SYSTEM OUTLINE

When SV9300 Units are installed at Remote Unit, and connected to a Main Unit over IP network, the Main
Unit system controls and maintains the operation of Remote Units as one single system. If a communica-
tion failure occurs between the Main Unit and Remote Unit, the Remote Unit automatically changes over
to a survival mode and operates as a stand-alone system.
