General
Description
Johnson Controls Residential Sprin-
klers are a type of fast-response auto-
matic sprinklers. They are to be used
only in wet or dry pipe residential sprin-
kler systems for one-and two-family
dwellings and mobile homes per NFPA
13D; wet or dry pipe residential sprin-
kler systems for residential occupan-
cies up to and including four stories
in height per NFPA 13R; or, wet or dry
pipe sprinkler systems for the resi-
dential portions of any occupancy per
NFPA 13.
This document provides design guid-
ance for the Series LFII Residential
Sprinklers outlined in Table A.
Residential fire sprinkler systems
should only be designed and installed
by those competent and completely
familiar with automatic sprinkler system
design, installation procedures, and
techniques. Several criteria may apply

Background
All Series LFII Residential Sprinklers are
tested and listed under UL 1626 “Stan-
dard for Residential Sprinklers for Fire
Protection Service” with specic pub-
lished spacings, ows, and pressures
for each residential sprinkler identied
by its Sprinkler Identication Number
(SIN) and as detailed in the Technical
Data Sheets referenced in Table A.
The design criteria for Series LFII res-
idential sprinklers contained in the
current NFPA Standards must be fol-
lowed except as modied by the indi-
vidual UL 1626 listing information
provided in the Technical Data Sheets
referenced in Table A and this design
guide.
NOTICE
The approval of all residential sprin-
kler designs and installations must be
made by the authority having jurisdic-
tion for compliance with all governmen-
tal codes and standards.
Design:
Hydraulics
NFPA 13D. The number of design
sprinklers shall include all sprin-
klers within a compartment up to a
maximum of two sprinklers where spe-
cic UL Listed ows are provided. The
minimum required sprinkler ow rate
for systems designed to NFPA 13D
are given in the Technical Data Sheets
referenced in Table A, as a function of
temperature rating and the maximum
allowable coverage areas.
Note: For actual coverage areas less
than or between those indicated in
the Technical Data Sheets referenced
in Table A, it is necessary to use the
minimum required flow for the next
largest coverage area.
Example No. 1: Assuming the use of a
pendent sprinkler, the actual coverage
area being protected is 14 ft x 16 ft.
In this case the minimum ow require-
ment for a 16 ft x 16 ft coverage area
must be used.
Example No. 2: Assuming the use of a
pendent sprinkler, the actual coverage
area being protected is 17 ft x 17 ft.
In this case the minimum ow require-
ment for a 18 ft x 18 ft coverage area
must be used.
NFPA 13R. The number of design
sprinklers shall include all sprin-
klers within a compartment up to a
maximum of four sprinklers where spe-
cic UL Listed ows are provided. The
minimum required sprinkler ow rate
for systems designed to NFPA 13R
are given in the Technical Data Sheets
referenced in Table A, as a function of
temperature rating and the maximum
allowable coverage areas.
Note: For actual coverage areas less
than or between those indicated in
the Technical Data Sheets referenced
in Table A, it is necessary to use the
minimum required flow for the next
largest coverage area.
Example 1: Assuming the use of a
pendent sprinkler, the actual coverage
area being protected is 14 ft x 16 ft.
In this case the minimum ow require-
ment for a 16 ft x 16 ft coverage area
must be used.
Example 2: Assuming the use of a
pendent sprinkler, the actual coverage
area being protected is 17 ft x 17 ft.
In this case the minimum ow require-
ment for a 18 ft x 18 ft coverage area
must be used.
NFPA 13. The number of design sprin-
klers 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 the Technical
Data Sheets referenced in Table A for
NFPA 13D and 13R as a function of
temperature rating and the maximum
allowable coverage area.
Note: For actual coverage areas less
than or between those indicated in
the Technical Data Sheets referenced
in Table A, it is necessary to use the
minimum required flow for the next
largest coverage 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 cover-
age areas being protected by the
four sprinklers.
