RAPID RESPONSE Series LFII Residential Sprinklers
5.8 K-factor Horizontal Sidewall, NFPA 13 Optimized
Wet Pipe Systems
General
Description
The TYCO RAPID RESPONSE Series
LFII (TY4334) Residential Horizontal
Sidewall Sprinklers are decorative,
fast response, frangible bulb sprin-
klers designed for use in residential
occupancies such as homes, apart-
ments, dormitories, and hotels. When
enhanced flow characteristics for resi-
dential portions of any occupancy per
NFPA 13 is the major consideration, the
Series LFII (TY4334) should be the first
choice.
When higher flow demands are
required for residential sprinklers used
in an NFPA 13 design, the large 5.8
K-factor of the Series LFII (TY4334) is
an attractive choice. Although mostly
intended where residential sprinklers
are to be used in an NFPA 13 design,
the Series LFII (TY4334) can also be
used in wet pipe residential sprin-
kler systems for one- and two-family
dwellings and mobile homes per NFPA
13D, and wet pipe residential sprinkler
systems for residential occupancies up
to and including four stories in height
per NFPA 13R.
The recessed version of the Series LFII
(TY4334) is intended for use in areas
with finished walls. It employs a two-
piece Style 20 Recessed Escutcheon.
The Recessed Escutcheon provides
1/4 in. (6,4 mm) of recessed adjustment
or up to 1/2 in. (12,7 mm) of total adjust-
ment from the flush mounting surface
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
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.

position. The adjustment provided by
the Recessed Escutcheon reduces the
accuracy to which the pipe nipples to
the sprinklers must be cut.
The Series LFII (TY4334) has been
designed with heat sensitivity and
water distribution characteristics
proven to help in the control of residen-
tial fires and to improve the chance for
occupants to escape or be evacuated.
Corrosion-resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion-resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable Approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these coatings for any given
corrosive environment. The effects of
ambient temperature, concentration of
chemicals, and gas/chemical velocity
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
NOTICE
The Series LFII (TY4334) Residen-
tial Horizontal Sidewall Sprinklers
described herein must be installed
and maintained in compliance with this
document, as well as with the applica-
ble standards of the NATIONAL FIRE
