Abstract

PURPOSE: To correct a malfunction by an artificial error and to improve a guard efficiency by automatically detecting the delay of the transmitting time of respective guard start signals and requesting the retransmission of the guard start signal to an alarm transmitter.
CONSTITUTION: A designating memory 7 for storing the respective guard start designating time ranges of the respective alarm transmitters and to which respective guard start time information is inputted from a receiving signal analyzing part 2 and a semi-alarm generating part 5 for comparing the information of the state of the respective alarm transmitters read from this designating memory 7 with the time data of a clock 6 and for transmitting the terminal number information and the guard start request signal 23 of the alarm transmitter to which the guard start signal does not come at a designated time, are provided. A transmitting data editing part 3 for inputting the terminal number information and the guard start request signal and for transmitting the guard start request signal to the alarm transmitter of the terminal number through a network control part 1, is provided. Thereby, the delay of the guard start signal due to the artificial error is corrected and the guard efficiency can be improved.
