Model DSB-2
Dry Sprinkler Boot
For Use With TFP Dry Type Sprinklers
General
Description
The Tyco
Model DSB-2 Dry Sprin-
®
kler 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 clear-
ance 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 great-
er 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
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 oth-
er 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
eliminating the occurrence of crack-
ing of some commonly used sealants,
that subsequently allows the passage
of moist air.

Use of the Model DSB-2 Dry Sprinkler
Boot with non-TFP Dry Type Sprinklers
will void the warranty. Failure may re-
sult due to dimensional differences in
the outside diameter of the barrel. The
DSB-2 has not been tested with any
non-TFP Dry Type Sprinklers with re-
clearance
space
gard to fit or performance.
Physical Characteristics
The Boot is EPDM, the Strap Ties
are nylon, and the Adhesive is ethyl
