The video loss card provides its own visual and audible alerts. If a video loss card is installed, monitor 16
becomes dedicated to scanning for and reporting video loss conditions. Monitor 16 is no longer available
as a primary, alternate, or spot monitor. Monitor 16 is blank with a green background when there are no
video loss conditions to report. The background turns red when reporting a video loss condition. The red
warning screen displays the first seven camera sites that are reporting video loss. Additional sites
reporting video loss are held in a queue and are displayed on the red screen after alarms associated with
the first seven video loss reports are cleared.
The video loss card has an attached speaker. The speaker (when the audio alarm is enabled) sounds an
audible alert when video loss is detected.
The video loss card also has an
attached relay. When the relay alarm
is enabled and video loss is detected,
the relay closes and provides a
secondary alert through an auxiliary
alarm device (e.g., strobe light or
siren). The auxiliary alarm device is
connected to the terminal strip on the
back of the KTD-440 chassis (see
Figure 21). The relay alarm can also
be used to trigger a recording device.
Note:
The relay is a dry contact.
