ÖNORM EN 54-1

This series of European Standards specifies requirements, test methods and performance criteria against which the effectiveness and reliability of the component parts of fire detection and fire alarm systems can be assessed; requirements and test methods against which the ability of components to be combined into an effective system can be assessed; guidelines for the incorporation and use of fire detection and fire alarm systems into buildings or other construction works. This series of standards applies to fire detection and fire alarm systems for buildings. It may also be used as a basis for the assessment of components of systems for other purposes, e.g. mines, ships; however, additional testing may be required. It does not preclude the manufacture or use of systems having special characteristics suitable for the protection of specified risks. The system is required to function satisfactorily not only under the fire conditions, but also when exposed to conditions likely to be met in practice. The tests specified are intended to assess the performance of the components of the system under such conditions. The performance of components is assessed from the results obtained in the specified tests and from their ability to perform the required functions. This standard is not intended to place restrictions on the design or construction of components other than those necessary for the performance of desired functions. Where appropriate the standards may be applied to the detection part of extinguishing systems (with the exception of sprinkler heads) although the sensitivity requirements may not be applicable to all cases. The compliance of a component with the relevant part of EN 54 does not ensure that this component will necessarily function correctly when connected with another component also complying with the relevant part of EN 54 (e.g. control and indicating equipment with a fire detector), unless both (...abbreviated)
