Globe GL-QR Series Manual

EXTENDED COVERAGE, QUICK RESPONSE, LIGHT HAZARD
CONCEALED PENDENT SPRINKLERS

GENERAL DESCRIPTION

The Globe Series GL-QR/INCH/ECLH sprinkler is a Listed
Quick Response concealed sprinkler which utilizes a 3mm
frangible glass bulb as the thermosensitive operating ele-
ment. It is Listed and Approved as an Extended Coverage
sprinkler for Light Hazard Occupancies for a maximum cov-
erage area of 400 sq. ft. and is to be installed in accordance
with the guidelines of the appropriate Installation Standard
being mandated by the AHJ (i.e. NFPA 13). While providing
the optimal aesthetic appeal with the low profile flat cover
plate, the GL-QR/INCH/ECLH additionally provides the larg-
est vertical adjustment in the industry of a nominal 1". This
nominal 1" adjustment allows for previously unrecognized
Installation flexibility resulting in a clean and tight final "fit" to
the ceiling. The sprinkler is available in three temperatures
and the cover plate is available in two temperatures. The
nominal K-Factor is 5.6 (80,6) and the threads are 1/2" npt.

OPERATION

The soldered cover plate drops off the retainer assembly
when exposed to heat, as from a fire, that has reached the
plate's Listed temperature rating exposing the sprinkler
above. Upon the releasing of the cover plate, the deflector,
which is connected to two guide pins, drops down below
the ceiling into its intended position. As heat encompasses
the glass bulb operating element of the sprinkler, the fluid
in the bulb expands, compressing the air bubble within the
bulb. When the air bubble can no longer compress, the fluid
expansion causes breakage of the glass bulb, resulting in
release of the water seat assembly, and discharge of water
from the sprinkler.
