How to Install Wireless Infrared Beam Sensors for Garage Security?

Applications of Infrared Beam Detectors for Garage Doors: Infrared beam detectors (photocell sensor) are typically installed on both sides of the bottom of the garage door. During the door's descent, if the infrared beam is blocked by an object, the door immediately stops falling and rebounds. The core function is to prevent pinching and crushing.

Photocell sensor advantages:

Prevents injury to people, pets, vehicles, and items. When the door closes, if a child, pet, hand, vehicle, or object is in the door's path, blocking the infrared beam, the door immediately stops falling and rebounds, preventing injury to people and damage to cars and items. Garage doors without infrared protection will not detect objects with low resistance and will simply crush them.

Enhances home safety, especially for families with children and pets. Children playing or pets running under the garage door can easily cause accidents. Infrared beam detectors provide passive protection, requiring no manual operation; they activate automatically every time the door is closed, reducing the risk of accidents.

Protects the garage door and its accessories: If a vehicle isn't fully inside the garage, or if boxes, bicycles, or other items are left at the doorway, the infrared sensor will reverse when the door closes, preventing forced closure and avoiding door panel deformation, track damage, and motor overload, thus reducing maintenance costs.

How to correctly install a wireless infrared beam detector?

1. Confirm the motor supports wireless photoelectric: The motor must have a matching wireless receiver module. Motors that don't support it cannot be used with the wireless model.

2. Accessories checklist: Transmitter (TX), Receiver (RX), Wireless receiver (connected to the motor), mounting bracket, screws, battery.

3. Avoid: Direct sunlight, direct headlights, areas subject to frequent vibration, and locations prone to impact.

II. Probe Installation Location (Very Critical)

1. Installation Height: 12-15cm (4.6 inches) from the ground. Do not exceed 20cm. Too high and children may crawl, making detection impossible and posing a safety hazard.

2. Install the transmitter and receiver probes on the inside of the tracks on both sides of the garage door. The door panel, rollers, and tracks must not block the infrared beam throughout the entire closing process.

3. The transmitter and receiver must be at the same height, horizontally aligned, with a deviation of less than 5° in any direction. Do not lock the bracket initially; allow for minor adjustments.

4. Do not use double-sided tape for fixing; the metal bracket must be secured with screws. The vibration from closing the door will dislodge the tape, causing the probe to shift and become ineffective.
