Can I interface home automation with the SAI burglar alarm in the By-me control unit?

Yes, the control unit can configure and manage both systems. The control unit will require two BUS lines: the burglar alarm line (known as Area 0 Line 0) where the control unit and the devices of the SAI burglar alarm are installed, and the home automation line (Area 1 Line 0). Communication between the two branches occurs through the 01845 line coupler respecting the terminal connections: BUS1 – burglar alarm line and BUS 2 – home automation line.
