Wireless technology makes it possible for the detector to connect with up to 18 compatible First Alert wireless-enabled alarms to create a wireless safety network. These connected alarms can communicate with each other and sound in unison. The photoelectric smoke sensor is designed to reduce false alarms from cooking smoke or shower steam while remaining sensitive to real danger. The smoke detector has an integrated battery backup in case of power outages and features a single button to silence false alarms and test the unit.Eco-friendly, completely recyclable as an electronic device.
