To wire a sensor for a Genie garage door, follow these steps:
1. Identify the sensor wires: one will be black and the other white.
2. Locate the terminals on the back of the garage door opener.
3. Connect the black wire to the terminal labeled “black” or “line.”
4. Connect the white wire to the terminal labeled “white” or “neutral.”
5. Make sure the wires are securely connected and not touching each other.
6. Test the sensor by closing the garage door and ensuring it reverses when an object is in its path.
By following these steps, you can successfully wire a sensor for a Genie garage door.
Genie garage door openers are equipped with a photo-electric sensor system that helps prevent damage to the door or opener. This sensor emits an infrared beam, and if the beam is broken, the opener will stop closing the door and reverse the movement to open it again. The process of wiring a sensor for a Genie garage door opener is similar to wiring any other opener. However, Genie uses clips to secure the wires to the opener rail instead of stapling them to the ceiling.
Step 1
Start by unrolling the low-voltage wires on both sides of the door, starting from the sensor and going back towards the Genie power head. Each low-voltage wire consists of two strands enclosed in wire insulation.
Step 2
Use staples to attach the wire to the wall, positioning them 6 inches above the sensor. Make sure to leave 3 inches of the wire hanging past the sensor. Before hammering the staple into the wall, ensure that the wire is centered inside the insulated staple. Be careful not to pierce or mash the wire with the staple; the staple simply needs to hold the wire in place.
Step 3
Stretch the wire up the wall until you reach the top corner of the opening. Secure the wire with a staple and stretch it over to the point where the opener rail connects to the top of the garage door. Use a staple to secure the wire to the wall. Repeat this process for the opposite side.
Step 4
Place the wire on top of the solid sides of the opener rail. Slide a wire clip over the wires and rail at the front of the rail. These wire clips are angled plastic pieces that fit tightly over the top of the opener rail. Stretch the wires halfway across the top of the rail and attach another wire clip. Continue stretching the wire over the top of the opener and place another wire clip 4 inches from the end of the rail. Evenly distribute additional wire clips across the top of the rail between the existing ones.
Step 5
Using a utility knife, separate the two strands at the end of the wire near the sensor. Carefully slide the blade between the two strands and separate the last 2 inches of the wire.
Step 6
Strip 1/2 inch of insulation from each wire using wire strippers. Loosen the two wire terminal screws on the sensor by turning them one full turn with a Phillips-head screwdriver. Insert each wire end between the flat plate under the screws, and tighten the screws to secure the wires. Repeat this process for the other side.
Step 7
Place a step ladder under the rear of the Genie door opener power head. Unplug the power cord from the ceiling outlet. Locate the terminal screws on the back of the opener head.
Step 8
Loosen the second and third terminal screws from the top by turning them one full turn with the screwdriver. Use wire strippers to cut off the excess ends of the wires, leaving only 6 inches of wire hanging over the opener power head. Separate the ends of the wires, just as you did at the sensors, and strip off 1/2 inch of insulation from each wire.
Step 9
Shape the ends of the wire into tiny loops. Insert the two wires with the black stripe onto one of the terminal screws and secure the screw. Insert the other two solid white wires onto the remaining terminal screw and secure the screw. Connect the power cord of the opener to the ceiling outlet.
