Product Description
The Reliable Model JL-17 Early Suppression Fast
Response (ESFR) Sprinkler with a nominal k-factor of
16.8 (240 metric). This sprinkler is designed to respond
quickly to growing fires and will deliver a heavy water
discharge to “suppress” rather than “control” fires. FM
Global classifies the Model JL-17 as a quick-response
sprinkler, storage and non-storage, when the sprinkler is
used in accordance with FM Global Property Loss Pre-
vention Data Sheets.
The Model JL-17 ESFR sprinkler utilizes a levered fus-
ible alloy solder link in either a 165°F (74°C) or a 212°F
(100°C) rating. Model JL-17 sprinklers are cULus Listed
for compliance with UL/ULC 1767, including the high
clearance test for rack storage.
The Model JL-17 ESFR sprinkler was designed to be
shorter and more compact than other ESFR sprinklers.
The shorter sprinkler allows piping to be installed farther
from the ceiling and obstructions. The JL-17 ESFR sprin-
kler is also less susceptible to damage due to smaller
deflector and frame design. The lighter JL-17 ESFR
passed rough use and abuse listing tests without plastic
protectors.

Application and Installation
The Model JL-17 ESFR sprinkler is intended for instal-
lation in accordance with NFPA 13 and FM Loss Pre-
vention Data Sheets 2-0 and 8-9, as well as the require-
ments of any Authorities Having Jurisdiction. See Table
1 for information on NFPA and FM Global design criteria
for the Model JL-17 sprinkler.
Use only the Model J1 sprinkler wrench for removal
and installation. Any other type of wrench may damage
the sprinkler. A grooved wrench boss is provided on
the sprinkler to limit the potential for the wrench to slip
during installation.

Sprinklers not tightened to recommended torque may
cause leakage or impairment of the sprinkler. Damage
sprinklers must be replaced immediately.
When handling sprin-
klers, hold sprinklers
only on frame arms and
do not apply any force on
the link assembly. Sprin-
klers should be tight-
ened between 14 - 40 ft-
lbs (19 - 54 N-m) torque.
