Offered by Family Garage Door Repair of Charlotte, NC
At Family Garage Door Repair of Charlotte, NC, we understand that safety is a non-negotiable part of every garage door system. That’s why we offer the reliable and durable IR Safety Sensors w/Brackets 820CB. These infrared safety sensors are a critical component in protecting your family, pets, and property by automatically stopping or reversing your garage door if something crosses the path of the invisible safety beam.
The 820CB uses an invisible infrared beam that spans the width of your garage door opening. When something disrupts this beam during door operation, such as a person, vehicle, or object, the system sends a signal to immediately stop or reverse the door, preventing injuries or damage.
Each unit comes with heavy-duty brackets for fast, secure installation. The included brackets ensure the sensors remain firmly in place and properly aligned for consistent performance.
Troubleshooting is made easy with built-in LED lights that indicate alignment. A steady light confirms proper setup, while a blinking light warns of misalignment or obstruction.
Engineered for garage environments, these sensors are built to withstand heat, cold, moisture, and dust, ensuring long-lasting operation in residential settings.
