Claims

[Scope of utility model registration request]

Monitoring in which multiple terminal devices are sequentially called from the center device, each terminal device responds to the call from the center device, sends information on the alarm status of that terminal to the center device, and the center device identifies and displays the response information from the terminals. In addition to installing a spare terminal device with the same functions as each terminal device,
When the response information from a terminal is in an abnormal state such as a fire, the center device stores the terminal determined to be in the abnormal state and the number of abnormal receptions, and calls the next terminal, and repeats the call sequentially to When the number of abnormal receptions reaches a predetermined number, the terminal is switched to a standby terminal, and when the number of abnormal receptions reaches a predetermined number on the standby terminal as well, the standby terminal abnormality determination unit that identifies the abnormal state and the resulting abnormality are activated. An abnormal state determination means for displaying the display and calling the next terminal, and when there is a failure state in which there is no response information from the terminal or there is response information but the data is not normal;
A terminal that is determined to be in a fault state and the number of times the fault has been received are memorized, the next terminal is called, and when the number of fault receptions reaches a predetermined number by sequentially repeating the calls, a fault is displayed for that terminal. A monitoring device comprising: a determining unit; and a standby terminal switching unit that switches an address code of a paging signal between a terminal device and a standby terminal device according to an instruction from a standby terminal abnormality determining unit.
