7、e NA 031-02-01 AA Brandmelde- und Feueralarmanlagen. This European product standard specifies requirements for multi-sensor fire detectors Point detectors using a combination of smoke, CO and optional heat sensors for use in fire detection and alarm systems permanently installed in buildings (referr
8、ed to in German as “BMS” and “BMA” equipment). The system requirements and technical application rules for fire detection and fire alarm systems complying with this standard are specified in DIN 14675 and DIN VDE 0833-2 (VDE 0833-2). Amendments Compared with DIN EN 54-31:2015-05, the following corre
9、ctions have been made: a) the first element of the English title has been corrected as follows: “Fire detection and fire alarm systems”; b) in Clause 1 “Scope”, the second paragraph has been deleted; c) in 5.3.1, the existing text has been replaced by the following: “A visual inspection of a specime
10、n shall be conducted to verify that the detector meets the requirements for the connection of ancillary devices specified in 4.4.1.”; d) in 5.3.2, the existing text has been replaced by the following: “A visual inspection of a specimen shall be conducted to verify that the detector meets the require
11、ments for the monitoring of detachable detectors specified in 4.4.2.”; e) in 5.3.3, the existing text has been replaced by the following: “A visual inspection of a specimen shall be conducted to verify that the detector meets the requirements for manufacturers adjustments specified in 4.4.3.”; f) in
12、 5.3.4, the existing text has been replaced by the following: “A visual inspection of a specimen shall be conducted to verify that the detector meets the requirements for on-site adjustment of response behaviour specified in 4.4.4.”; g) in 5.3.5, the existing text has been replaced by the following:
13、 “A visual inspection of a specimen shall be conducted to verify that the detector meets the requirements for the protection against the ingress of foreign bodies specified in 4.4.5.”; h) Clause 6 has been deleted; the following clauses have been renumbered appropriately; DIN EN 54-31:2016-12 3 i) i
14、n Annex D, the first sentence of the third paragraph has been replaced with the following: “Means shall be provided for creating an essentially laminar air flow at the required velocities (i.e. (0,2 0,04) m/s or (1,0 0,2) m/s) where the detector to be tested is mounted.”; j) in Annex E, the last sen
15、tence of element b) has been replaced with the following: “The material from which the board is made shall have a thermal conductivity not greater than 0,52 W/(m K).” Element f) has been replaced with the following: “The air-temperature measuring system shall have an overall time constant of not gre
16、ater than 2 s, when measured in air with a mass flow equivalent to (0,8 0,1) m/s at 25 C.”; k) in Annex H, NOTE 1 to Figure H.1 has been deleted; l) in Annex K, the following text has been added to Figure K.1: “Dimensions in cm”; a key has been added to Figure K.4; m) in Annex P, the key to Figure P
