PENDENT & UPRIGHT SPRINKLERS , STD. COVERAGE
MODEL F892 DESIGNER
STANDARD RESPONSE, K=11.2 , 3/4"NPT **
GENERAL DESCRIPTION
The 11.2 K-Factor Model F892 De-
signer, Standard Response, Standard
Coverage, Pendent and Upright Sprin-
klers (Ref. Figure A) are automatic
sprinklers of the frangible bulb type.
They are “standard response - spray
sprinklers” which produce a hemi-
spherical water distribution pattern be-
low the deflector.
The F892 Sprinklers are intended for
use in fire sprinkler systems designed
in accordance with the standard instal-
lation rules recognized by the applica-
ble Listing or Approval agency (e.g.,
UL Listing is based on the require-
ments of the National Fire Protection
Association). Also, when acceptable
to the Authority Having Jurisdiction,
they may be used with a “Reduced
Design Area” as indicated in Table A.
The 11.2 K-Factor F892 Sprinklers
were subjected to full scale, high-piled
storage, fire tests to qualify their use in
lieu of 5.6 or 8.0 K-Factor standard
spray sprinklers for the protection of
high-piled storage.
Higher flow rates can be achieved at
much lower pressures with the 11.2
K-Factor F892 Sprinklers — making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
The 11.2 K-Factor F892 Sprinkler also
has the advantage of having a specific
application listing, which in some
cases can subsequently reduce the
design area and the overall water de-
mand of the sprinkler system. Refer to
Table A for details.
Wax, lead, or polyester coatings can
be used to extend the life of the copper
alloy components used in Model F892
sprinklers beyond that which would
otherwise be obtained when exposed
to corrosive atmospheres. Although
wax, lead, and polyester coated sprin-
klers have passed the standard corro-
sion tests of the applicable approval
agencies, the testing is not repre-
sentative of all possible corrosive at-
mospheres. Consequently, it is recom-
mended that the end user be consulted

with respect to the suitability of these
corrosion resistant coatings for any
given corrosive environment. The ef-
fects of ambient temperature, concen-
tration of chemicals, and gas/chemical
velocity, should be considered, as a
minimum, along with the corrosive na-
ture of the chemical to which the sprin-
klers will be exposed.
APPROVALS AND STANDARDS
Laboratory listings and approvals for
the 11.2 K-Factor, Model F892 De-
signer, Standard Response, Standard
Coverage, Pendent and Upright Sprin-
klers are given in Table A.
WARNING
The 11.2 K-Factor, Model F892 Pen-
dent and Upright Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the appli-
cable 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 de-
vices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
manufacturer should be contacted
relative to any questions.
Installation of Model F892 Pendent
Sprinklers in recessed escutcheons
will void all sprinkler warranties, as
well as possibly void the sprinklers
Approvals and/or Listings.
TECHNICAL DATA
The 11.2 K-Factor, Model F892 De-
signer, Standard Response, Standard
Coverage, Pendent and Upright
Sprinklers are rated for use at a maxi-
mum service pressure of 175 psi (12,1
bar). They are available in the tem-
perature ratings and finishes indicated
in Table A.
The nominal flow “Q” in GPM (LPM) is
determined by the following formula:
where the nominal sprinkler discharge
coefficient “K” = 11.2 (161,3) and “p”
equals the residual flowing pressure in
psi (bar).
The Frame of the Model F892 Sprin-
klers, (Ref. Figure A), is a dezincifica-
tion resistant bronze. The Button is
bronze, and the Gasketed Spring Plate
is sealed on both its inside and outside
faces with a Teflon  gasket. The Com-
pression Screw and the Deflector are
brass. The standard response Model
F892 Sprinklers utilize a 5 mm diame-
ter frangible bulb. Table A indicates
the bulb liquid color as a function of
temperature rating.
NOTES
Inquiries concerning the appropriate-
ness of wax, lead, or polyester coated
sprinklers for a given corrosive envi-
ronment should be submitted to the
attention of the Technical Services
Department.
Wax, lead, or polyester coated sprin-
klers are not suitable for use in open
sprinkler corrosive environments.
INSTALLATION
NOTE
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the
sprinkler held horizontal, a small air
bubble should be present. The diame-
ter of the air bubble is approximately
1/16 inch (1,6 mm) for the
135°F/57°C to 3/32 inch (2,4 mm) for
the 286°F/141°C rating.
The Model F892 Sprinklers must be
installed in accordance with the follow-
ing instructions.
1. With pipe thread sealant applied to
the pipe threads, hand tighten the
F892 Sprinkler into the sprinkler fit-
ting.
2. Using the W-Type 3 (End A) Sprin-
kler Wrench (Ref. Fig. B) applied to
the sprinkler Wrench Flats (Ref. Fig.
A), tighten the F892 Sprinkler into
the sprinkler fitting.
NOTE
A leak tight 3/4 inch NPT sprin-
kler joint should be obtained with
a torque of 10 to 20 ft.lbs. (13,4 to
26,8 Nm). Higher levels of torque
may distort the sprinkler inlet
with consequent leakage or im-
pairment of the sprinkler.
CARE AND MAINTENANCE
Model F892 Sprinklers must be main-
tained and serviced in accordance
with the following instructions:
NOTES
Before closing a fire protection system
control valve for maintenance work
on the fire protection system which it
controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated
or otherwise altered after leaving the
factory. Modified sprinklers must be
replaced. Sprinklers that have been
exposed to corrosive products of com-
bustion, but have not operated, should
be replaced if they cannot be com-
pletely cleaned by wiping the sprinkler
with a cloth or by brushing it with a soft
bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers — before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed. Also, replace any sprinkler that
has a cracked bulb or that has lost
liquid from its bulb (ref. Installation
Section Note).
Frequent visual inspections are rec-
ommended to be initially performed for
wax and/or lead coated sprinklers, af-
ter the installation has been com-
pleted, to verify the long term potential
integrity of the sprinkler coatings.
Thereafter, annual inspections per
NFPA 25 should suffice; however, in-
stead of inspecting from the floor level,
a random sampling of close-up visual
inspections should be made, so as to
better determine the exact sprinkler
condition and the long term integrity of
the wax and/or lead coating, as it may
be affected by the corrosive conditions
present.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other

sprinkler systems be inspected,
tested, and maintained by a qualified
