Product Description
Reliable's Model KFR-CCS Combustible Concealed Space
Sprinkler is a quick response, upright, special sprinkler
designed to provide protection of specific light hazard
combustible and noncombustible concealed spaces requiring
sprinkler protection. The KFR-CCS sprinkler is specifically
listed for the protection of shallow combustible concealed
spaces described in NFPA 13.
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 use
in horizontal combustible concealed spaces with a slope
not exceeding 2:12 with combustible wood truss, wood joist
construction, or bar joist construction having a combustible
upper surface and where the depth of the space is less than
36" (914 mm) from deck to deck, from deck to ceiling, or with
double wood joist construction with a maximum of 36" (914
mm) between the top of the bottom joist and the bottom of the
upper joist. NFPA 13 permits the use of the Model KFR-CCS
sprinkler (a) where the space is less than 12" (305 mm) from
deck to deck or deck to ceiling, and/or (b) where a portion of
the protected space exceeds 36" (914 mm).
Installation
Model KFR-CCS Sprinklers are to be installed in the upright
position with their frames arms parallel to the pipe (Refer
to Figs. 4 through 9). 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 immediately void the manufacture's
warranty.
Model KFR-CCS Combustible Concealed
Note: 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). Do not tighten sprinklers over these
recommended limits. Doing so may cause leakage and/or
premature operation.
Maintenance
Model KFR-CCS Sprinklers should be inspected and
maintained in accordance with the applicable version of NFPA
25. Do not clean sprinklers with soap and water, ammonia or
any other cleaning fluids. Remove dust by using compressed
air or by vacuuming, provided equipment does not touch the
sprinkler. Replace any sprinkler which has been painted (other
than factory applied) or damaged in any way. A stock of spare
sprinklers should be maintained to allow quick replacement
of damaged or operated sprinklers. Prior to installation,
sprinklers should be maintained in the original cartons and
packaging to minimize the potential for damage to sprinklers
that would cause improper operation or non-operation.
