45、 following apply. 3.1 aspirating 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
46、same smoke sample. 3.2 sampling 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
47、 point any point at which an air 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 trans
48、port 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 Symbols and abbreviatio
