   <abstract xml:lang="ru">
    <p>Для обеспечения безопасности граждан и объектов защиты в высотных зданиях проектируются и устанавливаются системы пожарной сигнализации. Одним из ключевых факторов при ее проектировании является характер распространения дыма&#13;
при пожаре, который, в свою очередь, сильно зависит от высоты потолков.&#13;
Предметом исследования выступает процесс распространения дыма при пожаре в помещениях различной высоты.&#13;
Методологическая база исследования включает численное моделирование данного процесса, которое было осуществлено в программном продукте Fire Dynamic Simulation с дальнейшей визуализацией данных в Smokeview.&#13;
Полученные данные свидетельствуют о том, что при высоте потолков 4 и 8 м вертикальный уровень задымления происходит быстрее горизонтального, в связи с чем на этих высотах предпочтительнее установка дымовых линейных извещателей традиционным способом (горизонтально). Начиная с высоты потолков в 12 м более выгодным является расположение дымовых линейных извещателей вертикально. Выявленные особенности могут быть полезны как на этапах проектирования, так и монтажа систем пожарной сигнализации. В рамках направлений дальнейших исследований целесообразно исследовать процесс распространения дыма в помещениях различной высоты и геометрии более детально и на основе полученных данных осуществить изменение действующих нормативно-правовых документов, регламентирующих проектирование систем пожарной сигнализации.</p>

    <p>To ensure the safety of citizens and protected facilities, fire alarm systems are designed and installed in high-rise buildings. One of the key design factors is the nature of smoke propagation during a fire, which in turn is highly dependent on ceiling height.&#13;
This study examines smoke propagation during a fire in high-rise buildings.&#13;
The study's methodology includes numerical modeling of this process, which was performed using Fire Dynamic Simulation software, followed by data visualization in Smokeview.&#13;
The data obtained indicate that at ceiling heights of 4 and 8 meters, vertical smoke accumulation occurs faster than horizontal smoke accumulation. Therefore, at these heights, traditional horizontal installation of linear smoke detectors is preferable. Above ceiling heights of 12 meters, vertical placement of linear smoke detectors is more advantageous. The identified characteristics can be useful both during the design and installation stages of fire alarm systems. As part of further research directions, it is advisable to study the process of smoke propagation with a smaller step in ceiling height and, based on the data obtained, make changes to the current regulatory documents governing the design of fire alarm systems.</p>
