A system for the remote control of electricity supply to equipment comprises modules (2, 5, 6, 7, 8, 9, 10 and 11) interconnected via electrical wiring (3); some ''equipment'' modules (2, 5, 8 and 9) are connected to equipment (4) to be controlled. A cordless portable controller (1) is used which communicates with the system by transmitting radio, infra-red or ultrasonic signals to modules designated as controlling modules (2) which if necessary relay the signals to other modules via the wiring. Commands from the controller (1), contain addresses which the equipment modules compare with addresses stored therein; these addresses are preprogrammed into stores within the modules using the portable controller (1). |
