System Events 22-3
Event Generation
As soon as a message-generating event occurs, a Call Request is automatically sent to
the
Primary Alarm Output ID
, and the
Secondary Alarm Output ID
if configured. (The
event is stored in the originating node's buffer until the event connection is activated.)
All events are transmitted in raw data format to the collecting node, which constructs
event messages and sends them to the display device(s).
An internal timer limits the time events are kept in the system buffer if the system fails
to bring the event connection up. If the timer expires, the buffer is cleared. The event
connection remains active until the event system detects that there are no events
occurring during the time period set for the
Line Idle Timer
. After the event connection
is cleared, the event system will repeat the above procedures if any events occur.
Displaying Events
To display any local events on the screen as they occur, press
[D]
at the Main Menu.
Event messages will continue to be sent to any destinations specified by the param-
eters described earlier in this chapter.
While this feature is activated, you cannot perform other operations on the
screen. Also, if the Primary Alarm Output device is unreachable, no local
events will be displayed.
A display at a collecting node looks like the example shown below. (A display at a
sending node will show only that node's events.)
