ABSTRACT:
In a base station for monitoring the status of several function conditions at remote call boxes, each box of which is assigned a distinctive identification code and is capable of selecting and transmitting a message in the form of a plurality of successive signals upon a change in a function condition, which station includes a message decoder, wherein, upon decoding a given box identification code in a message being processed by the base station, a particular one of a plurality of output selector signals is generated. In response to the coded message being processed, a particular output function corresponding to the call box status is generated. A data transfer device directs the output function signal in parallel to a plurality of output matrices, while a selector/decoder device energizes a selected one of the matrixes in response to the output selector signal, thereby displaying the message processed by the base station at the selected matrix.
