Fire alarm device
专利汇可以提供Fire alarm device专利检索，专利查询，专利分析的服务。并且PURPOSE: To raise a fire alarm in an early stage and surely by using plural smell detectors, and informing a fire in advance by detecting a smell in an initial stage of a fire.
CONSTITUTION: As for a first smell detector 1, a detecting element 11 of an SnO
2 sintering type which scarcely responds to a burning smell generated at the time of fire but responds easily to alcohol, etc., used daily is used, and as for a second smell detector 2, a detecting element 21 of an SnO
2 thin film type which responds easily to a burning small generated at the time of fire but scarcely responds to alcohol, etc., used daily is used. In such a state, when an output of a second smell detector exceeds a prescribed threshold, a fire signal is generated from an alarm circuit in accordance with whether the output of a first smell detector at that time exists in a prescribed range or not. In such a way, a fire can be informed in an earlier stage and more surely than a fire alarm device using a fire sensor of a heat and smoke type.
