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.
NOTES
Residential Fire Sprinkler Systems should only be designed and installed by individuals who are completely familiar
with automatic sprinkler system design, installation procedures, and techniques.
Several criteria may apply to the installation and usage of each sprinkler. Consequently, it is recommended that the
sprinkler system designer review and develop a working understanding of the complete list of criteria prior to initiating
the design of the sprinkler system.
Questions concerning sprinkler installation and usage criteria, which are not covered by the following instructions,
should be submitted to your contracted company. Include sketches and technical details, as appropriate.
In some instances, the requirements of this document may concern specifications which are more stringent, and which
take precedence over those specified in NFPA 13, 13D, 13R, or by the authority having jurisdiction.
The Model RC-RES must not be used in applications where the air pressure above the ceiling is greater than that below.
Inspect all sprinklers after installation to ensure that both the gap between the cover plate, ceiling and the 6 slots in the
cup are open and free from any air flow impediment.
The spray from the sprinkler is distributed radially outward and downward from the sprinkler deflector. Consequently,
the sprinklers must be located such that there will be no blind spaces shielded from spray by partitions, room dividers,
overhangs or other parts of the dwelling structure.
The number of sprinklers within each compartment (as defined by NFPA 13, 13D, or 13R) must be kept as few as
possible. Do NOT use more sprinklers than necessary to cover a particular space.
Use only the Cover Plate provided for the Model RC-RES. The sprinkler must be secured in place by firmly fastening the
sprinkler system piping to the structure. If the sprinkler is not properly secured in position, reaction forces resulting
from sprinkler operation could alter its orientation and its water distribution pattern.
Obstruction to Water Distribution
Locations of sprinklers must follow the obstruction rules of NFPA 13, 13D and 13R for Residential Sprinklers.
General Service Conditions
The Model RC-RES must only be utilized in WET PIPE sprinkler systems.
Heat Source Criteria
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.

Precautionary Warnings for Corrosive Environments
Model RC-RES sprinklers should not be installed where they may be subjected to a corrosive environment including the
following:
(1) Chlorine ion and Chloride environment.
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.
(2) Sprinkler system piping with Copper.
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)
