Abstract
PURPOSE:To quickly and surely inform a fire in spite of the density variation of smoke accompanied with the operation state of an air-conditioning equipment by switching a fire discrimination reference of a fire discrimination means based on the operation information of the air-conditioning equipment. CONSTITUTION:In case a fire detection means SE is provided in a room, for example, the smoke caused by the fire is diffused and diluted and the smoke density near the provided position of the fire detection means SE when a ventilation frequency by the air-conditioning equipment AC is increased. Then the ventilation frequency is inputted as the operation information to a switching means 25 from the air-conditioning equipment AC through a receiving means 35 and the fire discrimination reference of the fire discrimination means 36 is switched to a high sensitivity side by the switching means 25 and the fire is informed. Thus since the fire discrimination reference can be properly switched in conformity with the degree of the diffusion and the dilution of the smoke of the fire according to the operation state of the air-conditioning equipment AC, mistaken information, no information or delay information can be prevented and the fire can be quickly and surely informed.
