PROBLEM TO BE SOLVED: To continuously indicate, for confirmation, the occurrence of abnormality in an automatic test in any manner and prevent replacement of the main body of a fire alarm device from being forgotten even after the stop of an alarm sound notifying the abnormality in the automatic test. SOLUTION: A fire alarm which notifies fire alarm when a fire detection unit detects the fire comprises an abnormality in test detection unit 25 which performs an automatic test for the fire detection unit and outputs test result information; a CPU 24 which controls a fire alarm sound and display light emission on the basis of a test result signal S25 outputtrd from the detection unit 25; and an alarm stop button 19 which is operated so as to make the CPU 24 perform a sound stop input. When detecting the abnormality in the fire detection unit, the CPU 24 starts to control the alarm sound and the display light emission, and when the input is performed from the button 19 after starting the control of the alarm sound and the light emission, the CPU 24 stops to control the alarm sound, and continues to control the light emission.
