LFPrM Antilreeze
Agency Listed Solution for
Fire Sprinkler Systems
General
Description
LFPiM antifreeze is a pre-mixed freeze
protection solution designed and listed
for use in wet fire sprinkler systems.
The solution is designed Ior systems
subject to freezing temperatures that
can cause damage to equipment or
impede the proper function of the
system. The solution has been devel-
oped to meet the requirements of
UL 2901 for compliance to the 2019
editions of NFPA 13, 13R, 13D, and the
2017 edilion of NFPA 25.
LFPrM antitreeze remains in a liquid
state at temperatures as low as
-10"F C23,3'C). Upon operation of the
sprinklers during a tlre event, the solu-
tion immediately discharges from lhe
sprinklers and is followed by water rrom
the water supply. Use ot the solution in
sprinkler systems eliminates the deliv-
ery delay times associated with dry
pipe systems.

Design
Criteria
LFPIM antifreeze is a solution spe-
cifically tested and listed by UL for
use within the strict parameters and
requirements in this Technical Data
Sheet.
All fire protection systems shall
contorm to state, local, and NFPA
requirements if employing the use of
LFPrM antirreeze.
Layout and Design
Flow rates, pipe sizing, sprinkler
spacing, hanging methods, and system
design must be in accordance with
NFPA 13. 13R, and 13D. Fire sprin-
kler systems utilizing LFPr antifreeze
shall meet the system size limitations
as tollows:
NFPA 13D
No limitations on sprinkler syslem
volume. Antifreeze shall only be used
in above-ground piping,
NFPA 13R - Occupancies with
Dwelling Units Only
No limitations on sprinkler system
volume in buildings only containing
dwellings. Antifreeze shail only be used
in above-ground piping.
NFPA l3R - Mixed Use Occupancies
Where buildings contain mixed use
occupancies that are ted by a single
sprinkler system, the system size shall
be limited to 40 gal 051 L). Where a
sprinkler system feeds solely dwelling
units, the system size has no limita-
tions. Antifreeze shall only be used in
above-ground piping. Where a system
feeds non-dwelling units, it shall be
limited to 40 gal (151 L). ll future build-
ing renovations result in occupancy
classification changes, a fire sprin-
kler system evaluation must be per-
formed to determine if any changes
are required Ior the use of antifreeze.
NFPA 13
Buildings with occupancy classifi-
cations of Light Hazard and Ordi-
nary Hazard Group 1 and 2 are
limited to a sprinkler system volume
oI 40 gal (151 L). Storage applica-
tions using non-ESFR sprinklers are
limited to a sprinkler system volume of
40 gal (151 L).
@
LFPIM antifreeze is not listed lor use in
prctecting extra hazard occupancies,
tlammable liquids, ot use w,th ESFR
sprinklers-
Hydraulic CalculationsFor systems greater than
40 gal (15'l L), pipe sizing shall be
determined using the TYCO Sprink-
Calc Hydraulic Program and/or the
Darcy-Weisbach and Hazen Williams
methods. Because of the densily ot
LFPTM antilreeze, the k-factor must be
adjusted and the friction loss must be
considered in the system design. The
flowing pressures are to be based upon
a k-factor calculated using the follow-
ing equation:
r-Txo= t.s+Kwl i
KA = sprinkler klactot discharying the
antifreeze solution
Kw = spinkler K-factot discharging
waler
^l A = density ol the antifreeze solution
at the tefipeature used for testing in
tb/tf
Minimum Design Pressure
The minimum design pressure of the
sprinkler system must be the minimum
required pressure for the sprinklers
used.
Fluid Sampling Valve Conneclion
The riser must be installed in an area
not subject to freezing with a minimum
temperature of 40'F (4"C). A fluid sam-
pling valve connection must be located
at the top of each system riser. The
sampling valves should be located
for ease of access to the valve by
contractors.
The sampling connection will facilitate
implementing the service requirements
outlined in the Care and Maintenance
section.

Fluid Contraclion and Expansion
Fluids expand and contract when
exposed to changes in temperatures,
resulting in changes in fluid density.
Thermal expansion shall be taken into
account when designing or retrofitting
a sprinkler system that will use LFPIM
antifreeze by use ot an expansion tank.
