3 vertical penings, elevatr histways and machine rms, spaces under grund flrs, exterir dcks, and platfrms, exterir rf and canpy, dwelling unit, library stack rm, electrical equipment, ceilings: pen-grid, drp-ut, and stages, Sprinkler is prvided at tp f shaft, refer t exceptins, shafts with cmbustible surfaces require cverage at alternate levels, accessible nncmbustible shaft has sprinkler at bttm, Vertical shaft has sprinklers at tp pening, abve bttm pening and alternate levels when it has cmbustible surfaces, , Sprinklers are prvided beneath cmbustible stairs, Sprinklers are prvided at the tp f the stairway, under the first landing abve the stairway shaft bttm when the shaft and stairs are nncmbustible, Clsely spaced sprinklers with draft stps are prvided arund unenclsed flr penings except large penings like fund in malls r atriums, and penings between flrs f a cmmn dwelling unit, and Elevatr shaft has a sprinkler within 2 ft. f the shaft flr unless the shaft is nncmbustible and there are n cmbustible hydraulic fluids, Ordinary r intermediate temperature sprinklers are in the elevatr machine rm r at the tp f the elevatr shaft, Sprinklers are prvided under cmbustible grund flr, exterir dck, and platfrms, Sprinklers are prvided under rfs and canpies unless cnstructed f nncmbustible r limited cmbustible materials, less than 4 ft. wide, and n strage, refer t exceptins Sprinklers are nt required in nncmbustible dwelling unit bathrms, less than 55 sq. ft. r limited cmbustible with a 15 minute thermal barrier, except in nursing hmes (I-1 and I-2) and in bathrms that have direct access int crridrs and exitways used by the public, Sprinklers are nt required in htel r mtel dwelling unit clthes clset, pantries, r linen clsets less than 24 sq. ft. and the least dimensin is nt greater than 3 ft., Sprinklers are prvided in every aisle and at every tier stack, distance is nt mre than 12 ft. in library stack rms, Page 3 f 5

4 42. Sprinklers are prvided in electrical equipment rms, exceptin: the rm is dedicated use, has dry type equipment, 2 hur equipment enclsures, and n cmbustible strage, Als cnsult the exceptins pertaining t spaces cntaining telecmmunicatin equipment and assciated pwer supplies as specified in CFC sectin Open grid ceilings shall nt be installed under sprinklers, unless the grid pening and sprinkler placement criteria f sectin are met. 44. Drp-ut ceilings are installed under sprinklers in accrdance with their listing, and sprinklers are nt lcated belw the ceilings, Sprinklers fr stages shall be prvided in accrdance with sectin Prscenium penings fr stages shall be prtected in accrdance with sectin HYDRAULIC CALCULATIONS: 47. Indicate the calculatin methd used: density area methd r rm design methd, and Reference pints in the calculatin wrksheet match with pints n the plans, the ccupancy hazard classificatins are crrect fr the ccupancy r use, If design area adjustments are made, the selected shall be indicated, Designs using QR sprinklers shall be in accrdance with sectin Pipe size and length references in the calculatin wrksheet match the plans, (19). 52. Slped ceiling may require a 30 percent increase f design area, Sprinkler data sheet infrmatin matches infrmatin n the plans. 54. Water flw infrmatin is prvided with static PSI, residual PSI, and available GPM at 20 PSI residual with graphed results. 55. Density and design areas infrmatin are prvided and cmply with 12 cnditins listed in sectin , Figure Calculatins are crrect: static PSI, pipe length, GPM, calculated K-factr values fr drps r branch lines, elevatin data, hse allwance, frictin lss, and equivalent pipe and fitting lengths, Fr the rm design methd the design area includes the mst demanding rm and if any, adjacent cnnecting cmpartments, A minimum f tw summary calculatins are prvided fr a grid system, refer t the ne exceptin, Additinal calculatins may be required if the building design and rm uses d nt make the mst demanding area bvius. 60. Legend fr calculatin abbreviatins is prvided. 61. Calculatins are prvided fr extra hazard ccupancies, deluge autmatic sprinkler systems, and expsure prtectin systems. Page 4 f 5

Dry pipe and duble interlck pre-actin design areas are increased 30 percent but the density remains the same ( ), use f high-temp sprinklers in extra hazard ccupancies may reduce design area by 25 percent but nt less than the area specified in REQUIRED INSPECTIONS: 63. Weld and Piping Inspectin Pipe must be n the grund and set fr inspectin (nt bundled): Inspectin f welds and welders stamps that are next t all welds. Ensure all f the cupns are remved frm the hles in the weld--lets 64. Overhead Hydrstatic & Rugh-In Inspectin The system shall be pressurized at 200 psi fr tw hurs with n drp in pressure while piping and bracking is inspected. 65. Fire Sprinkler Final - A main Drain, Inspectr Test and final walk-thrugh f sprinkler cverage shall be perfrmed. The main drain valve shall be pened and remain pen until the pressure stabilizes. Inspectins shall be scheduled a minimum f 48 hurs in advance. Directins fr scheduling are fund at: Page 5 f 5
