Siemens SL2HSWR-F — SL2-series LED horn strobe for indoor wall mount, red faceplate, FIRE lettering; part number S54329-F99-A1.
Reading the code: SL2 is the series, HS the horn-strobe appliance, W the wall mounting, R the red faceplate and -F the FIRE lettering, which is a marking and not a certification. An LED replaces the xenon tube, and because the strobe meets the 20 ms light-pulse rule of NFPA 72 2016 it can share a field of view with existing xenon appliances.
- 24 V regulated DC or FWR, operating range 16.0 to 33.0 V
- Multi-candela strobe, field selectable, flashing once per second
- Audible modes Continuous or Code 3, T3 Code 3 Sync, and T3/T4 with a DSC module

- No more than 105 SL2 strobes on one notification appliance circuit
Wall and ceiling are not interchangeable: SL2HSCR-F is the ceiling horn strobe and uses a different candela set. SL2HSWW-F is this same wall unit in white, SL2SW a strobe with no horn and SL2HW a horn with no strobe. Mount on the SL2SBB backbox or SLSGP single-gang plate.
