  • the detector can communicate with the RFID tag according to any one of the first to fifth aspects, so that the two conditions (i) and (ii) described above are satisfied only when a fire actually occurs. Only when it is satisfied, the disaster prevention equipment ID of the RFID tag can be read, and when the disaster prevention equipment ID is read, the abnormality occurrence is transmitted to an external device together with information capable of specifying the abnormality occurrence location. For this reason, it is possible to reduce false alarms as compared with a configuration in which an abnormality is immediately recognized just because a disaster prevention facility is used.
  • the disaster prevention equipment is a fire extinguisher
  • the operation lever of the fire extinguisher is operated, if there is no fire around and the ambient temperature has not risen, a response The signal is not returned to the detector.
  • the disaster prevention equipment will not be used unless it is a fire, so the response signal is returned to the detector. Not. Therefore, in such cases, it is possible to avoid the inconvenience that the detector erroneously reports the occurrence of abnormality.
  • a fire alarm system (100) according to aspect 7 of the present invention includes the RFID tag according to any one of aspects 1 to 5, and the detector according to aspect 6. As a result, it is possible to realize a fire alarm system capable of avoiding the inconvenience that the detector erroneously reports the occurrence of an abnormality.

Abstract

Le but de la présente invention est de réduire une détection erronée de l'occurrence d'une anomalie. L'invention concerne une étiquette RFID (10) comprenant : une unité de mémorisation (24) qui mémorise des informations concernant un équipement d'atténuation de sinistre (1) ; une unité d'alimentation électrique (21) qui fournit de l'énergie à l'unité de mémorisation afin de permettre la lecture des informations ; une première unité de détection (17) qui détecte de la chaleur dans l'environnement ; une seconde unité de détection (18) qui détecte si l'équipement d'atténuation de sinistre est utilisé ou non ; et des unités de commande de source d'énergie (25, 14, 26, 15) qui, dans une situation où une chaleur supérieure ou égale à une température prescrite a été détectée par la première unité de détection et où la seconde unité de détection a détecté que l'équipement d'atténuation de sinistre est utilisé, active un trajet de courant depuis l'unité d'alimentation électrique vers l'unité de mémorisation.
