This section presents examples of control units connection diagrams.
7.3.1.1 Daisy Chain Topology
In CHAIN topology, the connection is not redundant. Connecting units in this system does not guarantee operation of the system
in the event of communication cable damage. According to EN 54-16 norm, connections between VAS control units in a large
scale system must be redundant. Connections in CHAIN Topology are applied locally, and in the systems not responsible for
sending evacuation messages.
