Attendant Console LEDs
The console has two red LEDs, labeled “ALM” and “ACK.” The ALM LED lights
steadily when there is a major or minor alarm at the switch cabinet. The ACK LED
lights steadily if the alarm has been successfully reported. If the system is unable
to report the alarm, the LED flashes; this signals the attendant to call the Avaya
alarm receiving system and report the alarm.
