alarm has been cleared. When the short signal option is active the alarm signal
will shut off automatically.

Alarm image behaviour
z
After alarm reset
After an alarm has been cleared, two different parameters can be set using the
switch:
The alarm image display is maintained after the alarm reset
The pre-alarm image is switched after alarm reset
, i.e. the image that was
switched before the alarm was triggered, is switched back to the display.
z
Alarm images can / cannot be manually overwritten
The switch allows two different parameter settings:
Alarm images cannot be overwritten
Manual switching has no effect on this monitor.
Alarm images can be overwritten manually
The alarm image is overwritten by a manually switched image, thus clearing the
alarm
z
Update alarm picture when stack alarm is active:
If this option has been selected, the current alarm image will be continually
displayed if Stack alarm is active.
If this option has not been selected, the alarm image will remain on display until
the alarm has been cleared. Only then will the next alarm image in the stack be
presented on the alarm monitor.
