The First Alert Atom Micro-Photoelectric Smoke Alarm with 10-Year Sealed Battery is a fraction of the size of a standard alarm with the same amount of advanced protection. The alarm requires no battery replacements for its life. This alarm is powered by a sealed, 10-year lithium battery. A single test/silence button mutes unnecessary alarms and tests its function. An end-of-life timer sounds when it's time to replace your alarm. It meets UL217 standards and complies with legislative requirements for 10-year battery-operated smoke alarms. This product includes mounting hardware and is backed by a 10-year limited warranty.
