Garage Door Safety Sensor – Models GSTBR and STBBL Compatible with most Genie and Overhead Door garage openers manufactured after 1993. These replacement accessories are compatible spare parts, not OEM components. Designed to help keep your garage safe, secure, and compliant with safety standards. Key Features and Benefits: • Broad Compatibility – Works with most Genie and Overhead Door openers built after 1993, making it a reliable replacement option for outdated or damaged sensors. • Proven Safety – The GSTBR and STBBL sensors project an invisible infrared beam across the garage door opening. If the beam is interrupted by a person, pet, or object, the opener automatically reverses to prevent injury or damage. • Protect Loved Ones – Vital for households with children or pets, these sensors help stop accidents before they happen. • Durable Construction – Built to withstand daily use in residential garage environments. • Clear Visual Indicators – Each sensor features a builtin LED to confirm operation: red LED on the sending sensor and green LED on the receiving sensor. How It Works: The sending sensor (GSTBR) emits an invisible beam of light, received by the STBBL sensor on the opposite side of the garage door. When an obstruction blocks the beam, the opener reverses the door's movement automatically. This safety system reduces the risk of injury to people and animals and protects vehicles and belongings from potential damage. Quick and Easy Installation: • Includes stepbystep user manual for swift installation. • Requires only a basic screwdriver. • Installation Tip – Ensure the opener is disconnected from power before beginning work. • All mounting hardware provided; wiring not included. Package Contents: • 1 Sending Sensor with bracket (red LED) • 1 Receiving Sensor with bracket (green LED) • 4 Wingnuts • 4 Round Head Bolts • 1 User manual (Note: Wire is not included in this kit) Practical Applications: 1. Home Garage Safety – Prevent accidents during daily use, especially in households with children playing nearby. 2. Pet Protection – Avoid harm to pets that may wander under the garage door unexpectedly. 3. Vehicle and Property Protection – Stop the door from closing on parked cars, bicycles, or stored equipment. Models GSTBR and STBBL offer dependable safety performance in a simple, easytoinstall package, helping keep your garage secure and compliant for years to come.
