About the 4903-9426
Wall-mount non-addressable horn/strobe for 4-wire operation, with red housing, white FIRE lettering and a 75 cd xenon strobe. The electronic horn and the strobe have separate terminals, so they can be wired to separate NACs and controlled independently; on one shared NAC they are not separately controlled. The 24 VDC strobe is switch-set for free-run or synchronized flash, with sync from Simplex synchronized flash modules, compatible panels or 4009 IDNet NAC Extenders.
Horn and strobe are not separately controlled when both are wired to the same NAC, and 16 VDC is the lowest voltage allowed at the last appliance under worst-case conditions.
