ABSTRACT:
A terminal of a disaster prevention monitor of the present invention detects the power-on of a terminal and sets flag information. When a polling call from a central monitor (receiver) is directed to a terminal after a power-on operation, the terminal transmits an information fetch request signal which requests the receiver enter an initialization routine for initialization of the terminal information. The receiver transmits an information request command signal to the terminal. The terminal transmits information to the receiver identifying the type of terminal which is responding. Depending on the type of terminal, the receiver may command test operations at the terminal and obtain the test results therefrom in order to generate and store proper initialization information about the terminal.
