General
Description
The TYCO RAPID RESPONSE Series LFII
Dry-Type Residential Horizontal Sidewall
Sprinklers (TY2335) are decorative,
fast response, frangible bulb sprinklers
designed for use in residential occu-
pancies such as homes, apartments,
dormitories, and hotels. When aesthetics
and optimized ow characteristics are
the major consideration, the Series LFII
Sprinklers (TY2335) should be the rst
choice. These sprinklers may be used in
wet pipe, dry pipe, or preaction systems.
Residential sprinklers listed for dry pipe or
preaction systems must undergo special
testing at Underwriters Laboratories,
Inc., including a 15-second delay while
passing all UL1626 test criteria. The
sprinklers described in this data sheet
have undergone this special UL testing
and are therefore listed for the types of
residential designs cited below.
Dry-Type Sprinklers are typically used
where:
• sprinklers are required on dry pipe
systems that are exposed to freezing
temperatures; for example, sprin-
kler drops from unheated portions of
buildings.
• sprinklers and/or a portion of the con-
necting piping are exposed to freezing
temperatures; for example, sprinkler
drops from wet systems into unheat-
ed areas.
• sprinklers are used on systems that are
seasonally drained to avoid freezing;
for example, vacation areas.
The Series LFII Dry-Type Residential Hori-
zontal Sidewall Sprinklers are intended
for use in Residential Sprinkler systems
for one- and two-family dwellings and
mobile homes per NFPA 13D; residential
sprinkler systems for residential occu-
pancies up to and including four stories
in height per NFPA 13R; or, sprinkler
systems for the residential portions of
any occupancy per NFPA 13.
These sprinklers have a 4.4 (63,4) K-factor
that provides the required residential ow
rates at reduced pressures, supporting
smaller pipe sizes and water supply
requirements.
The recessed version 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 adjust-
ment from the ush mounting surface
position. The design of this escutcheon
provides a level of exibility in adjusting
sprinklers to xed pipe drops.
The Series LFII Dry-Type Residential
Horizontal Sidewall Sprinklers are de-
signed with heat sensitivity and water
characteristics proven to help in control-
ling residential res and improving the
chance for occupants to escape or be
evacuated.
NOTICE
The Series LFII Dry-Type Residential
Horizontal Sidewall Sprinklers (TY2335)
described herein must be installed and
maintained in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protection
Association, in addition to the standards
of any authorities having jurisdiction.
Failure to do so may impair the perfor-
mance of these devices.
Owners are responsible for maintaining
their fire protection system and devices in

Operation
When the TYCO Series LFII Dry-Type
Residential Horizontal Sidewall Sprinkler
is in service, water is prevented from
entering the assembly by the Plug with
Sealing Assembly (Figure 1) in the Inlet
of the Sprinkler.
The glass Bulb contains a uid that ex-
pands when exposed to heat. When the
rated temperature is reached, the uid
expands sufciently to shatter the glass
Bulb then release the Bulb Seat. System
water or air pressure then unseats the
Plug with Sealing Assembly. The Plug
Spring turns the Plug with Sealing As-
sembly aside, allowing the sprinkler to
activate and ow water.

Design
Criteria
The TYCO Series LFII Dry-Type Resi-
dential Horizontal Sidewall Sprinklers
(TY2335) are UL Listed for installation
in accordance with the criteria listed in
this section.
When conditions exist that are outside
the scope of the criteria provided in this
section, refer to the technical data sheet
entitled Residential Sprinkler Design
Guide (TFP490) for the manufacturer’s
recommendations that may be acceptable
to the local authority having jurisdiction.
This section describes the following
design characteristics:
•System Types
•Water Delivery
•Hydraulic Design
•Obstruction to Water Distribution
•Operational Sensitivity
•Sprinkler Spacing
•Sprinkler Fitting
•Prevention of Branch Line Freezing
System Types
Wet pipe, dry pipe, and preaction sys-
tems may be utilized.
Water Delivery
For dry pipe and preaction systems, water
delivery to the most remote sprinkler for
a residential hazard shall not exceed 15
seconds as dened in Section 8.3.4.3 of
the 2010 edition of NFPA 13D or Section
7.2.3.6.3 of the 2010 edition of NFPA 13.
Using the TYCO SPRINKFDT Water
Delivery Calculation Program can help
determine whether required delivery
times will likely be achieved prior to
performing the actual installation.
As an alternative to using a UL Listed
water delivery calculation program and
method, as referenced in NFPA 13D
or NFPA 13, using an inspector's test
connection is required to provide ow
equivalent to the smallest orice sprin-
kler, wherein the test orice is located
on the end of the pipe supplying the
most remote sprinkler.
