Alarm Propagation & Operational Modes

Alarms in iControl > Key Concepts > Alarm Operational Modes > Alarm Propagation & Operational Modes

The following cases describe how a system could behave upon activation of an operational mode, depending on the logic table used by the virtual alarm.

Example: Sub-alarm is ‘In maintenance’ (or ‘Offline’), overall status green

The status icon for the sub-alarm will appear in a darker shade and the status will be propagated to the overall (virtual) alarm. The status icon for the overall alarm will be shaded accordingly.

Example: Sub-alarm is ‘In maintenance’ (or ‘Offline’), overall status red

The status icon for the sub-alarm will appear in a darker shade and the status will be propagated to the overall alarm. If there is another red sub-alarm, the overall alarm will stay red. Otherwise, the overall alarm will reflect the state of the sub-alarm that is in maintenance mode.

Example: Overall (virtual) alarm is ‘In maintenance’ (or ‘Offline’)

When an overall alarm is set to maintenance mode, all of its constituent sub-alarms are also set to maintenance mode and their status icons are shaded accordingly.
