Channel alarm
Each channel has the capability to generate an alarm. An alarm situation is
detected with a basic dual level detector.

Basic single-level alarm. For details see "Basic trigger mode" on

The output of the alarm detector is sent to an alarm line and combined (OR-ed)
with alarm conditions of the other channels and recorders. The result is
available as an external output located on the mainframe controller.
