Alarm handling

Alarms can be individually configured to be handled by one or more user groups. When an
alarm occurs, it appears in the Alarm List of all users in the user groups configured to receive
that alarm. When any one of these users starts to work on the alarm, it disappears from the
Alarm List of all other users.
Alarms are displayed on a workstation's alarm monitor and optionally on analog monitors. This
behavior is described in the following paragraphs.

Operator Client | V3 | 2010.07
An alarm occurs in the system.
Alarm notifications appear in the Alarm Lists of all users configured for this alarm. Alarm
video is immediately displayed on configured monitors. If it is an automatically displayed
alarm (auto pop-up), the alarm video is also automatically displayed on the Operator
Client workstation's alarm monitors.
If the alarm is configured as an auto-clear alarm, the alarm is removed from the Alarm List
after the auto-clear time (configured in the Configuration Client).
On analog monitors, any quad views from VIP XDs are temporarily replaced by full-screen
displays.
One of the users accepts the alarm. The alarm video is then displayed on this user's
workstation (if it is not already displayed via auto pop-up). The alarm is removed from all
other Alarm Lists and alarm video displays.
The user who accepted the alarm invokes a workflow that can include reading an action
plan and entering comments. This step is optional - requirements for workflow can be
configured by the administrator.
Finally, the user clears the alarm. This removes the alarm from his Alarm List and alarm
display.
On an analog monitor group, the monitors return to the cameras that were displayed
before the alarm occurred.
To display alarm video, the Alarm Image window replaces the Live or Playback Image
window on the monitor that has been configured for alarm display.
Each alarm gets a row of Image panes. Up to 5 Image panes can be associated with each
alarm. These Image panes can display live video, playback video, or maps.
On an analog monitor group, each alarm can call up cameras on a row of analog monitors.
The number of cameras in the row is limited by the number of columns in the analog
monitor group. Monitors in the row that are not used for alarm video can be configured
to either continue with their current display or to display a blank screen.
Higher priority alarms are displayed above lower priority alarms on both analog monitor
rows and the Operator Client workstation display alarm rows.
If the Alarm Image window is completely full of Alarm Image rows and an additional alarm
must be displayed, the lowest priority alarms "stack up" in the bottom row of the Alarm
