Configuring Alarms
Virtual Alarm
have disabled global alarm contribution for all alarm levels, then the global alarms are not
generated.
In the Layouts tab, you can assign a global alarm to a layout element that supports alarm
reporting, like a UMD or an alarm monitor: in the Properties pane, the lists of alarm levels
that can be assigned to a monitor include the item GlobalAlarm, along with all the
individual alarm levels.
You can select this global alarm not only as an alarm status, but also as a text label. When an
individual alarm is in Error, its friendly name will contribute to the global alarm text value.
When the global alarm level is assigned to an alarm monitor, the text values for all
contributing alarms currently in Error will be visible.
See Configuring Video Monitors , on page 255, Configuring UMDs , on page 286,
Configuring Alarm Monitors , on page 293, and Configuring Subtitling Monitors , on
page 296), for detailed instructions.
Virtual Alarm
A virtual alarm allows you to derive a result from the status of one or more existing alarms.
Any alarms — including other virtual alarms — can be combined together to form a new,
higher-level virtual alarm. Since a virtual alarm can be composed of virtual alarms other
than itself, there can be many levels of virtual alarms within a particular virtual alarm. At this
time there is no limit to the number of levels that a virtual alarm can have. See
Creating
Virtual Alarms on page 177.
Sub-Alarm
A sub-alarm is an alarm that contributes to the status of a higher-level virtual alarm. The
effect of a sub-alarm’s contribution is determined by the way in which the higher-level
alarm is configured.
Alarm Monitor
Alarm monitors help you see the status of global and virtual alarms, but their use is not
limited to this type of alarms. When any alarm level is assigned to an alarm monitor, the
status of this alarm will be shown. When using the global alarm at the text label level, it will
Note: If you choose to configure your multiviewer system with a large
number of logical sources (i.e., more than 1500), you should disable global
alarm contribution for all alarm levels in the sources table, to improve the
system performance.
Notes
• Do not include the reserved text GlobalAlarm in a virtual alarm name.
• Creating a virtual alarm that includes itself as a sub-alarm, directly or
indirectly, creates a cyclical dependency. XEdit does not automatically
check for this dependency. Your multiviewer will, however, perform cycle
validation and will record an error in
vroom.log if such a condition is
detected.
