General
Description
The TYCO Model DSB-2 Dry Sprinkler
Boot (Ref. Figure 1) is designed for use
with TFP Dry Type Sprinklers. When
properly installed, it will help close the
air gap created by the clearance hole
through a wall or ceiling through which
the dry type sprinkler has penetrated.
The DSB-2 is intended predominately
for use with clearance holes through
freezer ceiling structures. In these
types of installations, due to the greater
temperature difference between the
inside and outside of the freezer than
found with other type installations, the
potential for the formation of conden-
sation in the sprinkler and subsequent
ice build-up is increased. If this con-
densation is not controlled, ice build-up
can occur that might damage the dry
type sprinkler and/or prevent proper
operation in a fire situation.
The DSB-2 is intended to help stop the
air exchange between the inside and
outside of the freezer (or any other type
of similar construction) to help prevent
transfer of moist air into the freezer
space. The use of the DSB-2 provides
a quick and efficient means of closing
the air gap created by the dry type
sprinkler clearance hole. The DSB-2
provides the added feature of eliminat-
ing the occurrence of cracking of some
commonly used sealants, that subse-
quently allows the passage of moist air.
NOTICE
The Model DSB-2 Dry Sprinkler Boot
described herein must be installed
and maintained in compliance with
this document, as well as with the
applicable standards of the NATIONAL
FIRE PROTECTION ASSOCIATION, in
addition to the standards of any other
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 con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
Technical
Data
Approvals
The TYCO Model DSB-2 Dry Sprin-
kler Boot does not require laboratory
approval to be installed in accordance
with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION. The use of the DSB-2 does
not alter any of the applicable labo-
ratory approvals for TFP Dry Type
Sprinklers.
The 2007 edition of NFPA 13, Section
8.4.10.2 requires that dry sprinklers
connected to wet pipe sprinkler
systems protecting insulated freezer
structures, the clearance space around
the sprinkler barrel shall be sealed.

NOTE: Use of the Model DSB-2 Dry
Sprinkler Boot with non-TFP Dry Type
Sprinklers will void the warranty. Failure
may result due to dimensional differ-
ences in the outside diameter of the
barrel. The DSB-2 has not been tested
with any non-TFP Dry Type Sprinklers
with regard to fit or performance.
Physical Characteristics
The Boot is EPDM, the Strap Ties are
nylon, and the Adhesive is ethyl cyano-
acrylate based. The adhesive is formu-
lated for instant bonding of the Boot to
metal, plastic, or rubber surfaces.
Design
Criteria
There are four items to be considered:
Dry Type Sprinklers, Clearance Hole,
Exposure Length, and Sprinkler Fitting.
Dry Type Sprinklers
This Technical Data section provides
a list of all of the compatible dry type
sprinklers and their associated techni-
cal data sheets. Refer to the applicable
technical data sheet for installation and
maintenance information for the sprin-
kler being utilized.

NOTICE
The TFP Dry Type Sprinklers must be
installed and maintained in compli-
ance with the applicable technical data
sheet. Failure to do so may impair the
performance of these devices.
Clearance Hole
The Model DSB-2 Dry Sprinkler
Boot may be used with a maximum
2-1/2 in. (63,5 mm) diameter clearance
hole (i.e., the diameter of the hole in
the ceiling or wall being penetrated by
the dry type sprinkler, Ref. Figures 1 or
2). Based on the diameter of the Dry
Type Sprinkler Barrel, the designated
maximum clearance hole will com-
pensate for non-centering of the Dry
Type Sprinkler Barrel within the clear-
ance hole. Where centering can be
maintained, a clearance hole as large
as 3 in. (76,2 mm) in diameter can be
accommodated.
NOTE: The clearance hole adjacent
to the DSB-2 cannot be larger than
2-1/2 in. (63,5 mm) diameter for a
non-concentric installation or 3 in.
(76,2 mm) diameter for a concentric
installation. Otherwise, the DSB-2
cannot perform as intended by closing
the air gap.
NOTE: Clearance holes greater than
specified cannot be filled in with foam
insulation, etc. In order for the DSB-2
to be effective in closing the air gap it
must seat and seal against the smooth
material of the ceiling or wall.
Exposure Length
When Dry Sprinklers are to be used in
wet pipe sprinkler systems protecting
areas subject to freezing temperatures
(e.g., sprinkler drops into freezers), con-
sideration must be given to the appro-
priate length of the sprinkler that will
prevent freezing of the water in the con-
necting pipes due to conduction. When
the temperature surrounding the wet
pipe sprinkler system is maintained at
a minimum temperature of 40°F (4°C),
the following are the minimum recom-
mended lengths between the face of
the sprinkler fitting and the outside sur-
face of the protected area (i.e., length
exposed to minimum ambient tempera-
ture of 40°F (4°C) — Ref. Figure 3):
• 12 inches (300 mm) when the tem-
perature within the protected area is
-20°F (-29°C)
• 18 inches (450 mm) when the tem-
perature within the protected area is
-40°F (-40°C)
• 24 inches (600 mm) when the tem-
perature within the protected area is
-60°F (-51°C)
For protected area temperatures
between those given above, the
minimum recommended length from

