FIELD: electrical engineering.
SUBSTANCE: proposed device can be used in low-voltage lines of 220 V to organize communication channel at frequencies ranging between 13 and 23 kHz included in remote burglar alarm communication system for objects, such as suburban plots of land, garages, shops, and the like, where means for telephone and radio communication with home affairs agency are not available.
EFFECT: enhanced signal transfer speed.
