Uses four AA three year life batteries. As user enters the sensor range, the light beam that emits from the sensor is reflected back and transformed into a low voltage electrical signal. Once activated, the circuit continues in a hold mode until the user steps out of range. The operator is then energized and the flushometer is activated. The circuit then resets for the next user.
Water flows until hands are removed or automatic time out is activated.
