How do you stop a hardwired carbon monoxide detector from beeping?

To reset the alarm, the unit needs fresh air and time to burn the contamination off the sensor. Push and hold the silence button for 5 seconds to silence the alarm while contamination is being burned off the sensor. You may need to do this a number of times to give the carbon monoxide alarm enough time to reset.

Why is my smoke alarm chirping if it's hard

This is the easiest problem to solve. Most hard-wired smoke detectors use a 9-volt battery that is supposed to kick in if your home loses electricity. When that battery is running low, your detector alerts you with a chirp that it's running low. Replacing the battery solves the problem.
