Early Suppression
Fast Response Sprinkler
Product Description
The Reliable Model JL-14 Early Suppression Fast
Response (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-14 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 14.0 (metric
202) and will deliver approximately 100 gpm (378 L/min)
of water at 50 psi (3,5 bar).
The deflector and frame provide a broad, very sym-
metrical, hemispherical pattern capable of suppressing
fires between sprinklers in high storage height areas
and at the same time retaining a high momentum cen-
tral core to penetrate and suppress fires occurring di-
rectly beneath the sprinkler in low storage height areas.
Application and Installation
The Model JL-14 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 Authority
Having Jurisdiction.
This sprinkler is intended for protection of palletized
and solid piled and open frame single row, double row,
multiple row and portable rack storage of most com-
mon materials including unexpanded and cartoned ex-
panded plastics.
The JL-14 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-14 ESFR
sprinkler is also less susceptible to damage due to
smaller deflector and frame design. The lighter JL-14
ESFR passed rough use and abuse test in the labs with-
out plastic protectors.
The Model JL-14 ESFR Sprinkler is FM approved
[165°F (74°C) and 212°F (100°C) temperature ratings
only] when installed in accordance with Factory Mutual
Loss Prevention Data Sheet 8-9 and Data Sheet 2-0 and
other FM Installation Standards.
The Model JL-14 ESFR Sprinkler is UL Listed and Cer-
tified for Canada (all ratings) for installation in accor-
dance with NFPA 13 Standards.
