ALARM INPUT CONNECTION
Sensor Input
Before connecting sensors, check the sensor driver voltage and output signal type. Since sensor output signal types are divided into
Open Collector and Voltage Output types in general, the cabling must be installed properly depending on the signal type.
Signal Description
IN COM+ Connect (+) cable of electric power source for Sensors to this port as shown in the circuit above.
IN1 −, IN2−, IN3−, IN4− Connect output of sensors for each port as shown in the circuit above.
