The First Alert BRK 7010B hardwire photoelectric smoke alarm with battery backup is a hardwire 120V single or multiple station smoke alarm designed for residential home use and institutional locations such as hospitals, hotels, motels, dormitories and other multiple family dwellings. This alarm is inter-connectable and can be installed and linked with up to 18 compatible devices (up to 12 smoke alarms and 6 compatible devices like bells, horns and repeaters) so that when one triggers, all alarms sound.
