When an alarm is first registered, it appears on the alarm display and is highlighted in yellow. If the
alarm is short term (that is, two seconds or less), the alarm text is not highlighted after approximately
two seconds. If the alarm continues longer than two seconds, the text remains yellow and the alarm
duration is incremented. When the next alarm occurs, the previous alarm moves down one position.
The CMN-91 unit has enough memory for 100 alarms per input. When 100 different alarm events have
occurred, alarm number 100 is dropped and the most recent alarm is tagged as 01.
