Siemens SC-LFS-WW-N — Acend series low-frequency sounder, wall mount, white faceplate, no lettering.
The sounder-only member of the Acend low-frequency family: an audible appliance with no strobe element, rated a low-frequency device per UL 464 and suitable for the sleeping areas where NFPA 72 calls for low-frequency signalling. Three DIP switches do the setting up — one picks high or low volume, high by default, the other two select one of four tone patterns. Continuous and T3 hold the UL fire listing; T4 and T4 low power are listed for carbon monoxide, the latter dropping to low power after four minutes.
