General
Description
The TYCO Series LFII Residential Hor-
izontal Sidewall Sprinklers (TY2334)
are decorative, fast response, frangi-
ble bulb sprinklers designed for use
in residential occupancies such as
homes, apartments, dormitories, and
hotels. When aesthetics and optimized
flow characteristics are the major con-
sideration, the Series LFII Residential
Sprinklers (TY2334) should be the first
choice.

The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet pipe residential sprinkler sys-
tems for one-and two-family dwell-
ings and mobile homes per NFPA
13D
• wet pipe residential sprinkler sys-
tems for residential occupancies up
to and including four stories in height
per NFPA 13R
• wet pipe sprinkler systems for the
residential portions of any occu-
pancy per NFPA 13
The recessed version of the Series
LFII Residential Sprinklers 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 adjustment from the
flush mounting surface 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 Residential Sprinklers
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.
