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 automatic
sprinkler systems designed in accor-
dance with standard installation rules
such as NFPA 13 and for light hazard
occupancies. The fast response
thermal sensitivity rating of the sprin-
klers provides for a quick response
extended coverage rating up to a 16 ft
x 16 ft coverage area.
Each unit includes a cover plate assem-
bly that conceals the sprinkler oper-
ating components. The separable
two-piece design of the cover plate and
support cup assemblies allows instal-
lation 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 sprinklers are shipped with a pro-
tective cap. The protective cap is tem-
porarily removed for installation, and it
must be replaced to help protect the
sprinkler while the wall is being plas-
tered, 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.
