description: Theme of the final qualification work: âStudy of the influence of dust on the functioning of smoke detectorsâ. The work is devoted to the study of the influence of dust on the operation of smoke detectors of the optoelectronic type. The tasks that were solved during the study: 1. analysis of the current state of the market of fire detectors capable of op-erating under conditions of tough operation. 2. study of the influence of the structure of the body and smoke chamber of the fire detector on the possibility of dust particles settling in it; 3. study of the effect of settled dust on the sensitivity of the fire detector and its false alarms; 4. determination of the most effective design of the smoke detector for in-creased protection against dust and increased sensitivity through the use of forced aspiration and compression of the selected air. The work was carried out on the basis of the laboratory of the Group of Companies Â«GefestÂ», where all experiments were carried out and optical smoke densities were collected at which dusty and non-dusty smoke detectors were triggered. The influence of dust on the correct operation of smoke smoke detectors and the dependence of this influence on the design of the casing and smoke chamber of the detectors were analyzed. A model of a smoke optical-electronic detector with forced aspiration, de-signed to work in conditions of high dustiness, has been developed. The detector design is proposed, which contributes to high protection against dust and, at the same time, high sensitivity.
