FDCI183 TransponderProduct ManualCharacteristic Fulfill Chinese Standard of GB16806-2006 “Interlocking Control System”; 1 monitored inputs as collective detector connection; LED display of alarm and fault status; External 24VDC power supply; Microprocessor-controlled signal evaluation; Earth fault monitoring; With the Zener diode barrier, it is also possible to connect intrinsically safe detectors; Applicable in dry, dusty and humid areas in protection box.ApplicationFrom a functional perspective, we distinguish between the primary side and the secondary side of the transponder.The primary side is the connection to the FD18-BUS. The secondary side is the connection to the collectivedetection line.Compatible detector listType Max. detector per lineHI520/OP520 32DO1101A-EX/DT1101A-EX 25DF1101-EX 5FDL241-9-CN/DF1191/DF1192 1FDO181C/FDT181C 32CommunicationThe communication with the control panel is performed via the FD18-BUS. The configuration is performed onthe control unit or commissioning tool.Power SupplyPower supply of the primary side (FD18-BUS) is always ensured via the detector line FD18-BUS. Powersupply of the secondary side must always be ensured via an external 24VDC supply unit. The primary andthe secondary side are galvanically isolated.Operating modesThe transponder can be in either of the following operating modes:
