摘要： 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.

摘要： A disaster prevention monitor is disclosed in which the power consumption during a line monitoring process is reduced, and a disconnection or a short circuit of control lines can be detected by using a single switching means. A central station has a monitor command transmitter for transmitting a monitor command signal to initiate monitoring of power and control lines. A terminal or repeater station has circuitry for controlling the connection of control lines between a line monitor and power lines. During normal conditions, the control lines are not connected to the power lines, but become so connected only in response to a command from the central station. A line monitoring command causes generation of a negative voltage which is applied to line monitoring circuitry to actuate such circuitry for monitoring the status of the power and control lines.
