Siemens SC-ST-WW-F, part number S54361-F6-A2 — an ACEND series wall mount LED strobe with a clear lens, white faceplate and FIRE lettering.
This is a strobe alone: no horn, and its listings are the visual ones. Candela is set by a slide switch with no tools, so one catalogue number covers a corridor at 15 cd and a large room at 185 cd. Siemens states the LED meets the 20 millisecond pulse duration of NFPA 72 2022, so these and xenon appliances may share a field of view.
- Six field selectable settings: 15, 30, 75, 110, 135 and 185 cd
- Current draw at those settings 24, 27, 39, 68, 93 and 143 mA at 16 to 33 VDC
- Strobe listings UL 1638, UL 1971 and CAN/ULC-S526-16, indoor only
- Operating 32 to 120 °F, humidity 93 percent; weight 225 g or 0.49 lb
- Synchronised by Cerberus PRO and Desigo panels on the Siemens Sync Protocol
