        C: period (in minutes) during which identical alarms will not be sent. This period cannot be shorter than 10 minutes.

        Recovery Policy

        Condition for clearing an alarm. For example, if this parameter is set to 3, the alarm status will change to "Cleared" if no alarm is generated within 3 minutes.
