Resistance of fire detection and alarm systems to environmental factors: foreign and domestic experience of regulation

Introduction. The article presents the results of a study of foreign, national and interstate regulatory documents that regulate the requirements for the stability of technical means of fire automation and automation of fire protection systems to mechanical and climatic influences of the environmental factors. Purpose and objectives. The purpose of the study is a comparative analysis of foreign and domestic experience in the development of regulatory documents for certification testing of technical means of fire automatics, taking into account their possible operation in various conditions and manifestations of the external environment. The objective of the study is to determine the methods for testing the performance of technical means of fire automatics under various external influences as part of the creation of a test base for reference laboratories provided for by the federal project "Systemic measures for the development of international cooperation and exports". Methods. The study applied the methods of apperception, axiomatic and descriptive analysis of literary sources (standards) in the field of testing fire detection and alarm systems. Research results. On the basis of a comparative analysis of foreign, national and interstate standards, the experience of developing test methods for fire detection and alarm systems for various types of environmental factors. Conclusions. In a comparative comparison, the test methods used in foreign and domestic practice for fire detection and alarm systems differ from each other both in the intensity of the tests themselves and in the types of simulating external influences, including exposure time, which is longer in foreign methods than in national and interstate ones. So, during certification foreign tests, the product is subjected to the full scope of tests once after the product is put into mass production and appears on the market. In Russian practice, the product is tested once every five years in full. Keywords: fire automatics; certification tests; external impact; mechanical and climatic factors; reference laboratory.
