The Garage Door Safety Reversal Mechanism in Focus
It was in 1993 when safety reversal mechanisms became a requirement in garage doors. The automatic garage door opener was not originally equipped with this extra safety measure. But because of accidents, garage door company standardswere made better and upgraded to include these sensors. These safety modifications were placed approximately six inches from the floor. A sensor is placed by the garage door service technician on either side of the door. The main function of the safety reversal mechanism is to stop and reverse the door's downward trajectory when an object makes contact with the light beam that runs across the width of the door, from one sensor to the other. Any obstruction, whether an object or a person that breaks the light beam as the door is closing down is then safe from the crushing weight. garage opener service is the least of your problems without a mechanism to facilitate this function.
