Description

First Alert’s series of Wireless Battery-Operated Smoke Alarms effectively eliminates the need for a wired connection and operates entirely on batteries. The latest advancement in a series celebrated for its intuitive use of technology, the First Alert Wireless Interconnect collection offers an abundance of options when it comes to creating the ideal safety network. Wireless inter-connectivity allows you to connect up to 18 alarms (a maximum of 12 smoke alarms and 6 carbon monoxide alarms) within your home! Should one First Alert Wireless Interconnect alarm sound off, the remainder of your Wireless Interconnect alarms will also trigger simultaneously and alert you and your home to any potential dangers. The communication distance (range) between any two First Alert Wireless Interconnect Alarms is typically 50 ft. (15 meters) inside of a home. Some features of a home, such as the number of floors, number/size of rooms, furniture and types of building materials used may reduce the range of wireless interconnect alarms. This feature allows for the maximum in whole home protection.
