LED Indicators on the TN2402/TN798 Processor Circuit Pack
NOTE:
If the LED just above the Memory Card Slot is alternating red and amber,
this indicates both card in use and emergency transfer.
Attendant Console LEDs
The console has two red LEDs, labeled ALM and ACK, on the left side of the dial.
The left LED lights steadily when there is a Major or Minor alarm at the switch
cabinet. The right LED lights steadily if the alarm has been successfully reported
to INADS. If the system is unable to report the alarm to INADS, the LED flashes;
signaling the attendant to call INADS and report the alarm.
