Fire Safety & Security Systems
The communication with the control panel is performed via the FDnet detector line.
The configuration is performed from the control panel.
Line separator FDCL221
A line separator is integrated into the radio gateway. In case of a short circuit, it
isolates the defective part on the FDnet detector line. This way it is ensured that
the faultless line part can continue to communicate with the control unit.
Regarding the topology, the radio detectors registered on the radio gateway are in
a stub. The stub branches off the FDnet detector line between the FDCW221 and
the integrated line separator FDCL221 of the radio gateway (see figure below).

The MC-Link connection in the radio gateway primarily serves for the connection of
the detector exchanger and tester FDUD29x (from SW V2.1). The detector
exchanger and tester makes it possible to extract information from the radio
gateway for the purpose of commissioning, maintenance and troubleshooting.
In addition, the MC-Link is used to update the firmware of the radio gateway. The
firmware is loaded from the PC to the radio gateway by means of the MCL-USB
