The utility model ensures that the fire detection in high-cleanliness clean rooms under special conditions such as the air-conditioning maintenance state is more reasonable and effective. That is, a modular installation kit and structure for smoke detectors used in high-cleanliness clean rooms. Background Art

[0002] In recent years, with the commissioning of more and more high-tech and high-cleanliness factories such as semiconductor factories, pharmaceutical factories, and panel factories, the items stored in the factories are of high value, industrial products are complex, and manufacturing equipment is expensive. Therefore, more and more attention has been paid to the fire detection in clean rooms. At the same time, in order to ensure the cleanliness of high-cleanliness clean rooms, the ceiling is usually fully covered with FFUs and clean lamps, and there is no space for installing smoke fire detectors in the ceiling space. Then only air sampling detectors can meet the requirements. However, when the high-cleanliness clean room stops operating or is under maintenance, since air no longer flows from the return air duct for supply and return air, the air sampling detectors arranged in the return air duct and the return air floor cannot normally protect the detection space. If air sampling is arranged again in this detection space for detection, the cost is very high and the sampling pipes are exposed under the ceiling, affecting lighting. Then, if ordinary fire detectors are set in this space, it can not only play a protective role, but also save the use cost and does not affect the normal effect of other systems. Therefore, developing a modular installation kit for smoke detectors used in high-cleanliness clean rooms has become an urgent problem in engineering. Summary of the Utility Model
