Alarm Policy

You have the choice of setting the alarm acknowledgment policy on the indicator or on the site. In the Alarm policy area, the default selection is Use the site’s alarm policy. You can choose to have the policy based on the alarm state of the indicator’s most recent reading or that of its most severe unacknowledged alarm: • Most recent reading – Whenever a new reading is processed for an indicator that has an unacknowledged alarm, the alarm state of the indicator is re-evaluated and either raised or lowered depending on the value of the new reading. When this happens, the previous unacknowledged reading is marked as missed and the new reading, assuming it’s an alarm, becomes the reading that requires acknowledgment. In situations where the latest reading is a normal one, the indicator alarm is turned off altogether and no acknowledgment is required. • Most severe unacknowledged alarm – An indicator’s alarm level can only increase in severity as subsequent more severe readings are entered. It will not be turned off or reduced in severity by a subsequent normal or less severe reading. Instead, the alarm remains in effect until all of the unacknowledged alarm readings for the indicator have been explicitly acknowledged. When new readings are entered, previously entered unacknowledged readings are not marked as missed but remain with an acknowledgment status of either “waiting for acknowledgment” or “Re-acknowledgment required”, as the case may be. Note: A subsequent higher-severity reading puts the indicator back in an alarm state and triggers the need for re-acknowledgment even though the work order or work request used to acknowledge the previous reading is still open.
