Model CHEC—8.0 K-factor
Concealed Horizontal Extended Coverage
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, ofce buildings, banquet facili-
ties, conference rooms, and hospitals.
The soft contour of the cover plate opti-
mizes a low prole while blending in
with surrounding surfaces. The plate,
while maintaining a fast response sen-
sitivity has been specically 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 re protection system
prior to the installation of the wall or
application of a nish 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.

Operation
When exposed to heat from a re,
the cover plate, which is soldered to
the retainer at three points, falls away
to expose the sprinkler assembly.
The glass bulb contains a uid that
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter the
glass bulb, activating the sprinkler and
allowing water to ow.

specied in the current NFPA 13 for
extended coverage sidewall sprinklers.
The sprinklers are only listed and
approved with the Model CHEC Cover
Plates having a factory applied nish.
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 ft-lb to 20 ft-lb (13,4 N·m 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
insufcient adjustment in the Sprinkler
Assembly by under-or over-tightening
the sprinkler/support cup assembly.
Readjust the position of the sprinkler
tting to suit.
To install the 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
deector towards the ceiling.
Step 2. Remove the protective cap.
NOTICE
Do not remove the sprinkler strap as
shown in 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
tting.
Step 4. Wrench tighten the sprinkler
using only the W-Type 7 Wrench as
shown in Figure 3. Apply the wrench
recess of the W-Type 7 Wrench to the
sprinkler ats as shown in Figure 1 and
Figure 2.
Step 5. Replace the protective cap by
pushing it inwards until it bottoms out
against the support cup. as shown in
Figure 4.
Note: The protective cap helps prevent
damage to the sprinkler while the wall
is being plastered, wallpapered, or
painted.

Step 7. Push the cover plate/retainer
assembly into the support cup, and as
necessary, make the nal adjustment
of the cover plate with respect to the
wall by turning the cover plate/retainer
assembly clockwise until its ange just
comes in contact with the wall.
If it becomes necessary to remove
the cover plate, it can be removed by
unscrewing in a counter-clockwise
direction.
If the cover plate/retainer assembly
cannot be engaged with the support
cup or the cover plate/retainer assem-
bly cannot be engaged sufciently to
contact the wall, the sprinkler tting
must be repositioned.
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 re protection system
main control valve for maintenance
work on the re protection system that
it controls, permission to shut down the
affected re protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notied.
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Associ-
ation such as 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
qualied 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.
Factory painted cover plates must not
be repainted. They should be replaced,
if necessary, by factory painted
units. Non-factory applied paint may
adversely delay or prevent sprinkler
operation in the event of a re.
