摘要： PROBLEM TO BE SOLVED: To provide a photoelectric smoke sensor having high smoke detection accuracy. SOLUTION: This photoelectric smoke sensor has: a housing 21 having a plurality of wall parts 23 making smoke from the outside flow in the housing 21 and shielding direct light from the outside; a light emission part 25 irradiating light into the housing 21; a light reception part 26 receiving scattered light of the light by the smoke flowing into the housing 21; and a light shielding wall 27 shielding direct light toward the light reception part 26 from the light emission part 25. The light emission part 25 and the light reception part 26 are provided such that respective optical axes of them cross inside the housing 21, and are provided such that the optical axis of the light reception part 26 is directed to an edge part 27a on the optical axis side of the light emission part 25 of the light shielding wall 27.

摘要： PROBLEM TO BE SOLVED: To provide a fire alarm that can prevent a fire alarm from being issued when there is no fire, while issuing the fire alarm immediately in the event of fire. SOLUTION: The fire alarm comprises: a smoke detection unit 3 for detecting smoke; an alarm unit 4 for issuing the fire alarm; and a control unit 2 in which an accumulation time starts to be measured after the time when smoke density based on an output detected by the smoke detection unit 3 reaches a prescribed threshold or larger, and the alarm unit 4 issues the fire alarm when the smoke density continues to be equal to the threshold or larger for a prescribed time. The prescribed time is preliminarily set before the smoke density reaches the threshold or larger. The control unit 2, after the time when at least the smoke density reaches the threshold or larger, discriminates between fire and non-fire on the basis of a frequency spectrum in the amount of change of the smoke density during a prescribed analysis time, before the accumulation time reaches the prescribed time, and performs control either by reducing the prescribed time in the case of fire identification or by prolonging the prescribed time in the case of non-fire identification.

摘要： PROBLEM TO BE SOLVED: To provide a combined type fire alarm for preventing erroneous report, and for announcing fire alarm in an early stage. SOLUTION: This combined type fire alarm is provided with: a smoke detection part for detecting smoke; a CO detection part for detecting CO; and a control part for measuring a storage time T1 when smoke density based on output detected by the smoke detection part turned to an alarm level as the reference of fire alarm or more, and for controlling the fire alarm issue fire alarm after the lapse of the storage time T1 when the smoke density which is the alarm level or more is continuously detected by the smoke detection part during the lapse of the storage time T1. The control part issues fire alarm in the more early stage than the case that the storage time T passes when CO density based on the output detected by the CO detection part reaches the predetermined density or more during the measurement of the storage time T1.
