General independent smoke detector series three: how to choose independent smoke

In front of the articles to explain what is independent of smoke detectors and independent type smoke detector common, you read, will initiation of such a question: independent smoke these species, that my house is the installation of what types of products? The following for you to popularize the knowledge.

We know that the object in the combustion will produce smoke, some objects when burning smoke, some objects when burning smoke is very small. This is mainly with the material structure of the object, is also related to the severe degree of combustion. For example, our common clothes on fire, will produce huge amounts of black smoke, smoke particles is relatively large. Books and newspapers on fire, the smoke concentration is relatively small, the smoke particles are also relatively small. Photoelectric type independent smoke detector is sensitive to the smoke particles larger, ion type independent smoke smoke detector is sensitive to small granules.

So we consider in the purchase of independent smoke detectors installed under the environment of it, if you want to put in the bedroom, can buy a photoelectric type, if want to install in the study, is to buy a ion type. Of course, if economic conditions permit, the best is the two detectors are mounted on the.
