Fire detection and fire alarm systems - Short-circuit isolatorsBS EN 54 17: 2005 specifies requirements, test methods and performance criteria for shortcircuit isolators, for use in fire detection and fire alarm systems for buildings (see EN 54 1). Means of isolation or protection incorporated within control and indicating equipment (item B in Figure 1 of EN 54 1: 1996) are not covered by this European Standard.

that are as basic and generic as possible

The documents detailed in BS EN 10204:2004 are a legal and regulatory requirement that must be provided to those purchasing products as proof of quality and product specification

that specifies the tolerances on dimensions and form for aluminium and aluminium alloy extruded seamless tubes with an outside diameter (OD) from 8 mm to 450 mm or with a cross section contained within a circumscribing circle (CD) from 10 mm to 350 mm (other than round tube) supplied in straight lengths

BS EN 1097-3 provides the requirements for apparatus

BS EN 806 parts 1-5 will eventually fully replace BS 6700:1997
