ABSTRACT A method for transmitting a message by a two way wire connection between a central control and survey station (1) and several remote detection st- ations (3A-3N) adapted to generate a signal represen- tative of at least one parameter of its environment, particularly for the monitoring of buildings, during which the central station (1) suc- cessively generates addresses assigned to each of the remote stations (3A-3N), these latter in response to the reception of this address emitting a message char- acteristic of the value of the corresponding environ- ment parameter, characterized in that said addresses are generated by the central station (1) by modulation of a continuous voltage permanently applied to said telegraphic connection, and in that each remote sta- tion (3A-3N) transmits its message by amplitude modu- lation of the current on said line by application of said voltage to said line.
