Multi-Condition Alarm

With this feature, it's possible to configure alarms with multiple alarm conditions separated by conditional operators, AND and OR. If the equation will evaluate to true, then the alarm will be triggered. 

  1. To set up a new multi-condition alarm select Setup -> Custom Alarm and select the plus icon on the top right corner of the screen.

  2. Click the Multi Condition checkbox in the upper right corner, this will change the view in the browser window.
  3. Now click the plus icon in the center of the screen which will add a new condition.


  4. When a condition has been created it's possible to select a variable by clicking the "Select Variable" button on the condition, which will open the default VDV Variable Selector. It's also possible to change the arithmetic operators by clicking the operator, available operators are <, =, >. Finally, adjust the alarm limit for that condition before creating a new one.

  5. Add a new alarm condition by clicking on the plus button again or when hovering over a condition two more plus button will appear on the left and right side of that condition. By clicking on either of those a new alarm condition will be added before or after that condition. Using this method allows conditions to be added in-between a large set of conditions.
  6. When the second condition has been added a conditional operator is separating the two conditions. Simply click the operator (default AND) to change it.

  7. Repeat steps 3 through 6 to add all the conditions needed for the alarm.

  8. To remove a condition from the alarm Ctrl-Click the condition (it will change to color green) and click the button with the trash bin and that will remove the selected condition. One or more conditions can be removed at once.
