METHOD FOR SECURITY AND FIRE PROTECTION OF FACILITIES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC G08B25/08 

FIELD: electricity.

SUBSTANCE: method envisages two-conductor and multiconductor lines usage. In a two-conductor current line for determination of addresses of activated detectors and transducers as well as for the actuating devices group switching on one generates rated current the value whereof conforms with only one activated detector, transducer or switched-on condition of an actuating device. In a multiconductor scheme determination of addresses of activated detectors and transducers as well as the actuating device group switching on are performed by way of current lines commutation for generation of current loops wherein only one activated detector, transducer or actuating device input circuit is simultaneously switched-on. Commutation is performed for current measurement period or for an actuating device switching on period. The device is made as two-conductor and multiconductor; communication current lines therein are placed in the form of mesh and are joined into a rectangular matrix.

EFFECT: protection reliability enhancement and improvement of the device technical-and-operational characteristic.
