Number of alarm tracks
CAUTION!
!
Alarm tracks must be set up in the required partition for alarm recording.
The unit uses a special recording mode during alarm recording for optimal usage of storage
capacity: as soon as a time gap for alarm recording begins, a recording is continuously made
on one segment, which is the size of a complete alarm sequence (pre- and post-alarm time).
This segment in the partition functions in a similar manner to a ring buffer and is overwritten
until an alarm is actually triggered. Recording occurs on the segment only for the duration of
the preset post-alarm time and a new segment is subsequently used in the same manner.
Select the number of alarm tracks to be used in the partition. One alarm event can be
recorded in each alarm track. Accordingly, the number of alarms entered can be recorded and
archived. A partition can contain a maximum of 128 alarm recordings.
If the Ring mode option is set for the partition, the latest alarm recordings are always saved in
the preset number. If the Linear mode option is selected for the partition, the recording is
stopped as soon as the total number of alarm tracks has been recorded.
