FIELD: guard systems. SUBSTANCE: the following modes of operation are available: complete load, when all the detectors track alarm condition; zero load, when all the detectors are turned off; partial load, when some detectors are turned on; determination of failure in system "breakage in communication line" and determination of damaged part of communication line; determination of failure in system "short circuit" and number of damaged part of communication line; identification of detectors turned off. System has n detectors, n parts of communication line, n switches, n weight converters, unit for changing poles, indication unit and other units, which provide operation of the system in preset modes. EFFECT: improved reliability of guard system. 5 cl, 5 dwg
