Claim:
A method for reception of protection commands in a remote tripping device, in which one or more signals are received, protection commands and combinations of protection commands are coded by means of an individual signal or by means of a predetermined combination of signals, and each protection command is allocated a predetermined minimum safety and/or security value, wherein each signal is allocated a detector which detects the presence of the signal on the basis of at least two different safety and/or security threshold values which can be predetermined, and wherein a protection command is detected if an individual signal, which codes the protection command individually or in conjunction with other protection commands, is detected with a safety and/or security threshold value which is greater than or equal to the minimum safety and/or security value allocated to the protection command, or if all the signals in the predetermined combination of signals which codes the protection command individually or in conjunction with other protection commands are each detected with a safety and/or security threshold value which is greater than or equal to the minimum safety and/or security value allocated to the protection command.
