About the 4905-9938
A SmartSync control module that converts two conventional NAC inputs into one two-wire SmartSync NAC output. One NAC controls the horns (on-until-silenced) and the other the strobes (on-until-reset), so horns can be silenced while strobes keep flashing in 1 Hz sync. Horns are switch selectable for temporal, march time (60 beats/minute) or continuous.
For Class A output, mount the SCM within 20 ft (6 m) of the control panel and use metal conduit.
