Draft in preparation for 1st enquiry commissioning. Fire detection and fire alarm systems: Page 8 EN Users of British Standards should make sure that they possess the latest amendments or editions. This Directive related to all construction products for installation in any member country of the European Union.
The Regulation provides that where a harmonised technical standard exists for a construction product as defined by the Regulation, that product must be tested and certified to that standard by a notified body in order to qualify for a CE Mark.
Since EN 54 is the harmonised technical standard for fire detection and alarm products, it appears to follow that products in that field which are brought to market in the European Union must be tested against the provisions of EN 54 and certified accordingly. The Construction Products Regulation CPR came into effect from 1 July ; products which are placed on the market in the EU after that date must comply with the provisions of the Regulation, and by extension therefore with EN It is the TC responsible of developing the normative for fire detection system in the EU and responsible for coordination with committees of each member country to update information and making new normative in fire detection system.
For a product to carry a CE Mark , it must fulfill the essential requirements. Fire alarm and Fire detection products, therefore, must follow the requirement laid down in the Construction Products Regulation for testing by a notified body to be carried out against the harmonised technical standard in the field - EN The testing procedure, which is laid down in detail in EN 54, must be carried out by the approved notified body and the official certificatory Declaration Of Performance should be provided by that body.
These reference members are Nationals Organization with authorized certification body by country. National Organization of each country has the same parts numbers. EN 54 standards have been developed by European Committee for Standardization with the approval of their members.
In the United Kingdom it superseded BS Part 1: BS EN From Wikipedia, the free encyclopedia.
