Abstract

Smoke detectors as fire detectors present the most frequently used fire detectors from all other detectors. Their great appliance is enabled because smoke presents the consequence of f almost every fire. The realisation of these detectors can be in the form of point smoke detectors, in the form of linear smoke detectors and in the form of special smoke detectors. Generally, there are rules for arrangement of these detectors related to valid standards. Standards in some cases can be similar, but in some cases, there can be some differences between standards. This is specially noted for smoke detectors arrangement in special cases. One of such case is room with girts. Girts can be different located in room and can have functional or aesthetic purpose. This paper was written to present smoke detectors arrangement in room with girts, with different room`s height, related to British standard BS 5839-1 and test all potential cases using FDS simulator.

Summary

INTRODUCTION

Fire detectors present devices with purpose to detect the fire at early stage. Their importance in fire protection is huge, better to write crucial. Fire detectors can be divided differently, mostly related to the fire product (smoke, heat, flame, CO etc.) The most used group of fire detectors present smoke detectors. Their construction was based on two different principles: radioactive principal and optical principal. The arrangement of smoke detectors is strictly defined by rules and standards. There are many similar and many different items in standards related to arrangement of smoke detectors. There are many special cases for fire detectors arrangement where general rules must be modified For those cases, there are similarities and differences between different standards. This paper was written to show the smoke detectors arrangement in case with room with parallel girts related to BS standard (British standard 5839-1) and simulation check of potential cases in FDS software [2]
