Note: ID numbers of all sensors/actuators are available on the Peripherals page.
5) Select "State Sensor/Actuator" because the contact closure sensor is a state sensor.
6) Select "Alarmed" since we want the PRO4X to respond when the selected contact closure sensor
changes its state related to the "alarmed" state.
7) In the 'Trigger condition' field, select the Alarmed/Open/On radio button so that the action is taken
only when the contact closure sensor enters the alarmed state.
8) Select "Activate Load Shedding" from the 'Available actions' list.
A Note about Infinite Loop
You should avoid building an infinite loop when creating event rules.
The infinite loop refers to a condition where the PRO4X keeps busy because the action or one of the
actions taken for a certain event triggers an identical or similar event which will result in an action
triggering one more event.

Example 1

messages.