Table A shows the thermal expansion
or contraction of the solution at differ-
ent temperalures in sprinkler system
volumes, using the equation for sizing
the expansion chamber due to thermal
expansion in NFPA 13.
These values and the NFPA 13, l3R,
and 13D Standards lor the lnstallation
of Sprinkler Systams can be used by
the installer to determine the proper
expansion or contraction arrangement
of a sprinkler system containing LFPIM
antifreeze.
Expansion ExampleA sprinkler syslem conlain ing
50 gal (189 L) of LFPrM antifreeze is
subjected to an environmental tem-
perature of 0"F (-18"C) in the winter
months and an increase of system tem-
perature to 100"F (38'C) in the summer
months, or a temperature change
ot 100"F (38"C). This results in fluid
expansaon oi approximately 2 gal (8 L).
Contraction Example
A sprinkler syslem containing
300 gal (1136 L) of LFPrM antilreeze
is subjected to an environmental
temperature of 70"F (21"C) with a
later decrease in system tempera-
ture to -10'F (-23"C), or a temperature
change of 80'F (27'C). This results in
a fluid contraction of approximately
9.2 qal (3s L).
Expansion Tank
A listed expansion tank must be
installed in a system using LFPrM
antifreeze to account for variations in
system volume and pressure through-
out the year.
The vessel sizing should be based
on the anticipated operating condi-
lions the system will experience and
the corresponding expansion values in
Table A.

Installation
@E@
LFPIM antifreeze is pre-mixed at the
tactory per NFPA 13, 13R, 13D. Do
not dilute LFPIM antifreeze with water.
Diluting with watet or other constitu-
ents in the field can adversely impact
the properties and perlormance of the
solution. The functional life of the solu-
tion may be impacted by the end use
environmental conditions. lt is recom-
mended to only use antifteeze in closed
systems as oxygen can contribute to an
increased rate of corrosion.
New Systems
Use the following guidelines when pre-
paring a new sprinkler system for LFPIM
antifreeze installation:
l. Make certain the system has been
outfitted with air vent valve(s) and
fluid sampling valve connections
per the plans provided by the sys-
tem designer. The upper sampling
valve(s) should be easily accessi-
ble by contractors. The drain valves
should be located and oriented in a
way that allows a variety of connec-
tions with ease.
2. The system should be air-tight to
prevent leakage.
3. Use water to conduct a complete
flush of branch lines and mains to
prevent potential risks of contami-
nants, Perform a pressure test to
200 psi (13,8 ba0, per NFPA 13,
13R, 13D, to ensure no leakage is
present. Loss can be determined
by drop in gauge pressure or vi-
sual leakage. The water shall be
completely removed from the sys-
tem prior to introducing LFPrM anti-
freeze to the system.
4, Prior to filling the system with LFPrM
antifreeze, use an appropriate re-
fractometer and/or hydrometer to
test the solution to demonstrate
compliance to property ranges in
Table C. A detailed description of
an appropriate hydrometer or re-
fractometer can be lound in the
sections titled Using a Hydrometer
and Using a Refractometer, respec-
tively. ll the solution is discolored or
the container has dirt present, con-
tact Customer Services.
@I@
Storing or carrying the antifreeze solu-
tion in any container other than the
original may introduce contaminants
and reduce the functional life of the
solution.
5. Fill the system with LFPrM anti-
freeze. The use of a pump with a
backflow preventer and pressure
capabilities to get the system to the
supply pressure is recommended.
For LFPrM antifreeze to work cor-
rectly, purge as much air as pos-
sible from the system. Acceler-
ated corrosion may occur where air
pockets exist in the system.
6. After filling the system with LFP'"
antifreeze, test the system to veri-
fy the solution has not been diluted.
Take samples of the solution from
a high and low point in the system.
The test results from the samples
shall be the same before and after
installation for the installation to be
successful, Perform a pressure test
to 200 psi (13,8 ba0, per NFPA 13,
138. 13D, to ensure no leakage is
present. Loss should be deter-
mined by drop in gauge pressure or
visual leakage.
