ABSTRACT OF THE DISCLOSURE A motor driving a garage door is controlled by a controller, and the rotation of the motor in the normal and reverse directions is normally controlled in response to an actuating signal applied to the controller from a main push button switch. In a specific-mode in which an actuating signal is applied to the controller from an emergency push button switch, a mat switch or a fire sensor, the latter signal has priority over the former signal, and the motor is driven to move the garage door to its full-open position.
