PROGRAM A VIDEO LOSS ALARM
Use the Video Loss screen to program the CM6800 to detect video loss from any camera input and indicate the loss through alarm mode – the
logical alarm number, the alarm icon, and a “V” (for video loss) appear on system monitors as specified by alarm group assignment.
Figure 36. Program Video Loss Alarms
1. Select the PHYSICAL INPUT number; the logical camera number associated with the physical input appears in the CAMERA field.
2. Select ON in the ENABLE field.
3. In the GROUP ENABLE field, select “Y” under the appropriate group letter to assign the alarm contact to one or more alarm groups. Refer to
the Program Alarm Groups section for information on alarm group display options.
4. Optional: The ACK TYPE (alarm clearance type) field is set to MANUAL by default, requiring an operator to acknowledge a video loss
alarm from a system keyboard. If you select AUTO, the alarm will time out automatically after the interval specified in the TIME OUT field.
