In a typical scenario, a technician might want to effect repairs on a device in the path of a
signal being monitored by iControl. Before beginning, the technician would manually set the
corresponding alarms to In Maintenance mode, to avoid having iControl report a sudden flood
of errors. Once the repairs are done, the technician would then manually take the alarms out
of In Maintenance mode, putting them back online, but the alarm latches would not be
automatically reset. In this mode, alarm transitions affect the latch and the acknowledgement
states of alarms. See
Inverted
The Inverted mode is used to configure a GSM to publish the inverted value of a specific
alarm’s state rather than its actual state. This is useful when one would like to report an error
condition when an alarm would normally not be in error, and a normal condition when it
would normally be in error. An inversion action can be configured manually (you invert the
alarm and it remains inverted until you turn off the inversion mode) or by scheduling an
inversion for a specific time and duration. If you would like to schedule an alarm inversion, you
can report certain error conditions during certain periods of the day and the exact opposite
during other periods of the day. For example, you may want a video freeze condition while on-
air during the day to be reported. But during the night, if there is a movie being broadcast by
accident, you may want for this condition to be reported as well.
Like the Offline and In Maintenance operational modes, the Inverted mode is Boolean (that is,
the Inverted mode can be either On or Off). A primitive alarm’s Inverted mode (On or Off) is
propagated up to parent virtual alarms’ Inverted modes.
You can switch an alarm’s Inverted mode to On or Off either manually or by scheduling. A
manual switch is operator-driven and causes a mode change instantaneously. A scheduled
switch is preconfigured by an operator to occur at a preset time and frequency.
Snooze
When dealing with unscheduled events, operators sometimes need the ability to quickly
suppress alarms for a certain period. The Snooze operational mode allows you to turn off an
alarm temporarily, either for one of the preset durations (see
) or until a later time
of your own choosing (see
IMPORTANT: System behavior
You cannot directly edit the Inverted mode of a virtual alarm or alarm folder; you
can only change a virtual alarm’s Inverted mode indirectly: by changing the
Inverted mode of one or more of its primitive alarms.
