Siemens S54329-F17-A1 Strobe Ceiling Horn Fire Alarm

Siemens S54329-F17-A1 SLSCW-AL Strobe Ceiling Horn is an indoor, ceiling‑mounted horn‑strobe appliance from Siemens’ SL2/SLSC family, finished in white. This 24V DC powered device combines audible horn signaling with an integrated LED strobe and offers field‑selectable candela settings of 15, 30, 75, and 110 cd to meet NFPA 72 requirements across different spaces. It operates from a regulated 24 V DC supply (16–33 V) and supports both continuous horn and Code 3 signaling, with the strobe synchronized when used with compatible Siemens fire alarm control panels using the Siemens sync protocol. The SLSCW-AL is UL-listed for indoor use under UL 1971 and UL 464 and ULC-listed for Canadian installations, with ADA and RoHS compliance. It’s designed to integrate with Siemens FACPs, including 50‑point and 504‑point addressable panels and Modular FACPs, allowing scalable notification in spaces such as corridors, classrooms, lobbies, and other interior environments requiring combined audible and visual alerts.
