Abstract (en)
[origin: DE102005062129A1] The system has evaluation units (2, 22) that are formed as freely programmable control units, where the evaluation units have an interface (7) to a building safety bus (3) and another interface (8) for providing high data transmission rate. A data link is established between a building management system (10) and one evaluation unit by series connection with the other evaluation unit over the latter interface. The latter interface has an optical coupler (9) such that the evaluation units are galvanically decoupled from data lines (11, 12) for establishing the data link.
