Abstract
A garage door operator has a light which is turned on for a preset period by the controller each time the operator motor is operated. A pedestrian door is equipped with a magnetic switch which signals the controller when the door is opened, causing the light to be turned on for the preset period. A switch console has a vacation switch, a work light switch and a push button which, with the magnetic switch, send signals to the controller. Voltage level encoding and decoding is used to minimize the number of connecting wires between the console and the controller. The controller comprises a microprocessor subject to the switch inputs and programmed to produce output signals for operator motor control and light control.