Note: The greatest dimension of the
actual coverage area cannot be any
greater than the maximum coverage
areas indicated in the Technical Data
Sheets referenced in Table A.

Example 1: A corridor being protected
is 8 ft wide; consequently, an actual
coverage area of 8 ft x 20 ft is being
contemplated. Based on using the LFII
(TY2236) Residential Pendent Sprinkler,
the ow rate provided in TFP403 for a
20 ft x 20 ft coverage area is 20 gpm.
However based on minimum discharge
of 0.1 gpm/ft² the ow rate would be 16
gpm. In this case a minimum ow rate
of 20 gpm for this design sprinkler must
be utilized.
Example 2: A long narrow room being
protected is 12 ft wide; consequently,
an actual coverage area of 12 ft x 20
ft is being contemplated. Based on
using the LFII (TY2236) Residential
Pendent Sprinkler, the ow rate pro-
vided in TFP403 for a 20 ft x 20 ft cov-
erage area is 20 gpm. However based
on minimum discharge of 0.1 gpm/ft²
the ow rate would be 24 gpm. In this
case a minimum ow rate of 24 gpm for
this design sprinkler must be utilized.
Compartment. A compartment is a
space that is completely enclosed by
walls and a ceiling. The compartment
enclosure may have openings to an
adjoining space, provided the open-
ings have a minimum lintel depth of 8
inches from the ceiling.
Sloped Ceilings. For systems
designed to NFPA 13, 13D, or 13R and
where specic UL Listed ows have
not been provided for sloped ceilings,
consult with the local authority having
jurisdiction with regard to the number
of “design sprinklers” for sloped ceil-
ings having a slope greater than a 2 in.
rise for a 12 in. run.
Design:
Sprinkler
Location
When locating the Series LFII Resi-
dential Sprinklers, Sprinkler Spacing,
Obstruction To Water Distribution, Heat
Sensitivity, Preventing Cold Soldering,
and Proximity To A Heat Source must
all be considered.
Table B provides a conversion of
“Rise Over Run” that is a conventional
method of dening slope in architec-
tural drawings to “Degrees Of Slope”
as used in this guideline.
Sprinkler Spacing Under Horizontal
Ceilings (Up to 9 degrees of slope).
Residential sprinklers are utilized for
various maximum spacings in accor-
dance with minimum ows and pres-
sures. Typical coverage areas for
pendent sprinklers are 12 ft x 12 ft up to
20 ft x 20 ft, and typical coverage areas
for horizontal sidewall sprinklers are
12 ft x 12 ft up to 16 ft x 20 ft. Refer to
the Technical Data Sheets referenced
in Table A for coverage areas, and refer
to the applicable NFPA standard for
Spacing Rules Under Horizontal Ceil-
ings. Understanding the intended area
of coverage while using this guide is
critical.
Always remember that the spacing of
sprinklers under horizontal ceilings
with slopes greater than 0 degrees
(i.e., non-level) is measured along the
slope when determining distance off of
walls and between sprinklers.
Sprinkler Spacing Under Sloped
Ceilings (10 to a 60 degrees of
slope).
Residential sprinklers are utilized for
various maximum spacings in accor-
dance with minimum ows and pres-
sures. Typical coverage areas for
pendent sprinklers are 12 ft x 12 ft up
to 20 ft x 20 ft, and typical coverage
areas for horizontal sidewall sprinklers
are 12 ft x 12 ft up to 16 ft x 20 ft. Refer
to the Technical Data Sheets refer-
enced in Table A for coverage areas,
and see Figure 1 for Spacing Rules
Under Sloped Ceilings. Understanding
the intended area of coverage while
using this guide is critical.
Always remember that the spacing of
sprinklers under sloped ceilings is mea-
sured along the slope when determin-
ing distance off of walls and between
sprinklers.
Obstruction to Water Distribution.
