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 Series EC-8 Extended Coverage
Pendent Sprinklers are decorative
glass bulb sprinklers designed for use
in light hazard occupancies. They are
intended for use in automatic sprin-
kler systems designed in accordance
with standard installation rules such as
NFPA 13 for a maximum coverage area
of 400 ft2( 37, 2 m 2), as compared to
the maximum coverage area of 225 ft2
(20,6 m2) for standard coverage sprin-
klers used in light hazard occupancies.
The recessed version of the EC-8
sprinkler, intended for use in areas with
a nished ceiling, uses either of the fol-
lowing two-piece escutcheons:
• Style 30 recessed escutcheon
• Style 40 recessed escutcheon
The style 30 recessed escutcheon pro-
vides up to 1/2 in. (12,7 mm) of total
adjustment from the flush pendent
position, whereas, the style 40 provides
3/4 in. (19,1 mm) of vertical adjustment
from the ush pendent position. The
adjustment provided by the recessed
escutcheons reduces the accuracy to
which the xed 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-8 Extended Coverage
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 uid that
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter the
glass bulb, allowing the sprinkler to
activate and ow water.
Design
Criteria
The Series EC-8 Extended Cover-
age Pendent Sprinklers must only
be installed in accordance with the
applicable UL and C-UL Listing or FM
Approval requirements as indicated

installation, as applicable For more
information, see Tables A, B, and C.
UL and C-UL Listing Requirements
1. The Series EC-8 Sprinklers may be
used for the coverage areas shown
in Table D, based on maintaining
the minimum specied ow rate
as a function of coverage area and
hazard group for all of the sprin-
klers in the design area.
2. With respect to heat sensitivity, the
Series EC-8 Sprinklers can be used
with unobstructed construction
consisting of at, smooth ceilings

and permitted by NFPA 13.
3. The minimum allowable spacing
between the Series EC-8 Sprin-
klers, to prevent cold soldering, is

4. The Series EC-8 Sprinklers are
to be installed in accordance with
all other requirements of NFPA 13
for extended coverage pendent
sprinklers.
FM Approval Requirements
The Series EC-8 Extended Cover-
age Sprinklers are to be installed
in accordance with the applicable
Factory Mutual (FM) Loss Prevention
Data Sheet. Information provided in

relate to, but are not limited to, hydrau-
lic design, ceiling slope and obstruc-
tions, minimum and maximum
allowable spacing, and deector-to-

Installation
The Series EC-8 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 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 of an escutch-
eon plate by under-or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler tting to suit.
Step 1. The sprinkler must be installed
with the deector parallel to the mount-
ing surface. Pendent sprinklers must
be installed in the pendent position.
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 tting.
Step 3. Wrench tighten pendent sprin-
klers using only the W-Type 3 (End A)
Sprinkler Wrench. Wrench tighten the
recessed pendent sprinklers using
only the W-Type 23 Sprinkler Wrench.
The wrench recess of the applicable
sprinkler wrench as shown in Figures
4 and 5 is to be applied to the sprinkler
wrench ats as shown in Figure 1.
Care and
Maintenance
The Series EC-8 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 systems must
be obtained from the proper authorities
and all personnel who may be affected
by this action must be notied.
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.
Modied 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. For informa-
tion about replacing a sprinkler, see the
Installation 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. There-
after, annual inspections according
to NFPA 25 should sufce; however,

instead of inspecting from the oor
level, a random sampling of close-up
visual inspections should be made, so
as to better determine the exact sprin-
kler condition and the long term integ-
rity 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 re protection system and devices
in compliance with this document, as
