GENERAL DESCRIPTION
The Model RC-RES Residential Flat Concealed Sprinklers are automatic sprinklers of the compressed fusible solder type. They
are decorative and fast responding. The Cover Plate Assembly hides the Deflector, Heat Responsive Element etc., which is
concealed above the ceiling. The cover plate has a flat profile, and its diameter is extremely small (2-5/8 inch, 68mm). The
push-on and/or thread-on, thread-off design of the concealed cover plate assembly allows for easy installation of the cover plate.
Therefore, the Model RC-RES should be your first choice when aesthetics is the major consideration for ultimate appeal and
unbeatable performance is desired. The Model RC-RES is designed for residential occupancies and is perfect for use in homes,
hotels and other living quarters.
The Model RC-RES is to be used in wet pipe residential sprinkler systems for One- and Two- Family Dwellings and
Manufactured Homes per NFPA 13D; wet pipe residential sprinkler systems for Residential Occupancies up to and Including
Four Stories in Height per NFPA 13R; or, wet pipe sprinkler systems for the residential portions of any occupancies per NFPA 13.
The Model RC-RES has a 4.9 (70.6 LPM/bar1/2) K-factor that meets the required residential flow rates with minimal residual
pressure, which allows for smaller pipe sizes and water supply requirements.
For extended installation flexibility, the Model RC-RES provides 1/2 inch (12.8mm) vertical adjustment. This adjustment in
installation decreases the need for precise cutting of the pipe that drops to the sprinkler and allows for a perfect fit with a range of
pipe lengths.
The heat sensitivity and water distribution design of Model RC-RES allows for an increased chance of residents to escape or
evacuate in case of a fire. However, residential fire sprinkler systems are not a substitute for fire safety awareness or fire safety
construction required by building codes.
“Lead Free” is defined in the Reduction of Lead in Drinking Water Act (S.3874) endorsed by AWWA’s Water Utility Council, and
California Assembly Bill #1953 as having less than or equal to a weighted average of 0.25% lead in wetted surface of pipes,
plumbing fittings and fixtures.

Physical Characteristics:
In case of fire, the solder component that holds together the Cover Plate and the Retainer melts. Then the Cover Plate is
released at once. As a result, the Deflector drops down to the intended position. Two Heat Collectors are exposed to fire, and
when sufficient heat from the fire is reached, internal components of the sprinkler fall apart. This leads to the water flow to be
distributed on the affected fire area. (Ref. Figure 2)
DESIGN CRITERIA
The herein stated rules for use and installation of Model RC-RES are provided by the manufacturer and must be strictly
implemented for safe and full results.
Locations of sprinklers must follow the obstruction rules of NFPA 13, 13D and 13R for Residential Sprinklers.
The Model RC-RES must only be utilized in WET PIPE sprinkler systems.
Refer to NFPA 13D, 13R or 13 for the requirements relating to the prevention of possible activation of the Heat Responsive
Element of Model RC-RES, due to the exposure of a heat source other than an actual fire.

Model RC-RES sprinklers should not be installed where they may be subjected to a corrosive environment including the
following:
Stress corrosion cracking may be caused by exposure to environments with Chlorine ion and Chloride. Exposure to this
environment may result in sprinklers operating under Non-Fire conditions or Not Operating when exposed to an actual fire.
Sprinkler systems should be constructed in compliance with the applicable standards and the requirements for copper
piping when copper piping is used in the sprinkler system. (Reference standards NFPA 13, ASTM B813, B828, and CDA
(Copper Development Association) – Solder Joint)
All residual flux must be removed from the interior and exterior of the copper piping by thoroughly flushing before
installation of the Sprinkler Heads. Otherwise, residues of flux may cause corrosion and/or leakage in the sprinkler system.
The minimum required sprinkler flow rates for systems designed to NFPA 13D or 13R are given in TABLE A as a function of
temperature rating and the maximum allowable coverage area. The sprinkler flow rate is the minimum required discharge from
the most hydraulically demanding sprinkler from each of the total number of “design sprinklers” as specified in NFPA 13D or
13R.
For systems designed to NFPA 13, the number of designed sprinklers is to be the four most hydraulically demanding sprinklers.
The minimum required discharge from each of the four sprinklers is to be the greater of the following:
The flow rates given in TABLE A for NFPA 13D and 13R as a function of temperature rating and maximum allowable
coverage area.
A minimum discharge of 0.1GPM/sq.ft. [4.07LPM/sq.m] over the “design area” comprised of the four most hydraulically
demanding sprinklers for the actual coverage area being protected by the four sprinklers.
For systems with ceiling types smooth flat horizontal, or beamed, or sloped, in accordance with NFPA 13D, 13R or 13 as
applicable.

(a) For coverage area dimensions less than the above mentioned, it needs to use the minimum required flow for the
Next Higher Coverage Area listed.
(b) Requirement is based on minimum flow in GPM (LPM) from each sprinkler. The associated residual pressures are
calculated using the nominal K-Factor. Refer to Hydraulic Design Criteria Section for details.
The minimum spacing between sprinklers is 8 feet (2.4m). The maximum spacing between sprinklers cannot go beyond the
coverage area calculated by using the specific hydraulic factors. (Ref. TABLE A)
The Model RC-RES must be installed in accordance with the following instructions:
The installation requirements for the sprinkler are as follows: to be installed only in the pendent position with the waterway
perpendicular to the ceiling. Install the sprinkler fitting so that the distance from the face of the fitting to the mounting surface
will be nominally 2 inches (50.8mm) as shown in Figure 3.
With pipe thread sealant applied to the threads, hand tighten the sprinkler into the sprinkler fitting. Then tighten it with the
Socket NR-H or Ratchet (3/8” drive) & Socket NR-H Combination (Ref. Figure 4). The teeth of the Socket must fit perfectly
with the grooves on the Sprinkler for proper installation (Ref. Figure 4).
If desired, the Protective Cap may also be used to locate the center of the clearance hole by gently pushing the ceiling
material against the center point of the Protective Cap. Before the installation of the ceiling, the sprinkler installation can be
started with a 2-3/8 inch (60mm) diameter clearance hole (Ref. Figure 3). Use the “Vertical Adjustment” indicator on the
Protective Cap to check for proper installation height (Ref. Figure 3).
Use the Cap Remover RC to remove the Protective Cap (Ref. Figure 5), and then push or screw a Cover Plate Assembly on
the Cup of the Sprinkler by hand until its flange just has contact with the ceiling (Ref. Figure 6 and Figure 7). Stop tightening
the Cover Plate Assembly once the flange has contact with the ceiling. If the ceiling has been lifted from its normal position in
the process of tightening the Cover Plate Assembly, readjust the cover plate assembly as necessary. If the flange of the Cover
Plate Assembly cannot contact the ceiling sufficiently, readjust the sprinkler fitting as necessary. When properly installed,
there is a nominal 1/16 inch (1.6mm) air gap between the lip of the Cover Plate and the ceiling, as shown in Figure 6.
The following instructions must be implemented for the maintenance and service of the Model RC-RES.
When placing an order, please contact a local distributor with the following information (Model Name, Temperature Rating and
Finish).
