Bosch FNM-320-SWH Conventional Surface-Mounted Sounder, White

This sounder used in conventional fire circuits provides output up to 112 dB(A) via its loudspeaker. It mounts directly to the wall with a surface-mounted box; its white housing suits office and hotel corridors. Due to the 9–30 VDC range, the same product can be stocked for both 12 V and 24 V panels. Reverse polarity protection prevents device damage when terminals are incorrectly connected in the field and shortens fault search time during commissioning.
