A method for transmitting binary signals having two logical states over a foreign wiring network, in particular for transmitting signals between structural elements of an alarm installation over an electrical supply wiring network. At least one of the two logical states of the binary signals is converted into a particular frequency, provided to the foreign network, and selected on a receiving end by filtering devices. The method includes the steps of recovering the binary signals on the receiving end, and passing the recovered binary signals through first and second differentiating networks which form an interference trap to identify and block interference pulses present in the signal.
