5-8.2.2 NETWORK GROUP 0
One control unit in the network can be assigned to Network Group 0. This control unit
serves as the master control unit for the network, and is capable of the following
interactions with all sub-groups in a selectively-signaling network:
• Displaying and logging all network events from all network groups
• Issuing acknowledge, silence, and reset commands to all control units in all
network groups
• Activating its outputs upon any initiating event from all control units in all
network groups
Figure 5-4 shows the possible interactions among the various members of a selectively-
signaling networked system with groupings and with one control unit designated as the
master control unit.
