Quick Response Light Hazard, Sidewall Sprinklers
General
Description
The TYCO Model CHEC 8.0 K-factor,
Concealed Horizontal Extended Cov-
erage Quick Response Light Hazard,
Sidewall Sprinklers are decorative,
3 mm bulb type sprinklers featuring a
unique cover plate designed to conceal
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 opti-
mizes a low profile while blending in
with surrounding surfaces. The plate,
while maintaining a fast response sen-
sitivity has been specifically designed
without vent holes to increase its aes-
thetic appeal while helping to avoid
objects from being hung from the sprin-
kler, such as garment bags and clothes
hangers, that might otherwise cause an
inadvertent operation.
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 upright
sprinklers because of aesthetics or
building construction considerations
where piping across the ceiling is not
desirable.
They are intended for use in auto-
matic sprinkler systems designed in
accordance with standard installation
rules, for example NFPA 13, for light
hazard occupancies. The fast response

WARNING" that provides cautions
with respect to handling and instal-

nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

thermal sensitivity rating of the Model
CHEC Sprinklers provides for a quick
response extended coverage rating up
to a 16 ft x 16 ft coverage area.
Each unit includes a Cover Plate
Assembly that conceals the sprinkler
operating components. The sepa-
rable two-piece design of the Cover
Plate and Support Cup Assemblies
allows installation of the sprinklers and
pressure testing of the fire protection
system 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
sprinkler provides for 1/2 in. (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 must 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 must be
removed and the Cover Plate Assembly
installed. The Protective Cap must be
removed to ensure proper performance
of the sprinklers.
