The smoke detector is designed to make a click once the battery needs to be replaced.The newer smoke alarm keeps some errors in the processor.The smoke alarm should clear the error after replacing the battery, but even if the battery is replaced, the smoke alarm may continue to sound.This also happens in smoke alarms powered by battery backup.If this happens, the only way to stop the chirping noise is to manually clear the processor's error by resetting the smoke alarm.Turn off the main circuit breaker in your home circuit breaker box and turn off the current flowing to the smoke detector.Remove the smoke detector from the mounting bracket on the ceiling and disconnect the power cord connected to the smoke detector.Remove the battery, then press the "test" button and hold it down for 15 seconds.The alarm will sound briefly and then the alarm will be muted.Put the battery into the smoke detector, reconnect the power cord, and put the smoke detector back on the mounting bracket.Open the circuit breaker.The detector will issue a chirp once to indicate that the power of the unit has been restored.Remove the battery from the smoke detector.Press the test button and hold it down for 15 seconds.The alarm will sound briefly and then the alarm will be muted.Put the battery back on the smoke detector.The detector will issue a chirp tone once to indicate that the battery is connected.If the smoke detector has a flashing red light, reset the smoke detector by pressing the "test", "mute" or "mute" buttons.Press "* 72" (star, 7, 2) to reset the smoke detector on the alarm system with the keyboard.
