ALARMS OPERATIONS
LIVE PICTURES MODE ALARM
There are three types of live pictures alarms; the alarms set by an external alarm trigger, the alarms set by a loss of the video signal
and the alarms set by the video sensors.
EXTERNAL ALARMS
Connect external inputs such as a door bell, an interphone, etc.,
to the ALARM IN terminals (1 16). These external switches
will send triggers to the alarm inputs and the alarm display will
be shown in live pictures mode.
Example: If an alarm trigger is received for camera 4
(in multi-display screen)
1 The buzzer is heard and the camera 4 indicator light.
The alarm output changes from HI (5V) to LOW (0V).
2 The image from camera 4 and the camera number (04)
will be displayed on monitor 1, EA (External Alarm) will
flash at the left of the camera number.
The action taken here will depend on the settings entered in
the (ALARM SET) menu (see page 31).
NOTE:
When the alarm operation is over, the display will return to
the mode preceding the alarm trigger.
An alarm trigger can also be received at a terminal for which
a camera is not connected to. In such a case, a grey screen
will be displayed and EA (External Alarm) and the
corresponding number will be displayed.
An alarm trigger can also be received at a terminal for which
a camera is not connected to. In such a case, NO VIDEO
will be displayed, on a grey screen, on the monitor screen.

the settings entered in the (ALARM SET) menu.
During normal monitoring operations the camera select
indicator lights according to the displayed camera. If there is

VIDEO LOSS ALARM
If there is an interruption of the video signal, the buzzer is heard,
and the image just previous to the interruption is frozen
