Sprinkler Location:Locate sprinklers on the underside of the beams(not in the bays or pockets formed by the beams) Refer to Figure 6 The vertical distance from the sprinkler deflector to the bottom of the primary beam must be between 1-1/8 and 1-3/4"(29 to 45 mm; The horizontal distance from the centerline of the sprinkler to the primary beam cannot be more than 2"(51 mm)(Figure 6) NOTE:Consult with a structural engineer before drilling beams to allow the installation of sprinkler drops.Where drilling is not permitted,sprinkler posi- tion requirements allow for the sprinkler drop to be placed adjacent to the primary beam. Beam Position:Directly attached to the underside of a combustible or non-combustible smooth ceiling of any height. Beam Size and Shape(Cross sectionj: • Depth:Maximum 14"(356 mm)for primary beams.Secondary beam depth cannot be greater than the primary beam. • Width:Unlimited. • Beam Shape. Rectangular to circular Beam Types:Combustible or non-combustible,solid surface,solid or hollow core. Beam Spacing: A. For primary beams,the distance from the wall to the center of the nearest primary beam must be at least 3'-4"(1.0 m),and not more than one-half the listed sprinkler spacing.Note:Sprinklers may not be required to be loqted in the first beam nearest the wall.Center-to-center distance between primary beams is to be a maximum of 20 ft(6.1 m).Refer to Figure 7A. B. When beam pockets created by the primary beams exceed 20 ft(6.1 m)in length,secondary beams are required as follows(also refer to Figure 7B): 1 Secondary beam depth must be equal to primary beam depth. 2.Secondary beams must be placed so that the bays formed by the primary beams do not exceed 20 ft(6.1 m)in length. C. 1Nhen primary beam spans do not exceed 20 ft(6.1 m),secondary beams(not requiredj may have any distance from wall to nearest secondary beam and any distance center to center behveen secondary beams.Refer to Figure 7C. Lintels:Must be present over doorways exiting the compartment.Lintel height must be at least 8"(203 mm),or at least thc:depth of the primary beams, whichever is greater Beam and Soffit Arrangements: If a soffit is installed,beams may be arranged within the soffit.The cross section of the soffit may be any size,pro- vided it does not create an obstruction to water distribution per the obstruction rules of NFPA 13 for residential sprinklers.Where there is a so�t,beam spacing from the wall is to be measured from the face of the so�t rather than the wall.Refer to Figure 7D NOTE:The sprinkler area of coverage is to be measured from the wall. Definitions: • Primary beams.The main beams that run primarily in one direction. • Secondary beams:The beams that run perpendicular to the main beams.
