METHOD AND APPARATUS FOR PROPERLY SEQUENCED HAND WASHING

摘要

An apparatus and method for controlling plumbing fixtures includes anelectronic control board having a microprocessor that accepts four inputs and produces fouroutputs. Inputs at other than the microprocessor's operating voltage are converted thereto.Outputs having different voltages are controlled by latching relays. The control board can beused with a Smart Sink that requires a sequenced hand washing. The control board can forma node on a network that monitors and controls the functions of multiple boards throughout afacility.
