Globe GL-QR Series Manual

EXTENDED COVERAGE, QUICK RESPONSE, LIGHT HAZARD
PENDENT AND RECESSED PENDENT SPRINKLER
GENERAL DESCRIPTION
Globe Series GL-QR/ECLH sprinklers are Listed Quick Re-
sponse sprinklers which utilize a 3mm frangible glass bulb
as the thermosensitive operating element. These sprinklers
are available in pendent and recessed pendent orientations.
They are Listed and Approved as Extended Coverage sprin-
klers for Light Hazard Occupancies for a maximum cover-
2
age area of 400 ft. and are to be installed in accordance
with the guidelines of the appropriate Installation Standard
being mandated by the AHJ (i.e. NFPA 13). These sprin-
klers are available with a K-factor of 5.6 (80,6), a 1/2" npt
and various temperatures and finishes as shown. Recessed
escutcheon provides a total of 3/4" vertical adjustment.
OPERATION
Upon exposure to heat such as from a fire, the fluid in the
bulb expands, compressing the air bubble within the bulb.
When the air bubble can no longer compress, the fluid ex-
pansion causes breakage of the glass bulb, resulting in re-
lease of the water seat assembly, and discharge of water
from the sprinkler.
