General
Description

The 11.2 K-factor, Series ELO-231B,
Standard Response, Standard Cover­age, Upright and Pendent Sprinklers
(Ref. Figure 1) are automatic sprin­klers of the frangible bulb type. They
are “standard response - spray sprin­klers” that produc e a hemispherical
water distribution pattern below the
deflector.

The 11.2 K-factor, ELO-231B Sprin­klersweresubjectedtofullscale,high­piled 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 sto ra ge .

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 copperalloy com­ponents used in Series ELO-231B
sprinklers beyond that which would
otherwise be obtained when exposed
to corr osiv e atmospheres. Although
wax, lead, and polyester coated sprin­klers have passed the standard corro­sion 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 instal­lation of sprinkler systems and com­ponents. Improper handling and in­stallation can permanently damage
a sprinkler system or its compo­nents and cause the sprinkler to fail
tooperateinafiresituationor cause
it to operate prematurely.

mospheres.Consequently,itisrecom­mendedthattheenduserbe consulted
with respect to the suitability of these
corrosion resistant coatings for any
given corrosive environment. The ef­fects of ambient temperature, concen­tration of chemicals, and gas/chemical
velocity, should be considered, as a
minimum, along with the corrosive na­ture of the chemicalto which the sprin­klers 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 Up­right Sprinkler with the WSG-2 Guard
& Shield, and a pendent intermediate
level version of the Series ELO-231B
Sprinklers can be obtained by utiliz­ing the Series ELO-231B Pendent
SprinklerwiththeWS-2Shield.Ifthere
is a possibility of the pendent interme­diate level version being exposed to
mechanical damage, a G-2 Guard can
be added.

WARNINGS

The 11.2 K-factor, Series ELO-231B
Upright and P endent Sprinklers de­scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica­ble standards of the National Fire Pro­tection Association, in addition to the
standardsof any other authorities hav­ing jurisdiction. Failure to do so may

impair the performance of these de­vices.

The owner is responsible for maintain­ing their fire protection system and de­vices in proper operating condition.
The installing contractor or manufac­turer should be contacted with any
questions.

Installation of Series ELO-231B Pen­dent Sprinklers in recessed escutch­eons will void all spr inkler warranties,
as well as possibly void the sprinkler’s
