3-10
Up to ten monitors and eight Video Cassette Recorders (VCRs) can be
designated as alarm monitors and alarm VCrs to view and record the video
at an alarm site. The video outputs for the monitors and VCRs must be in
sequential order such as 1 through 4, 3 through 6, 7 through 10, etc. The
alarm VCRs must be connected to the optional I/O board MX-4248 contact
outputs 1-8. The CCU outputs on/off alarm VCR control data to the HD
switcher on COM 2.
Alarm Monitors
The CCU responds to the alarms in the order they occur. The first alarm is
displayed on the lowest video output programmed as an alarm monitor, the
second alarm is displayed on the next video output programmed as an alarm
monitor. For example, the first alarm monitor is programmed as video output
4 and the last alarm monitor is programmed as video output 6.
Outputs 4, 5, and 6 are alarm monitors. The first alarm is displayed on alarm
monitor 4, and the second alarm is displayed on alarm monitor 5.
If there are more alarms than alarm monitors, the CCU keeps the excess
alarms in a queue. When an alarm monitor becomes available, the CCU
shifts all the alarms so the alarms are displayed on the alarm monitors in
order of occurrence from lowest alarm video switcher output to highest alarm
video switcher output. The oldest alarm from the queue is then displayed on
the highest alarm video switcher output.
If an alarm occurs that is disabled by an
operator at the JPD-100 Controller, the CCU
does not respond. If an alarm occurs that is
not assigned to a MultiCall, the CCU puts the
alarm into the alarm queue and displays it on
the JPD-100 if it is the only alarm.