the face of the fitting to the outside of
the protected area may be determined
by interpolating between the indicated
values.
NOTE: The temperature within the
protected area must be based on
the lowest expected temperature.
For example: a freezer may be rated
at -20°F (-29°C), yet the condenser is
emitting -30°F (-35°C). The dry sprin-
kler length must be calculated based
on the lower temperature of -30°F
(-35°C).
Sprinkler Fitting
TFP Dry Type Sprinklers must be
installed in the 1 in. NPT outlet or run
of a malleable or cast iron threaded tee
as described in the applicable technical
data sheets. With reference to Figure
4 and in conjunction with use in a wet
pipe system, the sprinkler drop may be
installed as shown. The information in
Figure 4 may only be used where the
sprinkler fitting and water filled pipe
above the sprinkler fitting is not subject
to freezing. In areas subject to freez-
ing, the pipe connected to the dry type
sprinkler must be configured to allow
complete drainage as shown in Figure
5.
Installation
The TYCO Model DSB-2 must be
installed in accordance with this
section.
WARNING
The Adhesive contains cyanoacrylate
ester. Irritation will occur when inhaled.
This adhesive bonds skin in seconds.
Contact through clothing may cause
burns. EYE IRRITANT.
Always refer to the Material Safety Data
Sheet for additional adhesive handling
recommendations. The Material Safety
Data Sheet should be obtained from
the adhesive manufacturer via their
web site noted on the adhesive con-
tainer label before using the adhesive.
In case of skin contact, flush with
water, and for eye contact seek medical
attention.
Provide adequate ventilation in area
of usage. When possible ventilation
should be achieved by the use of local
exhaust ventilation and good general
ventilation. Vapors are heavier than air,
therefore, downward ventilation should
be used. When handling cyanoacrylate
adhesives, goggles or safety glasses
should always be worn. Polyethylene
gloves should be used to protect the
hands.

WARNING
DO NOT USE RUBBER OR CLOTH
GLOVES. RUBBER GLOVES WILL
BOND WHEN BROUGHT IN CONTACT
WITH THE ADHESIVE AND POROUS
COTTON GLOVES WILL ABSORB THE
ADHESIVE AND BOND THE GLOVES
TO THE SKIN.
Step 1. Prepare the clearance hole per
the applicable TFP Dry Sprinkler Tech-
nical Data Sheet.
Step 2. Insert the dry sprinkler through
the clearance hole and slide the Boot
over threaded inlet of the dry sprinkler.
NOTE: When installing on Series DS-2
Dry Sprinklers, the Boot will require
stretching. The use of a grooved cou-
pling gasket lubricant will ease installa-
tion. Use only a petroleum free silicone
grooved coupling gasket lubricant to
avoid freezing of the Dry Sprinkler Boot
to the Dry Sprinkler.
NOTE: When sliding the Boot over the
length of the Dry Sprinkler, sliding is
easily accomplished by slightly squeez-
ing the Boot around the cone area.
Step 3. Thread the dry sprinkler into
the sprinkler fitting per the applicable
TFP Dry Sprinkler technical data sheet.
NOTE: Refer to the sprinkler technical
data sheet for tightening torque spec-
ifications. The use of higher levels of
torque then specified may distort the
sprinkler inlet with consequent leakage
or impairment of the sprinkler.
Step 4. Clean the contact surfaces of
the Boot and the building (ceiling or
wall) structure with a damp cloth. Moist
surfaces will aid in a quick adhesion.
NOTE: Use only a cloth that has been
dampened with water. The use of other
cleaning techniques, solvents, etc.
may render the adhesive incapable of
sealing.
Step 5. Apply the provided Adhesive
to the building structure in a zig-zag
pattern. Refer to Warning regarding
the adhesive.
Step 6. Slide the Boot so that it comes
in contact with the building structure,
and then press the Boot firmly against
the building structure to help ensure
that the Adhesive is fully applied to
both surfaces.
NOTE: When sliding the Boot over the
length of the Dry Sprinkler, sliding is
easily accomplished by slightly squeez-
ing the Boot around the cone area.
Step 7. Wait two minutes to allow the
Adhesive to sufficiently cure and then
apply the two Strap Ties. The Strap
Ties are to be applied to the straight
section of the Boot as shown in Figure
1 and so that the ends are on opposing
sides of the Boot.
NOTE: The ties are to be pulled suf-
ficiently tight to the point that there is
no gap between Dry Sprinkler Boot
and the Dry Sprinkler. When properly
installed a paper clip or wire of similar
dimension cannot be slipped between
the Dry Sprinkler Boot and the Dry
Sprinkler.
