Tyco Fire Product Star Galaxy SG Instruction Manual

Std. Response - Std. Coverage
Upright, Pendent, and
Recessed Pendent Sprinklers
Star Galaxy™ SG, K=8.0, 3/4" NPT
GENERAL DESCRIPTION
The Star Galaxy SG, 8.0 K-Factor, Upright, Pendent, and
Recessed Pendent Sprinklers are standard response -
standard coverage, decorative glass bulb type spray
sprinklers designed for use in light, ordinary, or extra haz-
ard, commercial occupancies such as banks, hotels,
shopping malls, factories, refineries, chemical plants, etc.
The recessed version of the Star Galaxy SG, intended for
use in areas with a finished ceiling, uses a two-piece
#2086 Recessed Escutcheon. The #2086 provides 1/2
inch (12,7 mm) of recessed adjustment or up to 3/4 inch
(19,1 mm) of total adjustment from the flush pendent posi-
tion. The adjustment provided by the Recessed Escutch-
eon reduces the accuracy to which the fixed pipe drops to
the sprinklers must be cut.
Wax and lead coatings are utilized to extend the life of
copper alloy sprinklers beyond that which would other-
wise be obtained when exposed to corrosive atmos-
pheres. Although wax and lead coated sprinklers have
passed the standard corrosion tests of the applicable ap-
proval agencies, the testing is not representative of all
possible corrosive atmospheres. Consequently, it is rec-
ommended that the end user be consulted with respect to
the suitability of these corrosion resistant coatings for any
given corrosive environment. The effects of ambient tem-
perature, concentration of chemicals, and gas/chemical
velocity, should be considered, as a minimum, along with
the corrosive nature of the chemical to which the sprin-
klers will be exposed.
An intermediate level version of the Star Galaxy SG Pen-
dent Sprinkler can be obtained by utilizing the Star Gal-
axy SG Pendent Sprinkler (SIN S2811) in combination
with the Model S11 Shield described in Product Data
Sheet 1-4.2.40.
WARNINGS
The Star Galaxy SG Sprinklers described herein must be
installed and maintained in compliance with this docu-
ment, as well as with the applicable standards of the Na-
tional Fire Protection Association, in addition to the stand-
ards of any other authorities having jurisdiction. Failure to
do so may impair the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.

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.
