Abstract

PURPOSE:To achieve the monitor control of mulit-item, by transmitting power supply and monitor controlling clock pulse and also monitor control state switching pulse via two transmission lines between the center side and terminal device side of an overall accident prevention system. CONSTITUTION:The center sideIand the terminal device side II are connected via transmission lines l1 and l'1, and power is given to the terminal device II with a power supply voltage drive circuit 1. At monitoring, the pulse of a clock pulse drive circuit 2 is switched according to the state of monitored objective group 22 and it is monitored at an amplifier at the center sideI. At control object selection, a selection pulse from the circuit 2 is counted 13 to select the objective of a controlled objective group 21, and switching of electric circuit at the terminal device side II from monitoring to control objective selection is made by transmitting the clock pulse having high and low level period of a long period from the circuit 2, they are discriminated at discrimination circuits 16, 17 for switching.
