General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Pendent Sprinklers
(TY1234) are decorative, fast response,
frangible bulb sprinklers designed for
use in residential occupancies such as
homes, apartments, dormitories, and
hotels. When aesthetics and optimized
flow characteristics are key consider-
ations, the Series LFII (TY1234) should
be the first choice.
The 3.0 K-factor of the Series LFII Res-
idential Pendent Sprinkler has been
designed to optimize flows (that is, to
avoid over discharging) specifically
for small coverage areas up to 14 ft x
14 ft (4,3 m x 4,3 m). The required resi-
dential flow rates can then be delivered
with the use of smaller pipe sizes and
reduced water supply requirements.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet pipe residential sprinkler
systems for one-and two-family
dwellings and mobile homes per
NFPA 13D
• wet pipe residential sprinkler
systems for residential occupan-
cies up to and including four stories
in height per NFPA 13R
• wet pipe sprinkler systems for
the residential portions of any
occupancy per NFPA 13
The recessed version of the Series
LFII Residential Pendent Sprinkler is
intended for use in areas with finished
ceilings. It employs a two-piece Style
20 Recessed Escutcheon.
The Recessed Escutcheon provides
1/4 in. (6,4 mm) of recessed adjust-
ment or up to 1/2 in. (12,7 mm) of total
adjustment from the flush ceiling posi-
tion. The adjustment provided by the
Recessed Escutcheon reduces the
accuracy to which the pipe drops to
the sprinklers must be cut.
The Series LFII Residential Pendent
Sprinkler has been designed with heat
sensitivity and water distribution char-
acteristics 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
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 Residential Pendent
Sprinklers (TY1234) described herein
must be installed and maintained in
compliance with this document and
with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION (NFPA), in addition to the
standards of any authorities having
jurisdiction. Failure to do so may impair
the performance of these devices.

expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and flow water.

Installation
The TYCO RAPID RESPONSE Series
LFII Residential Pendent Sprinklers
(TY1234) must be installed in accor-
dance with this section:
General Instructions
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 1/2 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 an Escutch-
eon Plate by under-or over-tightening
the Sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Residential Sprinkler Design Guide
When conditions exist that are outside
the scope of the provided criteria, refer
to the Residential Pendent Sprinkler
Design Guide TFP490 for the manufac-
turer’s recommendations that may be
acceptable to the local authority having
jurisdiction.
System Type
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)
The minimum required sprinkler
flow rate for systems designed to
NFPA 13D or NFPA 13R are given in
Table A 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.
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 ow rates given in Table A for
NFPA 13D and 13R as a function of
TFP402 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
actual coverage areas protected by
the 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 applica-
ble for residential sprinklers as well as
with the obstruction criteria described
within the TYCO technical data sheet
TFP490.
Operational Sensitivity
Sprinklers are to be installed with
a deflector-to-ceiling distance of
1-1/4 in. to 4 in.
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 being hydraulically calculated
(for example a maximum of 12 ft for a
12 ft x 12 ft coverage area, or 16 ft for a
16 ft x 16 ft coverage area.) See Table
A.
Max.

Care and
Maintenance
The TYCO RAPID RESPONSE Series
LFII Residential Pendent Sprinklers
(TY1234) must be maintained and ser-
viced 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
system from the proper authorities
and notify all personnel who may be
affected by this decision.
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 other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
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. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. See the Installation
section for additional information.
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, for example, NFPA 25,
in addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or sprinkler
manufacturer regarding any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
