General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) are decorative, fast
response, fusible solder sprinklers
designed for use in residential occu-
pancies such as homes, apartments,
dormitories, and hotels. When aes-
thetics is the major consideration,
the Series LFII Residential Sprinklers
(TY2284) should be the first 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 flush design of the Series LFII Resi-
dential Sprinklers features a separable
escutcheon providing 3/8 inch (9,5 mm)
vertical adjustment. This adjustment
reduces the accuracy to which the pipe
drops to the sprinklers must be cut.
The Series LFII Residential Sprinklers
have been designed with heat sensi-
tivity and water distribution charac-
teristics proven to help in the control
of residential fires and to improve the
chance for occupants to escape or be
evacuated.
Dry Pipe System Application
The Series LFII Residential Flush
Pendent Sprinklers offers a laboratory
approved option for designing dry pipe
residential sprinkler systems, whereas,
most residential sprinklers are labora-
tory approved for wet systems only.
Through extensive testing, it has been
determined that the number of design
sprinklers (hydraulic design area)
for the Series LFII Residential Flush
Pendent Sprinklers (TY2284) need
not be increased over the number of
design sprinklers (hydraulic design
area) as specified for wet pipe sprinkler
systems, as is customary for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series LFII Residen-
tial Sprinklers (TY2284) offer the fea-
tures of non-water filled 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.
NOTICE
The Series LFII Residential Flush
Pendent Sprinklers (TY2284) described
herein must be installed and main-
tained in compliance with this docu-
ment and 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 sprinkler assembly contains a
small fusible solder element. When
exposed to sufficient heat from a fire,
the solder melts and enables the inter-
nal components of the sprinkler to fall
away. At this point the sprinkler acti-
vates with the deflector dropping into
its operated position (Figure 1C), per-
mitting water to flow.
Design
Criteria
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent
Sprinklers (TY2284) 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 manufacturer’s
recommendations that may be accept-
able to any local authority having
jurisdiction.
System Types
Per the UL Listing, wet pipe and dry
pipe systems may be utilized. Per the
C-UL Listing, only wet pipe systems
may be utilized.
Ceiling Types
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
sprinkler flow rate are given in Tables
A and B as a function of temperature
rating and the maximum allowable cov-
erage 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. The number of “design
sprinklers” specified 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 dis-
charge from each of the four sprinklers
is to be the greater of the following:
• The flow rates given in Tables A and
B as a function of temperature rating
and the maximum allowable cover-
age area.
• A minimum discharge of 0.1 gpm/ft2
over the “design area” comprised of
the four most hydraulically demand-
ing sprinklers for the actual coverage
areas being protected by the four
sprinklers.
The number of design sprinklers speci-
fied 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 Residen-
tial Pendent Sprinklers (TY2284) in
dry pipe sprinkler systems, the time
for water delivery must not exceed 15
seconds for the most remote operat-
ing 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 Technical Data Sheet TFP490.
Operational Sensitivity
The sprinklers are to be installed in the
flush position per Figure 1 with the pro-
vided escutcheon.
Sprinkler Spacing
The minimum spacing between sprin-
klers is 8 ft (2,4 m). The maximum
spacing between sprinklers cannot
exceed the length of the coverage
area (Table A or B) being hydraulically
calculated (e.g., maximum 12 ft for a
12 ft x 12 ft coverage area, or 20 feet for
a 20 ft x 20 ft coverage area).
Precautionary Warnings for
Corrosive Environments
The Series LFII Residential Flush
Sprinkler (TY2284) must be installed
in a non-corrosive environment. The
improper use of corrosive agents such
as flux, or other products that contain
chloride ions, whether applied internally
or externally to the sprinkler system,
may result in corrosion of the sprinkler
heads, or stress corrosion cracking,
which in turn may cause the sprinkler
heads to develop leaks, operate unex-
pectedly or improperly.
Accordingly, it is essential that the
Series LFII Residential Flush Sprinkler
(TY2284) be installed only by expe-
rienced fire sprinkler engineers, who
comply fully with NFPA 13, 13D, 13R
and 25, ASTM B 813, ASTM B 828
and Copper Development Association
(CDA).
Copper Sprinkler System Piping
Any time copper piping is used in any
part of a fire sprinkler system, the
copper piping must be installed in con-
formance with all applicable standards
and requirements for copper piping,
including: NFPA 13, 13D, 13R and 25,
ASTM B 813, ASTM B 828, and Copper
Development Association (CDA).
Any soldering in any part of a sprin-
kler system, either internally or exter-
nally, must be done with use of only an
ASTM B 813 approved flux. Residual
flux must be thoroughly removed from
both the interior and exterior surfaces
of the piping before installing the sprin-
kler heads. The use of improper flux,
or the failure to thoroughly remove
proper flux, may result in corrosion of
the sprinkler heads or stress corro-
sion cracking, which in turn may cause
the sprinkler heads to develop leaks,
operate unexpectedly or improperly.

Installation
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) must be installed in
accordance with this section.
General Instructions
The Protective Cap is to remain on the
sprinkler during installation until the
ceiling installation is complete. The
Protective Cap must be removed to
place the sprinkler in service.
A leak-tight 1/2 in. NPT sprinkler joint
should be obtained by applying a min-
imum-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/Support Cup Assembly. Re- adjust
the position of the sprinkler fitting to
suit.
Each sprinkler must be inspected
before installation. Do not use any
sprinkler that exhibits any deformations
or cracks, including cracks on the pro-
tective cap.
Step 1. The sprinkler must be installed
only in the pendent position and with
the sprinkler waterway centerline per-
pendicular to the mounting surface.
Step 2. Install the sprinkler tting so
that the distance from the face of the
tting to the mounting surface will be
nominally 29/32 in. (23,0 mm) as shown
in Figure 1A.
Step 3. With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 4. Tighten the sprinkler using
only the Sprinkler Socket or Wrench
& Socket Combination (Figure 2). The
wrench recess of the socket is to be
applied to the sprinkler wrenching area
(Figure 1A).
Step 5. Use the “ceiling level toler-
ance limit” indicator on the Protective
Cap to check for proper installation
height. Relocate the sprinkler tting as
necessary. If desired, the Protective
Cap may also be used to locate the
center of the clearance hole by gently
pushing the ceiling material against the
center point of the Cap.
Step 6. After the ceiling has been com-
pleted with the 2 in. (50 mm diameter
clearance hole, use the Protective Cap
Removal Tool (Figure 3) to remove
the Protective Cap and then push on
the Escutcheon until its ange just
comes in contact with the ceiling. Do
not continue to push the Escutcheon
such that it lifts a ceiling panel out of
its normal position. If the Escutcheon
cannot be engaged with the sprinkler,
or the Escutcheon cannot be engaged
sufciently to contact the ceiling, relo-
cate the sprinkler fitting as necessary.
Care and
Maintenance
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) 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
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 the outer piece of an
escutcheon, which is used 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.
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-
fied or overheated sprinklers must be
replaced.
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.
The owner is responsible for the
inspection, testing, and maintenance of
their fire 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 addi-
tion to the standards of any authorities
having jurisdiction. Contact the install-
ing contractor or product manufacturer
regarding any questions.
Automatic sprinkler systems are
recommended to be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
