The outer sheet casing of the circuar curved siencers are buit as a segented bend, BFU. The tear of fibre is prevented since a exposed surfaces are ined. The connections of the circuar types are suppied with a Safe-gasket.

3 indab residentia ventiation Genera The siencers are of the absorption siencer type. The daping abiity of absorption siencers is affected by the geoetric design of the siencer and the type of daping ateria chosen. Siencer coprises a tota of such variants, with different properties. The graph beow suarises the attenuation of soe types of siencer. [db] k k k k More inforation about daping in duct systes, and diensioning and cacuation exapes can be found in the Air Duct syste cataogue. Method of easureent The siencers are tested in accordance with ISO Acoustics - Measureent procedures for ducted siencers - Insertion oss, fow noise and tota pressure oss. Loudspeaker chaber Substitution duct Siencer under test SLCBU 00 BSLCU 0 SLGU 00 0 SLCU 00 0 Fire cass aternatives The Buiding Reguations, BBR, fro the Swedish Nationa Board of Housing, Buiding and Panning contains the foowing paragraph about exchange of fire casses. : Fire cass aternatives Fire cass EI can be exchanged to cass E, if the distance to escape route and to cobustabe ateria is sufficient not to deteriorate the safety of escape nor the risk for fire spread to increase. This eans that e.g. a siencer with E-cass can be used where there is a deand for EI-cass under the presuption that soe specified tie periods and protective distance is achieved. We specify these tie periods and protective distances for our products. Radiation at fire Objects, subjected to radiation, are often divided into three categories. Their axiu aowed radiation intensity eves are: Peope during evacuation Fitting aterias, curtains, drapes etc. Buiding aterias, wood etc. kw/² kw/² 0 kw/² The onger the distance fro a radiation source is the ower the radiation intensity eve. Reverberatio 0 kw/² kw/² kw/² We specify these radiation intensity eves and corresponding protective distances for our products. Type approva The type approved variants are approved on the aspects of fire and tightness according to the certificate nr 00/0. Ceaning of duct systes Siencers with baffes have parts which bock the duct syste to a greater or esser extent, and thus obstruct or prevent ceaning of the duct syste. Pease refer to the Air Duct syste cataogue. Protective distance Protective distance is the shortest distance that is aowed between the siencer and evacuation person or cobustibe aterias.

For bigger sizes, see SLU 0. Noina insuation thickness 0. Attenuation ateria is inera woo. The SLU's are ade of an outer spira seeed tube and an inner tube ade of perforated sheet stee. The space between the is fied with inera woo and a fibre coth is inserted between the perforated sheet eta and the attenuation ateria, to prevent daage to the insuation ateria and fibers fro getting into the duct syste.
