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 occu-
pancies such as homes, apartments,
dormitories, and hotels. When aesthet-
ics and optimized flow characteristics
are the major consideration, the Series
LFII Residential Sidewall Sprinklers
(TY1334) should be the first choice.
The Series LFII Residential 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 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 finished 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 flush mounting surface posi-
tion. The adjustment provided by the
Recessed Escutcheon reduces the

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.

accuracy to which the pipe nipples to
the sprinklers must be cut.
The Series LFII Residential Sprinklers
have been designed with heat sensitiv-
ity 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.
Dry Pipe System Application
The Series LFII Residential Horizon-
tal 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, it has been
determined that the number of design
sprinklers (hydraulic design area) for
the Series LFII Residential Horizon-
tal Sidewall Sprinklers (TY1334) 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 Resi-
dential 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. Non-water filled pipe will permit
options for areas sensitive to freezing.

Sidewall Sprinklers described herein
