First Alert Dual Sensor Smoke and Fire Alarm, SA3210

Product Description

While all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. The fist alert Sa3210 dual sensor ten year alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning-regardlesss of the type of fire. Sometimes a fire can smolder for hours before erupting into flames.

Ionization sensing technology is generally more sensitive than photoelectric sensing technology at detecting these sorts of flaming fires. This alarm is powered by sealed, ten year lithium batteries to provide continuous protection for ten year without battery replacement.
