The door will close only when holding down the button the voltage at the operator unit at the sensor wire connectors with the wires removed is about 1 1 2 volts. The sensors are located above the floor at each side of the door opening and generate a low voltage beam that completes the electrical circuit when the door is activated. The output voltage for the door sensors should be between 5 6 volts dc. If an object or person is in the way of the beam the closing door reverses direction.

One that sends an infrared beam and one that receives the beam. The wired controller and sensors use low voltage wiring usually 24v to connect to the motor unit.
