Series ELO-231B — 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
The 11.2 K-factor, Series ELO-231B,
Standard Response, Standard Cover-
age, Upright and Pendent Sprinklers
(Ref. Figure 1) are automatic sprin-
klers of the frangible bulb type. They
are "standard response - spray sprin-
klers" that produce a hemispherical
water distribution pattern below the
deflector.
The 11.2 K-factor, ELO-231B Sprin-
klers were subjected to full scale, high-
piled storage, fire tests to qualify their
use in lieu of 5.6 or 8.0 K-factor stand-
ard 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-231B Sprinklers —
making their use highly advantageous
in high density applications, such as
the protection of high-piled storage.
Wax or lead coatings can be used to
extend the life of the copper alloy com-
ponents used in Series ELO-231B
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-
IMPORTANT
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 in-
stallation 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.

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.
An upright intermediate level version
of the Series ELO-231B Sprinklers for
in-rack applications can be obtained
by utilizing the Series ELO-231B Up-
right Sprinkler with the WSG-2 Guard
& Shield, and a pendent intermediate
level version of the Series ELO-231B
Sprinklers can be obtained by utiliz-
ing the Series ELO-231B Pendent
Sprinkler with the WS-2 Shield. If there
is a possibility of the pendent interme-
diate level version being exposed to
mechanical damage, a G-2 Guard can
be added.
