Series LFII Residential Sprinkler
4.4 K-factor Horizontal Sidewall, Dry Type
Wet Pipe System
The Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers are typ-
ically used where sprinklers and/or a
portion of the connecting piping are
exposed to freezing temperatures (for
example, horizontal sprinkler supplied
from wet systems into unheated areas).
The Series LFII Dry Type Residen-
tial Horizontal Sidewall Sprinklers are
intended for use in Residential Sprin-
kler systems for one- and two-family
dwellings and mobile homes per NFPA
13D; residential sprinkler systems for
residential occupancies up to and
including four stories in height per
NFPA 13R; or, sprinkler systems for the
residential portions of any occupancy
per NFPA 13.
The recessed version 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
design of this escutcheon provides a
level of flexibility in adjusting sprinkler
supply connections.
The Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers have
been designed with heat sensitivity and
water characteristics proven to help in
the control of residential fires and to
improve the chance for occupants to
escape or be evacuated.
Corrosion-resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion-resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable Approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these coatings for any given
corrosive environment. The effects of

Description
The TYCO Series LFII Dry Type Res-
idential Horizontal Sidewall (HSW)
Sprinklers (TY2335) are dry-type dec-
orative, fast response, frangible bulb
sprinklers designed for use in residen-
tial occupancies such as homes, apart-
ments, dormitories, and hotels.
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.
NOTICE
The Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers (TY2335)
described herein must be installed and
maintained in compliance with this doc-
ument and the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION (NFPA), in addition to
the standards of any authorities having
jurisdiction. Failure to do so may impair
the performance of these devices.

Operation
When the TYCO Series LFII Dry Type
Residential Horizontal Sidewall Sprin-
kler is in service, water is prevented
from entering the assembly by the Plug
with Sealing Assembly (see Figure 1) in
the Inlet of the Sprinkler.
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 to release the Bulb Seat. The
system’s water pressure is then able to
unseat the Plug with Sealing Assem-
bly. The Plug Spring turns the Plug with
Sealing Assembly aside, allowing the
sprinkler to activate and flow water.
Design
Criteria
The TYCO Series LFII Dry Type Resi-
dential Horizontal Sidewall Sprinklers
(TY2335) 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 criteria provided in
this section, refer to the technical data
sheet entitled Residential Sprinkler
Design Guide (TFP490) for the manu-
facturer’s recommendations that may
be acceptable to the local authority
having jurisdiction.
System Type
Wet Pipe
Hydraulic Design
(NFPA 13D and 13R)
For systems designed to NFPA 13D or
NFPA 13R, the minimum required sprin-
kler flow rates 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 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 as a
function of temperature rating and
the maximum allowable coverage
area.
• minimum discharge of 0.1 gpm/ft²
over the design area comprised
of the four most hydraulically
demanding 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 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 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 ft (2,4 m). The maximum
lateral spacing between sprinklers
cannot exceed the length of the cov-
erage area (see Table A) hydraulically
calculated (for example, a maximum of
12 ft for a 12 ft x 12 ft coverage area or
18 ft for a 18 ft x 20 ft coverage area.)

f. For sprinklers installed prior to May 1, 2015, a ow rate of 15 gpm at a pressure of 11.6 psi may be used.
g. For sprinklers installed prior to May 1, 2015, a ow rate of 19 gpm at a pressure of 18.6 psi may be used.
h. For sprinklers installed prior to May 1, 2015, a ow rate of 20 gpm at a pressure of 20.7 psi may be used.
j . For sprinklers installed prior to May 1, 2015, a ow rate of 25 gpm at a pressure of 32.3 psi may be used.
NOTICE
Do not install the Series LFII Dry Type
Residential Horizontal Sidewall Sprin-
klers into any other type fitting without
first consulting Johnson Controls Tech-
nical Services. 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.
• insufficient engagement of the
inlet pipe threads with consequent
leakage.
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 the appro-
priate exposed sprinkler barrel length
to prevent water from freezing in the
connecting pipes due to conduction.
The exposed barrel length measure-
ment must be taken from the face of
the sprinkler fitting to the surface of the
structure or insulation that is exposed
to the heated area. See Figure 5 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
NATIONAL FIRE PROTECTION ASSO-
CIATION. Due to temperature differ-
ences between the two areas, the
potential for the formation of conden-
sation in the sprinkler and subsequent
ice build-up is increased. If this con-
densation 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 Sprin-
kler Boot, described in Technical Data
Sheet TFP591 and shown in Figures 4
and 5, can provide the recommended
seal.

Installation
TYCO Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers must
be installed in accordance with this
section.
General Instructions
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, see 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 sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in.
(1,6 mm).
A leak-tight 1 in. NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque of 20 to 30
lb-ft (26,8 to 40,2 N∙m). 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
insufficient adjustment in an Escutch-
eon Plate by under- or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Note: Install horizontal sidewall sprin-
klers only in the horizontal position
with their centerline of waterway par-
allel to the ceiling. The word TOP on the
Deflector is to face towards the ceiling.
Step 1. With a non-hardening pipe-
thread sealant such as Teflon tape
applied to the inlet threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 2. Wrench-tighten the sprinkler
using a pipe wrench on the Inlet Band
or the Casing (see Figure 1), or using
the W-Type 6 or W-Type 7 Sprinkler
Wrench as follows:
• For plain-barrel horizontal sidewall
sprinklers, apply the Wrench
Recess End “A” of the W-Type 6
Sprinkler Wrench (see Figure 6) to
the Wrench Flat.
• For recessed horizontal sidewall
sprinklers, apply the Wrench
Recess of the W-Type 7 Sprinkler
Wrench to the Wrench Flat
(see Figure 7).
Absence of a Recessed Escutch-
eon Plate or a Domed Concealed
Cover Plate to cover a clearance hole
can delay 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.
A Vent Hole is provided in the Bulb
Seat (see Figure 1) to indicate if the
Series LFII Dry Type Residential Hor-
izontal Sidewall Sprinkler is remain-
ing dry. Evidence of leakage from the
Vent Hole indicates potential leakage
past the Plug with Sealing Assembly
and the need to remove the sprinkler

kler removal is easier when a non-hard-
ening sealant was used and torque
guidelines were followed. After removal,
inspect the sprinkler for damage.
Step 3. After installation of the gypsum
board or other wall/soffit finish material,
slide the Style 20 Recessed Escutch-
eon Closure over the sprinkler. Push
the closure over the mounting plate
until its flange contacts the wall.