Existing Systems
Use the following guidelines when pre-
paring an existing sprinkler system for
LFPrM antif reeze installation:
1. lnspect all sprinkler drops for me-
chanical damage, corrosion, and
leakage within the system. ll any
damage is apparent, replace the
sprinkler per NFPA 25.
2. The system should be air-tight to
prevent leakage. Air vents are rec-
ommended to reduce the oxygen in
the system.
3. Use water to conduct a complete
flush of branch lines and mains to
prevent potential risks of contami-
nants. Perlorm a pressure test to
200 psi (13,8 bar), per NFPA 13,
13R, 13D. to ensure no leakage is
present. Loss should be deter-
mined by drop in gauge pressure or
visual leakage. The water shall be
completely removed lrom the sys-
tem prior to introducing LFPIM anti-
freeze to the system.
4. Prior to fillang the system with
LFPrM antitreeze, use an appropri-
ate rerractometer and/or hydrom-
eter to test the LFPrM antifreeze to
demonstrate compliance to prop-
erty ranges in Table C. A detailed
description of an appropriate hy-
drometer or refractometer can be
found in the sections titled Using
a Hydrometer and Using a Refrac-
tometer, respectively. lf the solu-
tion is discolored or the container
has dirt present, contact Customer
Services,
r@
Storing or carrying the antifreeze solu-
tion in any container other than the
original may introduce contaminants
and reduce the functional life ol the
solution.
5. Fill the system with LFPrM anti-
freeze. For LFPrM antitreeze to work
correctly, purge as much air as
possible from the system. Acceler-
ated corrosion may occur where air
pockets exist in the system.
6, After lilling the system with LFPrM
antifreeze, test the system again to
verity the solution has not been di-
luted with remaining liquids in the
system. Take samples ol the solu-
tion from a high and low point in the
system. The test results lrom the
samples shall be the same before
and after installation for the instal-
lation to be successful.
System Tag
A system tag must be present on an
antifreeze system main valve identity-
ing the lollowing:
. Type and manulacturer oI the anti-
freeze solution used
. Volume of antifreeze used
. Percent concentration by volume of
antilreeze used
ll using LFPrM anlilreeze, the percent
concentration by volume would be
100% since it is a pre-mixed solu-
tion. A tag for inspection, testing,
and maintenance can also be hung
at the system riser to record annual
testing data. Tag design is available on
www.tyco-fire.com.
Storage
Store the product in original con-
tainer and at a temperature
between 40'F (4,4'C) minimum and
90'F (32,2"C) maximum. Do not mix
the product with other liquids. Eye and
hand protection are recommended
when handling the antifreeze solution.
Care and
Maintenance
The sprinkler system owner is respon-
sible for the inspection, testing, and
maintenance of their fire protection
system and devices in compliance
with this document, as well as with the
applicable NFPA standards, in addition
to the standards ol any authority having
jurisdiction. Contact the installing con-
tractor or product manufacturer with
any questions.
It is recommended that automalic
sprinkler antifreeze systems be
inspected, tested, and maintained by a
qualified inspection, testing. and main-
tenance service.
Fluid Test
At least once a yeaL an inspection,
testing, and maintenance service shall
take a measurement of the specific
gravity or retractive index of the fluid
in the LFPrM antifreeze system. The
Iluid must be replaced il either prop-
erty deviates from that originally sup-
plied within the allowed tolerance, as
specified in Table C.
A detailed description of an appropri-
ate hydrometer or refractometer can
be found in the sections titled Using a
Hydrometer and Using a Refractometer,
respectively. A recommended hydrom-
eter, refractometer and accessories are
available ,or purchase, as listed in the
Ordering Procedure section.
It is required to have test equipment
calibrated annually to reduce the risk of
incorrect test results. Two test methods
are acceptable per NFPA 25, and either
may be used to verify that the anti-
freeze is within the specilication limits.
Using a Hydrometerl. Ensure that your hydrometer mea-
sures specific gravity. The range
of specilic gravily measurements
should cover the acceptable spe-
cific gravity range listed in Table C
and the hydrometer should have in-
crements ol at most 0.002.
