Series ELO-231 – 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
TYCO Series ELO-231 11.2K Stan-
dard Response, Standard Coverage
Upright and Pendent Sprinklers (Ref.
Figure 1) are automatic sprinklers of
the fusible solder type. They are stan-
dard response, spray sprinklers that
produce a hemispherical water distri-
bution pattern below the deflector.
The 11.2 K-factor, ELO-231 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, ELO-231 Sprinklers, making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
Wax or lead coatings can be used
to extend the life of the copper alloy
components used in Series ELO-231
sprinklers beyond that which would
otherwise be obtained when exposed
to corrosive atmospheres. Although
wax and lead coated sprinklers have
passed the standard corrosion tests of
the applicable approval agencies, the
testing is not representative of all pos-
sible corrosive atmospheres. Conse-
quently, it is recommended that the end
user be consulted with respect to the
suitability of these corrosion resistant
coatings for any given corrosive envi-

Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

ronment. The effects of ambient tem-
perature, concentration of chemicals,
and gas/chemical velocity, should be
considered, as a minimum, along with
the corrosive nature of the chemical to
which the sprinklers will be exposed.
An upright intermediate level version
of the Series ELO-231 Sprinklers for
in-rack applications can be obtained
by utilizing the Series ELO-231 Upright
Sprinkler with the WSG-2 Guard &
Shield, and a pendent intermediate
level version of the Series ELO-231
Sprinklers can be obtained by utilizing
the Series ELO-231 Pendent Sprinkler
with the WS-2 Shield. If there is a pos-
sibility of the pendent intermediate level
version being exposed to mechanical
damage, a G-2 Guard can be added.
