Shuttle alarms
This operating mode allows switching of between 1 and 4 images per alarm.
Image switching take place on a monitor string of 2 to 12 monitors. The alarm
images move to each monitor in the monitor string in turn, starting from the left-
hand monitor, and are displayed in the same sequence as they are generated.
In other words the first alarm image is switched to the first monitor in the string
first. If a second alarm is triggered, the second alarm image appears on the first
monitor and the first alarm image moves on to the second monitor, etc. The
most recent alarm image is always displayed on the first monitor (alarm master
monitor).
The number of
Pictures per alarm
setting relates to the camera group of the
alarm line where the alarm has been triggered. If the setting were 2 images per
alarm, only the images from the first two cameras in the group would be
displayed, etc. As a camera group contains a maximum of 4 cameras, it is not
possible to switch more than 4 images per alarm.

Alarms in a row
This operating mode functions in the same way as the ‘Shuttle alarms’ mode,
with the following exception: The alarm images are not switched from left to right
to each monitor in turn, but displayed alongside each other in sequence.
So the first alarm image appears on the first monitor in the string, the second
alarm image on the second monitor in the string, etc.
If images from camera groups are to be switched, the leading monitor in the subgroup must be
programmed as the alarm monitor (string and group size but not alarm monitor).

Enable alarm switching:
This option must be selected if it is intended to automatically switch the images
relating to incoming alarms to the monitor in question.
The monitor that has been enabled is displayed in red as an alarm monitor
(see section 12.2)
If you have defined a monitor string, you only need to enable the alarm master monitor.
z
Shuttle alarm:
If a monitor string has been defined and this option has been selected, the most
recent alarm image will be displayed on the first monitor in the string (alarm
master monitor) when an alarm triggers. Any other alarm images on display will
move on to the next monitor in the string one step at a time.
This parameter is only available if more than one monitor has been set in the
Alarm
picture
on
monitor
option.
z
Alarms in a row:
When this option is enabled, the first alarm image is switched to the first monitor
in the string. The second alarm image appears on the second monitor, etc.
This parameter is only available if more than one monitor has been set in the
Alarm
picture
on
monitor
option.
