Product Description The First Alert BRK SC7010B hardwire combination smoke and carbon monoxide alarm with battery backup is a hardwire 120V single or multiple station smoke and CO 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. The SC7010B detects two hazards with one simple unit and emits loud 85dB audible alarm. Carbon monoxide (CO) is a colorless, odorless, deadly gas that is emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, improper venting, and attached garages can also cause unsafe carbon monoxide accumulation. In addition to sensing unacceptable CO levels, the alarm also features a photoelectric smoke sensor which is particularly effective at detecting slow smoldering fires. The Frist Alert BRK SC7010B hardwire combination smoke and CO alarm with battery backup is packed with convenient features.
