General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent
Sprinklers (TY2284) are decorative,
fast response, fusible solder sprinklers
designed for use in residential occu-
pancies such as homes, apart-
ments, dormitories, and hotels. When
aesthetics is the major consideration,
the Series LFII Residential Sprinklers
(TY2284) 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 ush design of the Series LFII
Residential 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
sensitivity and water distribution
characteristics proven to help in the
control of residential res 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 specied for wet pipe sprinkler
systems, as is customary for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series LFII
Residential Sprinklers (TY2284) 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 Flush
Pendent Sprinklers (TY2284) 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 jurisdiction. 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 condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.

Operation
The sprinkler assembly contains a small
fusible solder element. When exposed
to sufcient heat from a re, the solder
melts and enables the internal compo-
nents of the sprinkler to fall away. At
this point the sprinkler activates with
the deector dropping into its operated
position (Figure 1C), permitting water
to ow.
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 at 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 ow rate are given in Tables
A and B 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
and B as a function of temperature
rating and the maximum allowable
coverage area.
•A minimum discharge of 0.1
gpm/ft2over the “design area”
comprised of the four most hydrau-
lically demanding sprinklers for
the actual coverage areas being
protected by the four sprinklers.
The number of “design sprinklers”
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
Pendent Sprinklers (TY2284) 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 Technical Data Sheet TFP490.
Operational Sensitivity
The sprinklers are to be installed in
the ush position per Figure 1 with the
provided escutcheon.
Sprinkler Spacing
The minimum spacing between sprin-
klers is 8 feet (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 feet 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 ux, 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 re 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 re sprinkler system,
the copper piping must be installed
in conformance 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
sprinkler system, either internally or
externally, must be done with use of
only an ASTM B 813 approved ux.
Residual ux must be thoroughly
removed from both the interior and
exterior surfaces of the piping before
installing the sprinkler heads. The use
of improper ux, or the failure to thor-
oughly remove proper ux, may result
in corrosion of the sprinkler heads or
stress corrosion 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
Sprinklers (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 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 the sprinkler
by under- or over-tightening the
Sprinkler/Support Cup Assembly. Re-
adjust the position of the sprinkler
tting to suit.
Each sprinkler must be inspected
before installation. Do not use any
sprinkler that exhibits any deformations
or cracks, including cracks on the
protective cap.
Step 1. The sprinkler must be installed
only in the pendent position and with
the sprinkler waterway centerline
perpendicular 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 inches (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 tolerance
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
completed with the 2 inch (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,
relocate the sprinkler fitting as
necessary.
Care and
Maintenance
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent
Sprinklers (TY2284) must be main-
tained 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 or overheated sprinklers must
be replaced.
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.
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
recommended to be inspected,
tested, and maintained by a qualied
Inspection Service in accordance with
local requirements and/or national
codes.
