摘要： A separate type photoelectric smoke sensor having a light emitting section for emitting a light beam to a reflecting plate disposed at a certain distance from the light emitting section, a light receiving section for receiving reflected light from the reflecting plate, and a judgement section for outputting a sense signal if a received light output from the light receiving section is smaller than a threshold value previously set. The quantity of reflected light from a shielding object is obtained from the difference between or the ratio of the quantity of received light measured during lighting of the light emitting section in a situation where there is no shielding object and the quantity of received light measured during lighting of the light emitting section in a situation where there is the shielding object, and the difference between these quantities of reflected light and the quantity of received light measured during lighting of the light emitting section is compared with the threshold value to determine whether or not there is a fire. It is thereby possible to correctly discriminate the existence of any shielding object other than smoke in an observed region. Even if there is a shielding object, the influence of the shielding object is cancelled to obtain the true quantity of reflected light from the reflecting plate no matter what the reflectivity thereof, thereby ensuring accurate determination as to whether or not there is a fire.
摘要翻译：一种分离式光电式烟雾传感器，具有发光部分，用于将光束发射到与发光部分一定距离设置的反射板;受光部分，用于接收来自反射板的反射光;以及判断部分，用于输出如果从光接收部分输出的接收光小于预先设定的阈值，则感测信号。来自屏蔽物体的反射光的数量是从不存在屏蔽物体的情况下的发光部照明时测定的接收光量与照明时测定的接收光量之差在存在遮光对象的情况下，将发光部的点亮期间的反射光量与接收光量之间的差与阈值进行比较，判定是否存在遮光对象是火从而可以在观察区域中正确地辨别除烟雾之外的任何屏蔽物体的存在。即使存在屏蔽物体，不管其反射率如何，屏蔽物体的影响被消除以获得来自反射板的真实反射光量，从而确保是否有火灾的准确确定。

摘要： An ionization smoke detector of the present invention comprises an outer electrode having a plurality of smoke inlets formed on a side wall thereof, an outer cover and a partition wall having a plurality of smoke inlets disposed between the outer electrode and the outer cover to form a triple wall structure. The smoke inlets formed on the outer cover, the partition wall and the outer electrode are staggered from each other. Air stream hitting against the detector is attenuated by the triple wall structure and generally half of the air flow is allowed to pass between the outer cover and the outer electrode and between the partition wall and the outer electrode, flowing out of the detector and the remaining half of the air flow is led into the detector through the smoke inlets.

摘要： A light scattering type smoke detector arranged such that even if the range in which light from an LED is emitted has a dispersion, a labyrinth member 90 in the light emitting range has no edge or only a predetermined labyrinth member exist therein. The labyrinth member 90 is preferably formed by a single plate larger than the other labyrinth members 9. The edges of the labyrinth members 9 are preferably formed to a curved surface or chamfered, and the dispersion of the 0 point of a detection output is reduced and the level of the 0 point of the detection signal is lowered to thereby accurately detect light scattered by smoke.
