General
Description
The TYCO RAPID RESPONSE Series LFII
Dry-Type Residential Recessed Pendent
Sprinklers are decorative, fast response,
frangible bulb sprinklers designed for
use in residential occupancies such as
homes, apartments, dormitories, and
hotels. 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 Re-
cessed Pendent 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.
The Series LFII Dry-Type Residential
Recessed Pendent 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.
The Series LFII Dry-Type Residential
Recessed Pendent Sprinklers provide
exibility in adjusting sprinklers to the
xed pipe drops. The Recessed Es-
cutcheon 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.
NOTICE
The Series LFII Dry-Type Residential
Recessed Pendent Sprinklers (TY2235)
described herein must be installed and
maintained in compliance with this docu-
ment, as well as with the applica ble
standards of the National Fire Protection
Association, in addition to the standards
of any authorities hav ing jurisdiction.
Failure to do so may impair the perfor-
mance of these de vices.
Owners are responsible for maintain ing
their fire protection system and de vices in
proper operating condition. The install-
ing contractor or sprinkler manufacturer
should be contacted with any questions.

Operation
When the TYCO Series LFII Dry-Type
Residential 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 Recessed Pendent Sprinklers
(TY2235) 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.
Examples of sprinkler designs follow:
• Example 1 — Protection is planned for
a corridor that is 8 feet wide. Conse-
quently, the actual coverage area un-
der consideration is 8 ft. x 20 ft. Using
the Series LFII Dry-Type Residential
Sprinkler, the ow rate listed in Table
A for a 20 ft. x 20 ft. coverage area is
21 GPM. However, based on a mini-
mum discharge of 0.1 GPM/sq. ft., the
expected ow rate is 16 GPM (8 ft. x
20 ft = 160 sq.ft.). For this example, a
minimum ow rate of 21 GPM for this
sprinkler design is required.
• Example 2 — Protection is planned
for a long, narrow room that is 12 feet
wide. Consequently, the actual cover-
age area under consideration is 12 ft.
x 20 ft. Using the Series LFII Dry-Type
Residential Sprinkler, the ow rate listed
in Table A for a 20 ft. x 20 ft. coverage
area is 21 GPM. However, based on
a minimum discharge of 0.1 GPM/sq.
ft., the expected ow rate is 24 GPM
(12 ft. x 20 ft = 240 sq.ft.). For this ex-
ample, a minimum ow rate of 24 GPM
for this sprinkler design is required.
Obstruction to Water
Distribution
Sprinklers are to be located in accordance
with the obstruction rules of NFPA 13D,
13R, and 13 as applicable for residential
sprinklers as well as with the obstruc-
tion criteria described within the TYCO
technical data sheet TFP490.
Operational Sensitivity
The sprinkler must be located relative
to the mounting surface as shown in
Figure 3.
Sprinkler Spacing
The minimum spacing between sprinklers
is 8 feet (2,4 m). The maximum 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 20 feet for a
20 ft. x 20 ft. coverage area.
Sprinkler Fittings
Install the 1-inch NPT Series LFII Dry-
Type Residential Recessed Pendent
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 systems, only use the side
outlet of maximum 2-1/2 inch size reduc-
ing tees when locating the Series LFII
Dry-Type Residential Recessed Pendent
Sprinklers 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 Series LFII Dry-Type
Residential Recessed Pendent Sprin-
klers into elbow ttings. The Inlet of
the sprinkler can contact the interior
of the elbow, potentially damaging the
Inlet seal.
Typically, the end sprinkler tting on
a branch line is plugged as shown in
Figure 6.
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 4
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 6. Refer to the Exposure Length
section and Table B.
For wet pipe system installations of
the 1-inch NPT Series LFII Dry-Type
Residential Recessed Pendent Sprinklers
connected to CPVC piping, use only the
following TYCO CPVC ttings:
• 1” x 1” x 1” NPT Sprinkler Head Adapter
Tee (P/N 80249)
• 1” x 1” NPT Female Adapter (P/N 80145)
For residential dry pipe systems subject
to freezing, use the of 1” x 1” x 1” NPT
CPVC Sprinkler Head Adapter Tee (P/N
80259).

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 Recessed Pendent Sprinklers
must be sealed, in accordance with the
National Fire Protection Association. Due
to temperature differences between two
areas, the potential for the formation
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 4 through
6, can provide the recommended seal.
Installation
The TYCO Series LFII Dry-Type Resi-
dential Recessed Pendent Sprinklers
must be installed in accordance with
the following instructions.
NOTICE
The Series LFII Dry-Type Residential
Recessed Pendent Sprinklers must
only be installed in fittings that meet
the requirements of the Design Criteria
section. For other important require-
ments regard ing 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
NOTICE
Do not install the Series LFII Dry-Type
Residential Recessed Pendent Sprinklers
into any other type fitting without first
consulting the Technical Services De-
partment. Failure to use the appropriate
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 in-
let pipe threads with consequent
leakage.
Drainage
Branch, cross, and feed-main piping con-
nected to Series LFII Dry-Type Residential
Recessed Pendent 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 Recessed Pendent 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 6 for an example.

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 or Cover-Retainer Assembly by
under- or over-tightening the Sprinkler.
Re-adjust the position of the sprinkler
tting to suit.
1. Install pendent sprinklers only in the
pendent position with the deector
parallel to 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 using
a pipe wrench on the Inlet Band or
the Casing (refer to Figure 1) or us-
ing the W-Type 7 Sprinkler Wrench
on the Wrench Flat (refer to Figure
3). Apply the Wrench Recess of the
W-Type 7 Sprinkler Wrench to the
Wrench Flat.
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.

Care and
Maintenance
The TYCO Series LFII Dry-Type Residential
Recessed Pendent Sprinklers (TY2235)
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 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 Sprinkler is remain-
ing dry. Evi dence of leakage from the
Vent Hole indicates potential leakage
past the Plug with Sealing 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 sys-
tem 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 combustion
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
in spection, 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 Protec tion 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 in accordance with local require-
ments and/or national codes.
