Garage door openers manufactured since 1993 must include a safety reversing system, such as photoelectric eyes mounted no higher than six inches above the ground, with a light beam spanning the door opening. The garage door opener is required to reverse the door to the open position if the beam is broken. Other examples of safety reversing systems allowed within the guideline include electric safety edges, which reverse with approximately 15 pounds of downward pressure, and a garage door and opener system without photo eyes, tested together, which reverses upon approximately 15 pounds of pressure.
