Alarm Settings – Reporting
In the Alarm Settings dialog box, use the Reporting tab to define a tolerance range and trigger frequency for
condition or state triggers. Reporting further restricts when the trigger occurs.
Procedure
1 If necessary, display the Reporting tab of the Alarm Settings dialog box.
a Display the object in the Inventory panel.
b Select the object and press Ctrl-M to open the Alarm Settings dialog box.
c Click the Reporting tab.
2 Enter a Tolerance.
A 0 value triggers and clears the alarm at the threshold point you configured. A non-zero value triggers
the alarm only after the condition reaches an additional percentage above or below the threshold point.
Condition threshold + Reporting Tolerance = trigger alarm
Tolerance values ensure you do not transition alarm states based on false changes in a condition.
3 Select a Frequency.
The frequency sets the time period during which a triggered alarm is not reported again. When the time
period has elapsed, the alarm will report again if the condition or state is still true.
4 Click OK.
Managing Alarms
You can change alarms, disable alarms, reset alarms, and acknowledge triggered alarms. In addition, you can
export a list of alarms to a file.

Acknowledge Triggered Alarms
Acknowledging a triggered alarm suppresses the alarm actions from occurring. It does not reset the alarm to
a normal state.
