My smoke detector won’t stop beeping, even after replacing the batteries!

There are a couple things you should know about your smoke detectors before you consider replacing them.
Most smoke detectors in use today use electrical wiring with a battery backup. We replace the battery most often when it starts chirping but they SHOULD be replaced every year at the same time, like on a holiday. These smoke detectors store error codes which means the chirp associated with a week battery chirp is often a common error code. Many units retain that code even after replacing the old battery. To totally eliminate that chirp you must clear the error code that is being held in memory. The best way to do that is to reset the smoke detector.

Try the following steps:

1 Turn off the power to the smoke detector at your circuit breaker.
2 Remove the detector from its mounting bracket and unplug the power supply.
3. Vacuum or use compressed air to clean the smoke detector inside and out.
4 Remove the battery from the smoke detector.
5 With the battery removed, press and hold the test button for 15-20 seconds.
6 Replace the battery in the detector with a new one.
7 Plug in the power supply connector.
8 Reattach the smoke detector to the mounting bracket.
9 Restore power to the circuit breaker.

When power is restored, the smoke detector should chirp once. That annoying low-battery chirping should be eliminated.
One last bit of advice: If the smoke detectors in your home are 10 years old or older, they should be replaced. Your life and the lives of your loved ones are far too precious to risk on an old smoke detector.

Good luck and if this procedure fails you might need an in-home service call. Please call us to schedule service.
