The BRK Brands, Inc. Model Number 7020BSL (CAT 1038335) is a wire-in, 120V AC 60Hz single and/or multiple station photoelectric smoke alarm with integrated 177 candela LED strobe light specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, public housing, dormitories and other multifamily dwellings as defined in standard NFPA 101. They meet building codes where AC with battery backup, silence, photoelectric smoke alarms are required. The alarms are inter-connectable with up to 18 devices, of which 12 can be smoke alarms. The BRK 7020BSL alarms feature a photoelectric smoke sensing chamber, an integrated 177 LED candela strobe light, an 85dB horn and sealed 3V lithium battery capable of providing backup power for alarm over 10 year alarm life. The Strobe Light is designed to provide deaf & hard of hearing individuals with a visual warning of a fire. The Smart Strobe has separate flash patterns for smoke/ heat and carbon monoxide dangers (when connected to a First Alert CO alarm). This helps a hearing impaired person better distinguish the danger present. The 177 candela LED strobe meets UL 1971 requirements and flashes at a rate of an average of 60 times a minute. The LED flash is also synchronized so when multiple units installed, strobes flash in unison.
