  • Patent number: 4153945
    Abstract: A sensor based system, such as a building management system, includes a central processor and an associated subsystem comprising at least a central panel interconnected with a plurality of remote panels, each of the remote panels being capable of further interconnection with a variety of devices for monitoring and control purposes. The subsystem is essentially a digital input/digital output (DI/DO) multiplexer comprising a central panel and from one to fifty remote panels, as an example. A simplified interconnection technique is provided in the subsystem for achieving efficient addressing of the remote panels and their associated sensor devices together with transmission of control and monitoring information. Control signals and status or other indications are handled by manual or computer intervention. Input/Output (I/O) cards are included that provide for all functions required for interfacing the multiplexer subsystem to the individual sensor devices.
