本英国标准是作为一般性指导文件编写的，它极大地帮助解决了与火灾和气体探测安全系统相关的行业中最具挑战性的变量之一。这是第一次，英国标准指导工程师朝着一个坚定的方向前进，从而提高安全系数，因为人们将更好地了解有多少、采用哪种技术以及永久安装的火焰和气体探测器的位置。与BS EN 54和BS 5839不同，BS EN 54和BS 5839分别是建筑火灾探测和报警控制的产品相关和规定性标准，本英国标准是由工业部门对封闭和开放空间危险处理区域的需求驱动的。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This British Standard, which is written as a general guidance document, greatly assists with one of the most challenging variables found in industry pertinent to fire and gas detection safety systems. For the first time, a British Standard guides engineers in a firm direction resulting in greater safety factors as there will be an improved understanding on how many, which technology and where to locate permanently installed flame and gas detectors. Unlike BS EN 54 and BS 5839 which are product related and prescriptive based standards, respectively for fire detection and alarm control in buildings, this British Standard is driven by a demand from the Industrial sector for both enclosed and open space hazardous processing areas.All current amendments available at time of purchase are included with the purchase of this document.
