EN 54-20:2006 (E) 6 1 Scope This European Standard specifies the requirements, test methods and performance criteria for aspirating smoke det
33、ectors for 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 o
34、r assessment 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 a
35、nd they are not therefore specified in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、 smoke detector 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
43、device component 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
44、 sample is 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 t
45、ransfer 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 Symbols and abbreviations For the purposes of this stan
46、dard, the following abbreviations apply: ASD: Aspirating smoke detector. CIE: Control and indicating equipment. CPC: Condensation particle counter. DUT: Detector under test. EEA: European Economic Area. EMC: Electromagnetic compatibility. EOT: End of test. FPC: Factory production control. EN 54-20:2
47、006 (E) 8 MIC: Measuring ionization chamber. RTV: Response threshold value. 5 Requirements 5.1 Compliance To comply with this standard the detector shall meet the requirements of this clause, which shall be verified by inspection and engineering assessment, and, when tested in accordance with the te
48、sts described in Clause 6, shall meet the requirements of the tests. 5.2 Individual visual alarm indication Each aspirating smoke detector shall be provided with integral red visual indicator(s), visible from outside the aspirating smoke detector, by which the individual smoke sensing element(s) (se
49、e 3.1), which released an alarm, can be identified, until the alarm condition is reset. Where other conditions of the detector may be visually indicated, they shall be clearly distinguishable from the alarm indication. 5.3 Connection of ancillary devices The detector may provide for connections to ancillary devices (e.g. remote indicators, control relays), but open- or short-circuit failures of these connections shall not prevent the correct operation of the detector. 5.4 Manufacturers adjustments It shall not be possible to change the manufacturers
