Series ELO-231
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
The 11.2 K-factor, Series ELO-231,
Standard Response, Standard Cover-
age, Upright and Pendent Sprinklers
(Ref. Figure 1) are automatic sprin-
klers of the fusible solder type. They
are "standard response - spray sprin-
klers" that produce a hemispherical
water distribution 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 — mak-
ing 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-231 sprin-
klers beyond that which would other-
wise 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-
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.

sible corrosive atmospheres. Conse-
quently, it is recommended that the
end user be consulted with respect to
the suitability of these corrosion resis-
tant coatings for any given corrosive
environment. The effects of ambient
temperature, concentration of chemi-
cals, 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 Up-
right Sprinkler with the WSG-2 Guard
& Shield, and a pendent intermediate
level version of the Series ELO-231
Sprinklers can be obtained by utiliz-
ing the Series ELO-231 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.
WARNINGS
The 11.2 K-factor, Series ELO-231
Upright and Pendent Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the performance of these de-
vices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or manufac-
turer should be contacted with any
questions.
Installation of Series ELO-231 Pen-
dent Sprinklers in recessed escutch-
eons will void all sprinkler warranties,
as well as possibly void the sprinkler's
Approvals and/or Listings.
