Kidde 51XBRFR24D Xtra-Brite Red LED Fire Alarm 24V DC 95dB

The Edwards 51XBRFR24D is a member of the 51XBR Xtra-Brite series — a family of combination audible/visual signaling devices designed for demanding indoor and outdoor life-safety and industrial applications. The unit integrates a high-intensity flashing red LED beacon with an integrated electronic horn into a single, compact housing, eliminating the need for separate visual and audible devices. Operating on 24 V DC, it delivers a rated LED service life of 148,000 hours for dramatically reduced maintenance intervals compared to traditional incandescent beacons. The double Fresnel polycarbonate lens offers shatter resistance and wide-angle light distribution, while a wide operating temperature range (−31 °F to 150 °F) makes it suitable for unheated equipment rooms, loading docks, cold-storage facilities, and outdoor installations. Standard mounting via ½" conduit, direct surface, or 4" octagonal box simplifies retrofit and new-construction installations alike.
