Estimation of the performance of the fire alarm systems at the residential facilities for the period from 2016 to 2020

Introduction. The issues of the operability of fire alarm systems at housing facilities are considered. Regulatory requirements and the results of scientific research on the functioning of these systems are analyzed. The results of assessments of the effectiveness of fire alarm systems actuation at housing facilities are presented, taking into account their characteristics for the period from 2016 to 2020. Goal and objectives. The purpose of the study is to investigate the effectiveness of fire alarm systems in houses and apartment buildings. The objective of the study is to identify the features of the functioning of fire alarm systems at housing facilities, taking into account their characteristics. Methods. Two options for assessing the effectiveness of fire alarm systems are considered. The first one is based on identification of the number of cases of implementation of various modes of functioning of fire alarm systems. The second one is based on taking into account the social consequences of fires. Results and discussion. Evaluation of the operability of fire alarm systems showed that the efficiency of fire alarm systems for houses is 83,1 %, for apartment buildings - 75,7 % on average, for the period from 2016 to 2020. At the same time, the highest value of the response efficiency (86,4 %) is observed for apartment buildings with more than 25 floors and for houses of I degree of fire resistance (82,4 %). The number of people injured in fires per one fire for houses is much less in conditions when the fire alarm systems operated signaled (0,4 people per fire) compared to conditions when these systems did not fulfill their task (0,75 people per fire). Conclusion. Compared to the period 2005-2012, the effectiveness of fire alarm systems in the residential sector has increased significantly. On average, the level of performance by fire alarm systems was 83,1 % for houses and for apartment buildings - 75,7 % for the period from 2016 to 2020.
