Abstract
A centralized monitor and control system includes a plurality of pairs of link lines which connect, in matrix form, a plurality of alarm switches, controlled devices, etc., installed at an alarming terminal end with a plurality of alarm display devices, starting control switches, etc., installed at a receiving end in correspondence with the devices at the terminal end, whereby the display devices adapted to be actuated by the alarm switches or the controlled devices adapted to be actuated by the control devices are operated in response to sequential scanning of the one link lines of the paired link system, thus decreasing the number of the link lines used. The number of the link lines used can be decreased further by effecting the sequential scanning by means of a parallel set of binary coded pulse signals and by connecting the one link line array of the matrix to the alarm switches or the controlled devices and the display devices or the control switches through logical circuits.
