Alarm Message Latch The ALARM MESSAGE LATCH option determines how long the
ALARM and VIDLOSS (video loss) messages remain on screen. It
toggles as follows:
ON  ALARM messages remain on screen until you press
Function to clear them. Pressing Function removes all video
loss messages and messages for expired alarm events. Messages
for current alarm events remain on screen.
NOTE: If video is not restored before the VIDLOSS message
is cleared, the monitor displays the last image received
until the display format changes, or video is restored.
OFF  Each message remains on screen until the Alarm
Duration time expires (the default is 4 seconds) or the
corresponding alarm event clears.
The default ALARM MESSAGE LATCH setting is OFF.
Video Loss Alarm The VIDEO LOSS ALARM option controls the multiplexer video
loss detection feature. It toggles as follows:
ON  The multiplexer responds to camera video loss as an
alarm event and displays the message VIDLOSS in place of the
cameras picture on both monitors. If ALARM MESSAGE
DISPLAY is set OFF, the message only displays on the call
monitor. The alarm counter counts a video loss as an alarm
for that camera input.
OFF  Camera video loss is not treated as an alarm event,
and a VIDLOSS message is not displayed on either monitor.
The alarm counter does not count the video loss as an alarm.
The only sign of video loss is that the monitor displays the
last image received from that camera until you change the
display format, when a blank window with the camera number
displays. Refer to Video Loss Alarms for more details.
The default video loss setting is ON.
