GENERAL DESCRIPTION
The series GL-RES pendent sprinklers are decorative fast
response glass bulb sprinklers specifically tested and List
-
ed for use in residential applications such as homes, apart-
ments, hotels, and dormitories to provide control of these
residential type fires and to improve the chance for occu
-
pants to escape. They utilize a 3mm frangible glass bulb as
its heat sensing operating element. The recessed version
of each of these Residential Sprinklers is intended for use
in areas with finished ceilings. It employs a two-piece Re
-
cessed Escutcheon. The Recessed Escutcheon provides a
total adjustment of 1/2 inch (12.7mm) from the flush ceiling
position or ±1/4 inch (6.4mm) of recessed adjustment. The
adjustment provided by the Recessed Escutcheon reduces
the accuracy to which the pipe drops to the sprinklers must
be cut.
This sprinkler may be installed within dwelling occupancies
as allowed by NFPA 13, 13D, 13R and any other related
documents as appropriate.
The GL3010 is typically utilized when maximum coverag
-
es are not needed, thereby reducing flow demands. The
GL5610 is typically the sprinkler of choice when utilizing
Residential Sprinklers within an NFPA 13 Occupancy. The
larger K-factor can be advantageous when needed to con-
form to the NFPA 13 hydraulic Special Design Approach for
Residential Sprinklers.
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.
