Alarm Input and Outputs

For alarms, the physical wiring will depend on which alarming equipment is used.
ADTRAN recommends referring to the Alarm Equipment manufacturer's instructions
for alarm wiring.
The shelf currently supports six dedicated alarm outputs and two spare alarm outputs.
The dedicated outputs are Critical Visual (CRI-V), Major Visual (MAJ-V), Minor
Visual (MIN-V), Critical Audible (CRI-A), Major Audible (MAJ-A), and Minor
Audible (MIN-A). Each alarm supports Normally Open or Normally Closed relay
contacts.
Four alarm inputs are supported. They are ACO, Remote, AUX 1, and AUX 2. The
active alarm state is -48 V or contact closure.
Alarm relays are supported by all versions of the SCU and no additional ADTRAN
equipment needs to be provided to utilize the alarming features.
