An infrared sensor switch of the invention comprises an infrared sensor with a detection range, and a controller that uses the sensor to try to detect whether or not a person is present in the detection range and controls an ON or OFF state of a corresponding load unit based on each detection result obtained from the sensor. The switch further comprises a sensor block comprising the sensor, and a housing that is mounted in a wall and retains the block so that the center axis of the detection range can be rotated about a horizontal axis and as well as rotated up to at least 40 degrees downward from a forward direction of 0 degrees.

A data setting system for terminal units using an optical wireless signal includes in the respective terminal units a data storing device and a receiving device for the optical wireless signal and, in a data operating device separate from the terminal units, an operating device for preparing and transmitting a setting signal to the terminal units. The setting of data in the respective terminal units employed in a remote supervisory and controlling system using a multiplex data transmission is thereby possible from a remote position from the terminal units through the optical wireless signal.
