Office Alarm Test
Description
This test verifies proper operation and wiring of the office alarms in a network
equipment building system (NEBS) (central office) environment.
NOTE:
Perform this test on all shelves where office alarms are connected.
NOTE:
After completing the office alarm test, disconnect the DDM-2000 OC-12 office
alarms from the office alarm system. This will prevent the office alarms from
being activated while performing the other tests in this section.
NOTE:
It is a requirement that alarms on the DDM-2000 OC-12 do not affect and are not
affected by other equipment via office alarm connections. During this test, exam-
ine the alarm state of other equipment connected to the same office alarms as
the DDM-2000 OC-12 after creating or clearing every alarm.
NOTE:
Prior to and after completing this test, verify the DDM-2000 OC-12 is clear, of all
alarms (that is, only green LEDs are lighted). If alarms do not clear refer to the
"Troubleshooting" section of this manual.
