BS 9251:2005 BSI 31 January 2005 1 Introduction Sprinkler systems have demonstrated their value in protecting life and property in industrial and commercial applications for many years. The advent of sprinklers tha
22、t operate at an earlier stage in the development of a fire, plus the recognition that the largest numbers of deaths from fire occur in the home, have led to the introduction of sprinkler systems specifically designed for residential and domestic occupancies. A correctly designed and installed sprink
23、ler system can detect and control a fire at an early stage of development and activate an alarm. Operation of the system will rapidly reduce the rate of production of heat and smoke, allowing more time for the occupants to escape to safety or be rescued. This British Standard accordingly covers desi
24、gn, installation, components, water supplies, maintenance and testing of residential and domestic sprinkler systems installed for life safety purposes. Residential and domestic fire sprinkler systems are systems in accordance with this standard and consist of a water supply, backflow prevention valv
