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
