The broadband infrared sensor is used as a main detector, has a wide response range to infrared light waves, can better identify the infrared light waves, and is used for detecting false alarm energy from a non-fire source and avoiding the occurrence of false alarm.
In the fire alarm device, the mounting plate is provided with mounting holes for fixing with a wall surface, and the mounting holes are uniformly distributed on the edge of the mounting plate.
In the fire alarm device, the protective shell comprises an insulating layer located on the outer side, and a heat insulating layer is arranged in the insulating layer. Thus, the utility model can prevent the fire from high temperature leading to the failure.
In the fire alarm device, the side of the smoke inlet pipe, which is far away from the protective shell, is provided with the flaring section, and the flaring section is provided with the protective net. The flaring section can conveniently suck gas, so that the ion smoke sensor can conveniently detect whether a fire disaster occurs or not, the protective net can prevent insects and the like from entering the smoke inlet pipe, and the smoke particles are small and can smoothly pass through the protective net, so that the identification of the ion smoke sensor is not influenced.
Compared with the prior art, it is with outside air suction ion smoke transducer through axial fan for the collection of smog improves the quantity of the smog granule that detects in the unit interval, to helping discovering the condition of a fire in advance, and whether real conflagration that takes place can further be discerned and judged to infrared photoelectricity fire sensor, in time reports to the police, prevents conflagration development diffusion, and detection mechanism is equipped with alarm mechanism through the conducting ring, and detection mechanism can rotate the detection like this, fixes a position the ignition.
