Inactivate - method of the PmAlarmItem object

Alarm item inactivation.
Empty Inactivate([Date tTimeOff])
tTimeOff[optional] (Date) Alarm inactivation time.
If not set, then the computer current time is used.
Calling the Inactivate method over the inactive alarm has no effect. An active alarm is deactivated. The behavior of the alarm during the inactivation is specified in the "Inactivate type" configurator.
If the alarm is deactivated without parameters, then the simplier way can be used by writing the value false into the Active property.
The method is synchronous, it means that it is processed immediately by the alarm subsystem. Nevertheless writing the history to disk is asynchronous, it means that this method passes the request for writing to the history to the alarm subsystem, it is placed into the queue of requests and it is processed later by the alarm subsystem.
