High Pressure Sprinklers
Quick and Standard Response
Model SG300
GENERAL DESCRIPTION
The Star Model SG300 Sprinklers are automatic sprin-
klers of the frangible bulb type. Their maximum service
pressure rating of 300 psi (20,7 bar) makes them an ex-
cellent choice for systems that otherwise would require
the use of pressure control valves to reduce the static
pressure to 165 psi (11,4 bar) as required by NFPA stand-
ards, when conventional 175 psi (12,1 bar) maximum
pressure rated sprinklers are utilized. One of the most
common applications for the SG300 Sprinklers is fire pro-
tection systems for high rise buildings.
WARNINGS
The Model SG300 Sprinklers described herein must be in-
stalled 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.
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.

DESIGN CRITERIA
The Model SG300 Sprinklers are to be utilized for the
same applications as intended for the 175 psi (12,1 bar)
counterparts described in the cross referenced Star Data
Sheets indicated in Table A. Recessed versions of the
Model SG300 having up to a maximum temperature rat-
ing of 200°F/93°C are obtained by utilizing the #2085 Re-
cessed Escutcheon as described in the applicable cross
referenced Star Data Sheets.
INSTALLATION
Installation of the Model SG300 Sprinklers is to be the
same as the 175 psi (12,1 bar) counterparts described in
the cross referenced Star Data Sheets indicated in Table
A.
CARE AND MAINTENANCE
The Model SG300 Sprinklers must be maintained and
serviced in accordance with the following instructions:
NOTE
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
Absence of an escutcheon, which is used to cover a clear-
ance hole, may delay the time to sprinkler operation in a
fire situation.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified sprinklers must
be replaced. Sprinklers that have been exposed to corro-
sive products of combustion, but have not operated,
should be replaced if they cannot be completely cleaned
by wiping the sprinkler with a cloth or by brushing it with a
soft bristle brush.
Care must be exercised to avoid damage to the sprinklers
— before, during, and after installation. Sprinklers dam-
aged by dropping, striking, wrench twist/slippage or the
like, must be replaced. Also, replace any sprinkler that
has a cracked bulb or that has lost liquid from its bulb
(ref. Installation Section Note).
The owner is responsible for the inspection, testing, and
maintenance of their fire protection system and devices in
compliance with this document, as well as with the appli-
cable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
