Gent Vigilon VIG-MCC-EN-NOD-UPG Main Control Card Upgrade

VIG-MCC-EN-NOD-UPG is a Main Control Card (MCC) compatibility and upgrade item for the Gent Vigilon EN fire system, designed for use with the Vigilon and 34K control panels and network node backplane. It occupies Slot/Card 0 in the system architecture, serving as the central processing unit within the card cage configuration.

This upgrade item specifically interfaces with the Input/Output Card at Slot/Card 15 and the RAM (memory) card at Slot/Card 3 via a 40-way ribbon cable, helping to ensure coordinated operation across critical subsystems. It is compatible with Vigilon EN systems, 3404 and 3300 Mk1 Control panel backplanes, Loop Processor cards, and RAM/Network cards (RAM NC), as well as superseding or working alongside the VIG-MCC-V3+ variant.

Physical wiring and connection details, including terminal configurations and slot positioning, are documented in the installation manual and not reproduced here. The VIG-MCC-EN-NOD-UPG functions as a direct compatibility upgrade for legacy Gent Vigilon EN installations requiring MCC replacement or enhancement.
