ALARMS OPERATIONS

There are two types of alarms; the alarms set by an external alarm trigger and the alarms set by a loss of the video signal.

EXTERNAL ALARMS

VIDEO LOSS ALARM

When external inputs such as a door bell, an interphone, etc., are connected to the CONTROL terminal (pins 1 – 4), they will send alarm triggers automatically. On the monitor screen, the alarm display will identify the camera corresponding to the alarm trigger.

Example: If an alarm trigger is received for camera 4 (in 4 divisions split 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 25).
