Abstract (en)

Device for remotely supervising a lighting network comprising a large number of light sources (8, 9, 10, 11, 12). Opposite each light source (8 to 12) is a fibre optic sensor (13) connected to an individual electronic module (14) able to provide information on the address of the said source (8 to 12) and on its state, lit or unlit, the various individual modules (14) being electrically linked with a central station (1) which monitors the whole of the network and which is connected to several intermediate modules (4) each of which is connected up to the individual modules (14) of a branch (6) of the lighting network, with a view to the transmission, to the central station (1), of the address and state information concerning each source (8 to 12). The device according to the invention makes possible the detection of each defective source (8 to 12), with an indication of its address and of the time of the breakdown. <IMAGE>
