General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Horizontal Sidewall
Sprinklers (TY1334) are decorative,
fast response, frangible bulb sprinklers
designed for use in residential occupan-
cies such as homes, apartments, dormi-
tories, and hotels. When aesthetics and
optimized ow characteristics are the
major consideration, the Series LFII
Residential Sidewall Sprinklers (TY1334)
should be the rst choice.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
•
wet and dry pipe residential sprinkler
systems for one- and two-family
dwellings and mobile homes per
NFPA 13D
•
wet and dry pipe residential sprinkler
systems for residential occupancies
up to and including four stories in
height per NFPA 13R
•
wet and dry pipe sprinkler systems
for the residential portions of any
occupancy per NFPA 13
The recessed version of the Series
LFII Residential Sprinklers is intended
for use in areas with nished walls.
It employs a two-piece Style 20
Recessed Escutcheon. The Recessed
Escutcheon provides 1/4 inch (6,4 mm)
of recessed adjustment or up to 1/2 inch
(12,7 mm) of total adjustment from the
ush 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
have been designed with heat sensitivity
and water distribution characteristics
proven to help in the control of residen-
tial res and to improve the chance for
occupants to escape or be evacuated.
Dry Pipe System Application
The Series LFII Residential Horizontal
and Recessed Horizontal Sidewall
Sprinklers offers a laboratory approved
option for designing dry pipe residen-
tial sprinkler systems, whereas, most
residential sprinklers are laboratory
approved for wet systems only.
Through extensive testing and as refer-
enced in U.S. Patent 7,712,543, it has
been determined that the number of
design sprinklers (hydraulic design area)
for the Series LFII Residential Sprinklers
need not be increased over the number
of design sprinklers (hydraulic design
area) as specied for wet pipe sprinkler
systems, as is accustomed for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series LFII
Residential Sprinklers offer the features
of non-water lled pipe in addition to
not having to increase the number of
design sprinklers (hydraulic design area)
for systems designed to NFPA 13, 13D,
or 13R. Non-water lled pipe will permit
options for areas sensitive to freezing
NOTICE
The Series LFII Residential Horizontal
Sidewall Sprinklers described herein
must be installed and maintained in
compliance with this document and the
applicable standards of the National Fire
Protection Association, in addition to the
standards of any authorities having juris-
diction. 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 sprinkler manu-
facturer should be contacted with any
questions.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation 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.

Criteria
The TYCO RAPID RESPONSE
Series LFII Residential Horizontal
and Recessed Horizontal Sidewall
Sprinklers (TY1334) are UL and C-UL
Listed for installation in accordance
with the following criteria.
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.

pipe systems may be utilized. Per the
C-UL Listing, only wet pipe systems
may be utilized.
Refer to Technical Data Sheet TFP485
about the use of Residential Sprinklers
in residential dry pipe systems.
Hydraulic Design
(NFPA 13D and 13R)
For systems designed to NFPA 13D
or NFPA 13R, the minimum required
sprinkler ow rates are given in Tables
A, B, C, D and E as a function of
temperature rating and the maximum
allowable coverage areas. The
sprinkler ow rate is the minimum
required discharge from each of the
total number of “design sprinklers” as
specied in NFPA 13D or NFPA 13R.
The number of “design sprinklers”
specied in NFPA 13D and 13R for wet
pipe systems is to be applied when
designing dry pipe systems.
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 discharge from each of the
four sprinklers is to be the greater of
the following:
• The ow rates given in Tables A, B,
C, D, or E as a function of tempera-
ture rating and the maximum allow-
able coverage area.
• A minimum discharge of 0.1 gpm/ft2
over the “design area” comprised of
the four most hydraulically demand-
ing sprinklers for actual coverage ar-
eas protected by the four sprinklers.
The number of “design sprin-
klers” specied in NFPA 13 for wet
pipe systems is to be applied when
designing dry pipe systems.
Dry Pipe System Water Delivery
When using the Series LFII Residential
Horizontal Sidewall Sprinklers (TY1334)
in dry pipe sprinkler systems, the time
for water delivery must not exceed 15
seconds for the most remote operating
sprinkler.
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 TYCO Technical Data Sheet
TFP490.
Operational Sensitivity
The sprinklers are to be installed
with an end-of-deector-boss to wall
distance of 1-3/8 to 6 inches or in the
recessed position using only the Style
20 Recessed Escutcheon as shown in
Figure 2.
In addition the top-of-deector-to-
ceiling distance is to be within the range
(Tables A, B, C, D or E) being hydrauli-
cally calculated.
Sprinkler Spacing
The minimum spacing between sprin-
klers is 8 feet (2,4 m). The maximum
spacing between sprinklers cannot
exceed the width of the coverage area
(Tables A, B, C, D, or E) being hydrauli-
cally calculated (e.g., maximum 12 feet
for a 12 ft. x 12 ft. coverage area, or 16
feet for a 16 ft. x 20 ft. coverage area.)

