Network loops can be joined via physical bridge cards. There may be no more than two
Style 7 network loops connected in tandem. For every two loops that are interconnected
(using one physical bridge), there can be a maximum of three physical bridges used in a
star configuration. See Figure 1-4.{xe "Network 4100 Fire Alarm System: physical
bridge (overview)"}{xe "physical bridge: connecting loops with"}{xe "Network 4100
Fire Alarm System: loops"}

To be used as a network node, a 4100ES panel must contain the following:
CPU.{xe "Network 4100 Fire Alarm System: system design"}
System Power Supply.
4100ES Network Interface Card.
Optional slave cards.
Network connections require 4100-6014 Network Interface Cards (NICs). Each network
node requires a NIC. Once the FIP is a network node, it may be programmed to be fully
in control of other nodes, or to be fully passive, or anywhere in between.
