Maintenance
- Battery Replacement: The 9V battery should be replaced at least once a year, or immediately if the alarm chirps to indicate a low battery. The front-load battery door makes this process simple.

- End of Life: This smoke alarm has a 10-year limited warranty. It is recommended to replace the alarm after 10 years from the date of installation, regardless of whether it appears to be functioning.
