act of determining whether an Alarmshould not occur

Note 1 to entry: “An Alarm is suppressed when logical criteria are applied to determine that the Alarm should not occur, even though the base Alarm Condition (e.g. Alarm setting exceeded) is present” as defined in EEMUA. In IEC 62682Suppressed Alarms are also described as being “Suppressed by Design”, in that the system is designed with logic to Suppress an Alarm when certain criteria exist. For example, if a process unit is taken off line then low level alarms are Suppressed for all equipment in the off-line unit.
