My battery powered CO alarm keeps chirping. Tell me how to get a carbon monoxide alarm to stop chirping.

If your CO alarm keeps chirping, the battery may be low or weak. On First Alert® carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low. The way to get a carbon monoxide alarm to stop chirping is to replace the battery.
