Substantiation of the Necessity ANR ways to improve European guidelines for fire detection and fire alarm systems.

Abstract

Composition, purpose, and principal functions performed by fire detection and fire alarm systems are described. The incompleteness of the information provided in the European technical specifications for the planning, design, installation, commissioning, use and maintenance of such systems (CEN/TS 54-14:2018) is indicated. A number of other documents establishig requirements on these issues valid in Europe are considered and the need to improve and expand the requirements during the development of future European standards to supersede CEN/TS 54-14:2018 are substantiated. Additions to them are proposed, in particular, an improved block diagram of the sequence of execution of the processes related to fire detection and fire alarm systems as well as an algorithm of actions aimed at reducing the frequency (probability) of false alarms formed by fire detectors. A number of issues related to the protection of premises by installation of point fire detectors under ceilings of various configurations and in certain types of special fire-hazardous premises (facilities) are identified and a solution to their protection is proposed for introducing relevant information to appropriate regulations. The necessity of conducting appropriate desk and experimental studies in order to standardize the procedure for using multi-sensor fire detectors as well as video fire detectors is substantiated. A more detailed description of the procedure for using visual alarm devices to inform people who are in a hazardous area about the occurrence of a fire is offered.
