description: The graduate work is devoted to the development and analysis of the effectiveness of using test fire sources for devices to check the operability of smoke detectors. The object of research is point fire detectors. The subject of research is the development of test smoke sources for testing of point fire detectors. The purpose of the work is to develop a test fire source to assess the performance of point smoke detectors and the effectiveness of its use in testing the functioning of the equipment. To achieve the goal the following tasks were solved: 1.A review of existing methods of testing of point smoke detectors and their shortcomings was carried out. 2.Conducted tests to determine the optical properties of smoke particles for test samples and the behavior of these characteristics throughout the test. 3.Analyzed the smoke particle parameters of the test hearth and justified the choice of the source of test smoke for the test equipment of point smoke detectors. As part of the work on the final qualification work was studied the methodology for assessing the performance of smoke detectors, was tested two test fires that initiated the release of smoke in order to trigger the sensor of point smoke detectors. As part of the experiment, the optical density of the smoke and the variation in particle size were determined at all stages of the tests. To achieve these results, the following databases were used in the work: ConsultantPlus, Tehekspert. The experiments were carried out in the laboratory complex with the participation of the âSmoke channelâ system. The smoke optical density meter functioned on the basis of Arduino software. The methodology of fire detectors testing was carried out according to GOST 34698-2020. Within the framework of the work a comparative analysis of data was carried out and dependences of the optical density of smoke on the time of testing were obtained. The number of test series is regulated by the normative documentation on the test methodology.
