Residential Horizontal Sidewall and
Recessed Hor. Sidewall Sprinklers
Star Galaxy™ SG-RES, K=4.3 & 5.8
GENERAL DESCRIPTION
The Star Galaxy SG-RES Residential Horizontal Sidewall
and Recessed Horizontal Sidewall Sprinklers are decora-
tive glass bulb sprinklers designed for use in residential
occupancies such as homes, apartments, dormitories,
and hotels.
They are to be used in wet pipe residential sprinkler sys-
tems for one- and two-family dwellings and mobile homes
per NFPA 13D; wet pipe residential sprinkler systems for
residential occupancies up to and including four stories in
height per NFPA 13R; or, wet pipe sprinkler systems for
the residential portions of any occupancy per NFPA 13.
The Star Galaxy SG-RES is provided with K-Factors of
4.3 (61,9) or 5.8 (83,5) to provide the system designer
with flexibility for coverage areas and hydraulic options.
They are designed for installation along a wall or lintel
and just beneath a smooth and level ceiling. Sidewall
sprinklers are generally used in lieu of ceiling sprinklers
because of either aesthetic or building construction con-
siderations.
The recessed version of the Star Galaxy SG-RES using a
#2084 Recessed Escutcheon provides 1/4 inch (6,4 mm)
of recessed adjustment or up to 1/2 inch (12,7 mm) of to-
tal adjustment from the flush sidewall position.
The Star Galaxy SG-RES has been designed with heat
sensitivity and water distribution characteristics proven to
help in the control of residential fires to improve the
chance for occupants to escape or be evacuated. How-
ever, residential fire sprinkler systems are not a substitute
for intelligent fire safety awareness or fire safety construc-
tion required by building codes.
WARNINGS
The Star Galaxy SG-RES Residential Horizontal Side-
wall and Recessed Horizontal Sidewall Sprinklers de-
scribed herein must be installed and maintained in
compliance with this document, as well as with the
applicable standards of the National Fire Protection
Association, in addition to the standards of any other
authorities having jurisdiction. Failure to do so may
impair the integrity of these devices.
Because of the above cited stipulations and the var-
ied nature of residential type architecture, there will
be some compartment designs which cannot be fully
sprinklered in accordance with the recommendations
of NFPA 13, 13D, or 13R. In the event of this condi-
tion, consult the authorities having jurisdiction for
guidance and approval.
It is the responsibility of the installing contractor to
provide a copy of this document to the owner or his
representative, and in turn, it is the obligation of the
owner to provide a copy of this document to a suc-
ceeding owner.
The owner is responsible for maintaining their fire
protection system and devices in proper operating
condition. The installing contractor or sprinkler manu-
facturer should be contacted relative to any ques-
tions.
OPERATION
The glass bulb contains a fluid which expands when ex-
posed to heat. When the rated temperature is reached,
the fluid expands sufficiently to shatter the glass bulb,
which then allows the sprinkler to activate and flow water.
