The Siemens – Fire Safety `Class X’ Device Loop Card (Model XDLC) is the interface used for connecting Siemens addressable, intelligent `X’ as well as `H’-series devices.

Each Model XDLC plugs into one (1) slot of the Model CC-2 or Model CC-5 card cage. Programming for Model XDLC is accomplished via the Desigo Fire Safety Modular system custom-configuration tool, Zeus-D. Model XDLC takes one (1) address on the network, communicating up to a total 252 detectors and devices. Model XDLC has 16 LEDs for diagnostic purposes, and provides ground-fault detection and zone- isolation circuitry.

Specifications

The `Class X’ Device Loop Card (Model XDLC) initializes, operates and maintains all devices residing on up to four (4) `Class A’, eight (8) `Class B’ addressable circuits. Model XDLC communicates all relevant device and event data (`Alarm’, `Trouble’ and`Supervisory’ commands) to a Desigo Fire Safety Modular (Desigo Modular) fire- alarm control panel (FACP), and supervises the device loop circuit.

Model XDLC is polarity insensitive via SureWire technology, which greatly reduces commissioning time normally spent tracing down crossed-field wiring. Model XDLC communicates detector data, such as sensitivity of intelligent fire detectors and logic-function information, to the Desigo Modular Operating Unit (Model FCM2041- U2), which is located within a given Desigo Modular system. Each device loop card supports four (4) `Class A’, eight (8) `Class B’ circuits for up to a total of 252 addressable devices – as well as relay and audible bases, remote lamps and duct-detector housings in any combination.

The microprocessor in a Model XDLC controls the on-board isolation, in case there is a fault (short) in any of the circuits, thus allowing the other circuit to continue operating. For continuous protection,
the on-board microprocessor continues to operate even in the event of a CPU failure.
