GENERAL OPERATION
GENERAL OPERATION
OPERATION with 1- 4 Cameras
The SuperQuad HR system can be used with one or two monitors. If
only one monitor is used, it should be connected to the CALL Monitor
output.
The CALL Monitor displays either:
• A Call Sequence, defined at setup (page 10), of full-screen
camera pictures with or without the defined Quad Display.
• An operator-selected, full-screen picture of any camera or
the defined Quad Display.
The QUAD Monitor always displays the defined Quad display.
SUPERQUAD OPERATION - 8 Cameras
Eight camera operation is identical to the four camera operation,
except:
• The Quad Display is defined at setup (page 10) as a
DuoQuad sequence of Quad A and Quad B.
• Cameras 1 thru 4 are displayed in Quad A.
• Cameras 5 thru 8 are displayed in Quad B.
VIDEO LOSS DETECTION
Loss of video at any input is automatically detected by the SuperQuad.
A blinking "VIDEO LOSS" message is displayed in the appropriate
quadrant of the Quad display, and the corresponding quadrant is
blanked. The last picture received before the loss of video is stored in
memory and may be retrieved by pressing the "FREEZE" pushbutton.
ALARM HANDLING
When alarm handling is enabled, the ALARMS pushbutton is
illuminated and the `*' character appears in the bottom center of both
the Call and Quad displays.
When one or more cameras are alarmed:
• The Alarm pushbutton blinks whether or not alarm handling
is enabled.
• The Alarm cameras are identified on the screen by an "A".
• The QUAD Monitor displays either the programmed Quad Display
or a Quad frozen at the first alarm (the frozen Quad is identified on
screen with the message "FROZEN".
Figure 13 - One or More Cameras Alarmed
• The CALL Monitor displays either a full-screen picture of the
alarmed camera, or a sequence of multiple alarmed cameras. Alarm
dwell time is fixed at two seconds. The programmed Quad display
or frozen Quad may be set up to sequence with these full-screen
pictures of alarmed cameras.
Alarm clearance can be set up as one of the following (see ALARMS
setup programming, page 11):
•
Instant (I):
Clears the alarm when the alarm input clears.
•
Delay (D):
Holds alarm for 20 seconds after the alarm input clears.
The Acknowledge button does not override or shorten the 20-second
delay.
•
Acknowledge (A):
Holds the alarm until it is acknowledged by
pressing the ALARMS pushbutton. If more than one alarm is
present, or the Quad display is included in the alarm sequence, the
ALARMS button must be pressed while the alarmed camera to be
cleared is being displayed on the CALL Monitor in the alarm
sequence. This allows the selective clearance of individual alarms as
they are being examined.
When alarms are cleared, the system returns to the operating mode
prior to the alarm. The ALARMS pushbutton flashes to indicate the
presence of an alarm whether or not alarms are enabled.
