Switch.
2.3.1 Reset Alarm
The alarm can be reset in two ways:
Manual reset:
Resets the alarm whenever the ROTARY wheel is
pressed. The monitor returns to the status before the
alarm occurred.
When the cause of the alarm has not been eliminated,
the monitor continues to display the alarm symbol.
When the ROTARY wheel is not pressed during an
alarm, the monitor automatically acknowledges the
alarm after default 30 secs (programmable range from 5
sec. to 15 min.). The monitor returns to the status before
the alarm occurred. The blinking alarm message is dis-
played until the ROTARY wheel is pressed.
After acknowledging, event replay can be displayed (see
event replay section for more details).
Auto acknowledge:
When there is an alarm, the system automatically
acknowledges the alarm and replays the event (if event
replay is activated) after the programmed alarm dura-
tion has expired (can be set from 5 sec. to 15 min).
Note
If the display is in sequence mode during an alarm, it
automatically returns to sequence mode, starting with
the next image after the alarm image.
2.3.2 Recorded Alarms
When recording in multiplex mode, the system informa-
tion and alarm information are also recorded.
During playback the recorded alarms will be visible.
Should an alarm be received during playback of a tape,
the system will return to live mode.
2.3.3 Special Alarms
A special alarm is given in case of:
• Press the ROTARY wheel to stop the alarm.
Detailed information of the alarm is stored in the history
table.
2.4 DOORBELL OPERATION
If the doorbell button on the intercom box is pressed
the following functions are activated:
• The monitor automatically selects the camera input
to which the intercom box is connected
• The blinking bell symbol is displayed on the monitor
screen as long as the doorbell button is pressed
• The history table is updated and a snap shot of the
camera image is saved (can be recalled for viewing
via the history list)
Remark
The doorbell function is only functional in combination
with an intercom box (option). If ‘remote’ option is
selected, the doorbell can also trigger the alarm output
contact.
2.5 EVENT REPLAY
After an alarm the alarm event replay displays a
number of images before and after the event in a contin-
uous cycle in the top right corner of the screen. You can
turn the Rotary wheel to scroll through the pre-event or
post event images. Pressing the sequence key starts play-
ing the event replay again. When the event is acknowl-
edged, the event replay images will disappear and the
system will return to live mode. This also means that the
event replay images are not saved for further replay.
Note
If auto acknowledge is selected the event replay displays
only one cycle.
2.6 RECORDING/PLAYBACK
Multiplexing
Multiplexing (RECORDING) is when you record the
individual camera pictures in a fast sequence onto a
Video Recorder, instead of just the video from one cam-
era or the video from the Multi-screen generator.
Accordingly, demultiplexing (PLAYBACK) is viewing
the individual pictures of a selected camera from the
tape, and putting them in the right order for you to see.
The benefit of multiplexing is that all information is
being recorded in its original resolution.
Multiplexing also records the system information and
alarm information on the Video Recorder. In this way a
TAMPER An accessory housing has been
opened.
FAIL A failure in the system communica
tion to accessories or camera has
been found.

Bosch Security Systems | 2003 06
V 8394/01T Multiplexer | Operating Manual | Chapter 2 EN | 11
full reconstruction is possible after each event, with
complete freedom to switch between the view modes of
your choice during playback.
Interleave
As indicated, individual pictures from different cameras
are recorded in sequence on tape. (E.g. 1-2-3-4-5-1-2- 3-
4-5 etc.). In case an alarm is triggered for a specific cam-
era, the system will send extra pictures from that camera
to the Video Recorder. (E.g. 1-2-1-3-1-4-1-5-1- 2 etc.)
This alarm mode provides a more frequent refresh rate
and thus the video motion quality. In typical installa-
tions, the monitor alarm output is connected to the
Video Recorder alarm input, causing it to switch to
standard recording mode in alarm, and switching back
to time lapse mode after a certain amount of time. The
multiplex system handles these speed changes automati-
cally, and benefits from the increased Video Recorder
refresh rate.
When switching to playback the Video Recorder
demultiplex symbol will be displayed on screen.
Remark
When using time lapse video recorders, it may take a
while before all individual camera images are read from
tape and can be displayed on the monitor, either in
Multi-screen mode or as a full image. This especially
applies to time lapse settings with long interval times.
One by one you will see the camera images and system
information appearing on the monitor according to the
interval time used. Always use the same speed setting
for playback as for recording.
