No one wants to think about a fire in their home, but being prepared and recognizing signs of danger early can help keep you and your family alive and safe. The First Alert SA302CN Double Sensor Battery-Powered Smoke and Fire Alarm is equipped to detect smoke particles caused by both flaming and smoldering fires. For convenience, it allows you to mute false alarms remotely using any remote control and without compromising the alarm's functionality.

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.
