Responsibility Transfer Alert

MSC302(87) requires the use of the "responsibility transfer alert," which functions in
the multiple sensor, multiple equipment installation. When one sensor or one equip-
ment fails but does not disturb the system operation (other sensor or equipment is nor-
mal), the CAM automatically sends the "responsibility transfer alert" (ACN sentence)
to the sensor or equipment that generated the alert.
