SOLUTION: When a first operation unit 6a is operated in any one of fire alarm devices TR, irrespective of whether it is a fire source, fire alarm (alarm sound) which is notified (sounded) from an alarm unit 5 of all fire alarm devices TR is stopped, all at once. When a second operation unit 6b is operated in any one of the fire alarm devices TR, the fire alarm (alarm sound) which is notified (sounded) from the alarm unit 5 of all of the other fire alarm devices TR, except for the fire alarm device TR of the fire source, is stopped all at once. Accordingly, the fire alarm to be notified, in conjunction with all fire alarm devices TR can be alternatively selected, whether it is stopped by all the fire alarm devices TR including the fire source or it is stopped by all of the other fire alarm devices TR, except for the fire source.
