Abstract
A sensor for a flushing device having an electric solenoid operated flush valve. The sensor includes a control box, a first radiation emitting source mounted in the control box, a radiation detector adapted to detect reflected radiation from the first radiation emitting source mounted in the control box, a lens cover attached to the control box and adapted to permit radiation to pass therethrough and a control circuit contained within the control box responsive to the sensing unit and connected to the solenoid for initiating operation of the flush valve. The control circuit includes a magnetically activated device for bypassing the sensing unit to initiate operation of the flush valve and deactivate the flush valve for a fixed period of time. Also disclosed is a method of operating the sensor.
