Return-to-normal alarming

When a record that is in alarm returns to a normal state, a return-to-normal alarm is generated to communicate the change in state.

When an alarm condition clears, the system:

• Generates a return-to-normal alarm message.

• Clears the alarm from the alarm summaries after the Controller acknowledges it.

• Spools the return-to-normal alarm message to the event summary.

When the alarm message is generated, it flashes until you acknowledge it. After you acknowledge it, it stops flashing and is deleted from the alarm summary unless the status record has been configured to sustain off-normal alarms. When the record returns to normal, the return-to-normal alarm message appears on your computer and the message begins flashing again. When you acknowledge the alarm, the return-to-normal alarm disappears from the alarm summary.

If the record returns to normal before you acknowledge the alarm, the return-to-normal alarm message is submitted to you and remains flashing until it is acknowledged. Even if the alarm condition clears before the alarm is acknowledged, you must still acknowledge the alarm.

Note: An alarm is not generated if you command a status record to an abnormal state.
