Senju Sprinkler CN-RES Quick Start Manual

Residential Flat Concealed Sprinkler, Pendent,
Model: CN-RES, K-Factor: 4.9, SIN: SS8421

GENERAL DESCRIPTION

The Model CN-RES Residential Flat Concealed Sprinklers are automatic sprinklers of the compressed fusible solder type. These
are decorative and fast response. The frame of the sprinkler hides the deflector, gasket, etc., which is in turn concealed above
the ceiling by the cover plate assembly. The cover plate has a flat profile, and its diameter is extremely small. The
push-on/thread-on, thread-off design of the concealed cover plate assembly allows easy installation of the cover plate. Therefore,
the Model CN-RES should be your first choice when aesthetics is the major consideration for ultimate appeal and unbeatable
performance is desired. The Model CN-RES is designed for the residential occupancies and it is perfect for use in homes, hotels
and other living quarters.
The Model CN-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 CN-RES has a 4.9 (70.6 LPM/bar
pressure, which allows for smaller pipe sizes and water supply requirements.
For extended installation flexibility, the Model CN-RES provides 3/8 inch (9.0mm) 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 CN-RES allows for an increased chance of residents' escape or
evacuation in case of fire. However, residential fire sprinkler systems are not a substitute for fire safety awareness or fire safety
construction required by building codes.
