Предметом статьи является анализ актуализированных требований к проектированию систем пожарной сигнализации, приведенных в своде правил СП 484.1311500.2020 «Системы противопожарной защиты. Системы пожарной сигнализации и автоматизация систем противопожарной защиты. Нормы и правила проектирования». Цель статьи – выявить тенденции, проявившиеся в процессе актуализации требований, проанализировать наиболее существенные изменения требований к проектированию с точки зрения их целесообразности и показать проблемы, возникающие у пользователей свода правил при проектировании систем пожарной сигнализации. Статья предназначена для работников проектных организаций, лиц, ответственных за пожарную безопасность объектов и разработчиков нормативных документов.

The normative document regulating the requirements for the design of fire alarm systems in the Russian Federation is the set of rules SP 484.1311500.2020 “Fire alarm systems and automation of fire protection systems. Designing and regulations rules” (hereinafter referred to as SR 484), which entered into force on March 1, 2021 to replace the set of rules SP 5.13130.2009 “Systems of fire protection. Automatic fire-extinguishing and alarm systems. Designing and regulations rules” (hereinafter referred to as SR 5). The expediency of updating the regulatory framework in the field of rules for the design of fire alarm systems (hereinafter referred to as FAS) is because of the need to update the requirements of SR 5. The SR 484 included requirements for the design of FAS and for fire protection control equipment, such as fire alarm and evacuation control systems in case of fire, smoke ventilation system, automatic fire extinguishing installations, in other words for electronic technical means of the fire automatics system. SR 484 acts in support of the Federal Law No. 123-FZ “Technical Regulations on Fire Safety Requirements”. Compared to the previous requirements, the provisions of SR 484 have strengthened the requirements for automatic monitoring of the integrity of communication lines between the technical means of fire automatics. Requirements have been introduced for permissible consequences in the event of a single failure in communication lines. A restriction has been added on the admissibility of technical means operating as part of the fire automation system to perform functions not related to fire protection of objects. A restriction has been introduced on the number of fire detectors connected to one fire control panel. Recommendations and requirements for dividing an object into fire alarm control zones are given. Three algorithms for generating a fire signal by FAS are formulated. Requirements for the placement of fire detectors are updated. Requirements for equipping objects of protection with addressable and non- addressable FAS are added. As a result of analyzing the experience of SR 484 application it was revealed that some requirements of the document should be changed, supplemented or revised. Currently, such work is already being carried out by the developers of SR 484.
