Simplex 4905-9835 Temporal Code 4 Module

The Simplex 4905-9835 offers 3 selectable operation modes. First, Synchronized operation; Second, Unsynchronized operation; Third, Stand-Alone operation. Consequently, the synchronized operation allows a separate and dedicated control NAC to both activate and synchronize the Temporal Code 4 output timing of up to 20, Simplex 4905-9835 modules. While, the unsynchronized operation also allows the separate and dedicated control NAC to activate the Temporal Code 4 output timing of up to 20, 4905-9835 modules, but without synchronization between the modules. Finally, Stand-Alone operation allows the input NAC in alarm. Additionally, in order to activate Temporal Code 4 timing for NAC dedicated for CO gas alarm, no fire alarm signals are available, and no control NAC is used. For both Synchronized and Unsynchronized modes, when the control NAC is off, the module output NACs will follow the fire alarm signals of the input NAC.
