Alarm Point Indication
•
When an alarm is not active, the background is white with black text indicating Normal and the alarm
indicator light is gray.
•
When any alarm is active, the alarm indicator light turns red, flashes and the text changes to
Unacknowledged.
•
Once acknowledged, the alarm indicator light stops flashing, remains red until the alarm condition goes
away and the text changes to Acknowledged.
•
If the alarm condition goes away (clears) before the operator acknowledges the alarm, the alarm
indicator light will turn yellow and continue to flash until acknowledged. The text will change to
Cleared.
