z Use BNC coaxial cable only.
‰ Alarm Input
Before connecting sensors, check driving voltages and output signal types of the sensors.
Since output signal types of the sensors are divided into Open Collector type and
Voltage Output type in general, the wiring must be done properly after considering
those types.
Signal Description
IN COM+ The electric power source to drive input circuit. Connect the (+) wire of electric
power source to drive the Sensors to this port as shown in the above circuit.
IN1 -, IN2 -, IN3 - Connect the outputs of sensors to each port as shown in the above
circuit.
If you want to use Alarm Input, the types of sensors must be selected in OSD menu. The
sensor types are divided into Normal Open and Normal Close. If wrong sensor types are
selected, alarms should be activated reversely to sensor inputs.
~ Normal Open Output Voltage is high state when sensor is activated
~ Normal Close Output Voltage is high state when sensor is not activated
