Abstract: 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.

Abstract: A monitoring and control device for use in a remote monitoring and control system includes a display unit provided with a screen for displaying operation buttons mated with the loads, an operation input unit operable by a user, the operation input unit including a touch switch panel superimposed on the screen of the display unit and a control unit for performing display control of the display unit and load control in response to the operation of the operation input unit. The control unit includes a display control unit for causing the display unit to display one operation page selected from a plurality of operation pages containing different combinations of operation buttons and a page changeover unit for changing over the operation page displayed on the display unit in response to a user's operation.

Abstract: 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 exists in the detection range and controls on and off of a corresponding load unit based on each detection result obtained from the sensor. The switch further comprises a sensor block provided with the sensor, and a housing that is put in a wall and retains the block so that the center axis of the detection range can be rotated about a horizontal axis and rotated up to at least 40 degrees downward from a forward direction of 0 degree.

Abstract: A control terminal 32 includes an individual address setting section 12 for setting a unique individual address, and a simultaneous control address setting section 13 for setting a simultaneous control address common to the plurality of control terminals 32. A simultaneous control address is commonly assigned to the control terminals 32 to be subjected to group control. When an UP switch Sb or a DOWN switch Sc of an operation terminal 31b for group dimming purpose is pushed, a transfer signal including the simultaneous control address is transmitted to a signal line Ls from a transfer controller 30. The respective control terminals 32 substantially simultaneously receive the transfer signal, thereby changing the intensity of illumination loads.
