Sloan OPTIMA® equipped Flushometers provide the ultimate in
sanitary protection and automatic operation. There are no handles
to trip or buttons to push. The Flushometer operates by means of an
infrared sensor that adapts to its surrounding. Once the user enters
the sensor’s effective range and then steps away, the Flushometer
Solenoid initiates the flushing cycle to flush the fixture.
