S02 - 01 - VA Hospital - Complete Network Architecture.pdf

This is a network architecture diagram for a VA Hospital HVAC Controls Upgrade project located in Wilmington, Delaware (Project 211-1009, R-1). The diagram illustrates a complete network architecture for integrating heating, ventilation, and air conditioning control systems across multiple hospital buildings and mechanical rooms.

The architecture includes multiple TRANE control units (TRANE BCU-1 through BCU-4 and SCU-1 and SCU-2) positioned throughout existing facility locations, including the 8th floor East Mechanical Room, Main HVAC Shop (Building 16), and 4th Floor Central Mechanical Rooms. The system incorporates new Direct Digital Control (DDC) supervisory controllers that will bacnet to newly installed AHU and VAV controllers across various building zones and floors. Integration components include a TRANE System Integration JACE (FX70-6) serving as the central hub for existing TRANE summit (SCII) controllers, Honeywell Web (UACE) controllers, and OWS with FE Field Servers. CAT-6e cabling connects distributed equipment throughout the facility. The bill of materials specifies multiple FX-70 supervisory controllers, FX-20 and FX-5 controllers, LP-FX2011 controllers, and a 16-port Gigabit network switch hub. The diagram notes that all new DDC systems shall integrate with existing TRANE summit (SCII) controllers and Honeywell Web controllers via network integration through two network hubs as shown, with specific labeling requirements for all new and existing control panels.
