ElapsedActiveTimeAlarmExt is available in theAlarm folder of the kitControl palette along with a ChangeOfstateCountAlarmExt extension for COS-based alarms. You can use both extensions to reference the same DiscreteTotalizerExt.

In the parent Boolean point, order the ElapsedActiveTimeAlarmExt slot below the DiscreteTotalizerExt slot that it references. In the ElapsedActiveTimeAlarmExt’s Offnormal container, use the Discrete Totalizer Select property to reference the DiscreteTotalizerExt.

The properties for this extension are the same as those for a standard framework alarm extension. Refer to the Niagara Alarms Guide.
