Early Suppression
Fast Response Sprinkler
Product Description
The Reliable Model JL-17 Early Suppression Fast Re-
sponse (ESFR) Sprinkler is intended for use against
severe fire challenges. This sprinkler is designed to re-
spond quickly to growing fires and will deliver a heavy
water discharge to “suppress” rather than “control”
fires.
Note: The Model JL-17 ESFR sprinkler utilizes a le-
vered fusible alloy solder link in either a 165°F (74°C)
or a 212°F (100°C) rating. FM Global considers this
a “Quick Response” storage sprinkler for use in Data
Sheet 8-9.
The sprinkler has a Nominal K Factor of 16.8 (metric
241,9) and will deliver approximately 121 gpm (458 L/
min) of water at 52 psi (3,6 bar).
The smaller deflector and frame provide a broad, very
symmetrical, hemispherical pattern capable of sup-
pressing fires between sprinklers in high storage height
areas and at the same time retaining a high momentum
central core to penetrate and suppress fires occurring
directly beneath the sprinkler in low storage height ar-
eas.
The JL-17 ESFR sprinkler was designed to be short-
er, and more compact than other ESFR sprinklers. The
shorter sprinkler allows piping to be installed further from
the ceiling and obstructions. The JL-17 ESFR sprinkler is
also less susceptible to damage due to smaller deflec-
tor and frame design. The lighter JL-17 ESFR passed
rough use and abuse test in the labs without plastic pro-
tectors.
Application and Installation
The Model JL-17 ESFR sprinkler is intended for instal-
lation in accordance with NFPA 13 and FM Loss Preven-
tion Data Sheets 2-0 and 8-9, as well as the Authority
Having Jurisdiction.
The Model JL-17 ESFR sprinkler is designed for ceil-
ing only sprinkler system with no in-rack sprinklers re-
quired. For encapsulated or non-encapsulated includ-
ing cartoned unexpanded plastics of up to 35 ft (10,7m)
with ceiling heights to 40 ft (12,2m). Model JL-17 ESFR
is also use for cartoned expanded plastics up to 25 ft
(7,6m) with ceilings heights to 30 ft (9,1m) as well as
some storage arrangements of rubber tires, rolled pa-
per, and aerosols.
For storage protection that have up to 40 ft (12,2m)
storage heights with 45 ft (13.7m) ceiling heights, Model
JL-17 ESFR can be used with one level of in-rack sprin-
klers.

Design Criteria
General guidelines:
Sprinkler Position: Pendent, align frame arms with
the pipe. Deflectors should be parallel with the ceil-
ing or roof.

Maximum area of coverage: 100 ft2(9,3m2), greater
coverage area are allowable in some cases.
Minimum area of coverage: 64 ft2(5,8m2)
Maximum slope ceiling: 2/12 pitch (9.5°)
Maximum spacing: 12 ft (3,7m) for building heights
up to 30 ft (9,1m) and 10 feet (3,1m) for building
heights greater than 30 ft (9,1m)
Minimum spacing: 8 feet (2,4m2)
Deflector distance from walls: At least 4 inches
(102mm) from walls, and no more than one-half the
allowable distance permitted between sprinklers.
Deflector to Top of Storage: at least 36in (914mm).
Deflector to ceiling Distance: 6-14 in (152-356mm)
per NFPA 13. 5-14 in (121-35mm) per FM 2-2.
Center Line of Thermal Sensing
Element To Ceiling Distance: 4-13 in (102-330mm)
per FM

Maintenance
The Model JL-17 ESFR Sprinkler should be inspected
quarterly and the sprinkler system maintained in accor-
dance with NFPA 25. Do not clean sprinkler with soap and
water, ammonia or any other cleaning fluid. Remove any
sprinkler that has been painted (other than factory applied)
or damaged in any way. A stock of spare sprinklers should
be maintained to allow quick replacement of damaged or
operated sprinklers. Prior to installation, sprinklers should
be maintained in the original cartons and packaging until
used, to minimize the potential for damage to sprinklers
that would cause improper operation or non-operation.
Once operated, automatic sprinklers cannot be reassem-
bled and reused. New sprinklers of the same size, type
and temperature rating must be installed. A cabinet of re-
placement sprinklers should be provided for this purpose.
Model JL-17 ESFR Sprinkler Specification
Sprinklers shall be Early Suppression Fast Response
(ESFR) pendent suppression mode sprinklers specifically
tested and [UL Listed] [FM Approved] for commodity stor-
age applications. Sprinkler frame and deflector to be of
bronze construction. Fusible link assembly shall utilize the
strut and lever principle of operation with approved fast
response black-painted or white-painted beryllium-nickel
thermal element. Water seal shall consist of a Teflon-coated
Bellville spring washer and brass cap assembly contain-
ing no plastic parts. ESFR sprinklers shall have a nominal
K-factor of 16.8 with ¾” NPT threaded end connections.
Sprinkler temperature rating shall be [Ordinary 165°F
(74°C)] [Intermediate 212°F (100°C)]. ESFR pendent
sprinklers shall be Reliable Model JL-17 (Bulletin 019).
Use only the Model J1
sprinkler wrench for re-
moval and installation. Any
other type of wrench may
damage the sprinkler.
Model J1 Sprinkler Wrench
Note: When handling sprinklers, hold sprinklers only on
frame arms and do not apply any force on the link as-
sembly. Sprinklers should be tightened between 14-20
ft-lbs (19-27,1 Nm) torque.Sprinklers not tightened to
recommended torque may cause leakage or impairment
of the sprinkler. Damage sprinklers must be replaced im-
mediately.
Ordering Information
Specify:
1. Temperature rating
2. Thread type 3/4” NPT or ISO 7-R3/4
Note: Grooved sprinkler boss provided to ensure that the
sprinkler wrench does not slip during installation.
