Abstract
A fire disaster monitoring system of the present invention has a control unit and a fire sensor. The fire sensor includes a sensor base and a sensor body. The sensor base incorporates a first memory which stores first address information of the first memory. The sensor body incorporates a second memory and a CPU therein. The second memory stores second address information of the sensor body. The CPU includes an address reader, a comparator and an address generator. When the power is turned on, the address reader reads the address information in the first memory, and reads the address information in the second memory. The comparator compares the read pieces of address information with each other. When the comparison result by the comparator indicates agreement, the address generator leaves the address information in the second memory as valid data. On the other hand, when the comparison result indicates disagreement, the address generator writes the address information in the first memory into the second memory.