Hydraulic Design
Table A lists the minimum required sprin-
kler ow rate for systems designed to
NFPA 13D or NFPA 13R as a function
of temperature rating and the maximum
allowable coverage areas. The sprinkler
ow rate is the minimum required dis-
charge from each of the total number
of “design sprinklers,” as specied in
NFPA 13D or NFPA 13R.
For systems designed to NFPA 13, the
number of required design sprinklers is
the four most hydraulically demanding
sprinklers. The minimum required dis-
charge from each of the four sprinklers
is the greater of the following:
• ow rates listed in Table A for NFPA
13D and 13R as a function of tempera-
ture rating and the maximum allowable
coverage area.
• minimum discharge of 0.1 GPM/sq.
ft. over the design area comprised of
the four most hydraulically demand-
ing sprinklers for the actual coverage
areas protected by four sprinklers.
Obstruction to Water Distribution
Sprinklers are to be located in accor-
dance with the obstruction rules of NFPA
13 for residential sprinklers as well as
with the obstruction criteria described
in technical data sheet TFP490.
Operational Sensitivity
The sprinkler must be located relative
to the mounting surface as shown in
Figures 2 and 3.
Sprinkler Spacing
The minimum lateral spacing between
sprinklers is 8 feet (2,4 m). The maximum
lateral spacing between sprinklers cannot
exceed the length of the hydraulically-
calculated coverage area (refer to Table
A); for example, a maximum of 12 feet
for a 12 ft. x 12 ft. coverage area or 18
feet for a 18 ft. x 20 ft. coverage area.
Sprinkler Fittings
Install the 1-inch NPT Series LFII Dry-
Type Residential Horizontal Sidewall
Sprinklers in the 1-inch NPT outlet or
run of one of the following ttings:
• malleable or ductile iron threaded tee
ttings that meet the dimensional re-
quirements of ANSI B16.3 (Class 150).
• cast iron threaded tee ttings that
meet the dimensional requirements
of ANSI B16.4 (Class 125).
For dry pipe system installations, only
use the side outlet of maximum 2-1/2
inch reducing tees when locating the
Series LFII Dry-Type Residential Sprin-
klers directly below the branch line.
Otherwise, use the conguration shown
in Figure 6 to assure complete drainage
from above the Series LFII Sprinklers
and the branch line.
Do not install the LFII Series Dry-Type
Residential Sprinklers into elbow ttings.
The Inlet of the sprinkler can contact the
interior of the elbow, potentially damag-
ing the Inlet seal.
Typically, the end sprinkler tting on
a branch line is plugged as shown in
Figure 7.
The Series LFII Dry-Type Sprinklers can
also be installed in the 1-inch NPT outlet
of a GRINNELL Figure 730 Mechanical
Tee. However, the use of the Figure 730
for this arrangement is limited to wet
pipe systems.
Only use the conguration in Figure 6
where the sprinkler tting and water-
lled pipe above the sprinkler tting
are not subject to freezing and where
the length of the Series LFII Sprinkler
has the minimum exposure length per
Figure 8. Refer to the Exposure Length
section and Table B.
For wet-pipe system installations of the
1-inch NPT Series LFII Dry-Type Resi-
dential Sprinklers connected to CPVC
piping, use only the following TYCO
CPVC ttings:
• 1” x 1” NPT Female Adapter (P/N 80145)
• 1” x 1” x 1” NPT Sprinkler Head Adapter
Tee (P/N 80259)
NOTICE
Do not install the Series LFII Dry-Type
Residential Horizontal Sidewall Sprin-
klers into any other type fitting without
first consulting the Technical Services
Department. Failure to use the appro-
priate fitting may result in the following:
• failure of the sprinkler to operate
properly due to formation of ice over
the Inlet Plug or binding of the Inlet
Plug.
• insufcient engagement of the in-
let pipe threads with consequent
leakage.
Drainage
Branch, cross, and feed-main piping
connected to Series LFII Dry-Type Resi-
dential Sprinklers and subject to freezing
temperatures must be pitched to allow
proper drainage, in accordance with the
minimum requirements of the National
Fire Protection Association for dry pipe
sprinkler systems.
Exposure Length
When using Series LFII Dry-Type Resi-
dential Horizontal Sidewall Sprinklers
in wet pipe sprinkler systems to protect
areas subject to freezing temperatures,
use Table B to determine a sprinkler’s
appropriate exposed barrel length to
prevent water from freezing in the con-
necting pipes due to conduction. The
exposed barrel length measurement must
be taken from the face of the sprinkler
tting to the surface of the structure or
insulation that is exposed to the heated
area. Refer to Figure 8 for an example.

