Siemens SLSPCW-F (S54329-F41-A1) — SL Series high-fidelity ceiling speaker, white faceplate, FIRE lettering.
This is a speaker with no strobe: the Siemens ordering table lists its strobe type as none, so there is no candela rating and no strobe circuit. It suits ceiling audio coverage in a voice evacuation or mass notification layout where visible coverage is already satisfied. Siemens rests the case on intelligibility: 300 to 8000 Hz, and UL 464 at 520 Hz for sleeping areas.
- Indoor ceiling only; grille 6.25" (15.88 cm) diameter, 3.25" deep
- 25 / 70 VRMS dual voltage; taps 1/8, 1/4, 1/2, 1 and 2 W
- Ceiling output, UL and ULC alike: 75, 79, 82, 85 and 87 dBA at those taps
- Mounts to SLSPBBCW or SLSPBBCR boxes, or 4" square and 2.125" boxes; no trim plate needed
- In/out terminals, #12 to #18 AWG; 32°F to 122°F
Several trade listings show SLSPCW-F as red. The Siemens table shows white; red is SLSPCR-F (S54329-F41-A2). Do not substitute SLSPSCW-F (S54329-F42-A1), the white ceiling speaker-strobe.
