Explanations

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.
