Figure 1-3 Sample of Alarm Details dialog showing state transitions of an Alarm object.
When an Alarm is raised by a particular Event, an Alarm object is created in the
Alarms Database maintained on the LGMapper server. When the Alarm is raised,
the Alarm object is considered to be an open Alarm and will remain open until
both of the following conditions are true:
• The state of the Alarm becomes up or cleared
• The assignment status of the Alarm becomes unassigned (i.e., not assigned or
excluded)
In the sample Alarm object shown in Figure 1-3, the Alarm object is closed since
the state is up, and the assignment status is unassigned.
When an Alarm object is closed, the next time a raise Event is received for that
object, a new Alarm object is created and maintained. This is how the time history
of Alarm objects is maintained in the Alarms Database.
