Siemens FCI2017-U1 Peripheral Card S54400-A56-A1

Siemens FCI2017-U1 / S54400-A56-A1 Peripheral Card

The Siemens FCI2017-U1 (MPN: S54400-A56-A1) is a high-capacity, heavy-duty system periphery board that provides main structural support for the Siemens Desigo (FC2050) and Cerberus PRO (FC924) fire alarm control panels. This card is designed for large scale addressable systems and provides full power distribution, battery charging, network signalling and extensive system fault monitoring capabilities for up to 504 addressable devices.

The FCI2017-U1 comes with integrated dual loop cards that have built-in electromagnetic compatibility (EMC) surge protection, which guarantees reliable communication between the main operating unit and field sensors (such as smoke detectors, manual call points and monitoring modules) through the rugged FDNet/C-NET signalling line circuits.

Technical Specifications

Applications

1. Marine & Offshore Installations: Used extensively in marine fire prevention control panel frameworks (such as US Coast Guard-approved FC2050 / FC924 systems) to handle high vibration, ambient moisture and thermal stress.
2. Industrial & Commercial Facilities: Central operating hub for Desigo Fire Safety and Cerberus PRO fire alarm networks in processing facilities, data centers and multi-story complexes.
3. Pre-Action & Deluge Suppression Control: Easily interfaces with optional XCI2001-U1 releasing modules to control multi-hazard, double-interlock gas or water-based fire suppression lines.
4. Critical Distributed Signalling Systems Installed in retrofit zones where enhanced degrade-mode operations are required to keep notification appliances alive in the event of a loss of connectivity with the main CPU.

Guide From NDMarineTech’s Engineer:

1) Dual-Loop Isolation Safeguards: If wiring this board in a Class A (Style 6 or 7) configuration across distinct vessel fire zones, route your primary outward loop and return loop lines through separate physical cable paths. In the event of localized physical hull or bulkhead damage, this spatial separation preserves loop feedback continuity and prevents a total loop blackout.

2) Managing Auxiliary Power Budgets: The dual auxiliary 24VDC outputs provide a clean 1.5A max current limit. If your external device load demands near-threshold current, decouple that power draw from the board using an independent, system-monitored power supply (like the FP2011-U1 or FP2012-U1). This preserves the board’s internal thermal equilibrium and prevents unexpected shutdowns during high-stress alarm conditions.
