Simplex 4905-9938 Sync Control Module

Simplex 4905-9938 SCM (SmartSync Control Module) converts two conventional NAC inputs into a SmartSync two-wire NAC output.

To operating the strobe and the horn independently. The Simplex 4905-9938 SCM can be switch select to operate the horns as temporal coded. March time-coded (60 beats/minute), or on continuously. Strobes a re activate with 1 Hz synchronize flashes. SmartSync horns sound as Temporal or March Time pattern, or continuous, controlled separately from strobes on the same circuit. Strobes on the same circuit operate at a synchronized 1 Hz flash rate.
