You can suppress device alarms from several places in the DeltaV system:
For an alarm category (failed, maintenance, advisory), use the alarm's faceplate in the operator application.
For conditions of an alarm category, use the Status/Conditions dialog from the device's context menu.
Because alarms contain multiple conditions, suppressions at the alarm category level will always override suppressions at the condition level.
Example:
A fieldbus device reports that it is due to be calibrated. The Calibration Due condition appears as a Maintenance alarm in the Status/Conditions dialog, the DeltaV alarm banner, and Event Chronicle. Because regular service is scheduled for the following week, the user might choose to suppress all Maintenance alarms from that device using the Details faceplate. Alternatively, the user could choose to suppress only the Calibration Due condition from appearing in the alarm banner and the Event Chronicle by checking the box above the condition in the Status/Conditions dialog for that device. In both cases, the Status/Conditions dialog continues to display the condition as active.
