About the 4903-9427
Non-addressable wall horn/strobe with a 110 cd xenon strobe and a piezoelectric horn, in a red housing with white FIRE lettering. It has separate horn and strobe terminals for 4-wire control from two reverse polarity NACs, and the strobe can be set for free-run or synchronized flashing. It mounts semi-flush or on the surface on a single gang, double gang or 4-inch square box.
The horn and strobe are not controlled separately when both are wired to the same NAC.
