Model CHEC — 8.0 K-factor
Concealed Horizontal Extended Coverage
Quick Response Light Hazard, Sidewall Sprinklers
General
Description
The 8.0 K-factor, Model CHEC (Con-
cealed Horizontal Extended Cover-
age), Quick Response Light Hazard,
Sidewall Sprinklers are decorative, 3
mm bulb type sprinklers featuring a
unique cover plate designed to con-
ceal the sprinkler. It is the best choice
for architecturally sensitive areas such
as dormitories, hotel rooms, reception
areas, office buildings, banquet facili-
ties, conference rooms, and hospitals.
The soft contour of the cover plate
optimizes a low profile while blending
in with surrounding surfaces. The
plate, while maintaining a fast re-
sponse sensitivity has been specifi-
cally designed without vent holes to
increase its aesthetic appeal while
helping to avoid objects from being
hung from the sprinkler (i.e., garment
bags, clothes hangers, etc.) that might
otherwise cause an inadvertent opera-
tion.
They are designed for installation
along a wall or the side of a beam and
beneath a smooth and level ceiling.
Horizontal sidewall sprinklers are com-
monly used in lieu of pendent or up-
right sprinklers because of aesthetics
or building construction considera-
tions where piping across the ceiling is
not desirable.
They are intended for use in automatic
sprinkler systems designed in accord-
ance with standard installation rules
(e.g., NFPA 13) for light hazard occu-
pancies. The fast response thermal
sensitivity rating of the Model CHEC
Sprinklers provides for a quick re-
sponse extended coverage rating up to
a 16 ft. x 22 ft. coverage area.
Each unit includes a Cover Plate As-
sembly that conceals the sprinkler op-
erating components. The separable
two-piece design of the Cover Plate
and Support Cup Assemblies allows
installation of the sprinklers and pres-

sure testing of the fire protection sys-
tem prior to the installation of the wall
or application of a finish coating.
Also, the separable "push-on and
thread-off" two-piece design of the the
Sprinkler provides for 1/2 inch (12,7
mm) of horizontal adjustment.
The Model CHEC Sprinklers are
shipped with a Protective Cap. The
Protective Cap is temporarily removed
for installation, and it can be replaced
to help protect the sprinkler while the
wall is being plastered, wallpapered,
or painted. When the wall installation is
complete the Protective Cap is re-
moved and the Cover Plate Assembly
installed.
