dead. The backup battery may still run out even though your smoke alarm’s AC power line always provides power to the device.
To replace the backup battery in your hard-wired smoke alarm;
- On the side of your smoke alarm, there should be two screws that you have to remove.
- Once unscrewed, you will have to grab the handle and pull the battery compartment out.
- Grab an appropriate replacement battery and place it in the compartment.
- Put the compartment back together and screw it tightly.
- Once done, your smoke alarm is most likely to ring a couple of times to clear processor issues after a new replacement, and afterwards, unnecessary alarms should stop.
Reconnect the cables
Loose connections are one of the most common reasons fire alarms keep chirping. Reconnect and secure all cable connections to ensure everything is working properly.
You can also move the smoke alarm’s AC power converter into a different power outlet. Unfortunately, power sources can occasionally fail, causing your alarm to beep even when no batteries are present.
Reset the circuit breaker
Smoke alarms can frequently beep if your circuit breaker is malfunctioning. If the circuit breaker is tripped, the entire room’s wall outlets may lose power; if the detector is regularly experiencing outages, the chirping sound may be audible.
Reset the circuit breaker to stop your hard-wired smoke alarm from beeping.
To reset your circuit breaker;
- Locate the circuit breaker of the room where your smoke alarm is on the panel.
- Press the switch down and wait for 15 seconds.
- Slowly turn the circuit breaker switch back to the On position.
- Once you are done, your smoke alarm will restart, and afterwards, the chirping should stop.
- If the sound does not stop, you can test in another room.
Use the Hush Button
If your smoke alarm has a built-in hush button, you may use it to determine the problem. You can use the button to silence the fire alarm for 7 minutes as you troubleshoot.
If you click the hush button on your smoke alarm’s bottom panel and the chirping does not cease beeping, the issue is caused by internal hardware or software problems. And you should repair or replace the fire alarm.
Reset your hard-wired alarm
If the chirping doesn’t stop, you should reset your hard-wired alarm. In case of an
internal software issue, a factory reset will resolve the issue once and for all.
To factory reset your hard-wired smoke alarm;
- Unplug the power supply of your smoke alarm.
- Wait for 15 seconds for the device to discharge.
- Press and hold the protects button for 10 sec straight.
- Wait for the protections is a verbal countdown that will erase your setting.
Why does my smoke detector keep beeping even after I change the battery?
The chirping is normal, and it signals that the device is receiving power. If the chirping continues, your detector might have a residual charge from the previous battery. Take out the battery, hold down the test button for 15 seconds, and replace the battery.

Will taking the battery out of a smoke detector stop the beeping?
No. Taking the battery out of a smoke alarm will not make it stop beeping. Even after the battery has died, the detector maintains a residual charge that will keep the chirp going for at least seven days. To get the fire alarm to stop beeping without a battery, you must drain this residual charge by holding the test button for 15 seconds.
