GENERAL DESCRIPTION
The GL-RES/DC Domed Concealed pendent sprinkler is
a decorative fast response glass bulb sprinkler specically
tested and Listed for use in residential applications such
as homes, apartments, hotels, and dormitories to provide
control of these residential type res and to improve the
chance for occupants to escape. These sprinklers utilize
a 3mm frangible glass bulb as its heat sensing operating
element. The GL-RES/DC is available with a K-Factor of 4.1
(GL4147) and a K-Factor of 4.9 (GL4947) and offer a further
level of aesthetic appeal compared to semi-recessed type
sprinklers.
These sprinklers provide a total vertical adjustment of a
nominal 1/2”. This sprinkler may be installed within dwelling
occupancies as allowed by NFPA 13, 13D, 13R and any
other related documents as appropriate.
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.

DESIGN CRITERIA
The Globe Series GL-RES/DC Sprinkler is cULus Listed for
installation in accordance with this data sheet as well as the
applicable installation Standard being utilized.
Globe Residential Sprinkler Installation Guide
When conditions exist that are outside the scope of the pro-
vided criteria, refer to the Globe Residential Sprinkler Instal-
lation Guide (Document GFS-380) for recommendations
that may be acceptable to the authority having jurisdiction.
Hydraulic Design (NFPA 13D and 13R)
For systems designed to NFPA 13D or NFPA 13R, the min-
imum required sprinkler ow rate is given in Table A for the
coverage areas shown. The sprinkler ow rate is the min-
imum required discharge from each of the total number of
“design sprinklers” as specied in NFPA 13D or NFPA 13R.
Hydraulic Design (NFPA 13)
The minimum required discharge from each design area
sprinkler shall be the greater of the following:
(1) In accordance with minimum ow rates indicated in
TABLE A.
(2) In rooms or compartments greater than 800 ft2
(74.3 m2), calculated based on delivering a minimum
of 0.1 gpm/ft2(4.1 mm/min) over the coverage area of
each sprinkler, calculated in accordance with the
S x L Rules for density area sprinklers.
(3) In rooms or compartments 800 ft2(74.3 m2) or less
(Dened as “Small Rooms”) calculated based on de-
livering a minimum of 0.1 gpm/ft2(4.1 mm/min) over
the room or compartment using the area of the room
divided by the number of sprinklers in the room. (7 psi

CARE AND MAINTENANCEINSTALLATION
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 (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 moves up and down freely. If the
sprinkler has been damaged or the deector
does not move up and down freely, replace
the entire sprinkler assembly. Do not attempt
to modify or repair.
Step 6. Push 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.
Always obtain permission from the proper authorities to
shut down the affected re protection system and notify all
personnel who may be affected by this action before closing
a re protection system main control valve for maintenance
work on the system that it controls. Sprinklers should only
be cleaned by means of gently dusting with a feather dust-
er; otherwise, non-operation in the event of a re or inadver-
tent operation may result.
When properly installed, there is a nominal 1/8” (3mm) air
gap between the Cover Plate and the ceiling (Figure 1). This
air gap is necessary for proper operation of the sprinkler by
allowing heat ow from a re to pass below and above the
Cover Plate to help assure appropriate release of the Cover
Plate in a re situation. This annular “gap” must be main-
tained and should never be sealed or caulked.
Factory painted Cover Plates must not be repainted.
In accordance with NFPA 25, Sprinklers which are found to
be leaking or exhibiting visible signs of corrosion must be
replaced.
Automatic sprinklers must never be painted, plated, coated,
or otherwise altered after leaving the factory.
Care must be exercised to avoid damage to the sprinklers–
before, during, and after installation. Sprinklers damaged
by dropping, striking, wrench slippage, or similar incidents,
must be replaced.
The owner is responsible for the inspection, testing, and
maintenance of their re protection system and devices in
compliance with this document, as well as with the appli-
cable standards of the National Fire Protection Association
(e.g. NFPA 25), in addition to the standards of any other
authorities having jurisdiction.
Refer to Globe’s Residential Installation Guide for further
Care and Maintenance information.

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.
