Editing Smoke detector (section)

=== EN54 European standards ===
Fire detection products have the European Standard ''[[EN 54]] Fire Detection and Fire Alarm Systems'' that is a mandatory standard for every product that is going to be delivered and installed in any country in the European Union (EU). ''EN 54 part 7'' is the standard for smoke detectors. European standards are developed to allow free movement of goods in the EU countries. EN 54 is widely recognized around the world. The EN 54 certification of each device must be issued annually.<ref>{{cite web |date=2012-11-11 |title=CEN – Technical Bodies |url=http://www.cen.eu/cen/Sectors/TechnicalCommitteesWorkshops/CENTechnicalCommittees/Pages/Standards.aspx?param=6055&title=Fire%20detection%20and%20fire%20alarm%20systems |archive-url=https://web.archive.org/web/20130520093208/http://www.cen.eu/cen/Sectors/TechnicalCommitteesWorkshops/CENTechnicalCommittees/Pages/Standards.aspx?param=6055&title=Fire%20detection%20and%20fire%20alarm%20systems |archive-date=2013-05-20 |access-date=2014-08-22 |publisher=Cen.eu}}</ref><ref>{{cite web |url=http://shop.bsigroup.com/ProductDetail/?pid=000000000030151892 |title=BS EN 54-11:2001 - Fire detection and fire alarm systems.

* EN54-7: Smoke detector
* EN54-5: Temperature detector
* SA: Surface area
* Smax (square meters): Maximum surface coverage
* Rmax (m): Maximum radio

Information that is in bold is the standard coverage of the detector. Smoke detector coverage is '''60 square meters''' and temperature smoke detector coverage is '''20 square meters'''. The height from the ground is an important issue for correct protection.<ref>{{cite web |url=http://www.aenor.es/DOCUMENTOS/NORMALIZACION/NORMASNACIONALES/EXTRACTOS/(EX)UNE_23007-14=2009.pdf |title=AENOR Noticias |access-date=2013-08-26 |url-status=live |archive-url=https://web.archive.org/web/20131103070833/http://www.aenor.es/DOCUMENTOS/NORMALIZACION/NORMASNACIONALES/EXTRACTOS/(EX)UNE_23007-14=2009.pdf |archive-date=2013-11-03 }}</ref>

An additional (harmonised) EN14604 also exists, which tends to be the standard usually cited at the domestic point of sale. This standard expands on the EN54 recommendations for domestic smoke alarms and specifies requirements, test methods, performance criteria, and manufacturer's instructions. It also includes additional requirements for smoke alarms, which are suitable for use in leisure accommodation vehicles.<ref>{{Cite web |title=CE marking to Smoke Alarm Device–EN 14604_Firefighting Device_Fire test center_FireTC.net |url=http://www.firetc.net/firetesting/show.php?itemid=706 |website=firetc.net}}</ref> However, much of EN14604 is voluntary. A study published in 2014 assessed six areas of compliance and found that 33% of devices claiming to meet this standard did not do so in one or more of the specifics. The study also found 19% of the products to have a problem with actual fire detection.<ref>{{cite web |url=https://cfpa-e.eu/wp-content/uploads/2017/docs/ARTICLE%20final%20aube%202014%20bst.pdf |title=Compliance of Smoke Alarm Devices to EN 14604 - Statistical Analysis of Market Surveillance Results |publisher=ANPI |date=October 2014 |archive-url=https://web.archive.org/web/20181222162026/https://cfpa-e.eu/wp-content/uploads/2017/docs/ARTICLE%20final%20aube%202014%20bst.pdf |archive-date=December 22, 2018 |access-date=October 22, 2022}}</ref>
