Chirping Smoke Detector? Low Batters, Broken Detector, or Sign of an Electrical Problem?

GVEC Home® has provided electrical expertise and services in Gonzales and throughout South Central Texas since 1938! Something you may not think about calling an electrician for is a chirping smoke detector. While this issue may often be a simple fix, sometimes it could be signaling an electrical issue.

Low Battery

Chirping indicates an error with the smoke detector. The most common error is a low battery, so this is the first possibility you should consider. Swap the battery. Note that some smoke detectors will continue to chirp after a fresh battery has been installed. In this case, you will need to clear the error in the processor. Luckily, most units have a reset button that you press to do this. Resetting can also overcome chirping due to a power outage or surge.

Other Battery-Related Troubles

If that does not work, inspect the battery area closely. Ensure that the battery sits flush and the terminal is not obstructed in any way. Make certain that the battery door is closed and effectively securing the battery.

In Need of Cleaning

At this point, it is time to consider cleaning the sensing chamber. Clean the outside of the unit with a damp cloth. Clean the interior of the unit with compressed air but not too forcefully. Reinsert the battery, reinstall the unit and test the detector.

End of Life or Electrical Issue

If cleaning fails, you may want to call an electrician. It may just be that the detector has failed and must be replaced. However, if there is an electrical issue causing the unit to chirp, your electrician will be able to detect that. He or she may also be able to diagnose environmental issues, such as bad temperature calibration, humidity, condensation, excess airflow and so forth.
