PENDENT & UPRIGHT SPRINKLERS , STD. COVERAGE
MODEL F892QR DESIGNER
QUICK RESPONSE, K=11.2 , 3/4"NPT **
GENERAL DESCRIPTION
The 11.2 K-Factor Model F892QR De-
signer, Quick Response, Standard
Coverage, Pendent and Upright Sprin-
klers (Ref. Figure A) are automatic
sprinklers of the frangible bulb type.
They are “quick response - spray
sprinklers” which produce a hemi-
spherical water distribution pattern be-
low the deflector.
The F892QR Sprinklers are intended
for use in fire sprinkler systems de-
signed in accordance with the stand-
ard installation rules recognized by the
applicable Listing or Approval agency
(e.g., UL Listing is based on the re-
quirements of the National Fire Protec-
tion Association). Also, when accept-
able
to
the
Authority
Having
Jurisdiction, they may be used with a
“Reduced Design Area” as indicated in
Table A.
The 11.2 K-Factor F892QR 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 F892QR Sprinklers — mak-
ing their use highly advantageous in
high density applications, such as the
protection of high-piled storage.
The 11.2 K-Factor F892QR 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
demand 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

used
in
Model
F892QR sprinklers beyond that which
would otherwise be obtained when ex-
posed to corrosive atmospheres. Al-
though
wax,
lead,
and
polyester
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently, it
