 A second major benefit to the Quantum™ opener is Quantum-Gard Wireless photo eyes - another industry advance exclusive to Wayne-Dalton Corp. Normal sensors have wires running from them to the opener's motor. Quantum-Gard photo eyes are wireless, so installation is greatly simplified because the need to drill through walls or run unsightly wiring is eliminated. But these sensors still perform the same important function, which is to transmit an infrared beam across the opening of the garage door. When that beam is broken by a child, a pet, or any object, the closing garage door automatically reverses to the open position.
