About this item



Make your home always ready for emergencies with the First Alert SA320CN-2 Smoke Alarm. This practical device is equipped to detect smoke particles that are caused by both flaming and smoldering fires. For added convenience, the First Alert Smoke Alarm allows you to mute false alarms remotely using any remote controller and without compromising the device's functionality. Fast flaming fires tend to spread quickly and leave you a very short time to react, while smoldering fires burn long and can fill the home with smoke. The alarm's smart sensing microchip technology helps determine the difference between non-threatening conditions and real emergencies. In addition, the First Alert Smoke Detector also provides dual-sensor technology for maximum protection. It makes use of both ionization and photoelectric sensors to offer the earliest possible warning, regardless of the type of fire. It comes with two AA batteries and can go as loud as 85 decibels.
