Abstract

PURPOSE:To prevent a place to be supervised from being left in a non-supervised state by inputting specified information from a supervisory center to a terminal when a supervisory decision means is in a non-operated state and automatically setting a system in a supervisory state. CONSTITUTION:In a normal state, specified transmission/reception of signals is executed between the terminal equipment 1 and the supervisory center. In the middle of the transmission processing, a control part 12 checks the presence or absence of center data meaning fault or disconnection from the supervisory center. When center data is inputted and it shows that there is the fault of a key switch K1, specified data is generated so that an automatic supervisory state does not depend on the switch K1. Since the control part 12 of the terminal equipment can judge to set the system in the automatic supervisory state without depending on the key switch, the non-supervised state from the time when the fault of the key switch is reported to the time when a person in charge is sent is eliminated.
