Analysis of Reliability Requirements for Fire Alarm Systems Operated in Civil Structures and Critical Infrastructure Facilities

A fire alarm system (FAS) is one of the most important safety facilities used in any building, and include CCTV and intrusion and panic alarms. Pursuant to the Polish Regulation of the Minister of the Interior and Administration of 07/06/2010, FASs are required in specific civil structures. FASs are directly responsible for the protection of the life and health of humans and animals, and indi-rectly for property at the protected sites. In considering the fire hazards and scenarios, a FAS should be characterized with sufficient reliability. Every FAS is subject to specific requirements in terms of reliability and continuity of performance at the stages of monitoring, FAS failure, and fire. This work is an analysis of the reliability requirements for FAS. Keywords: fire alarm system, reliability requirements, structures
