EN 54-20:2006 (E) 6 1 Scope This European Standard specifies the requirements, test methods and performance criteria for aspirating smoke detectors for
38、use in fire detection and fire alarm systems installed in buildings. Aspirating smoke detectors developed for the protection of specific risks that incorporate special characteristics (including additional features or enhanced functionality for which this standard does not define a test or assessmen
39、t method) are not covered by this standard. The performance requirements for any special characteristics are beyond the scope of this standard. NOTE Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and they are
40、 not therefore specified in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、ctor smoke detector, in which air and aerosols are drawn through a sampling device and carried to one or more smoke sensing elements by an integral aspirator (e.g. fan or pump) NOTE Each smoke sensing element may contain more than one sensor exposed to the same smoke sample. 3.2 sampling device comp
48、onent or series of components or dedicated device (e.g. a pipe network, dedicated duct, probe or hood) which forms part of the ASD and transfers samples of air to the smoke sensing element(s) NOTE The sampling device may be supplied separately. 3.3 sampling point any point at which an air sample is
49、drawn into the sampling device 3.4 response threshold value (RTV) measure of the aerosol concentration in the proximity of the smoke sensing element at the moment that the specimen generates an alarm signal, when it is tested as described in 6.1.5 3.5 transport time time for aerosols to transfer from a sampling point to the smoke sensing element 3.6 recovery treatment of a specimen, after conditioning, so that the properties of the specimen may be stabilized before measurement of the said property as required by this standard 4 Symbol
