Siemens S54430-B8-A1 XDLC Interface Device Loop Card

XDLC S54430-B8-A1 is Siemens’ Class X Device Loop Card for the Desigo Fire Safety Modular/Cerberus PRO Modular system, serving as the interface that connects addressable X- and H-series devices to a Siemens fire panel. It plugs into one slot in a CC-2 or CC-5 card cage and is configured via ZEUS, the modular system configuration tool. The card uses a single network address and can accommodate up to 252 detectors and devices on its XDLC loop, with 16 diagnostic LEDs to monitor status, ground-fault detection, and zone-isolation circuitry. It initializes, operates, and maintains all devices residing on up to four Class A and eight Class B addressable circuits, and it transmits all relevant device and event data (Alarm, Trouble, Supervisory) to the Desigo Fire Safety Modular/Cerberus PRO Modular FACP while supervising the device loop. This model is UL864 10th Edition Listed and ULC-S527 3rd Edition Listed, reflecting compliance with core fire-safety standards for integrated systems.
