IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

General
Description
The EC-8C 8.0 K-factor Special Appli-
cation, Quick Response Pendent and
Recessed Pendent Sprinklers are UL
Listed for Light Hazard Occupancies
and were specifically designed for use
in long, narrow spaces such as corri-
dors or hallways with a maximum cov-
erage area of 28 ft by 10 ft (8,5 m x 3,1
m). Fewer sprinklers and lower system
pressure demands are required as
compared to the traditional extended
coverage sprinklers. Series EC-8C
sprinklers are intended for use in auto-
matic sprinkler systems designed in
accordance per NFPA 13.
The recessed version of the Series
EC-8C, Pendent Sprinkler intended
for use in areas with a finished ceiling,
uses either the two-piece Style 30 or
40 Recessed Escutcheon. The Style 30
Recessed Escutcheon provides up
to 1/2 in. (12,7 mm) of total adjust-
ment from the flush pendent posi-
tion, whereas, the Style 40 provides
3/4 in. (19,1 mm) of vertical adjustment
from the flush pendent position. The
adjustment provided by the Recessed
Escutcheons reduces the accuracy to
which the fixed pipe drops to the sprin-
klers must be cut.
Corrosion resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect to the suitabil-
ity of these corrosion resistant coatings
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and gas/
chemical velocity, should be consid-
ered, as a minimum, along with the cor-
rosive nature of the chemical to which
the sprinklers will be exposed.
NOTICE
The Series EC-8C Pendent Sprinklers
described herein must be installed
and maintained in compliance with
this document, as well as with the
applicable standards of the NATIONAL
FIRE PROTECTION ASSOCIATION, in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Operation
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, allowing the sprinkler to
activate and flow water.
Design
Criteria
The EC-8C 8.0 K-factor Special Appli-
cation, Quick Response Pendent and
Recessed Pendent Sprinklers must
only be installed in accordance with
the applicable UL Listing requirements
as indicated below. Only the Style 30 or
40 Recessed Escutcheon is to be used
for recessed installation, as applicable.
UL Listing Requirements
1. The Series EC-8C Pendent Sprin-
klers may be used for the coverage
areas shown in Table A, based on
maintaining the minimum specied
ow rate as a function of coverage
area for all of the sprinklers in the
design area.
2. With respect to heat sensitivity,
the Series EC-8C Pendent Sprin-
klers can be used with unobstruct-
ed construction consisting of at,
smooth ceilings (including bar
joists) with a maximum pitch of one
in six as dened and permitted by
NFPA 13.
3. The minimum allowable spacing
between the Series EC-8C Pendent
Sprinklers, to prevent cold sol-
dering, is 12 ft (3,7 m) in the 28 ft
(8,5 m) long spray direction.
4. The Series EC-8C Pendent Sprin-
klers are not to be installed with the
short spray direction, 8 ft (2,4 m) or
10 ft (3,1 m), oriented towards an-
other Series EC-8C Pendent Sprin-
kler’s short spray direction (See
Figure 6).
5. The Series EC-8C Pendent Sprin-
klers are to be installed in accor-
dance with all other requirements
of NFPA 13 for extended coverage
pendent sprinklers.
Installation
The Series EC-8C 8.0 K-factor Special
Application, Quick Response Pendent
and Recessed Pendent 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 leak tight 3/4 in. NPT sprinkler joint
should be obtained with a torque of
10 to 20 lb-ft (13,6 to 27,1 N·m). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment of an escutch-
eon plate by under-or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Step 1. The sprinkler must be installed
with the deflector parallel to the mount-
ing surface. Pendent sprinklers must be
installed in the pendent position. The
deflector is marked with “<-28 FEET
(8,5 M)->” to indicate the direction of
the 28 ft (8,5 m) coverage length. The
frame arms do not need to be aligned
parallel to the sprinkler pipe.
Step 2. After installing the Style 30 or
40 mounting plate (or other escutch-
eon, as applicable) over the sprinkler
pipe threads, and with pipe thread
sealant applied to the pipe threads,
hand tighten the sprinkler into the
sprinkler fitting.
Step 3. Wrench tighten the deflector so
that the marking “<-28 FEET (8,5 M)->”
on the deflector is in the direction of
the 28 ft (8,5 m) coverage length. The
frame arms do not need to be aligned
parallel to the sprinkler pipe. Use
only the W-Type 6 (End “B”) Sprinkler
Wrench or with a recessed escutcheon
the W-Type 7 Sprinkler Wrench. The
wrench recess of the applicable sprin-
kler wrench (See Figures 4 and 5) is to
be applied to the sprinkler wrench flats
(See Figure 1).

Care and
Maintenance
The EC-8C 8.0 K-factor Special Appli-
cation, Quick Response Pendent and
Recessed Pendent 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 systems must
be obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced. Also, replace any sprin-
kler that has a cracked bulb or that has
lost liquid from its bulb. See Installa-
tion Section.
Frequent visual inspections are rec-
ommended to be initially performed
for corrosion resistant coated sprin-
klers, after the installation has been
completed, to verify the integrity of the
corrosion resistant coating. Thereafter,
annual inspections per NFPA 25 should
suffice; however, instead of inspecting
from the floor level, a random sampling
of close-up visual inspections should
be made, so as to better determine the
exact sprinkler condition and the long
term integrity of the corrosion resistant
coating, as it may be affected by the
corrosive conditions present.
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
ASSOCIATION, such as NFPA 25, in
addition to the standards of any other
authorities having jurisdiction. The
installing contractor or sprinkler man-
ufacturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
