General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Horizontal Sidewall
Sprinklers (TY1334) are decorative,
fast response, frangible bulb sprinklers
designed for use in residential occupan-
cies such as homes, apartments, dormi-
tories, and hotels. When aesthetics and
optimized fl ow characteristics are the
major consideration, the Series LFII
Residential Sidewall Sprinklers (TY1334)
should be the fi rst choice.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet and dry pipe residential sprinkler
systems for one- and two-family
dwellings and mobile homes per
NFPA 13D
• wet and dry pipe residential sprinkler
systems for residential occupancies
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 recessed version of the Series
LFII Residential Sprinklers is intended
for use in areas with fi nished walls.
It employs a two-piece Style 20
Recessed Escutcheon. The Recessed
Escutcheon provides 1/4 inch (6,4 mm)
of recessed adjustment or up to 1/2 inch
(12,7 mm) of total adjustment from the
fl ush mounting surface position. The
adjustment provided by the Recessed

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
components. Improper handling and
installation can permanently damage a
sprinkler system or its components and
cause the sprinkler to fail to operate in
a fi re situation or cause it to operate
prematurely.

Escutcheon reduces the accuracy to
which the pipe nipples to the sprinklers
must be cut.
The Series LFII Residential Sprinklers
have been designed with heat sensitivity
and water distribution characteristics
proven to help in the control of residen-
tial fi res and to improve the chance for
occupants to escape or be evacuated.
Dry Pipe System Application
The Series LFII Residential Horizontal
and Recessed Horizontal Sidewall
Sprinklers offers a laboratory approved
option for designing dry pipe residen-
tial sprinkler systems, whereas, most
residential sprinklers are laboratory
approved for wet systems only.
Through extensive testing and as refer-
enced in U.S. Patent 7,712,543, it has
been determined that the number of
design sprinklers (hydraulic design area)
for the Series LFII Residential Sprinklers
need not be increased over the number
of design sprinklers (hydraulic design
area) as specifi ed for wet pipe sprinkler
systems, as is accustomed for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series
Residential Sprinklers offer the features
of non-water fi lled 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. Non-water fi lled pipe will permit
options for areas sensitive to freezing
