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
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.

Operation
When exposed to heat from a fire, the
Cover Plate, which is soldered to the
Retainer at three points, falls away
to expose the Sprinkler Assembly.
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, activating the sprinkler and
allowing water to flow.

Installation
The TYCO Model CHEC 8.0 K-factor,
Concealed Horizontal Extended Cov-
erage Quick Response Light Hazard,
Sidewall Sprinklers must be installed in
accordance with this section.
General Instructions
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in.
(1,6 mm).
A 3/4 in. NPT sprinkler joint should be
obtained with a minimum to maximum
torque of 10 to 20 lb-ft (13,4 to
26,8 N·m). Higher levels of torque may
distort the sprinkler inlet with conse-
quent leakage or impairment of the
sprinkler.
Do not attempt to compensate for
insufficient adjustment in the Sprinkler
Assembly by under-or over-tightening
the Sprinkler/Support Cup Assembly.
Readjust the position of the sprinkler
fitting to suit.
To install the Model CHEC Sprinklers,
complete the following steps:
Step 1. The sprinkler must only be
installed with its centerline perpen-
dicular to the back wall and parallel to
the ceiling. Face the word “Top” on the
deflector towards the ceiling.
Step 2. Remove the Protective Cap.
NOTICE
Do not remove the Sprinkler Strap
(Figure 1) until the sprinkler system is
to be placed in service.
Step 3. With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 4. Wrench tighten the sprinkler
using only the W-Type 7 Wrench (Ref.
Figure 3). With reference to Figures 1
and 2, apply the wrench recess of the
W-Type 7 Wrench to the Sprinkler Flats.
Step 5. With reference to Figure 4,
replace the Protective Cap by pushing
it inwards until it bottoms out against
the Support Cup.
Note: The Protective Cap helps prevent
damage to the Sprinkler while the wall
is being plastered, wallpapered, or
painted.

Care and
Maintenance
The TYCO Model CHEC 8.0 K-factor,
Concealed Horizontal Extended Cov-
erage Quick Response Light Hazard,
Sidewall Sprinklers must be maintained
and serviced in accordance with this
section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Asso-
ciation (e.g., NFPA 25), in addition to
the standards of any other authorities
having jurisdiction. Contact the install-
ing contractor or product manufacturer
with any questions.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
When properly installed, there is a
nominal 5/32 in. (4,0 mm) air gap
between the lip of the Cover Plate and
the wall, as shown in Figure 2. This
air gap is necessary for proper oper-
ation of the sprinkler. If the wall is to
be repainted after the installation of
the Sprinkler, care must be exercised
to ensure that the new paint does not
seal off any of the air gap.
