HOME SIGNALLING SYSTEM WITH DOUBLE-WIRE CONNECTION OF USER Russian patent published in 2008 - IPC H04M11/02 H04M1/02 

FIELD: physics.

SUBSTANCE: said utility invention relates to a home signalling system having at least one door unit and at least one flat unit. At least, the flat unit/each flat unit is connected or provides for the connection using a double-wire circuit for the transmission of control and/or communication signals, as well as the power supply voltage. At least one section of the available door and/or flat unit has a modular design, each modular unit consisting of at least two modules (M), which are connected or provided for the connection to each other via an internal bus. One of the modules (M) forms a bus connection device in the form of a link between the external double-wire circuit and the internal bus. The internal bus consists of at least three conductors, namely, of a grounding bus (GND), one system bus (EXTBUS) leading further, together with the grounding bus (GND), external double-wire circuit (6), and a data communication bus (COMBUS) serving, together with the grounding bus (GND), for the communication between the microcontrollers (mcC) of individual modules (M).

EFFECT: simplification of connection of enhanced components.
