Abstract

PURPOSE: To ensure the accurate detection of an alarm signal with an economical constitution, by securing a consecutive connection between an alarm monitor processing part and plural alarm detecting circuit parts including delaying circuits and alarm detecting contacts.
CONSTITUTION: A pulse oscillator OSC of an alarm monitor processing part P oscillates pulses in a certain period at a point A. These pulses propagate consecutively the delaying circuits DELAY of alarm detecting circuit parts S1W Sn. For instance, an alarm is detected at a circuit part Si, and an alarm detecting contact rli closes. Thus the pulse is fed to a delay time receiving circuit of the part P from the part Si. In this case, the difference of time between the pulse delivered from the point A and the pulse reached a point B is equal to the sum of the delay times of the delaying circuits. Then the value of a timer counter is set and held at a count value set register by the pulse reached the point B. In such way, an alarm produced at the part Si can be detected.
