Series ELO-231FRB — 11.2 K-factor
Upright and Pendent Sprinklers
Quick Response, Standard Coverage

ELO-231FRB Pendent Sprinkler with

General
Description

The 11.2 K-factor, Series ELO­231FRB, Quick Response, Standard
Coverage,Upright and Pendent Sprin­klers (Ref. Figure 1) are automati c
sprinklers of the frangible bulb type.
They are “quick response - spray
sprinklers” that produce a hemispheri­cal water distributionpatternbelowthe
deflector.

The 11.2 K-factor, ELO-231FRB Up­right and Pendent Sprinklers were
subjected to full scale, high-piled stor­age,fireteststoqualifytheiruseinlieu
of 5.6 or 8.0 K-factor standard spray
sprinklers for the protection of high­piled storage.

Higher flow rates can be achieved at
much lower pressures with the 11.2
K-factor, ELO-231FRB Sprinklers —
making their use highly advantageous
in high density applications, such as
the p rotection of high-piled storage.

For in-rack applications an upright in­termediate level version of the Series
ELO-231FRB Sprinklers can be ob­tained by utilizing the Series ELO­231FRB Upright Sprinkler with the
WSG-2Guard&Shield,andapendent
intermediate level version of the Se­ries ELO-231FRB Sprinklers can be
obtained by utilizing the Series

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
tooperatein a firesituation or cause
it to operate prematurely.

theWS-2Shield.Ifthereis 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 ELO­231FRB Upright and Pendent Sprin­klers described her ein must be in­stalled and maintained in compliance
with this document, as well as with the
applicable standards of the National
FireProtectionAssociation, in addition
to the standards of any other authori­ties having jurisdiction. Failure to do

so may impai r the perform ance of
these devices.

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

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

Design Criteria

Requirements

The 11.2 K- factor, Model ELO­231FRB (TY5131 & TY5231) Sprin­klers are to be installed in accordance
with NFPA 13 standard sprinkler posi­tion and area/density flow calculation
requirements for light, ordinary, or ex­tra hazard occupancies, as well as
high piled storage occupancies (solid
piled, palletized,rackstorage,bin box,
and shelf storage including but not lim­itedtoClassI-IVand GroupAplastics)
with a minimum residual (flowing)
pressure of 7 psi (0,5 bar) for wet pipe
systems only.

FM Approval
Requirements

The 11.2 K- factor, Model ELO­231FRB (TY5131 & TY5231) Sprin­klers are to be installed in accordance
with the applicable “control mode den­sity/area” guidelines provided by Fac­tory Mutual for wet systems only. (FM
guidelines may differ from UL and C­UL Listing criteria.)

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.

Installation

The Series ELO-231FRB Sprinklers
must be installed in accordance with
the following instructions:

NOTES

Do not install any bulb type sprinkler if
the bulb is cracked or thereis a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
shouldbe present.The diameterof the
air bubble is approximately 1/16 inch
(1,6 mm) for the 155°F/68°C to 3/32
inch (2,4 mm ) for the 286°F/141°C
temperature ratings.

A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). A maxi­mum of 30 ft.lbs. (40,7 Nm) of torque
is to be used to install sprinklers with
3/4 NPT connections. Higher levels of
torque may distort the sprinkler inlet
and cause 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. Readjust the position of the
sprinkler fitting to suit.

The Series ELO-231FRB 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 thr ead sealant ap-
