Siemens C-DSC C-DSC-W Dual Sync Control Unit, Installation Instructions and Wiring

Installation Instructions and Wiring for and C DSC W white Dual Sync Control Unit C DSC red or C DSC W white Dual SYNC Control Unit is an optional accessory for a fire alarm system control unit The of the C DSC and C DSC W is identical and will be referred to as the C DSC throughout the remainder of this document This provides synchronization of the MC and HMC strobes and synchronization and silenceability to the MTH series of electronic audible When connected to a compatible polarity reversal type of notification appliance circuit there is supervision of the wiring from control unit through the C DSC unit to the End of Line device also see individual wiring instructions for the compatible appliances C 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 C DSC unit triggers the MTH series of electronic audible signals to sound in a synchronized temporal or march time pattern the audible signals 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 circuit s C DSC unit may be alternatively configured to synchronize conventional audible notification appliances The C DSC may be to sound audible devices at a temporal or march time pattern Or the silenceable input may be used to slave from an coded fire alarm system control unit Refer to P N 315 096363 for a list of compatible notification appliances and the maximum of devices allowed per NAC circuit SUPPLIED 2 Disconnect all power into the system including batteries 3 Mount

be slaved from the master DSC control unit number is determined by the master Non Silenceable N A C current divided by the slave input current ie 3A 005A 600 Cascading of the output of a slave to the input of another slave is not recommended 315 545280 5 PAGE 2 OF 4 Style Y Class B Style Z Class A Diagram for Conventional Appliances Diagram for Conventional Appliances The above configuration will
