17、15423:2008 (E) 4 1 Scope This document gives guidance for system designers, installers, commissioners and maintenance teams on the incorporation of protective measures for air distribution systems including dual purpose systems for smoke and heat exhaust systems within buildings, to prevent the init

18、iation and the spread of fire, smoke and other by-products of combustion. This document intends to only support any national (building) regulations, which are the basis of any design of a building or parts of it. It is up to the designer to enquire about the suitability (in particular in legal terms

19、) of a specific solution given in this document (e.g. although “dual purpose systems” are covered in this document, they may not be permitted in some Member States or only in certain types of buildings). This document applies to all air distribution systems including dual purpose systems (except sys

20、tems only dedicated to smoke exhaust systems, which are dealt in other European standards) including technical rooms or spaces for the installation of devices to assist in ventilation of a building (e.g. distance of storage of combustible materials to devices and not the fire resistance of the build

21、ing structure), penetrations, and following components/products used in the system like: inlet/outlet louvres; fans not exposed / exposed to the smoke; air control dampers; ducts; fire control dampers; air terminal devices; anchors and supports; duct fittings; control panels; cables and connections;

22、 air handling units; air filters; sound attenuators; heat exchangers.

49、used to switch off the motor or to warn of a thermal overload. If necessary fans should be protected, and when they are not connected to a duct they should be protected with metal screens, grids or similar to prevent the entrance of paper, rubbish, and similar foreign material. For fans in air handling units, see also 5.12. 5.3.1.2 Installation Fans shall be located, arranged and installed to afford access for commissioning and maintenance. Fans shall be installed in accordance with the relevant standards and the manufactu
