Interaction between suppression types

The combination of alarm suppression types does not affect the performance of each type. An alarm is suppressed when it satisfies one of the suppression criteria.

The following illustrates the interaction of the different suppression types:

• The alarm hold-off timer prevents a record from going into alarm. The alarms for any child records of that record that are specified for parent alarming or transient alarm suppression are also suppressed.

• The child of a record that is specified for parent alarming goes into alarm. If the alarm is suppressed, the child suppresses alarming for any of its children that are configured for parent alarm suppression.

• A record’s alarm is reevaluated when a suppression timer (for example, parent alarm timer) expires. At this point, the system evaluates any suppression criteria before generating an alarm.
