PROBLEM TO BE SOLVED: To detect a fire for giving an alarm by intensively observing temperatures of predetermined locations with a small, simple, and inexpensive temperature measurement chip and an alarm unit provided separately from the temperature measurement chip and having an alarm part.SOLUTION: Alarm systems A1 to A4 are constituted by arranging a plurality of temperature measurement chips 10-11 to 10-43 allocated for alarm units 100-1 to 100-4 in predetermined locations. For example, when the temperature measurement chips 10-11 to 10-13 allocated for the alarm unit 100-1 of the alarm system A1 detects a fire on the basis of the temperature indicated by temperature measurement results of predetermined locations, such as a stove and a trash can, they transmit a fire detection signal to the alarm unit 100-1 to be made to output a fire alarm. The alarm unit 100-1 is further made to transmit a fire linkage signal to the other alarm units 100-2 to 100-4 of the alarm systems A2 to A4 to be made to output fire alarms. |
