General
Description
TYCO Series ELO-231 11.2K Standard Response, Standard Coverage
Upright and Pendent Sprinklers (Ref.
Figure 1) are automatic sprinklers of
the fusible solder type. They are standard response, spray sprinklers 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, 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-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 possible corrosive atmospheres. Consequently, 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 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.
ronment. 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-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 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-231
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

its rated temperature, the ball is forced
upward into the center strut, releasing the two ejectors and operating the

Installation
TYCO Series ELO-231 11.2K Standard Response, Standard Coverage
Upright and Pendent Sprinklers must
be installed in accordance with this
section.
A leak-tight 3/4 in. NPT sprinkler joint
should be obtained by applying a minimum-to-maximum torque of 10 to
20 lb-ft (13,4 to 26,8 N∙m). A leaktight 1/2 in. NPT sprinkler joint should
be obtained by applying a minimumto-maximum torque of 7 to 14 lb-ft
(9,5 to 19,0 N∙m). Higher levels of
torque can distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to make up for insufficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Re-adjust the position of the
sprinkler fitting to suit.
The Series ELO-231 Upright and
Pendent Sprinklers must be installed
in accordance with the following
instructions:
Step 1. Pendent sprinklers are to be
installed in the pendent position, and
upright sprinklers are to be installed in
the upright position.
Step 2. With pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
3 Sprinkler Wrench (Ref. Figure 2),
except that an 8 in. or 10 in. adjustable Crescent wrench is to be used
for wax coated sprinklers. With reference to Figure 1, the W-Type 3 Sprinkler Wrench or the adjustable wrench,
as applicable, is to be applied to the
wrench flats.
When installing wax-coated sprinklers
with the adjustable wrench, additional
care needs to be exercised to prevent
damage to the wax coating on the
sprinkler wrench flats or frame arms
and, consequently, exposure of bare
metal to the corrosive environment.
The jaws of the wrench should be
opened sufficiently wide to pass over
the wrench flats without damaging the
wax coating. Before wrench-tightening
the sprinkler, the jaws of the wrench are
to be adjusted to just contact the sprinkler wrench flats. After wrench-tightening the sprinkler, loosen the wrench
jaws before removing the wrench.
After installation, the sprinkler
wrench flats and frame arms must
be inspected and the wax coating
re-touched (repaired) whenever the
coating has been damaged and bare
metal is exposed. The wax coating on
the wrench flats can be retouched by
gently applying a heated 1/8 in. diameter steel rod to the areas of wax that
have been damaged, to smooth it
back over areas where bare metal is
exposed.
Note:
Only reto uching of the wax c oating
applied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed only at the time of
the initial sprinkler installation.
The steel rod should be heated only
to the point at which it can begin to
melt the wax, and appropriate precautions need to be taken, when handling
the heated rod, in order to prevent the
installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuccessful, additional wax can be ordered
in the form of a wax stick (the end of
which is color coded). Only the correct
color-coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time
of initial sprinkler installation. With
the steel rod heated as previously
described, touch the rod to the area
requiring additional wax with the rod
angled downward, and then touch
the wax stick to the rod approximately
1/2 in. away from the area requiring
retouching. The wax will melt and run
down onto the sprinkler.
Care and
Maintenance
TYCO Series ELO-231 11.2K Standard
Response, Standard Coverage Upright
and Pendent Sprinklers must be maintained and serviced in accordance with
this section.
Before closing a fire protection system
control valve for maintenance work on
the fire protection system that it controls, permission to shut down the
affected fire protection system must
be obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modified or over-heated sprinklers must be
replaced.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprinklers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced.
Frequent visual inspections are recommended to be initially performed
for corrosion resistant sprinklers, after
the installation has been completed, to
verify the long term potential integrity
of the sprinkler coatings. Thereafter,
annual inspections per NFPA 25 should
suffice; however, instead of inspecting
from the floor level, a random sampling
of close-up visual inspections should
be made, so as to better determine the
exact sprinkler condition and the long
term integrity of the corrosion resistant
coating, as it may be affected by the
corrosive conditions present.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Association, such as NFPA 25, in addition to
the standards of any other authorities
having jurisdiction. Contact the installing contractor or product manufacturer
with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspection Service in accordance with local
requirements and/or national codes.

The wax used for 286°F (141°C)
sprinklers is the same as for 212°F
(100°C) sprinklers, and, therefore, the