2. Ensure the main supply valve is
closed prior to taking a sample to
test. lf the valve is open, supply wa-
ter will be pulled into the system
when the first sample is removed
from the system. Test separate
samples from the top of each sys-
tem and at the bottom of each sYS-
tem, or otherwise required by appli-
cable NFPA standards. lf the most
remote portion ol the system or the
interlace with the wet pipe system
is not near the top or the bottom
of the system, additional samples
must be checked.
3. Discharge a 1/2 gal (2 L) of fluid
from the fluid sampling valve con-
nection. Collect and seal the sam-
ple in a clean and dry 3/4 gal (3 L)
or larger container. Allow the sam-
ple to warm until it reaches the min-
imum temperature in Table C.
4. Once the solution reaches the mini-
mum temperature, fill the 500 ml
calibrated cylinder with the solu-
tion and gently insert the hydrom-
eter into the cylinder to allow it to
float. Fluid may be added to the
cylinder until the hydrometer is
floating. Note the speciric gravity as
shown on the hydrometer. Check
the temperature using an appropri-
ate thermometer.
5. Verify the specilic gravity falls with-
in ihe acceptable range listed in Ta-
ble C. lf the test results for all the
samples are within the acceptable
ranges, the inspection is complete.
6. lI the test results from any of the
samples lall outside ol the accept-
able ranges, drain out the system,
and pump in new LFPrM antifreeze.
Take samples and test again. lf the
samples continue to fall outside of
the acceptable specifications, then
the system shall be emptied and
vacuumed clean ol any remaining
fluid. Recharge the system per the
Existing System lnstallation sec-
tion. lf the samples fall within the
acceptable range, top olf the sys-
tem lo replace the liquid removed
for the samples.
Using a Refractometer
1. Ensure that your refractometer is
temperalure compensating and
that it measures refractive index.
The range of refractive index mea-
surements should cover the ac-
ceptable relractive index range list-
ed in Table C and the refractometer
should have increments of at most
0.0001.
2. Ensure the main supply valve is
closed prior to taking a sample to
test. lf the valve is open, supply wa-
ter will be pulled into the syslem
when the tirst sample is removed
from the system. Test separate
samples from the top of each sys-
tem and at the bottom of each sys-
tem, or otherwise required by appli-
cable NFPA standards. ll the most
remote portion of the system or the
interface with the wet pipe system
is not near the top or the bottom
of the system, additional samples
must be checked.
3. Discharge a 1/2 gal (2 L) of fluid
from the fluid sampling valve con-
nection. Collect and seal the sam-
ple in a clean and dry 3/4 gal (3 L)
or larger container,
4. To measure the refractive index,
use a digital refractometer that is
temperature compensating. Fill the
well in the refractometer with solu-
tion and shut the cover. Note the
refractive index as shown on the
refractometer.
5. Verify the refractive index lalls with-
in the acceptable range listed in Ta-
ble C. lf the test results for all the
samples are within the acceptable
ranges, the inspection is complete.
6. lf the lesl results from any of the
samples fall outside of the accept-
able ranges, drain out the system,
and pump in new LFPrM antifreeze.
Take samples and test again. lf the
samples continue to fall outside o,
the acceptable specifications, then
the system shall be emptied and
vacuumed clean of any remaining
fluid. Recharge the system per the
Existing System lnstallation sec-
tion. lf the samples fall within the
acceptable range, top ofl the sys-
tem to replace the liquid removed
for the samples.
@
Contaminants or other foreign materials
within asprinkler system may adversely
impact the properties and pertormance
of LFPIM antilreeze. Refer to the lnstal
lation section for instructions on flush-
ing and recharging the system if the
solution falls outside of the acceptable
range since the last inspection.
@
Use of LFPTM antifreeze shall be in con-
formance with all state and local health
and environmental regulations for the
location where it is installed. lf a small
amount of antifreeze solution is spilled,
absorbent towels are recommended to
clean up spill, Towels used to clean up
spill can be disposed of in the garbage.
Use caution following a spill as the floor
may remain slippery in the arca of the
spill. Consult with a local waste water
treatment plant or council for informa-
tion on procedures to lollow for the dis-
posal of large amounts of waste water
Disposal
Any disposal of LFPIM antifreeze shall
be in conformance with all federal,
