Keyboard Installation and Operation
Calling Salvos
A
salvo
is the simultaneous display of multiple camera scenes on a group of numeri-
cally contiguous monitors. The number of salvo entries allowed is dependant on the
matrix switching system being used. Each system salvo has a unique identification
number that defines the set of contiguous monitors.
To call a salvo:
1. Enter the identification number of the first (lowest numbered) monitor of the
contiguous monitor group on the alphanumeric keypad. The monitor number
entered will appear next to ENTER on the keyboard's display.
2. Press the MONITOR key.
3. Enter the identification number for the salvo. The number entered will appear next
to ENTER on the keyboard's display.
4. Press the SALVO soft key.
5. The salvo will be displayed on the contiguous set of monitors.
Acknowledging Alarms
When a monitor is armed for an alarm contact, the video input associated with that
alarm contact is displayed on the monitor when the alarm is activated. If the monitor is
armed for manual clearance, any alarm displayed on the monitor can be acknowledged
(cleared) by the operator.
To acknowledge an alarm:
1. Call the monitor that is displaying the alarm video.
2. Press the ALARM ( ) soft key.
If the monitor is sequencing multiple alarms, step through to the appropriate alarmed
video input by first pressing the RUN/HOLD soft key and then by using the CAMERA
FORWARD/BACKWARD key. Press the ALARM soft key to acknowledge the alarm.
Continue to step to and acknowledge each alarm until all the appropriate alarms have
been cleared.
Alarm signalling capability will vary depending on which switching system is connected
to the keyboard. Consult the switching system's documentation to determine the
particulars of the alarm interface.
