The Siemens SL2HSCR-F (S54329-F89-A1) is a ceiling-mount horn strobe from the SL2 series of LED-based notification appliances, finished in red with "FIRE" lettering and a clear lens. It is used in commercial buildings where audible and visible alarm notification must come from a low-profile ceiling device, and it works for both new installations and retrofits.
Key Features
- LED strobe technology significantly reduces current draw compared with xenon designs
- Six field-selectable candela settings (15, 30, 75, 110, 150, 177 cd) set with a tool-free slide adjuster
- Horn selectable for temporal or steady output with high or low dBA settings
- Meets the 20 ms light-pulse-duration requirement of the 2016 edition of NFPA 72, so it can share a field of view with existing Siemens xenon strobes
- Low-profile design with no visible mounting screws
