Particle Detectors: (4.26) Smoke Detector: (5) European Smoke Alarm Standard: 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 standard are developed to allow free movement of goods in the European Union countries. EN 54 is widely recognized around the world. The EN 54 certification of each device must be issued annually. The following table shows the Coverage of Smoke Detector and Temperature detector with Euroean Standard EN54 (sqm): Superfice area (sqm): SA ≤80, Type of Detector: EN54-7, Heigh (m): ≤12, Smax(sqm) with Roof Slope ≤20º: 80, Rmax (m) with Roof Slope ≤20º: 6,6, Smax (sqm) with Roof Slope >20º: 80, Rmax(m) with Roof Slope >20º: 8,2; Superfice area (sqm): SA >80, Type of Detector: EN54-7, Heigh (m): ≤6, Smax(sqm) with Roof Slope ≤20º: 60, Rmax (m) with Roof Slope ≤20º: 5,7, Smax (sqm) with Roof Slope >20º: 90, Rmax(m) with Roof Slope >20º: 8,7; Superfice area (sqm): No Report, Type of Detector: No Report, Heigh (m): 6< h ≤ 12, Smax(sqm) with Roof Slope ≤20º: 80, Rmax (m) with Roof Slope ≤20º: 6,6, Smax (sqm) with Roof Slope >20º: 110, Rmax(m) with Roof Slope >20º: 9,6; Superfice area (sqm): SA ≤30, Type of Detector: EN54-5 Clase A1, Heigh (m): ≤7,5, Smax(sqm) with Roof Slope ≤20º: 30, Rmax (m) with Roof Slope ≤20º: 4,4, Smax (sqm) with Roof Slope >20º: 30, Rmax(m) with Roof Slope >20º: 5,7; Superfice area (sqm): SA ≤30, Type of Detector: EN54-5, Clase A2,B,C,D,F,G, Heigh (m): ≤ 6, Smax(sqm) with Roof Slope ≤20º: 30, Rmax (m) with Roof Slope ≤20º: 4,4, Smax (sqm) with Roof Slope >20º: 30, Rmax(m) with Roof Slope >20º: 5,7. (Note: EN54-7, Smoke detector; EN54-5, Temperature detector; SA = Superfice Area; Smax(sqm) = Maximun Superfice coverage; Rmax (m) = Maximun Radio). information in "bold" is the standard coverage of the detector. Smoke detector coverage is 60sqm and tempetature smoke detector is 20sqm. Heigh from ground is an important issue for a correct protection. You can see "High" in the table for this information
