The manufacturer usually provides a diagram to help with proper placement, which you should refer to.
Finding the Correct Position
Correct positioning is crucial for the sensors to function properly. The sensors need to be mounted at a height between 4 to 6 inches from the ground. This height allows them to effectively reach the average size of an object or person while remaining unobstructed. If positioned too high or too low, they may not detect obstructions effectively.
Securing the Sensors in Place
Once you’ve verified their position is correct, secure the sensors using screws to the mounting brackets. Ensure they are tight enough to hold but not overly tight, which could risk damaging the sensors. It’s a good practice to double-check the alignment before fully securing them. Those small adjustments can make a big difference in performance.
Step 4: Connecting Wires and Finalizing Installation
The final step in your installation process is connecting the wires. Follow the wiring diagram included with your new safety sensors to properly connect them to the garage door opener. Typically, this involves connecting wires from each sensor to the terminals marked for safety sensors on the opener.
