<p>In a luminaire load control system control signals are converted into power line carrier communication signals which are transmitted through branch power lines (1a, 1b) to terminal units (3) for controlling a plurality of loads (2), in particular luminaire loads, without causing any significant interference to power line installation. The conversion of the control signals is done respectively at a plurality of gate way units (8a, 8b) mounted on each branch power line (1a, 1b). Each gate way unit (8a, 8b) includes a memory unit for storing the information regarding the connecting status of the terminal unit (3) for sending back the stored information to a central control unit (4) upon receipt of a send-back command therefrom.</p> |