Installation
The TYCO RAPID RESPONSE
Series LFII Residential Horizontal
and Recessed Horizontal Sidewall
Sprinklers (TY1334) 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 sprinkler
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 inch NPT sprinkler
joint should be obtained by applying a
minimum to maximum torque of 7 to 14
ft. lbs. (9,5 to 19,0 Nm). Higher levels
of torque can distort the sprinkler Inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate
for insufcient adjustment in an
Escutcheon Plate by under- or over-
tightening the Sprinkler. Re-adjust the
position of the sprinkler tting to suit.
Series LFII Residential Horizontal
Sidewall Sprinklers
The Series LFII Residential Horizontal
Sidewall Sprinklers must be installed
in accordance with the following
instructions.
Step 1. Install horizontal sidewall sprin-
klers in the horizontal position with their
centerline of waterway perpendicular to
the backwall and parallel to the ceiling.
The word “TOP” on the Deector is to
face towards the ceiling with the front
edge of the Deector parallel to the
ceiling.
Step 2. With pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 3. Tighten the sprinkler into the
sprinkler tting using only the W-Type
6 Sprinkler Wrench (Figure 3). With
reference to Figure 1, apply the W-Type
6 Sprinkler Wrench to the wrench ats.
Series LFII Residential Recessed
Horizontal Sidewall Sprinklers
The Series LFII Residential Recessed
Horizontal Sidewall Sprinklers must
be installed in accordance with the
following instructions.
Step A. Install recessed hori-
zontal sidewall sprinklers in the hori-
zontal position with their centerline
of waterway perpendicular to the
backwall and parallel to the ceiling. The
word “TOP” on the Deector is to face
towards the ceiling.
Step B. After installing the Style 20
Mounting Plate over the sprinkler
threads and with pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step C. Tighten the sprinkler into the
sprinkler tting using only the W-Type
7 Recessed Sprinkler Wrench (Figure
4). With reference to Figure 1, apply the
W-Type 7 Recessed Sprinkler Wrench
to the sprinkler wrench ats.
Step D. After the ceiling has been
installed or the nish coat has been
applied, slide on the Style 20 Closure
over the Series LFII Residential
Sprinkler and push the Closure over the
Mounting Plate until its ange comes in
contact with the wall.
Care and
Maintenance
The TYCO RAPID RESPONSE
Series LFII Residential Horizontal
and Recessed Horizontal Sidewall
Sprinklers (TY1334) must be maintained
and serviced in accordance with this
section:
Before closing a re protection system
main control valve for maintenance
work on the re protection system
that it controls, obtain permission to
shut down the affected re protection
systems from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the outer piece of an
escutcheon, which is used to cover
a clearance hole, can delay sprinkler
operation in a re 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 re 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 otherwise
altered after leaving the factory.
Modied 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. Sprinklers
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. (Ref. Installation
Section.)
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
(e.g., NFPA 25), in addition to the
standards of any authorities having
jurisdiction. Contact the installing
contractor or sprinkler manufacturer
regarding any questions.
Automatic sprinkler systems are recom-
mended to be inspected, tested, and
maintained by a qualied Inspection
Service in accordance with local
requirements and/or national codes.
