Hierarchy for Display of Concurrent Events
The hierarchy for the display of concurrent events, from highest to lowest
priority, is as follows:
Lower-level events will not be automatically displayed if higher-level
events are active.
How Concurrent Events Are Displayed
The information shown on the ARIES display will change if the system is in
more than one state concurrently.
1. Level-1 Event Display
The upper line of the LCD display shows the time to release for the
first suppression zone that has begun to count down after you
acknowledge the alarm event (or events) that have triggered the
countdown. The time to release will continually decrease in one-
second intervals until the expiration of the time-delay period. The
lower line indicates the numbers of concurrently-active events for the
following Level-1 and Level-2 event types:
–
Discharges
–
Countdowns to Release
–
Aborts
–
Alarms
–
PAS Countdowns in Progress
Level-2 and lower-level events will not appear on the display as long
as any Level-1 event is active and is in process.
Figure 3-25 shows the appearance of the display when a suppression
zone has begun to count down.
