Siemens Dsc Dual Sync Control Module Fire Alarm Used

  
This listing is for a used DSC Dual SYNC Control Unit for your fire alarm systems. This was pulled from a working system that was just upgraded. The DSC Dual SYNC Control Unit is an optional accessory for a fire alarm system control unit. This unit provides synchronization of the MC and HMC strobes and synchronization and silenceability to the MTH series of electronic audible signals. When connected to a compatible polarity reversal type of notification appliance circuit, there is supervision of the wiring from the control unit through the DSC unit to the End-of-Line device (also see individual wiring instructions for the compatible appliances).

The DSC unit triggers the strobe lights to flash at a rate of 1 to 1.1 flashes per second (60 to 66 flashes per minute). The DSC unit also triggers the MTH series of electronic audible signals to sound in a synchronized temporal or march time pattern, the audible signals may also be silenced while the strobes continues to flash. The unit can support two Style Y (class B) or one Style Z (class A) notification appliance circuit(s). The DSC unit may be alternatively configured to synchronize conventional audible notification appliances.

The DSC may be configured to sound audible devices at a temporal or march time pattern. Or, the silenceable input may be used to slave from an existing coded fire alarm system control unit.
