S54430-A2-A1 SIEMENS

Product Overview 

The Siemens S54430-A2-A1 (Model FN2001-U1) is a high-speed Network Ring Card (NRC) designed specifically for the Siemens Desigo Fire Safety Modular and Cerberus PRO Modular systems (formerly XLS/V). It serves as the primary communication bridge between multiple fire alarm control panels and remote transponders, forming a robust XNET network. This card is a vital component for large-scale, multi-node installations, as it manages the data exchange across the network ring. The FN2001-U1 is engineered to maintain system integrity; in the event of a single wire or fiber fault, the card ensures the network continues to communicate by re-routing data in the opposite direction.

Key Features

• Networking Capacity: Enables the interconnection of up to 64 Desigo or Cerberus PRO Modular nodes on a single XNET network.
• Media Flexibility: Supports communication via twisted-pair copper wire or fiber-optic cable (requires optional SFP fiber modules).
• Fiber Support: Compatible with FN2006-U1 (Single-Mode) and FN2007-U1 (Multi-Mode) SFP fiber-optic converters.
• Fault Tolerance: Supports Class X (Style 7) wiring, allowing the network to remain fully operational during a single open or short circuit.
• System Integration: Plugs directly into a dedicated slot on the CC-5 or CC-2 card cage.
• Ground Fault Detection: Includes advanced onboard diagnostics to detect and report ground fault conditions on the network wiring.
• Speed: Provides high-bandwidth data transmission to ensure rapid event reporting across large campuses.
