Alarm Card Troubleshooting

6. Verify the amphenol cable is connected correctly to the Alarm card. At a
cross-connection point between the Alarm card and the external equipment, open the
circuit under test. Connect a short across the Alarm card sensor input in question. A
SENSOR alarm should be reported. If no alarm is reported, the sensor port may be
defective.

7. If the Alarm card is determined to be faulty, replace it and return the faulty unit for
repair to the location specified by your distributor.

Note:

Refer to the Alarm Card Filters table located in the System Configuration and
Operation Chapter of the System Reference Manual.
