System for remote telephone querying and reporting of switching states of appliances and sensors, sends message to caller in correspondence to state of functional part

摘要

System for telephonic reporting of information of electrical functional parts includes a central control unit, one or more stores, a call recognition and a module for carrying out line occupancy, hold and release. The message assigned in correspondence to the state of a functional part (8a-8c) is filed in the stores (2a-2d) and sent to the caller, in which depending on the functional part or the system's state, a number of call signals whose values are filed in a store (3), must be entered before occupancy of the connection line results.
