Notes On Prealarm Rec
• When alarm recordings that have pre-alarms have been
selected, the display will jump to the starting position of the
pre-alarm recordings during the alarm search.
• There are cases where pre-alarm recording cannot be
performed at the specified time if alarm signals are input
immediately after pre-alarm recording has been started.
• There are cases where the alarm's recording time is longer
than actually specified when the time set for this is prior to
the value set for pre-alarm recording.
• The alarm recording parameters for pre-alarm recording
are only activated when recording is suspended.
