A control system includes a load including an operative part, and a control device for supplying AC power to the load through a power line and operating the operative part. The control device includes an interruption mechanism and a transmission mechanism. The load includes a controller. The transmission mechanism transmits a predetermined control signal to the load through the power line by blocking the power supply to the load by the interruption mechanism for a time duration shorter than a half cycle of AC output. The controller controls the operative part based on the control signal received from the control device.

Control system for controlling a load via power-line communications

A security-ensuring apparatus having an actuating unit for the initial actuation thereof, an alarm-mode selecting unit for selecting a desired alarm mode set in the apparatus, a separate or built-in emergency-detecting unit for detecting an emergency or an abnormality in a predetermined protected area in which the apparatus is arranged to ensure security, and a display unit for displaying diverse kinds of information regarding security, including information on the operating procedures thereof. The display unit comprises a visual displayer and/or an acoustic displayer and is accommodated in the casing of the security-ensuring apparatus.
