Touch-free faucets in the home is catching on, and almost any faucet of any design can be activated by a new battery-operated system that is installed beneath the sink. The new system byTechnical Concepts uses Surround Sensor Technology (SST), aninvisible forcethat turns on the water as soon as hands come within a few inches above, below or along either side of the faucet. The water stops when the hands are withdrawn. A mixing valve, positioned under the sink, can be adjusted and set to maintain a fixed water temperature. The SST eliminates handles as well as the sensor eye commonly associated with commercial faucets.
