Abstract: The system has at least one movement indicator (1) which controls, by wireless communication, an actuator (8) for controlling a light (9). On detection of movement, a command signal is generated to control the light, although there is also data transmission between the indicator and the actuator without previously detecting movement. A status telegram is generated by the movement indicator and sent to the actuator. If there is no command signal or status telegram within a predetermined period of time, this is interpreted as a function fault and is displayed by the actuator.
