The First Alert Dual-Sensor Smoke and Fire Alarm with 10-Year Sealed Battery makes use of both ionization and photoelectric sensors to alert you to danger in your home as early as possible, even if it's a smoldering fire. A single test/silence button mutes unnecessary alarms and tests function, while an end-of-life timer sounds when it's time to replace your alarm. The 10-year lithium-ion battery provides continuous power for up to a decade, and the alarm requires no hardwiring for installation.
