System and method for converting manually operated flush valves

摘要

A conversion system for converting an installed manually-operated flush valve used with a urinal or toilet is designed for automatic operation. The conversion system includes a power module, a control module, a driver module coupled to the manually-operated flush valve, and an optical sensor constructed to detect light arriving from a detection field. The control module is constructed to control activation of the driver module based on a signal from the optical sensor.
