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.

Operation
The fusible link assembly is com-
prised of two link halves that are joined
together by a thin layer of solder� When
the rated temperature is reached, the
solder melts and the two link halves
separate, activating the sprinkler and
flowing water�
The Model ESFR-34 Sprinklers are pri-
marily used for ceiling-only sprinkler
protection of (but not limited to) the
following storage applications:
• Most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics
For more specific criteria, refer to Table
B as well as the applicable design
standard�
The Model ESFR-34 can protect a
storage arrangement of 50 ft (15,2 m)
with a ceiling height of 55 ft (16,8 m)
without requiring in-rack sprinklers�
In addition, it can be installed with a
maximum centerline of thermal sensing
element-to-ceiling distance of 17 in�
(432 mm)�
NOTICE
The Model ESFR-34 Sprinklers
described herein must be installed
and maintained in compliance with this
document, as well as with the applica-
ble standards of FM Global, in addi-
tion to the standards of any 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.
In all cases, the appropriate FM instal-
lation standard, or other applicable
standard, must be referenced to ensure
applicability and to obtain complete
installation guidelines. The general
guidelines in this technical data sheet
are not intended to provide complete
installation criteria.

Description
TYCO Model ESFR-34 Pendent Sprin-
klers are Early Suppression, Fast
Response Sprinklers having a nominal
K-factor of 33�6 (See Figure 1)� They are
suppression-mode sprinklers that are
especially advantageous as a means of
eliminating the use of in-rack sprinklers
when protecting high-piled storage�

Installation
TYCO Model ESFR-34 Pendent Sprin-
klers must be installed in accordance
with this section�
General Instructions
Damage to the fusible Link Assem-
bly during installation can be avoided
by handling the sprinkler by the frame
arms only (that is, do not apply pres-
sure to the fusible Link Assembly),
and by using the appropriate sprinkler
wrench� Failure to do so can lead to an
unstable link assembly and premature
activation of the sprinkler� Damaged
sprinklers must be replaced�
A leak-tight 1 1/4 in� NPT sprinkler
joint should be obtained by applying a
minimum-to-maximum torque of 30 to
40 lb-ft (40,7 to 54,2 N∙m)� Higher levels
of torque can distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler�
Note: Install the Model ESFR-34
Pendent Sprinkler in the pendent posi-
tion (See Figure 2).
Step 1. With pipe-thread sealant
applied, hand-tighten the sprinkler into
the sprinkler fitting� Do not apply pres-
sure to the Link Assembly, and handle
the Model ESFR-34 Pendent Sprinkler
only by the Frame arms�
Step 2. Use only the W-Type 26 Sprin-
kler Wrench (See Figure 2) to install
the Model ESFR-34 Pendent Sprinkler�
Fully engage (seat) the wrench recess
on the sprinkler wrench flats (See
Figure 1) and wrench-tighten�
Step 3. After installation, inspect the
Link Assembly of each Model ESFR-34
Pendent Sprinkler for damage� In par-
ticular, verify that the Link Assembly
and Hook are positioned as illustrated
in Figures 1 and 2, and that the Link
Assembly is not bent, creased, or
forced out of normal position in any
way� Replace damaged sprinklers�

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�
