3-3.9 Operating States
A network of ARIES Systems has the five distinct Off-Normal operating states
discussed in Paragraph 3-2.1. The normal network message display when there
are no active system events is as follows:
Figure 3-60. Network Normal Message Display
3-3.9.1 OPERATOR-DRIVEN MENU STATE
The system enters the Menu State when an operator presses the 0 Key and enters
the appropriate password as described in Paragraph 3-2.5.2.6. The operator will
be prompted to enter a network node number. The requested menu will be
accessible if the node number corresponds to:
• The control unit whose display is being utilized
• Another control unit in the same group as the control unit whose display is
being utilized
• Any control unit in a network configured for global operation
• The control unit whose display is being utilized is defined as Group 0
3-3.9.2 EVENT-DRIVEN STATES
A networked control unit will enter one of the event-driven states (pre-alarm, alarm,
supervisory, or trouble) when it is configured as Group 0 or when the event that occurs
is:
• Resident in the control unit or its associated peripheral devices
• From another control unit in the same group as the control unit
• From any control unit in a network configured for global operation
3-3.10 Network Outputs Activation
Control unit or SLC outputs activate when commanded on by operating instructions
contained in each networked control unit’s event output control (EOC) program. The EOC
program for a particular control unit is triggered by any event that transitions it from the
Normal Mode to any of the event-driven, Off-Normal operating states discussed in
Paragraph 3-2.1. The control unit must be configured to selectively receive and respond
to the event as described Paragraph 3-3.8, or the network must be configured for global
operation.
3-3.11 Operator Control Keys
The operator control keys are used to:
• Acknowledge receipt of initiating or monitoring-circuitry reports
• Silence alarm-notification appliances
• Transition one or more control units back to the Normal Mode.
These keys are functional if the control unit is configured as Group 0 or if the event and/or
activated appliances are:
• Resident in the control unit or in its associated peripheral devices
