Abstract

1. Circuit arrangement for a danger-indicating installation with several indicators (4, 5), which are connected across a two-wire indicating line (2, 3) to a central means having evaluation electronics (20) and which associates the signals supplied by indicators (4, 5) with clearly defined states on the indicators, with a signal level applied to the indicators by the evaluation electronics (20) via indicating line (2, 3) and which is cyclicly keyed, with in each case one counter (43) providing in the indicators (4, 5) and which counts the logic states corresponding to this signal level keying and in the case of identity of the count with an address value in each case preset on each indicator supplies a signal characterizing its state across indicating line (2, 3) to evaluation electronics (20), all the counters (43) being resettable by a resetting signal, characterized in that the resetting signal for the counters (43) of indicators (4, 5) is in the form of a further signal level keying and that the signal characterizing the state, e.g. alarm of fault, of the individual indicator (4, 5) is supplied as a clearly defined, but different signal level to evaluation electronics (20) by the selected indicator (4, 5) within the time interval up to the selection of the next indicator.
