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 nomi-
nal K-factor of 16.8. They are suppres-
sion mode sprinklers, and they are es-
pecially advantageous as a means of
eliminating in-rack sprinklers, when
protecting rack storage.
TheModelESFR-17isprimarilyde-
signed for use in ceiling only sprinkler
systems (i.e. no in-rack sprinklers) for
the protection of storage heights of
most encapsulated or non-encapsu-
lated common materials including car-
toned unexpanded plastics of up to 35
ft. (10,7 m) with ceiling heights to 40 ft.
(12,2 m), as well as cartoned ex-
panded plastics up to 25 ft. (7,6 m) with
ceiling heights to 30 ft.(9,1 m). In addi-
tion, the protection of some storage
arrangements of roll paper and rubber
tires can be considered.
In some cases, the Model ESFR-17
can be used to protect storage heights
up to 40 ft. (12,2 m) with ceiling heights
to 45 ft. (13,7 m) in combination with
one level of in-rack sprinklers.
The ESFR-17 provides the system de-
signer with hydraulic options not pres-
ently available to 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 pres-
sures, as compared to ESFR sprin-
klers having a nominal K-Factor of
14.0. This feature offers flexibility when
sizing the system piping, as well as
possibly reducing or eliminating the
need for a system fire pump.
WARNINGS
The Model ESFR-17 Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any other authorities hav-
ing jurisdiction (e.g., FM Global). Fail-
ure to do so may impair the integrity of
these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.

Operation
The fusible link assembly is comprised
of two link halves that are joined to-
gether 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
allowing water to flow.

Design
Criteria
FM APPROVAL 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, ex-
cluding storage of roll tissue, flam-
mable liquids, aerosols, and ex-
posed expanded plastics. Refer to
the appropriate FM Global Data Sheet
and Engineering Bulletin entitled “Tyco
Fire Products Model TY7226, K16.8
Suppression-Model Sprinklers” for de-
tails of appropriate applications and
design specifications.
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 buildings higher
than 30 ft. (9,1 m) 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 minimum
distance of 4 inches (100 mm) below
the ceiling.
D. Hose Stream Demand and Water
Supply Duration:
250 GPM (950 LPM) and 60 minutes
respectively.
F. Other Details: All other details are
the same as for pendent 14.0
K-Factor ESFR sprinklers as recom-
mended in the following FM Global
Data Sheets:
2-2, “Installation Guidelines for Early
Suppression Fast Response Sprin-
klers”
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-storage oc-
cupancies which qualify for use with
quick response sprinklers as indi-
cated in FM Global Data Sheet 3-26,
Table 2, using design guidelines as
described above.
UL AND C-UL
SPECIFIC APPLICATION
LISTING CRITERIA
The Model ESFR-17 Sprinklers (SIN
TY7226) are UL and C-UL Listed as
“Specific Application Early Suppres-
sion Fast Response Sprinklers”. They
are intended for installation and to pro-
tect the same types of storage and
building heights as described in NFPA
13 for UL and C-UL Listed K=14.0
ESFR Sprinklers using the following
K=16.8 ESFR Design Pressures in lieu
of the given K=14.0 ESFR Design
Pressures stated in NFPA 13.

NOTE
Since UL and C-UL currently limit the
listing of K=14.0 ESFR Sprinklers to a
maximum ceiling height of 40 feet
(12,2 m), the specific application of the
Model ESFR-17 is for a maximum ceil-
ing height of 40 feet (12.2 m), even
though NFPA 13 may reference pro-
tection schemes using K=14.0 ESFR
Sprinklers for ceiling heights greater
than 40 feet (12,2 m).

Installation
The Model ESFR-17 Pendent Sprin-
klers are to be installed in accordance
with the following instructions:
NOTE
Damage to the fusible Link Assembly
during installation can be avoided by
handling the sprinkler by the frame
arms only (i.e., do not apply pressure
to the fusible Link Assembly), and by
using the appropriate 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 sprin-
kler 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 pres-
sure 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
on 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 replaced.
Care and
Maintenance
The Model ESFR-17 must be main-
tained and serviced in accordance
with the following instructions:
NOTE
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 authori-
ties 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
shipped or stored where their tempera-
ture 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 sprin-
klers must be replaced.
Care must be exercised to avoid dam-
age - before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage,
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 in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
