Garage Door Safety SensorsTo avert any chance of entrapment, a building code regulation was introduced in 1993 that demands all garages with remote door openers, be fitted with external safety sensors. This typically comprises of electronic eyes and sensors fitted on each side of the door frame some four to six inches over the drive surface. The electronic eye works by creating an infrared light beam that extends from one side of the opening to the other. If something or someone breaks the beam, the opener will instantly cut off and the door will stop lowering.
