Garage door safety has become an essential part of modern home security. Among the trusted solutions, the Gstb-Bx Genie Garage Door Opener Safety Beam Sensors 27220R stand out as one of the most reliable accessories for Genie garage door systems. These sensors are designed to protect people, pets, and property by ensuring that the garage door reverses automatically if an object or person interrupts the invisible safety beam.
If you are planning to replace your old sensors, install new ones, or troubleshoot an existing issue, this comprehensive guide will walk you through everything you need to know about the Gstb-Bx Genie Garage Door Opener Safety Beam Sensors 27220R.
What Are Gstb-Bx Genie Garage Door Opener Safety Beam Sensors 27220R?
The Gstb-Bx Genie Garage Door Opener Safety Beam Sensors 27220R are photoelectric safety devices that work as a pair to create an invisible beam across the base of your garage door opening. One sensor emits an infrared beam, while the other receives it.
If the beam is interrupted—whether by a car tire, a pet, or a child—the sensors send a signal to the garage door opener to stop closing and reverse direction. This system is a mandatory safety feature for all garage doors manufactured after 1993, making the sensors a crucial part of your Genie system.
Why Are They Important?
Safety beam sensors are more than just an optional accessory; they are required for compliance with U.S. federal safety regulations. The Gstb-Bx Genie Garage Door Opener Safety Beam Sensors 27220R ensure:
- Accident Prevention – Stops the door from closing on people, pets, or belongings.
- Property Protection – Prevents damage to vehicles parked too close to the closing door.

- Peace of Mind – Ensures reliable operation every time you use your Genie garage door opener.
Without properly functioning sensors, your garage door system may not close at all—or worse, it could pose a safety hazard.
