For the operation of the unit it must be installed in a special complementary box in which a separate supply unit and a battery are installed. The small size and weight of the unit, the sufficient output power of the transmitter, the small consumption and easy servicing make it excellent to use in remote control systems.

Its operation is organized in the following way - the signals from sensors or alarm stations registered and encoded by a digital encoder are transmitted via RS232 to НМ18 /peripheral module/. These signals are transmitted via a communication protocol with confirmation of the received data. The signals are received by НМ18 /central module/, passed on to a digital encoder for transmission via a radio channel or a cable to equipment furnished with the relevant decoder unit.
