  • report unit 13 may be a speaker or a buzzer, which may report the occurrence of the abnormality by sound or buzzer sound.
  • report unit 13 may be a light-emitting device, which may report the occurrence of the abnormality by blinking light or the like. For example, the number of times report unit 13 has reported or time at which the reporting has been performed are stored into memory 16.
  • Output unit 14 includes a light source such as, for example, an LED and lights up or blinks. The outer appearance of output unit 14 will be described in FIG. 2 to be described later on. Output unit 14 visually notifies (displays), to the user, the state of abnormality alarm device 10 by the lighting or blinking of the light source. For example, when there is any abnormality in the state of abnormality alarm device 10, output unit 14 notifies, through, for example, blinking, the user that abnormality alarm device 10 is in the aforementioned state.

  • control unit 12 checks the state of abnormality alarm device 10. Note that as one of checks of the state of abnormality alarm device 10, the abnormality check of report unit 13 (speaker) cannot be performed without actually outputting sound from the speaker in many cases. There is a risk that sound is suddenly outputted from the speaker and the user is surprised when the abnormality of the speaker has been checked regardless of user's intent without, for example, the operation performed on operation unit 15.
  • the operation is performed on operation unit 15 (that is, the abnormality of the speaker is checked) depending on user's intent, which therefore makes it possible to suppress the surprise of the user.

Consequently, the user can check the accumulated operation time (for example, years of operation) of abnormality alarm device 10 and judge whether or not it is time to replace abnormality alarm device 10.
  • the information regarding abnormality alarm device 10 may include the accumulated number of times report unit 13 has reported the occurrence of the abnormality. For example, upon every reporting by report unit 13, what has been reported is stored into memory 16, so that the information regarding abnormality alarm device 10 can include the accumulated number of times described above. Consequently, the user can check the accumulated number of times report unit 13 has reported the occurrence of the abnormality.
  • the information regarding abnormality alarm device 10 may include the number of times report unit 13 has reported the occurrence of the abnormality in the predetermined period.
  • the predetermined period is, for example, an immediate one week but is not limited thereto.

For example, upon reporting by report unit 13, the time at which the reporting was performed is stored into memory 16, so that the information regarding abnormality alarm device 10 can include the aforementioned number of times in the predetermined period. Consequently, for example, it is possible for the user to check the number of times the occurrence of the abnormality has been reported in one week (the number of times erroneous report has been done if no abnormality has actually occurred) when the user is away for a long period such as one week.
  • sensor 11 may be a smoke detection sensor of an optical type
  • the information regarding abnormality alarm device 10 may include information indicating the degree of dirtiness of the smoke detection sensor.

  • the chamber rejects external light and can receive smoke and has a black inner wall.
  • the light-receiving element and the light-emitting element are arranged in the chamber so as not to oppose each other.
  • the smoke detection sensor Since the light-receiving element and the light-emitting element do not oppose each other, under the absence of smoke in the chamber, light outputted from the light-emitting element does not hit the light-receiving element and the smoke detection sensor does not detect that the smoke (fire) has been generated.
  • the inner wall of the chamber is dirty with white dust or the like, light outputted from the light-emitting element is reflected by the dust or the like even under the absence of smoke in the chamber, which increases the reception amount of the light-receiving element, leading to a risk of erroneous detection. Therefore, the user can check the degree of dirtiness of the smoke detection sensor and judge whether or not to clean or replace the smoke detection sensor.
