1. Switches to FULL if 1 alarm is present. If multiple alarms are present, an alarm sequence starts with a dwell
time of 2 seconds. The sequence views (either FULL or QUAD) matches the user-programmed values in the
ALARM OPTIONS menu. The unit always returns to the view mode it was in prior to alarm event upon expiry of
the alarm event.
2. REC output follows the VIEW operation if the REC OUT MODE is set to SAME AS MONITOR otherwise it
remains in Quad mode. This option includes the operation described for MLUTIPLE ALARMS.
In addition to the functions above, you can enable alarm relays, trigger outputs, and the
beeper sound.
For example, CAM 1 and 3 are set to FULL and CAM 2 and 4 are set to QUAD and all 4 cameras
are in ALARM. The video processor displays the video images in this sequence:
CAM 1 FULL, QUAD, CAM 3 FULL, QUAD, CAM 1 FULL... until the alarm inputs are cleared.
