General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Horizontal Sidewall
Sprinklers (TY2334) are decorative,
fast response, frangible bulb sprinklers
designed for use in residential occu-
pancies such as homes, apartments,
dormitories, and hotels. When aesthet-
ics and optimized flow characteristics
are the major consideration, the Series
LFII Residential Sprinklers (TY2334)
should be the first choice.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet pipe residential sprinkler sys-
tems for one-and two-family dwell-
ings and mobile homes per NFPA
13D
• wet pipe residential sprinkler sys-
tems for residential occupancies up
to and including four stories in height
per NFPA 13R
• wet pipe sprinkler systems for the
residential portions of any occu-
pancy per NFPA 13
The recessed version of the Series
LFII Residential Sprinklers is intended
for use in areas with finished walls.
It employs a two-piece Style 20
Recessed Escutcheon. The Recessed
Escutcheon provides 1/4 in. (6,4 mm)
of recessed adjustment or up to 1/2 in.
(12,7 mm) of total adjustment from the
flush mounting surface position. The
adjustment provided by the Recessed
Escutcheon reduces the accuracy to
which the pipe nipples to the sprinklers
must be cut.
The Series LFII Residential Sprinklers
has been designed with heat sensitivity
and water distribution characteristics
proven to help in the control of residen-
tial fires and to improve the chance for
occupants to escape or be evacuated.
NOTICE
The Series LFII Residential Horizontal
Sidewall Sprinklers (TY2334) described
herein must be installed and main-
tained in compliance with this docu-
ment and with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, in addition to the stan-
dards of any authorities having jurisdic-
tion. Failure to do so may impair the
performance of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

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 acti-
vate and flow water.
Design
Criteria
The TYCO RAPID RESPONSE Series
LFII (TY2334) Residential Horizontal
Sidewall Sprinklers are UL and C-UL
Listed for installation in accordance
with this section.
Residential Sprinkler Design Guide
When conditions exist that are outside
the scope of the provided criteria, refer
to the Residential Sprinkler Design
Guide TFP490 for the manufactur-
er’s recommendations that may be
acceptable to the local authority having
jurisdiction.
System Type
Only wet pipe systems may be utilized.
Ceiling Type
Smooth flat horizontal, or beamed, or
sloped, in accordance with the 2013
Edition of NFPA 13D, 13R, or 13 as
applicable.
Hydraulic Design
(NFPA 13D and 13R)
For systems designed to NFPA 13D or
NFPA 13R, the minimum required sprin-
kler flow rate are given in Table A as a
function of temperature rating and the
maximum allowable coverage areas.
The sprinkler flow rate is the minimum
required discharge from each of the
total number of design sprinklers as
specified in NFPA 13D or NFPA 13R.
Hydraulic Design
(NFPA 13)
For systems designed to NFPA 13, the
number of design sprinklers is to be
the four most hydraulically demanding
sprinklers. The minimum required dis-
charge from each of the four sprinklers
is to be the greater of the following:
• The flow rates given in Table A as a
function of temperature rating and
the maximum allowable coverage
area.
• A minimum discharge of 0.1
gpm/ft2over the “design area” com-
prised of the four most hydraulically
demanding sprinklers for the actual
coverage areas being protected by
the four sprinklers.
Obstruction to Water Distribution
Sprinklers are to be located in accor-
dance with the obstruction rules of
NFPA 13D, 13R, and 13 as applicable
for residential sprinklers as well as with
the obstruction criteria described within
the Technical Data Sheet TFP490.
Operational Sensitivity
The sprinklers are to be installed with
an end of defector-boss to wall dis-
tance of 1-1/8 in. to 6 in.
In addition the top-of-deflector-to-ceil-
ing distance is to be within the range
(Ref. Table A) being hydraulically
calculated.
Sprinkler Spacing
The minimum spacing between sprin-
klers is 8 ft (2,4 m). The maximum
spacing between sprinklers cannot
exceed the width of the coverage area
(Ref. Table A) being hydraulically calcu-
lated (e.g., maximum 12 ft for a 12 ft x
12 ft coverage area, or 16 ft for a 16 ft
x 20 ft coverage area).
Installation
The TYCO RAPID RESPONSE Series
LFII (TY2334) Residential Horizontal
Sidewall Sprinklers must be installed
in accordance with this section.
General Instructions
Do not install any bulb-type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm).
A leak-tight 1/2 in. NPT sprinkler joint
should be obtained by applying a
minimum to 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 compensate for
insufficient adjustment in the sprinkler
by under- or over-tightening the sprin-
kler. Re-adjust the position of the sprin-
kler fitting to suit.
Series LFII Residential Horizontal
Sidewall Sprinklers
The Series LFII Horizontal Sidewall
Sprinklers must be installed in accor-
dance with the following instructions.
Step 1. Horizontal sidewall sprinklers
are to be installed in the horizontal
position with their centerline of water-
way perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the Deflector is to face towards
the ceiling with the front edge of the
Deflector parallel to the ceiling.
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 6 Sprinkler Wrench (Ref. Fig-
ure 3). With reference to Figure 1, the
W-Type 6 Sprinkler Wrench is to be
applied to the wrench flats.
Series LFII Residential Recessed
Horizontal Sidewall Sprinklers
The Series LFII Recessed Horizontal
Sidewall Sprinklers must be installed
in accordance with the following
instructions.
Step A. Recessed horizontal sidewall
sprinklers are to be installed in the hor-
izontal position with their centerline of
waterway perpendicular to the back
wall and parallel to the ceiling. The
word “TOP” on the Deflector is to face
towards the ceiling.
Step B. After installing the Style 20
Mounting Plate over the sprinkler
threads and with pipe thread seal-
ant applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step C. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
7 Recessed Sprinkler Wrench (Ref. Fig-
ure 4). With reference to Figure 1, the
W-Type 7 Recessed Sprinkler Wrench
is to be applied to the sprinkler wrench
flats.
Step D. After the wall has been
installed or the finish coat has been
applied, slide on the Style 20 Closure
over the Series LFII Sprinkler and push
the Closure over the Mounting Plate
until its flange comes in contact with
the wall.

Care and
Maintenance
The TYCO RAPID RESPONSE Series
LFII (TY2334) Residential Horizontal
Sidewall Sprinklers must be maintained
and serviced in accordance with this
section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
which 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.
Absence of an Escutcheon Plate may
delay the sprinkler operation in a fire
situation.
The owner must assure that the sprin-
klers are not used for hanging any
objects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a fire or inad-
vertent operation may result.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid
damage to the sprinklers - before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. Refer to the Instal-
lation section for additional information.
The owner is responsible for the inspec-
tion, testing, and maintenance of their
fire protection system and devices in
