Event Description
The description of an event is used to notify recipients of the event's Alarm/Action of what happened so that they can react accordingly.
Description is the default content of an Action. You can describe the event or situation once in the Description, and reuse the information in all the Actions of the event.
You can also embed user-defined inputs in the Description.