Clearance Space
When connecting an area subject to
freezing and an area containing a wet-
pipe sprinkler system, the clearance
space around the sprinkler barrel of
Dry-Type Residential Sprinklers must
be sealed, in accordance with the Na-
tional Fire Protection Association. Due
to temperature differences between the
two areas, the potential for the forma-
tion of condensation in the sprinkler and
subsequent ice build-up is increased. If
this condensation is not controlled, ice
build-up can occur that might damage
the dry-type sprinkler and/or prevent
proper operation in a re situation.
Use of the Model DSB-2 Dry Sprinkler
Boot, described in technical data sheet
TFP591 and shown in Figures 6 through
8, can provide the recommended seal.
Installation
The TYCO Series LFII Dry-Type Resi-
dential Horizontal Sidewall Sprinklers
must be installed in accordance with
the following instructions.
NOTICE
The Series LFII Dry-Type Residential
Horizontal Sidewall Sprinklers must
only be installed in fittings that meet
the requirements of the Design Criteria
section. For other important require-
ments regarding piping design and
sealing of the clearance space around
the Sprinkler Casing, refer to the Design
Criteria section.
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).
Obtain a leak-tight 1-inch NPT sprinkler
joint by applying a minimum-to-maximum
torque of 20 to 30 ft.-lbs. (26,8 to 40,2
Nm). Higher levels of torque can distort the
sprinkler Inlet or Frame 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.
1. Install horizontal sidewall sprinklers
only in the horizontal position with
their centerline of waterway perpen-
dicular to the back wall and parallel
to the ceiling. The word TOP on the
Deector is to face towards the ceiling.
2. With a non-hardening pipe-thread
sealant such as Teon tape applied
to the inlet threads, hand-tighten the
sprinkler into the sprinkler tting.
3. Wrench-tighten the sprinkler into the
sprinkler tting using a pipe wrench
on the Inlet Band or the Casing (Fig-
ure 1).
• For plain-barrel horizontal side-
wall sprinklers, apply the Wrench
Recess End “A” of the W-Type 6
Sprinkler Wrench (Figure 4) to the
Wrench Flat.
• For recessed horizontal sidewall
sprinklers, apply the Wrench Re-
cess of the W-Type 7 Sprinkler
Wrench to the Wrench Flat (Fig-
ure 5).
Note: If sprinkler removal is necessary,
remove the sprinkler using the same
wrenching method noted above.
Sprinkler removal is easier when a
non-hardening sealant was used
and torque guidelines were followed.
After removal, inspect the sprinkler
for damage.
4. After installing the ceiling or apply-
ing a ceiling nish, slide the Style 20
Recessed Escutcheon Closure over
the sprinkler. Push the closure over
the mounting plate until its ange
contacts the wall.
Care and
Maintenance
The TYCO Series LFII Dry-Type Residential
Horizontal Sidewall Sprinklers (TY2335)
must be maintained and serviced in
accordance with the following instruc-
tions. Otherwise, inadvertent sprinkler
operation or non-operation in the event
of a re can result.
NOTICE
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, obtain permission to shut
down the affected fire protection systems
from the proper authorities and notify
all personnel who may be affected by
this action.
Absence of a Recessed Escutcheon
Plate or a Domed Concealed Cover
Plate to cover a clearance hole can delay
sprinkler operation in a re situation.
A Vent Hole is provided in the Bulb Seat
(Figure 1) to indicate if the Series LFII
Dry-Type Residential Horizontal Sidewall
Sprinkler is remaining dry. Evidence of
leakage from the Vent Hole indicates
potential leakage past the Plug with Seal-
ing Assembly and the need to remove
the sprinkler to determine the cause
of leakage (for example, an improper
installation or an ice plug). Close the
re protection system control valve
and drain the system before removing
the sprinkler.
Exercise care to avoid damage to sprin-
klers before, during, and after installation.
Never paint, plate, coat, or otherwise
alter automatic sprinklers after they
leave the factory.
Replace sprinklers that:
•were modied or over-heated.
•were damaged by dropping, striking,
wrench twisting, wrench slippage, or
the like.
•are leaking or exhibiting visible signs
of corrosion.
• were exposed to corrosive products
of combustion but have not operated,
if you cannot easily remove combus-
tion by-products with a cloth.
• have a cracked Bulb or have lost liquid
from the Bulb. Refer to the Installation
section in this data sheet.
Responsibility lies with the owner 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
(for example, NFPA 25), in addition to
the standards of any authorities hav-
ing 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.
