Clears an alarm you create using the Set User Defined Alarm VI. If you specify an alarm not created using the Set User Defined Alarm VI, this VI returns an error.

The alarm URL is in the following format: \\computer\process\UserDefinedAlarm. alarm. computer specifies the local computer, because this VI only executes on the local computer. LabVIEW prepends UserDefinedAlarm to the name of the alarm, alarm.
