The UL-listed Battery-Operated Smoke and Heat Detector is a single-station alarm with an early warning signal. This alarm will activate in the event of a smoke or heat from a fire incident and its compact, 4 in. design lends it a discreet profile in your home or business. Powered by a 9-volt battery, this smoke and heat detector will protect you, your family and home during a power outage. When the battery begins to lose power, a low-battery alert will begin to chirp to notify you it is time to replace.
