Introduction. The article presents the results of studies on assessing the performance of fire alarm systems in buildings (structures) for various purposes in the period from 2016 to 2020. The analysis of the regulatory framework and the results of previous studies in the field of assessing the effectiveness of fire automatics, including at industrial and residential facilities, is presented. This article explores other types of protected objects.Problem Statement. The objective of the research is to study the efficiency of functioning of fire alarm systems.Theoretical Part. Based on the statistical data for the period from 2016 to 2020 about fires and their consequences, the operability of fire alarms in buildings (structures) for various purposes has been investigated. The social (the number of dead and injured people) and economic (direct material damage) consequences of fires when the fire alarm systems are triggered are analyzed.Conclusion. The results of the study of the operability of the fire alarm in general indicate an increase in the efficiency of its operation compared to the period up to 2016. At the same time, the number of protected objects is characterized by rather low values (less than 50 %) of response efficiency indicators and significant socio-economic consequences of fires.
