8 ES Net Networking
Use the ES Net Network Interface Cards (NICs) to expand a 4100ES to an ES Net network system. Install a NIC in a 4100ES host panel to
connect to up to 98 other network nodes. Examples of other nodes include other host 4100ES panels, 4010ES FACUs, 4007ES FACUs, or
TrueSite Workstations (TSWs). A node is a self-sufficient FACP that controls appliances and devices, and also has the capability to control
and communicate with other nodes.
In addition to carry fire alarm events, the ES Net Network can also be used to carry inter-panel audio notification messages and two-way
firefighter phone communications between 4100ES nodes over Ethernet or Fiber links (DSL links not supported). Refer to the ES Net Digital
Audio Controller Installation Instructions 579-1408 for information about Audio over ES Net and the ES Net Digital Audio Controller card. .
The ES Net network supports multiple topologies of diverse interconnections between ES Net Nodes. These connections include bridged
rings, spurs, or hub/star like topologies. The only limitations are the maximum number of bridged rings; 4, and the available fire ports on
the ES Net NIC card; up to 6.
A ring configuration consists of nodes that are connected to each other forming a closed loop (Class X), see Figure 65.
A hub/star configuration consists of several nodes connected directly to one common node, see Figure 66.
This configuration can be redundant (Class X), as two links can be setup between the common node and each of the remote nodes. It
can also be non-redundant (Class B) with a single link setup between the common node and the remote node. A non-redundant (Class B)
configuration provides no alternate communication path between two nodes, therefore, a single fault in the network could segment the
network.
A multi-ring ES Net network with two bridged rings, and a single panel connected through a fire spur is shown in Figure 67.

Link could be Ethernet,
DSL or Fiber optic.