Location with respect to obstructions
to water distribution are addressed
by the applicable NFPA standard. For
other obstruction scenarios which are
not addressed by NFPA, see the appro-
priate gures within this data sheet. If
a sprinkler water distribution pattern
is obstructed, the obstruction is to be
considered the maximum distance of
coverage for a given sprinkler and addi-
tional sprinklers beyond the obstruction
will be necessary. Because of the varied
nature of residential type construc-
tion, there will be some compartment
designs that cannot be fully sprinklered
in accordance with the recommenda-
tions of NFPA 13, 13D, or 13R. In the
event of this condition, consult with the
authority having jurisdiction.
Appendix material in NFPA 13D and
13R references the evaluation of certain
small areas.
Small areas created by architectural
features such as planter box windows,
bay windows, and similar features can
be evaluated as follows:
(a) Where no additional oor space area
is created by the architectural feature,
no additional sprinkler protection is
required.
(b) Where additional floor space is
created by an architectural feature,
no additional sprinkler protection is
required, provided all of the following
conditions are met:
• The oor area does not exceed 18
square feet.
• The oor area is not greater than 2
feet in depth at the deepest point of
the architectural feature to the plane
of the primary wall where measured
along the nished oor.
• The oor is not greater than 9 feet
in length where measured along the
plane of the primary wall.

Measurement from the deepest point of
the architectural feature to the sprinkler
should not exceed the maximum listed
spacing of the sprinkler. The hydrau-
lic design is not required to consider
the area created by the architectural
feature.
Figure 2 provides guidance for position-
ing of pendent and horizontal sidewall
sprinklers with respect to obstructions
along a wall, and in the case of pendent
sprinklers the positioning of sprinklers
on both sides of a continuous obstruc-
tion located at the ceiling. Consider-
ation must be given to the size of the
obstruction, as well as the allowable
deector-to ceiling distance.
Heat Sensitivity. Sensitivity to heat is
critical for prompt operation of a resi-
dential sprinkler for a re condition. The
Technical Data Sheets referenced in
Table A provide the allowable sprinkler
deector-to-ceiling distances.
Residential sprinklers are to be installed
beneath smooth at ceilings as dened
by NFPA 13.
NOTICE
Special consideration, such as increas-
ing the number of design sprinklers
being hydraulically calculated, must be
given to installations where continuous
obstructions to heat ow are present
(e.g.: beams, lintels, etc.).
Under a sloped ceiling, the residential
sprinkler(s) located at the highest ele-
vation must not be located more than
3 feet measured vertically down from
the peak.
Preventing Cold Solder. A minimum
distance between residential sprin-
klers to prevent cold soldering, such
as the wetting from an operated sprin-
kler onto an unoperated sprinkler that
could prevent its potential to operate if
needed, must be maintained.
Under horizontal ceilings, the minimum
distance between residential sprinklers
to prevent cold soldering is 8 feet.
Sloped ceilings, however, present more
of a cause for concern for cold solder-
ing, since the elevation of one sprinkler
may be higher than another, resulting in
a different distribution pattern than that
of a horizontal ceiling condition.
Figure 1 - Spacing Rules Under Sloped
Ceilings addresses the minimum
acceptable distance under various
sloped ceiling conditions that will take
into account the prevention of cold
soldering.
One solution to prevent cold solder-
ing is to stagger the sprinklers so that
the distance between two sprinklers
is increased. In some case, bafes
can be located midway between two
closely located sprinklers to prevent
cold soldering.
Proximity To A Heat Source. Sprin-
klers must be located so as to prevent
an inadvertent operation due to expo-
sure of normal heat sources. Loca-
tion with respect to exposure of heat
sources other than re that may cause
an inadvertent operation of a residential
sprinkler. Refer to the applicable NFPA
standard.
Installation
The Series LFII Residential Sprinklers
must be installed in accordance with
the applicable Technical Data Sheet
referenced in Table A.
Care and
Maintenance
The Series LFII Residential Sprinklers
must be maintained and serviced in
accordance with the applicable Tech-
nical Data Sheet referenced in Table A.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
