PENDENT & UPRIGHT SPRINKLERS , STD. COVERAGE
MODEL F892 DESIGNER
STANDARD RESPONSE, K=16.8 , 3/4"NPT **
GENERAL DESCRIPTION
The 16.8 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 16.8 K-Factor F892 Sprinklers
were subjected to full scale, high-piled
storage, fire tests to qualify their use in
lieu of 8.0 or 11.2 K-Factor standard
spray sprinklers for the protection of
high-piled storage.
Higher flow rates can be achieved at
much lower pressures with the 16.8
K-Factor F892 Sprinklers — making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
The 16.8 K-Factor F892 Sprinkler also
has the advantage of having a UL and
C-UL specific application listing, which
in some cases can subsequently re-
duce the design area and the overall
water demand of the sprinkler system.
Refer to Table A for details.
Applications for the 16.8 K-Factor
Model F892 Pendent and Upright
Sprinklers are expanding beyond the
current listings/approvals. For infor-
mation regarding research fire tests
which may be acceptable to an Author-
ity Having Jurisdiction, please contact
the Technical Services Department.
APPROVALS AND STANDARDS
Laboratory listings and approvals for
the 16.8 K-Factor, Model F892 De-
signer, Standard Response, Standard
Coverage, Pendent and Upright Sprin-
klers are given in Table A.
WARNING
The 16.8 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.

TECHNICAL DATA
The 16.8 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” = 16.8 (241,9) 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.

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
155°F/68°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 8 Sprinkler
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).
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
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
