The centralized monitor & control system includes pairs of link lines which connect, in matrix form, alarm switches, controlled devices, etc., installed at an alarm terminal end. Alarm display devices, starting control switches, etc., are installed at a receiving end in correspondence with the devices at the terminal end. The display devices are adapted to be actuated by the alarm switches or the controlled devices are adapted to be actuated by the control devices. These 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.
