Secon9:SystemIntegraonandNetworking
Topics in this secon cover integrang the controllers into a building automaon network. These are advanced reference topics
for control technicians and engineers.
The controllers can be installed as standalone controllers or they can be connected to a BACnet MS/TP network. The topics in this
secon are reference material for control technicians or engineers who are planning, installing, and seng up controllers that are
connected to a network.
In addion to the informaon in this secon, you will also need the following informaon.
• Detailed plans and drawings for the building automaon system.
• Informaon about the facility LAN including routers, switches, and network rewalls.
• Sequences of operaon for other BACnet devices that will monitor or interact with EZvav controllers.
