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

B. System Type: wet-pipe only (no
preaction or dry-pipe).
C. Sprinkler Spacing : The maximum
area of coverage is 100 ft
2
(9,3m
2
) and the minimum area of
coverage is 80 ft
2
(7,4 m
2
).
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-
ply pressure to the fusible Link As-
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.
