IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage a sprin-
kler system or its components
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 Cover-
age Pendent Sprinklers are decora-
tive glass bulb sprinklers designed
for use in light hazard occupancies.
They are intended for use in automatic
sprinkler systems designed in accor-
dance with standard installation rules
(e.g., NFPA 13) for a maximum cover-
age area of 400 ft2( 37, 2 m 2), as com-
pared to the maximum coverage area
of 225 ft2(20,6 m2) for standard cov-
erage sprinklers used in light hazard
occupancies.
The recessed version of the EC-8, in-
tended 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 inch (12,7 mm) of
total adjustment from the flush pen-
dent position, whereas, the Style 40
provides 3/4 inch (19,1 mm) of verti-
cal adjustment from the flush pendent
position. The adjustment provided by
the Recessed Escutcheons reduces
the accuracy to which the fixed pipe
drops to the sprinklers must be cut.
Corrosion resistant coatings, where
applicable, are utilized to extend the
life of copper alloy sprinklers beyond
that which would otherwise be ob-
tained when exposed to corrosive at-
mospheres. Although corrosion resis-
tant coated sprinklers have passed
the standard corrosion tests of the ap-
plicable approval agencies, the test-
ing is not representative of all possible
corrosive atmospheres. Consequent-
ly, it is recommended that the end
user be consulted with respect to the
suitability of these corrosion resistant
coatings for any given corrosive envi-
ronment. The effects of ambient tem-
perature, concentration of chemicals,
and gas/chemical velocity, should be
considered, as a minimum, along with
the corrosive 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 compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any oth-
er authorities having jurisdiction. Fail-
ure to do so may impair the perfor-
mance 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 ex-
pands 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 Series EC-8 Extended Cover-
age Pendent Sprinklers must only be
installed in accordance with the ap-
plicable UL and C-UL Listing or FM
Approval requirements as indicated
below. Only the Style 30 or 40 Re-
cessed Escutcheon is to be used for
recessed installation, as applicable
(Ref. Table 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
(including bar joists) with a maxi-
mum pitch of one in six as dened
and permitted by NFPA 13.
3. The minimum allowable spacing
between the Series EC-8 Sprin-
klers, to prevent cold soldering, is
8 ft. (2,4 m).
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 Coverage
Sprinklers are to be installed in ac-
cordance with the applicable Factory
Mutual Loss Prevention Data Sheet.
Information provided in the FM Loss
Prevention Data Sheet relate to, but
are not limited to, hydraulic design,
ceiling slope and obstructions, mini-
mum and maximum allowable spac-
ing, and deflector-to-ceiling distance.

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 bub-
ble should be present. The diameter
of the air bubble is approximately 1/16
inch (1,6 mm).
A leak tight 3/4 inch NPT sprinkler
joint should be obtained with a torque
of 10 to 20 ft.-lbs. (13,4 to 26,8 Nm).
Higher levels of torque may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient 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 in-
stalled with the deflector parallel to
the mounting surface. Pendent sprin-
klers 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 fitting.
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 (Ref. Figures 4 and
5) is to be applied to the sprinkler
wrench flats (Ref. Figure 1).

Care and
Maintenance
The Series EC-8 Sprinklers must be
maintained and serviced in accor-
dance 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 au-
thorities 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 dam-
age to the sprinklers before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Ref. 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. Thereaf-
ter, annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive condi-
tions present.
The owner is responsible for the in-
spection, testing, and maintenance
of their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Pro-
tection Association (e.g., NFPA 25), in
addition to the standards of any oth-
er 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, test-
ed, and maintained by a qualified In-
spection Service in accordance with
local requirements and/or national
codes.
