14.7.2 External Control Output
Note When you provision an external alarm, the alarm object is ENV-IN-nn. The variable nn refers to
the external alarm’s number, regardless of the name you assign.
14.7.2 External Control Output
You can provision each alarm output separately. Provisionable characteristics of alarm outputs include:
• Control type
• Trigger type (alarm or virtual wire)
• Description for CTC display
• Closure setting (manually or by trigger). If you provision the output closure to be triggered, the
following characteristics can be used as triggers:
– Local NE alarm severity—A chosen alarm severity (for example, Major) and any
higher-severity alarm (in this case, Critical) causes output closure.
– Remote NE alarm severity—Similar to local NE alarm severity trigger setting, but applies to
remote alarms.
– Virtual wire entities—You can provision an alarm that is input to a virtual wire to trigger an
external control output.
