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

This document is a network architecture diagram for VA Hospital HVAC controls upgrades in Wilmington, Delaware (Project 211-1009).

The diagram illustrates a complete network architecture showing the integration of existing and new building automation systems across multiple VA Hospital locations. The system consolidates HVAC controls through new DDC (Direct Digital Control) systems that connect to existing TRANE SCUI controllers and Honeywell web-based controllers located in various mechanical rooms throughout the hospital complex. Key components include: four floors of central mechanical rooms (4th Floor Central Mechanical Rooms 40M2 with IP 192.168.1.140, and similar configurations for other floors), a Clinical Addition 2nd Floor Mechanical Room, and Building 17 CLC Mechanical Room. The architecture incorporates a 16-port network hub, integration jace (FX-70-4) for TRANE system integration, and multiple supervisory controllers (FX-70 series equipment). New backnets connect AHU and VAV controllers across the facility with specific IP addressing schemes (192.168.1.x range). The bill of materials lists required equipment including FX-70 Supervisory Controllers, FX-20 Supervisory Controllers, FX-50RTE Unidirectional Software, and a 16-port gigabit network switch hub. The system design ensures all existing TRANE SCUI controllers and Honeywell controllers integrate through one unified network infrastructure, with specific network panels and equipment tags identified for installation throughout the hospital's HVAC control network.
