Series ELO-231B – 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage

General
Description

TYCO Series ELO-231B 11.2K 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 produce a hemi­spherical water distribution pattern
below the deflector.

The 11.2 K-factor, ELO-231B 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-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
components used in Series ELO-231B
Sprinklers beyond that which would
otherwise be obtained when exposed
to corrosive atmospheres. Although
wax, lead, and polyester coated sprin­klers have passed the standard corro­sion tests of the applicable approval
agencies, the testing is not repre­sentative of all possible corrosive
atmospheres. Consequently, it is rec­ommended that the end-user be con­sulted with respect to the suitability
of these corrosion resistant coatings

IMPORTANT

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 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
to operate in a fire situation or cause
it to operate prematurely.

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 chemical to 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 Sprinkler
with the WS-2 Shield. If there is a pos­sibility of the pendent intermediate level
version being exposed to mechanical
damage, a G-2 Guard can be added.

NOTICE

The 11.2 K-factor, Series ELO-231B
Upright and Pendent 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 (NFPA), in addition
to the standards of 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. Contact the installing contrac­tor or product manufacturer with any
questions.

Installation of Series ELO-231B Pendent
Sprinklers in recessed escutcheons will
void all sprinkler warranties, as well as
possibly void the sprinkler’s Approvals
and/or Listings.

Operation

The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and water to flow.
