Abstract

In order to increase the interference immunity in danger signal appliances having chain synchronisation, the detectors (M1-Mn) being arranged in the run of a double line (a, b) connected to a control centre (Z), during the transfer of information from one detector to the control centre (Z) the two wires (a, b) of the double line are to be connected through or disconnected symmetrically with respect to said detector. For this purpose, either the switches (S) of all detectors (M1-Mn) are closed, or a switch (S) is provided in each detector in each wire of the double line (a,b), two switches being connected through or disconnected in this way in each case. <IMAGE>
