systems part one page1 Purpose The Code of Practice for fire detection and alarm systems for buildings (BS 5839- 1) is a detailed and comprehen sive document which requires careful reading to fully understand its’ requi rements and latest approach to ensu ring the safety of buildings and their occupants from the ever present threat of fire. The purpose of this manual is to pro vide a step–by–step approach to the necessary guidelines described in BS 5839-1, so that users can achieve maximum benefit from the recom mendations. This should assist in the task of choosing the best options, help in preparing the specification of the fire protection system and assist architects, designers and electrical engineers in providing the most cost effective system solution that meets the needs of the user.
