First Alert SA320CN Dual Sensor Battery-Powered Smoke and Fire Alarm

Utilizes both ionization and photoelectric smoke sensors for optimal performance.

Intelligent sensing technology reduces non-emergency or nuisance alarms.

Operates on 2 AA batteries (included).

Detects both flaming and smoldering fires with dual sensors.

Emits a loud 85 dB alarm for ample warning.

SA320FF designates SA320CN package in Frustration Free packaging with UN2911 labels for ion smoke alarms.

While all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. This alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning--regardless of the type of fire. Sometimes a fire can smolder for hours before erupting into flames. Photoelectric Sensing Technology is more sensitive than Ionization Sensing Technology at detecting these sorts of smoldering fires, like those caused by cigarettes burning in couches or bedding. Other fires erupt into flames quickly, like kitchen grease fires or fires fueled by paper burning in a wastebasket. Ionization Sensing Technology is generally more sensitive than Photoelectric Sensing Technology at detecting these sorts of flaming fires.
