Thereof, why is my hard wired smoke detector beeping?

Most hard-wired smoke detectors include a 9-volt backup battery that's supposed to kick in if your home loses electricity. If that battery is running low, your detector alerts you with a high-pitched beep. Remove the old battery and replace it with a new one. Press the “test” button and listen for a beep.

One may also ask, why does my fire alarm keep beeping after I change the battery? If you have changed the battery in your chirping smoke detector and it still chirps, you might think your detector is bad. Remove the detector from its mounting bracket and unplug the power supply. Remove the battery from the smoke detector. With the battery removed, press and hold the test button for 15-20 seconds.
