When a carbon monoxide alarm goes off, you should always take it seriously. Infrequent and occasional chirps often point to a low battery, a faulty device, or dust buildup (this usually affects smoke detectors and not standalone CO detectors). A continuous alarm signals an emergency, and you should immediately evacuate and call 911. When it comes to carbon monoxide in your home, it’s better safe than sorry.

If your hardwired smoke alarm keeps going off, it could be because the backup battery needs replacing. When replacing the battery doesn’t stop your smoke alarm from beeping, try holding the reset button for 15 to 30 seconds or removing dust from the openings in the alarm. If it continues to chirp, it could be faulty and require replacement.
