extended coverage spray sprinklers intended for installation
in accordance with NFPA 13. The sprinklers also have cU-
Lus Listed Specific Application Criteria for installation under
concrete tee construction in accordance with the require-
ments documented in this bulletin. Coverage areas up to
400 ft2 (37 m2) per sprinkler with a maximum spacing of up
to 20 ft by 20 ft (6.1 m by 6.1 m) are permitted for both Light
Hazard and Ordinary Hazard occupancies. Listed flows and
pressures for each hazard classification and sprinkler spac-
ing are provided in this bulletin. Model J112 and JL112 se- Model JL112 Upright Model J112 Upright
ries sprinkler are cULus Listed as quick-response sprinklers
for Light Hazard occupancies. When used in the Ordinary
Hazard occupancies, Model J112 and JL112 series sprin-
klers are cULus Listed as quick-response for spacings up
to 14 ft by 14 ft (4.3 m by 4.3 m) and standard-response for
other listed spacings up to 20 ft by 20 ft (6.1 m by 6.1 m).
Model J112 Pendent and J112 Upright sprinklers use a
glass bulb operating element and are cULus Listed as
Corrosion Resistant Sprinklers when ordered with White
Polyester, Black Polyester, or Electroless Nickel PTFE (ENT)
finish. Model JL112 Pendent and JL112 Upright sprinklers
use a fusible link operating element. Model J112 Pendent Model JL112 Pendent Model J112 Pendent
and Model JL112 Pendent sprinklers are cULus Listed for
use with the Model F2 and Model FP recessed escutch-
eons, which provide up to ½ inch (13 mm) of adjustment. In
addition, for Ordinary Hazard occupancies, the Model J112
Pendent and Model JL112 Pendent sprinklers are cULus
Listed for use with the Model F1 recessed escutcheon that
provides up to ¾ inch (19 mm) of adjustment.

Installation J1 Wrench RJ Wrench
Glass bulb sprinklers have orange bulb protectors to minimize
bulb damage during shipping, handling, and installation. Re-
liable sprinkler installation wrenches are designed to install
sprinklers with bulb protectors in place. Remove the bulb pro-
tector at the time when the sprinkler system is placed in service
for fire protection. Removal of the bulb protector before this time
may leave the bulb vulnerable to damage. Remove bulb protec-
tors by undoing the clasp by hand. Do not use tools to remove
bulb protectors.
Models J112 and JL112 series sprinklers must be installed
with the Reliable sprinkler installation wrench identified in this
bulletin. Any other wrench may damage the sprinkler. Recom-
mended installation torque is 14 to 20 lb.ft (19 to 27 N.m). Do Listings and Approvals
not tighten sprinklers over the maximum recommended installa-
tion torque. Exceeding the maximum recommended installation
Listed by Underwriters Laboratories, Inc. and certified by
torque may cause leakage or impairment of the sprinkler.
