A remote control system capable of selectively controlling a desired one of plural devices in response to the transmission of remote control signals from a transmitter. A central control includes a decoder decoding a remote control signal so as to produce a corresponding device control signal, this device control signal being coupled to the plural devices so as to control a desired one thereof in accordance with the decoded signal. The central control includes at least one, and preferably plural, input terminals. Plural receiving elements, spatially separated from each other, are coupled to respective ones of the input terminals, preferably by a conducting lead, and, preferably, a receiving element is provided directly at the central control. The receiving elements are capable of receiving a remote control signal transmitted, for example, by infrared transmission, from the transmitter. A combining circuit, such as an OR-type circuit, in the central control is coupled to the respective input terminals and also to the one receiving element which may be disposed directly at the central control, so as to supply a remote control signal received by any of the receiving elements to the decoder. Hence, a desired device is controlled regardless of the particular receiving element to which the remote control signal is transmitted.
