Tyco Fire Product CENTRAL ESFR-17 User manual

General
Description
The Model ESFR-17 Sprinklers (Ref.
Figure 1) are “Early Suppression
Fast Response Sprinklers” having a
nominal K-factor of 16.8. They are
suppression mode sprinklers, and
their use is especially advantageous
as a means of eliminating the use of
in-rack sprinklers, when protecting
high-piled storage.
The Model ESFR-17 is primarily de-
signed for use in ceiling only sprin-
kler systems (i.e. no in-rack sprin-
klers) for the protection of storage
heights of most encapsulated or non-
encapsulated common materials in-
cluding cartoned unexpanded plas-
tics of up to 35 ft. (10,7 m) and with
ceiling heights of up to 40 ft. (12,2
m), as well as cartoned expanded
plastics of up to 25 ft. (7,6 m) with
ceiling heights of up to 30 ft.(9,1 m).
In addition, the protection of some
storage arrangements of roll paper
and rubber tires can be considered
as well.
Also, in some cases, the Model
ESFR-17 can be used to protect stor-
age heights up to 40 ft. (12,2 m) with
ceiling heights up to 45 ft. (13,7 m)
in combination with one level of in-
rack sprinklers.
The ESFR-17 provides the system
designer with hydraulic options not
presently available to the traditional
ESFR sprinklers having a nominal
K-Factor of 14.0. In particular, the
Model ESFR-17 has been designed
to operate at substantially lower end
head pressures, as compared to
ESFR sprinklers having a nominal
K-Factor of 14.0. This feature offers
flexibility when sizing the system pip-
ing, as well as possibly reducing or
eliminating the need for a system fire
pump.
Operation. The fusible link assembly
is comprised of two link halves which
are joined together by a thin layer of
solder. When the rated temperature
is reached, the solder melts and the
two link halves separate, which then
allows the sprinkler to activate and
flow water.
WARNINGS
The Model ESFR-17 Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the appli-
cable standards of the National Fire
Protection Association, in addition to
the standards of any other authori-
ties having jurisdiction (e.g., FM
Global). Failure to do so may impair
the integrity of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
sprinkler manufacturer should be
contacted relative to any questions.

Physical Characteristics
The Model ESFR-17 utilizes a dezin-
cification resistant bronze alloy
frame. The strut and hook are monel;
and, the button, deflector, and com-
pression screw are bronze. The
frame orifice is sealed with a gas-
keted spring plate (Belleville Seal)
consisting of a beryllium nickel disc
spring that is sealed on both its in-
side and outside edges with a Tef-
lon  gasket, and the two halves of
the fusible link assembly are nickel.

Design
Criteria
The Model ESFR-17 Sprinklers (SIN
TY7226) may be used to protect the
same types of storage and building
heights (up to 40 ft. (12,2 m) without
in-rack sprinklers, or 45 ft. (13,7 m)
with one level of in-rack sprinklers)
as 14.0 K-Factor ESFR sprinklers,
excluding storage of roll tissue,
flammable liquids, aerosols, and
exposed expanded plastics. Refer
to the appropriate FM Global Data
Sheet and Engineering Bulletin enti-
tled “Tyco Fire Products Model
TY7226, K16.8 Suppression-Model
Sprinklers” for details of appropriate
applications and design specifica-
tions.
A. Hydraulic Design: Design should
be 12 sprinklers, supplying four
sprinklers on three branch lines, at
the following pressures based on
equivalence to 14.0 K-Factor
ESFR sprinkler flows:
K=14.0 K=16.8

75 (5,2) 52 (3,6)
90 (6,2) 63 (4,3)
B. System Type: wet-pipe only (no
preaction or dry-pipe).
C. Sprinkler Spacing: The maximum
area of coverage is 100 ft2
(9,3m2) and the minimum area of
coverage is 80 ft2(7,4 m2).
The maximum distance between
sprinklers on branch lines or be-
tween branch lines is 12 ft. (3,7 m)
for buildings up to 30 ft. (9,1 m)
high, and 10 ft. (3,1 m) for build-
ings higher than 30 ft. (9,1 m) and
up to 45 ft. (13,7 m).
The minimum distance between
sprinklers on branch lines or be-
tween branch lines is 8 ft. (2,4 m).
C. Sprinkler Position: Position sprin-
klers so that the deflectors are lo-
cated at a maximum distance of
14 inches (360 mm) and a mini-
mum distance of 4 inches (100
mm) below the ceiling.
D. Hose Stream Demand and
Water Supply Duration:
250 GPM (950 LPM) and 60 min-
utes respectively.
F. Other Details: All other details are
the same as for pendent 14.0
K-Factor ESFR sprinklers as rec-
ommended in the following FM
Global Data Sheets:
2-2, “Installation Guidelines for
Early Suppression Fast Response
Sprinklers”
8-3, “Rubber Tire Storage”
8-9, “Storage of Commodities”
8-21, “Roll Paper Storage”
8-24, “Idle Pallet Storage”
G. Mixed Occupancies:
16.8 K-Factor ESFR sprinklers
may be used in adjacent non-stor-
age occupancies which qualify for
use with quick response sprinklers
as indicated in FM Global Data
Sheet 3-26, Table 2, using design
guidelines as described above.
Installation
The Model ESFR-17 Pendent Sprin-
klers are to be installed in accord-
ance with the following instructions:
NOTE
Damage to the fusible Link Assem-
bly during installation can be
avoided by handling the sprinkler by
the frame arms only (i.e., do not ap-
plypressuretothefusibleLinkAs-
sembly), and by using the appropri-
ate sprinkler wrench. Damaged
sprinklers must be replaced.
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 leakage or impairment
of the sprinkler.
Step 1. The ESFR-17 Sprinkler must
be installed in the pendent position.
Step 2. With pipe thread sealant ap-
plied, hand tighten the sprinkler into
the sprinkler fitting. Do not apply
pressure to the Link Assembly, and
handle the ESFR-17 Sprinkler only
by the Frame arms.
Step 3. Wrench tighten the ESFR-17
Sprinkler using only the W-Type 21
Sprinkler Wrench (Ref. Figure 2) and
by fully engaging (seating) the
wrench with the sprinkler wrench
flats.
Step 4. After installation, inspect the
Link Assembly of each ESFR-17
Sprinkler for damage. In particular,
verify that the Link Assembly and
Hook are positioned as illustrated in
Figure 1, and that the Link Assembly
has not been bent, creased, or
forced out of its normal position in
any way.
Damaged sprinklers must be re-
placed.

Care &
Maintenance
The Model ESFR-17 must be main-
tained and serviced in accordance
with the following instructions:
NOTE
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem which it controls, permission to
shut down the affected fire protec-
tion systems must be obtained from
the proper authorities and all person-
nel who may be affected by this ac-
tion must be notified.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
shipped or stored where their tem-
perature will exceed 100°F/38°C and
they must never be painted, plated,
coated, or otherwise altered after
leaving the factory. Modified or over-
heated sprinklers must be replaced.
Care must be exercised to avoid
damage - before, during, and after
installation. Sprinklers damaged by
dropping, striking, wrench twist/slip-
page, or the like, must be replaced.
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 Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any
other authorities having jurisdiction.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
