A beeping smoke detector usually indicates a low battery. Try replacing the battery; if the beeping continues, it might be time to replace the smoke detector itself.

Can a smoke detector detect carbon monoxide?

Where is the best place to install a smoke detector?

Install smoke detectors on every level of your home, inside bedrooms, and outside sleeping areas. Mount them on the ceiling or high on the wall for the best results.

How do I test if my smoke detector is working?
