Abstract: An illumination system includes: a plurality of luminaires; and a controller including a brightness sensor that is used for light intensity control on one or more luminaires among the plurality of luminaires and detects the brightness of the one or more luminaires. The controller divides the plurality of luminaires into a plurality of groups and performs the light intensity control in a first mode or a second mode for each of the plurality of groups. The first mode is a mode in which the light intensity control is performed according to a result of detection by the brightness sensor, and the second mode is a mode in which the light intensity control is performed according to an instruction on a light intensity rate provided from outside.

Abstract: A shell structure of an electrical device includes a first body and a second body. The first body has one or more first lead-out portions, and the second body has one or more second lead-out portions so that electric wires are drawn out. Each of one or more first lead-out portions is formed in the shape of a groove which penetrates a first peripheral wall of the first body and which is opened toward an opening of the first body. Each of the one or more second lead-out portions is formed in the shape of a groove which penetrates a second peripheral wall of the second body and which is opened toward an opening of the second body. The first body and the second body are combined together by allowing the one or more first lead-out portions and the one or more second lead-out portions to overlap with each other.

Abstract: Provided is a time switch capable of allowing a user to readily set up or change a schedule. For this purpose, a chassis 30 of the time switch 10 has same size (i.e., two-row-module size) as that obtained by arranging two three-module sized implanted type wiring devices in two lines along a minor width direction, and installation frame pieces 38 are protruded from both of upper and lower side walls. In addition, each installation frame piece 38 has a long hole 38a for inserting a box screw fastened to the implanted type box (not shown) implanted on the installation surface or a fastener hole combined with a fastener.

Abstract: A setting apparatus for a remote monitoring and control system, which is capable of setting relational data and addresses simultaneously, and is not easily lost. Included is a fixed part that is fixed to an installation surface, and a portable part detachably attached to the fixed part. When the portable part is retained at the fixed part, the portable part can be electrically connected to a signal line, and sets relational data for a transmission controller. When the portable part is separated from the fixed part, the portable part can set addresses corresponding to a switch and a load, with respect to an operation terminal and a control terminal, according to a signal, such as an infrared light transmitted from a light emitting element installed at the portable part. When the addresses are not being set, since the portable part can be retained at the fixed part, the portable part will not be easily lost although a dedicated storage receptacle is not provided.

Abstract: A setting apparatus for a remote monitoring and controlling system allows a decrease in the size of a portable unit. The setting apparatus includes a stationary unit fixed to an installation surface and a portable unit detachably attached to the stationary unit. A battery receiving portion for receiving a battery is protruded backwardly from the rear surface of the portable unit. By receiving the battery receiving portion of the portable unit in a reception concave portion of the stationary unit and engaging a coupling convex portion with a coupling concave portion of the battery receiving portion, the portable unit is detachably attached to the stationary unit. Since the coupling concave portion for coupling to the stationary unit is formed in the battery receiving portion of the portable unit, the portable unit has a decreased size, compared with a case when the portion coupled to the stationary unit is provided independent of the battery receiving portion.

Abstract: Provided is a setting apparatus for remote monitoring and control system, which is capable of setting relational data and address simultaneously, and is hardly being lost. It includes a fixed part 1 fixed to an installation surface, and the portable part 2 detachably attached to the fixed part 1. When the portable part 2 is retained at the fixed part 1, the portable part 2 can be electrically connected to a signal line, and sets relational data for a transmission controller. When the portable part 2 is separated from the fixed part 1, the portable part 2 can set addresses corresponding to a switch and a load, with respect to an operation terminal and a control terminal, according to a signal as an infrared light transmitted from a light emitting element installed at the portable part 2. While the addresses are not being set, since the portable part 2 can be retained at the fixed part 1, the portable part 2 will not be easily lost although a dedicated storage receptacle is not installed.

This control system comprises operation terminals such as switches and control terminals such as relays, and a signal line for connecting a signal transmission unit to the operation and control terminals. Each of the operation and control terminals has an individual address. The transmission unit provides a control signal to the signal line according to a time-division-multiplexing manner such that when one of the operation terminals is operated, a load connected to the control terminal in an address correspondence with the operation terminal can be controlled.

Abstract: In a remote monitoring and controlling system, a selector switch unit sets data for batch controlling and separately controlling operation of illumination loads and transmitting to the signal line a control request signal related to operation for the illumination loads based on the set data. A data memory stores therein set operation states of respective illumination loads and set dimming levels of respective illumination loads so that the operation states and the dimming levels are associated in correspondence therebetween. A control request signal containing the data stored in the data memory is transferred to a terminal unit. The terminal unit transmits a dimming-level instruction signal to its corresponding dimming terminal unit based on a control request signal of dimming level from the selector switch unit, and further transmits a display instruction signal of dimming level to the selector switch unit, thereby displaying a current dimming level.
