How to Stop a Smoke Alarm from Beeping – A buzzer smoke detector gets nervous quickly, but this noisy alarm might be trying to tell you something. The detectors usually sound or Chirp when something is not right. The question could be anything from a dying battery to a malfunction in the alarm components. It is even more frustrating that you can not always tell which detector is making the sound. Look for a flashing red light to easily detect the culprit. Instead of ignoring the beep or disconnecting the alarm, get to the root of the problem, so your detector works properly.
How to Stop a Smoke Alarm from Beeping
If the battery does not fully connect the smoke detector, it cannot function properly. A consistent beep that occurs every 30 to 60 seconds can be a signal that the battery is dying. If you see an inconsistent sound, check the battery to make sure it is properly installed and that the connector is secure. Something clogging the battery can also cause a problem. Make sure the battery has full contact.
The battery can be a problem even in a wiring model. If the back-up battery is low, the wired detector may beep until the battery is changed.
Dirty Detection Camera
Dirt inside the detection chamber can cause the smoke detector to make sounds even when there is no smoke. Dirt may interfere with the sensor, which may cause intermittent chirps or false alarms. Check the cleaning instructions for your smoke detector before attempting to remedy the situation. If you have a wired detector, use the circuit breaker to turn off the power to the device while cleaning. Remove the cover to reveal the inside of the detector. You can use a vacuum cleaner with an accessory in the hose to gently suck the dust and cobwebs out of the unit.
Environmental factors sometimes cause a smoke detector beep. Moisture, steam, or extreme temperatures can cause smoke detectors to beep. If you have a smoke detector in an area such as a garage or attic that is not heated and cooled, extreme cold or heat may interfere with the detector. These temperatures can cause the battery to not be able to connect the detector reliably, which can result in a beep. A smoke detector in the main part of your home may sound after a sudden increase in temperature due to cooking or other cause.
Hardwire Power Reset
Wired smoke detectors may need a power reset to stop the beep, even if you replace the backup battery. Press the reset button to see if the detector simply needs resetting. You can also turn off the power from the unit to restart it. Turn off power to the unit by turning off the corresponding circuit breaker in the circuit box. Leave the power off for a minute or two. When reconnecting the power, listen for the additional beep. The simple reset may be enough to cure the beep. Press the test button after you reset it to make sure everything is working properly.
End of Life
If your smoke detector is between 8 and 10 years of age, the beep may be a sign that it is time to replace the unit. You can check to see if there is a manufacturing date on the back. Over time, the components that make the smoke detector work start to break and may not work properly. Even if the smoke detector is not so old, the beep might mean it is malfunctioning in some way. If you take a look at other possible causes of unlucky beeping, you may simply need to replace the entire unit.
