RAPID RESPONSE Series LFII Residential
4.9 K-factor Concealed Pendent Sprinkler
Flat Plate, Wet Pipe and Dry Pipe Systems
General
Description
The TYCO RAPID RESPONSE Series
LFII Residential 4.9K Concealed
Pendent Sprinklers (TY3596) are dec-
orative, fast response, fusible solder
sprinklers designed for use in residen-
tial occupancies such as homes, apart-
ments, dormitories, and hotels.
The cover plate assembly conceals
the sprinkler operating components
above the ceiling. The flat profile of the
cover plate provides the optimum aes-
thetically appealing sprinkler design.
In addition, the concealed design
of the Series LFII Residential Con-
cealed Pendent Sprinklers provides
1/2 in. (12,7 mm) vertical adjustment.
This adjustment provides a measure
of flexibility when cutting fixed sprin-
kler drops.
The Series LFII Residential Concealed
Pendent Sprinklers are intended for use
in the following scenarios:
• Wet and dry pipe residential sprin-
kler systems for one and two fam-
ily dwellings and mobile homes per
NFPA 13D
• Wet and dry pipe residential sprin-
kler systems for residential occupan-
cies up to and including four stories
in height per NFPA 13R
• Wet and dry pipe sprinkler systems
for the residential portions of any
occupancy per NFPA 13
The Series LFII Residential Concealed
Pendent Sprinklers have been designed
with heat sensitivity and water distri-
bution characteristics proven to help
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

in the control of residential fires and to
improve the chance for occupants to
escape or be evacuated.
The Series LFII Residential Con-
cealed Pendent Sprinklers (TY3596)
are shipped with a Disposable Protec-
tive Cap. The Protective Cap is tem-
porarily removed for installation, and
then it can be replaced to help protect
the sprinkler while the ceiling is being
installed or finished. The tip of the Pro-
tective Cap can also be used to mark
the center of the ceiling hole into the
plaster board, ceiling tiles, and so on,
by gently pushing the ceiling product
against the Protective Cap. When the
ceiling installation is complete the Pro-
tective Cap is removed and the Cover
Plate Assembly is installed.
Dry Pipe System Application
The Series LFII Residential Concealed
Pendent Sprinklers offer a laboratory
approved option for designing dry pipe
residential sprinkler systems, whereas,
most residential sprinklers are labora-
tory approved for wet systems only.
Through extensive testing, it has
been determined that the number of
design sprinklers (hydraulic design
area) for the Series LFII Residential
Concealed Pendent Sprinklers need
not be increased over the number of
design sprinklers (hydraulic design
area) as specified for wet pipe sprinkler
systems, as is accustomed for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series LFII Residen-
tial Concealed Pendent Sprinklers offer
the features of non-water filled pipe in
addition to not having to increase the
number of design sprinklers (hydraulic
design area) for systems designed to
NFPA 13, 13D, or 13R.
