Claims

[Scope of utility model registration request]

A main operation panel that has a built-in logic circuit of a microcomputer that sequentially sets the address of each terminal device and sends and receives control signals and monitoring signals to and from the terminal device for which the address has been set; a plurality of control terminals that receive control signals from the main operation panel when the address is set by the operation panel and control loads such as subordinate lighting loads based on the control data; and the main operation panel. When the address is set, the switch input terminal returns data about the switch input status as a monitoring signal to the main operation panel during the signal return time, and the monitoring signal from the switch input terminal is used for the main operation. Time-division multiplex transmission control in which control signals are received by the control panel and sent out based on a preset program to be associated with each switch of the switch input terminal and to control each dependent negative cycle of the control terminal. In the device, a daylight sensor is attached to the switch input terminal that provides an oscillation signal if the outside light level is below a certain level as a switch input, and the output terminal of the daylight sensor and the switch input are connected to the switch input terminal. A load control switch of the control terminal is inserted between the switch input terminal of the control terminal and the output of the daylight sensor is cut off when the load control switch is turned off. A time division multiplex transmission control system that is equipped with a timer that provides a main operation panel with control data that turns off the load control switches of all control terminals in the system for a predetermined period in timer mode.
