GENERAL DESCRIPTION
The Globe Series GL-QR/DC sprinklers are listed Quick
Response domed concealed sprinklers which utilize a 3mm
frangible glass bulb as the thermosensitive operating ele-
ment. They are Listed and Approved as Standard Cover-
age sprinklers and are to be installed in accordance with
the guideline of the appropriate Installation Standard being
mandated by the AHJ (i.e. NFPA 13). While providing addi-
tional aesthetic appeal from that of a semi-recessed sprin-
kler, the GL-QR/DC additionally provides a 1/2” of total ad-
justment. The sprinkler is available in ve temperatures and
the domed cover plate is available in two temperatures. An
optional protective cap (P/N 327119) can be ordered to pre-
vent ceiling installation damage to the sprinkler. The protec-
tive cap is removed and the cover plate is installed when the
system is ready for service. See “Installation” steps within
this document.
OPERATION
The soldered cover plate drops off the retainer assembly
when exposed to heat, as from a re, that has reached
the plate’s Listed temperature rating, exposing the sprin-
kler above. As heat encompasses the glass bulb operating
element of the sprinkler, the uid in the bulb expands, com-
pressing the air bubble within the bulb. When the air bubble
can no longer compress, the uid expansion causes break-
age of the glass bulb, resulting in release of the water seat
assembly and discharge of water from the sprinkler.

INSTALLATION
Step 1. Install pendent sprinklers in the pendent
position, with the centerline of the sprinkler
perpendicular to the mounting surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe-thread sealant applied to the pipe
threads, and using the Concealed Sprinkler
Wrench P/N 325391 or P/N 325401 (FIGURE
2), install and tighten the Sprinkler/Concealed
Cup Assembly into the tting.
Step 4. Replace the Protective Cap by pushing it
upwards until it bottoms out against the Sup-
port Cup. The Protective Cap helps prevent
damage to the Deector and Drop Pins during
ceiling installation and/or during application of
the nish coating of the ceiling.
NOTICE:
The system is considered Out of Service when
the protective caps are in place.
Step 5. After the ceiling has been completed with the
2-1/2” (63.2mm) diameter hole, remove and
discard the Protective Cap and verify that the
Deector has not been damaged. If the sprin-
kler has been damaged , replace the entire
sprinkler assembly. Do not attempt to modify
or repair.
Step 6. Thread on the Cover Plate Assembly until its
ange contacts the ceiling. Never attempt to
screw on the Cover Plate Assembly such that
it lifts a ceiling panel out of its normal posi-
tion. If the Cover Plate Assembly cannot be
engaged with the Mounting Cup or the Cover
Plate Assembly cannot be engaged sufcient-
ly to contact the ceiling, the Sprinkler Fitting
must be repositioned.
NOTICE
Do not install any bulb-type sprinkler if the bulb is cracked or
there is loss of liquid from the bulb. Sprinklers should be tightened
enough to obtain a leak-tight joint when water pressure is applied
and/or hydrostatic test is performed. Sprinklers should not be
overtightened as this can result in distortion and subsequent leak-
age. It is recommended not to exceed 14 ft.-lb. (19.0 Nm) torque
for 1/2 inch NPT sprinkler threads; 20 ft.-lb. (26.8 Nm) to 3/4 inch
NPT threads.

CARE AND MAINTENANCE
Prior to installation, it is important to read and follow the
“Sprinkler Caution” sheet (GFS-840) included within each
box of sprinklers. This sheet is available on Globe’s web
site (www.globesprinkler.com).
Store sprinklers in a cool, dry place. Exposure to extreme
heat will damage the thermal sensing element, possibly re-
sulting in premature activation. Avoid direct sunlight.
Replace any sprinkler that shows any corrosion, damage,
or loss of liquid from the glass bulb.
Do not attempt to paint or alter the sprinkler’s coating or
cover plate in any manner after leaving the manufacturing
plant.
Do not attach wiring, ropes, decorations or xtures to a
sprinkler.
Absence of an escutcheon, used to cover a ceiling hole,
may delay sprinkler operation in a re situation.
It is the owner’s responsibility for inspection, testing and
maintenance of the re sprinkler system with all components
and devices in accordance with the National Fire Protection
Association Pamphlet 25 as well as any other requirements
as set forth by the local Authority Having Jurisdiction (AHJ).
