d. The unit suspends camera sequencing on the live dis-
play monitor.
8. If the Unit Alarm Out option is selected, the unit ener-
gizes the alarm output associated with camera 16 (see
Alarm Setup in the Intellex Installation Instructions).
The unit remains in the alarm state until ALL of the following
occur:
a. All alarms, including mechanical, are released.
b. The Duration time elapses (see Alarm Setup in the
Intellex Installation Instructions).
Once the unit exits the alarm state, it returns to the previous
display mode, record mode and quality settings.
If the Latch Messages option is selected (see Alarm Setup in
the Intellex Installation Instructions), the unit displays the alarm
message until the Clear Latched button on the Utility Options
screen is clicked (see Utility Options).
Alarm Groups
During normal operation, the Intellex unit samples cameras
in camera number order. Each time through the sequence, the
unit samples one image from each camera (unless disabled).
For example, with nine cameras connected, the sequence is:
12345 6 789 123 ...
When an alarm is detected, the unit increases the number of
samples from the camera associated with the alarm. It adds
the camera to the alarm group. After the unit samples each
nonalarm camera, it samples from all cameras in the alarm
group. As alarms start and stop, cameras are added to and
removed from the alarm group.
For example, if alarms are detected at inputs 5 and 9, the unit
creates an alarm group containing these two cameras. The se-
quence changes as shown below. The group is repeated after
each nonalarm camera.
5 915 925 935 94 ...
