Tyco DSB-1 User manual

General
Description
The Model DSB-1 Dry Sprinkler Boot
(Ref. Figure 1) is designed for use with
TFP Dry Type Sprinklers. When prop-
erly 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.
Predominately, the DSB-1 is intended
for use with clearance holes through
freezer ceiling structures. In these
types of installations, due to the
greater temperature difference be-
tween the inside and outside of the
freezer than found with other type in-
stallations, the potential for the forma-
tion of condensation in the sprinkler
and subsequent ice build-up is in-
creased. If this condensation is not
controlled, ice build-up can occur
which might damage the dry type
sprinkler and/or prevent proper opera-
tion in a fire situation.
TheDSB-1isintendedtohelpstopthe
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-1
provides a quick and efficient means
to closing the air gap created by the
dry type sprinkler clearance hole. The
DSB-1 provides the added feature of
eliminating the occurrence of cracking
of some commonly used sealants,
where the cracking of these sealants
subsequently allows the passage of
moist air.

DryTypeSprinklers.This Technical
Data section provides a list of all of the
compatible dry type sprinklers and
their associated technical data sheets.
Refer to the applicable technical data
sheet for installation and maintenance
information for the sprinkler being util-
ized.
NOTE
The TFP Dry Type Sprinklers must be
installed and maintained in compli-
ancewith theapplicabletechnicaldata
sheet. Failure to do so may impair
the performance of these devices.
Clearance Hole. The Model DSB-1
Dry Sprinkler Boot may be used with a
maximum 1-3/4 inch(44,5 mm)diame-
ter clearance hole (i.e., the diameter of
the hole in the ceiling or wall being
penetrated by the dry type sprinkler,
reference Figure 1). Based on the
diameter of the Dry Type Sprinkler
Barrel, the designated maximum
clearance hole will compensate for
non-centering of the Dry Type Sprin-
kler Barrel within the clearance hole.
Where centering can be maintained, a
clearance hole as large as 2-1/4
inches (57,2 mm) in diameter can be
accommodated.
Where necessary, the clearance hole
may need to be enlarged adjacent to
the sprinkler end of the dry pendent
sprinkler. For example as shown in
Figure 2, a 2-1/2 inch (63,5 mm) di-
ameter by 2-1/4 inch (57,2 mm) deep
counterbore is necessary to facilitate
installation of the DS-C or DS-ECC
Dry Pendent Concealed Sprinklers.
NOTES
The clearance hole adjacent to the
DSB-1 cannot be larger than 1-3/4
inch(44,5mm)diameterforanon-con-
centric installation or 2-1/4 inch (57,2
mm) diameter for a concentric installa-
tion.Otherwise,theDSB-1cannotper-
form as intended by closing the air
gap.
Clearance holes greater than speci-
fied cannot be filled in with foam insu-
lation, etc. In order for the the DSB-1
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 Sprin-
klers are to be used in wet pipe sprin-
kler systems protecting areas subject
to freezing temperatures (e.g., sprin-
klerdrops intofreezers),consideration
must be given to the appropriate
length of the sprinkler that will prevent
freezing of the water in the connecting
pipes due to conduction. When the
temperature surrounding the wet pipe

following are the minimum recom-
mended lengths between the face of
thesprinklerfittingandthe outsidesur-
face of the protected area (i.e., length
exposed to minimum ambient tem-
perature 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 be-
tween those given above, the mini-
mum 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 ex-
pected temperature.
For example: a freezer may be rated
at -20°F/-29°C, yet the condenser is
emitting-30°F/-35°C.Thedrysprinkler
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
inch NPT outlet or run of a malleable
or cast iron threaded tee as described
in the applicable Technical Data
Sheets. With referenceto Figure 4 and
in conjunction with use in a wet pipe
system, the sprinkler drop may be in-
stalled as shown. The information in
Figure 4 may only be used where the
sprinkler fitting and water filled pipe
abovethesprinklerfittingisnotsubject
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 Model DSB-1 must be installed in
accordance with the following instruc-
tions:

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 container la-
bel 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, down-
ward ventilation should be used.
When handling cyanoacrylate adhe-
sives, goggles or safety glasses
should always be worn. Polyethyl-
ene gloves should be used to pro-
tect 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. Preparetheclearanceholeper
theapplicableTFPDrySprinklerTech-
nical Data Sheet.
Step 2. Insert the dry sprinkler through
the clearance hole and slide the Boot
over threaded inlet ofthe dry sprinkler.
When installing on Series DS-2 Dry
Sprinklers, the Boot will require
stretching. The use of a grooved cou-
pling gasket lubricant will ease instal-
lation. Use only a petroleum free sili-
cone grooved coupling gasket
lubricant to avoid freezing of the Dry
Sprinkler Boot to the Dry Sprinkler.
When sliding the Boot over the length
of the Dry Sprinkler, sliding is easily
accomplished by slightly squeezing
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.
Refer to the sprinkler technical data
sheet for tightening torque specifica-
tions. The use of higher levels of
torque then specified may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
Step 4. Clean the contact surfaces of
the Boot and the building (ceiling or
wall)structure withadampcloth.Moist
surfaces will aid in a quick adhesion.
Use only a cloth that has been damp-
ened 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.
When sliding the Boot over the length
of the Dry Sprinkler, sliding is easily
accomplished by slightly squeezing
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 thatthe ends are on opposing
sides of the Boot.
The ties are to be pulled sufficiently
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 dimen-
sion cannot be slipped between the
Dry Sprinkler Boot and the Dry Sprin-
kler.
