This is an updated version of the product training course introduced by SUPPLY HOUSE TIMES in 1979, authored by Don Arnold.
Some of the first examples of sensor-operated products came in the flush valve field, where the technology was applied to new equipment as well as to retrofit modules (replacing original mechanical actuators with the automatic type). These include both toilet and urinal applications, with model options of either integral or remote sensing (the latter most often mounted into the adjacent wall). The type of power supply usually depends on which of these configurations it is. In the case of the integral type, it is typically battery-powered - with the remote type, hard wiring.
