Home My WebLink AboutMODEL KFR-CCS SPRINKLERS - 23-00006 - Hibbard Elemenatry - Fire SprinklerFeatures • cULus Listed for areas of coverage up to 256 square feet • Fast response 212°F (100°C) fusible link operating element Product Description The Reliable Model KFR-CCS Combustible Concealed Space Sprinkler is an upright, special sprinkler designed to provide protection of specific light hazard combustible and noncombustible concealed spaces requiring sprinkler protection. The Model KFR-CCS Sprinkler utilizes a fast response solder- link fusible element that has demonstrated response times in laboratory tests which are five to ten times faster than standard response sprinklers. This feature enables the sprinkler to apply water to a fire much faster than standard response sprinklers of the same temperature rating. Application The Model KFR-CCS sprinkler is specifically listed for the protection of horizontal combustible concealed spaces up to 36” deep as described in NFPA 13 and as detailed in this bulletin. In addition, the Model KFR-CCS sprinkler is specifically listed for the protection of horizontal combustible concealed spaces with wood truss and bar joist construction up to and including 60” (900 mm) deep. Installation Model KFR-CCS Sprinklers are to be installed in the upright position with their frames arms parallel to the pipe. When installing the Model KFR-CCS sprinkler use only the Reliable Model W2 installation wrench. Usage of any other type of installation wrench may damage the sprinkler and will void the manufacturer’s warranty. Damaged sprinklers must be immediately replaced. A leak tight ½” NPT (R1/2) sprinkler joint can be obtained with an installation torque of approximately 8 -18 ft-lbs (10.8 – 24.4 N.m) after application of an appropriate thread sealant. Do not tighten sprinklers over these recommended limits. Doing so may cause leakage and/or premature operation. www.reliablesprinkler.com K-factor 5.6 (80); SIN RA4454 cULus Listed Model KFR-CCS Combustible Concealed Space Sprinkler Bulletin 044 December 2022 Maintenance Reliable Model KFR-CCS series sprinklers should be inspected and the sprinkler system maintained in accordance with NFPA 25, as well as the requirements of any Authorities Having Jurisdiction. Prior to installation, sprinklers should remain in the original cartons and packaging until used. This will minimize the potential for damage to sprinklers that could cause improper operation or non-operation. Do not clean sprinklers with soap and water, ammonia liquid or any other cleaning fluids. Remove dust by gentle vacuuming without touching the sprinkler. Replace any sprinkler which has been painted (other than factory applied). A stock of spare sprinklers should be maintained to allow quick replacement of damaged or operated sprinklers. Failure to properly maintain sprinklers may result in inadvertent operation or non-operation during a fire event.

Maximum Distance (Spacing) Between Sprinklers: (Refer to Figures 2 through 7) Maximum Coverage Area Per Sprinkler: (Refer to Figures 2 through 7) Deflector Distance: (Refer to Figures 2 through 7) Minimum Distance Away From Face of Wood Truss or Top Chord of Bar Joist: 4-1/2 in. (114 mm) Obstruction Rules: 1. Sprinklers may not be installed such that the deflector is above the bottom of the top chord of trusses or joists. 2. Gusset plates, truss members, or bar joist members (other than top chords) shall not be considered obstructions provided a min- imum 4-1/2 in. (114 mm) lateral distance from the edge of the member to the centerline of the sprinkler (required by the specific application listing) is maintained. 3. Where the Model KFR-CCS sprinkler is spaced over 225 ft2 (20.9 m2), apply the obstruction rules found in NFPA 13 for extended coverage sprinklers, except as noted in #2 above. 4. Where the Model KFR-CCS sprinkler is spaced 225 ft2 (20.9 m2) or less, apply the obstruction rules found in NFPA 13 for standard spray sprinklers, except as noted in #2 above. Bulletin 044 December 2022 Page 3 of 9 www.reliablesprinkler.com The Model KFR-CCS Sprinkler is specifically listed to provide protection of combustible concealed spaces where (a) the construction method consists of wood trusses or bar joists with top chord depth not exceeding 4 in. (100 mm), (b) the maximum depth of the space is 60 in. (1.5 m) as measured from bottom of deck to top of ceiling, and (c) the slope of the upper deck does not exceed 2 in 12. The Model KFR-CCS Sprinkler is specifically listed to provide protection of combustible concealed spaces where (a) the construction method consists of wood trusses or bar joists with top chord depth exceeding 4 in. (100 mm), (b) the maximum depth of the space is 60 in. (1.5 m) as measured from bottom of deck to top of ceiling, and (c) the slope of the upper deck does not exceed 2 in 12. The Model KFR-CCS Sprinkler is specifically listed to provide protection of combustible concealed spaces where (a) the construction method consists of solid or composite wood joists, (b) the depth of the space does not exceed 36 in. (900 mm) as measured from the bottom of the upper joist to top of the bottom joist (or ceiling if joists are not present), and (c) the slope of the upper deck does not exceed 2 in 12. Unless modified by this technical data sheet, all guidelines provided by the CPVC pipe and fitting manufacturer must be followed. When using CPVC pipe and fittings, horizontal runs of pipe must be a maximum of 6 in. (150 mm) above the ceiling or noncombustible ceiling insulation, or 1/3 the depth of concealed space (as measured from the top surface of the ceiling to the bottom of the deck above), whichever is smaller. Where the members at the bottom of the concealed space are greater than 6 in. (150 mm) tall, installing CPVC piping directly on top of those members shall be permitted. When using 1 in. (DN25) or larger pipe, a hanger must be located at the truss nearest a sprig for purposes of restraint. If using 3/4 in. (DN19) piping, all sprigs over 12 in. (300 mm) must be laterally braced using methods described in the NFPA standards. Where CPVC pipe must be offset up and over an obstruction, the CPVC pipe must be kept within 6 in. of the obstruction and additional Model KFR-CCS Sprinklers are to be installed to protect the CPVC material. A minimum lateral distance of 18 in. (460 mm) must be maintained between the CPVC pipe and heat pumps, fan motors, and heat lamps. CPVC piping can be used to supply the Model KFR-CCS Sprinklers as well as sprinklers installed below the ceiling. Where provided or required, draft curtains shall be at least 1/3 the depth of the concealed space or 8 in. (200 mm), whichever is greater, and shall be constructed using minimum 1/4 in. plywood or other material that will not allow heat to escape through or pass above the draft curtain. Full height walls are acceptable substitutes for draft curtains.
