Abstract
Apparatus and method to adapt a automatic door motor operator utilizing a photoelectric eye generating a digital pulse train of known amplitude, periodicity and duty cycle to a control signal created through the opening or closure of a moving door edge sensing device or strip which closes or opens when compressed. The invention relates to safety edges used on motorized doors to provide a conversion means to allow a sensing edge switch on the leading edge of a moving door to control a door operator control unit which expects to receive a control signal of a predetermined amplitude, period and duty cycle normally generated through use of a photo eye used to monitor obstructions within the path of the moving door. The invention allows field replacement of an obstruction protecting photo-eye sensor with an safety edge switch type device utilizing the existing door operator and the in-place power source.
