A centralized monitoring system is described, used for checking the functioning, in particular, of emergency lighting lamps, comprising an electronic control unit (10) connected to the electrical supply mains (30) and a series of peripheral appliances (20, 20A, 20B, 20C, 20D, 20E, 20F), such as emergency lighting lamps, electronic processors, chronothermostats and televisions, which are connected electrically together and receive information and data from said electronic control unit (10). The main characteristic of the system of the invention is that communication between the electronic control unit (10) and the peripheral appliances (20, 20A, 20B, 20C, 20D, 20E, 20F) takes place using carrier digital transmission along the electrical line (90) of the supply mains (30). <IMAGE> |
