PROBLEM TO BE SOLVED: To collect a temporal change of temperatures at a plurality of points due to a fire in a monitored area as fire history data, and use it for fire analysis of an actual fire.SOLUTION: A monitoring group G1 is formed of an alarm unit 100-1 and a plurality of temperature measurement chips 10-11 to 10-16. When a fire is detected by observed temperature information of any one of the temperature measurement chips 10-11 to 10-16, a fire alarm is outputted and a fire interlocking signal is transmitted to alarm units 100-2, 100-3 of other monitoring groups G2, G3 to cause the alarm units to output a fire alarm. When a fire is detected, the alarm unit 100-1 starts storage control for storing the observed temperature information of the temperature measurement chips 10-11 to 10-16 into a memory as fire history data, and transmits the fire history data to the other alarm units 100-2, 100-3 to back up the fire history data. |
