SW-D8000U, 16CH. COLOR VIDEO MULTIPLEXER
Timed out alarms are latched for a pre-set time out period from the start of the alarm becoming
active. After expiration of the time out period, the alarm is automatically cleared unless the alarm
input is still active. The time out period is programmable in the menu by the programmer.
If an alarm input is still active after the time out, the alarm will stay active while the input is active,
and then clear immediately that the alarm is inactive. Alarms that cease and restart before the time
out is complete, will restart the time out period.
Timed out alarms can be cleared by the operator at any time. Like latched alarms, if the operator
cancels the alarm, it will be cleared whether the alarm input is still active or not.
cleared by the operator before their inputs have ceased, will not be reactivated until the alarm input
ceases and restarts.
Transparent alarms (Not latched):
Alarms are active only while the alarm input is active. As soon as the alarm-input ceases, the alarm
will be automatically cleared.
NOTE: The operator cannot clear A Transparent alarm. It will remain active as long as the
corresponding alarm input is active.
Application Note:
If it is necessary for the operator to be able to clear active alarms, and Transparent mode is
preferred, then rather select timed-out alarms instead of transparent alarms in the ALARM
LATCHING menu, and set the time out period to 1 second.
ALARM ACTION
The SW-D8000U provides extensive alarm handling capability:
On alarm activation:
q A full-screen image of the camera in alarm will automatically appear on Monitor-B.
q
Monitor-A will automatically switch to pre-programmed quad display for a single alarm. In
addition, a different pre-programmed multi-screen display for multiple, simultaneous alarm
occurrences may be displayed.
q
The programmer can program the unit to automatically freeze the camera-in-alarm at the
instant of alarm.
q Each alarm input can be programmed by the programmer to activate either one or both of
the Alarm Output Relays.
Simple menu tables make it quick and easy for the programmer to select the desired alarm action
for each camera.
Alarm Action Set-Up:
The programmer can program the 'camera in alarm' and three 'associated cameras' which will be
most useful to view with the alarm camera, using the ALARM ACTION section of the ALARMS sub-
menu. This allows the programmer to program any 4 camera numbers. The first camera number
will define the camera in alarm on Monitor-A and Monitor-B.
The factory default for the camera in alarm is the camera having the same number as the alarm
input. (For example, the camera in alarm factory default for alarm input #6 will be camera #6.)
The factory defaults for associated cameras will be the camera before the camera in alarm, plus the
two cameras after the camera in alarm.
