The First Alert SA320CN Dual-Sensor Smoke and Fire Alarm provides early warning of both flaming and smoldering fires. Additionally, its intelligent sensing technology is designed to cut down on nuisance alarms from cooking smoke or other common false-alarm triggers. A single button both silences and tests the smoke detector for simple operation. The battery-powered fire detector can be easily installed anywhere without wires.

  • Dual Sensors Detect Different Types of Fires

The First Alert Smoke and Fire Alarm comes equipped with two different sensors to offer the earliest possible warning of a fire. The ionization sensor detects flaming fires, such as grease fires or wastebasket fires, and the photoelectric sensor detects smoldering fires, such as when a lit cigarette ignites clothing or upholstery. Both sensors work together to provide comprehensive smoke and fire detection.

  • Smart Sensor Minimizes False Alarms

People sometimes disable a fire detector when it goes off due to cooking smoke or steam, even though in doing so they endanger themselves and their loved ones. Intelligent sensing technology in the First Alert Dual-Sensor Smoke and Fire Alarm is designed to distinguish between real fires and nuisances, reducing false alarms significantly so there is never a need to disable the alarm.

  • Battery-Powered Fire Detector Installs Anywhere

The battery-powered fire detector can be installed anywhere with no wires or electrician required. A low-battery indicator light and audible chirp let you know it is time to change batteries. The battery compartment opens without the need to remove the alarm from the mounting bracket, making battery replacements quick and easy.
