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.

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
