A remote error signalling system, in particular for non-serviced wireless transmission stations, with two identical regenerators composed of a shaping amplifier, filter and linear amplifier connected in a chain, characterized in that regenerators' filter and linear amplifier have an analogue key (K) built in between them, the output of the filter of the first regenerator is additionally connected to the input of the analogue key (S), to the first input of a timing unit (UT) and to the input of a start system (US), the output of which is connected to the second input of the timing unit, while the timing unit is connected via its first output to the control input of the analogue key (S), via its second output to the control inputs of the analogue keys (K) which are connected in parallel, and via the third, which is a parallel bus bar, to the address input of an analogue multiplexer (M), which has the frame connected in series through condensers (C1-Cn) and keys (A1-An) to its multiplexed inputs, while the output is connected to the input of the line amplifier (WL) of the second regenerator and through the resistor (R) to the output of the analogue key (S).<IMAGE>
