Abstract

The subject of the article is autonomous smoke alarm devices which are point smoke alarm devices. The components necessary for fire detection and technical means for sound and/or voice fire warning are installed in the body of point smoke alarm devices. Autonomous alarm devices are designed for prompt notification of people in premise about the occurrence of smoke generated at the initial stage of fire growth. The scope of application of autonomous alarm devices are residential premises of apartments, hotels, dormitories. Some technical requirements for smoke alarm devices are given in the national standard GOST R 53325-2012 “Fire techniques. Means of fire automatics. General technical requirements and test methods” and the interstate standard GOST 34698-2020 “Fire detectors. General technical requirements. Test methods”. But the nomenclature of these standards is very limited and insufficient to regulate the most significant qualitative and quantitative requirements for autonomous smoke alarm devices. In international practice and in European countries, the requirements for smoke alarm devices are set out in separate standards ISO 12239 «Smoke alarms using scattered light, transmitted light or ionization» and EN 14604 «Smoke alarm devices». The article considers additional requirements, including recommended requirements for smoke alarm devices that are absent in the valid regulatory documents of the Russian Federation.
