RAPID RESPONSE Series LFII Residential Sprinklers
3.0 K-factor Pendent
Wet Pipe Systems
General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Pendent Sprinklers
(TY1234) are decorative, fast response,
frangible bulb sprinklers designed for
use in residential occupancies such as
homes, apartments, dormitories, and
hotels. When aesthetics and optimized
flow characteristics are key consider-
ations, the Series LFII (TY1234) should
be the first choice.
The 3.0 K-factor of the Series LFII Res-
idential Pendent Sprinkler has been
designed to optimize flows (that is, to
avoid over discharging) specifically for
small coverage areas up to 14 ft. x 14
ft. (4,3 m x 4,3 m). The required resi-
dential flow rates can then be delivered
with the use of smaller pipe sizes and
reduced water supply requirements.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet pipe residential sprinkler systems
for one-and two-family dwellings and
mobile homes per NFPA 13D
• wet pipe residential sprinkler systems
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
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.

The recessed version of the Series
LFII Residential Pendent Sprinkler is
intended for use in areas with finished
ceilings. It employs a two-piece Style
20 Recessed Escutcheon.
The Recessed Escutcheon provides
1/4 inch (6,4 mm) of recessed adjust-
ment or up to 1/2 inch (12,7 mm) of
total adjustment from the flush ceiling
position. The adjustment provided by
the Recessed Escutcheon reduces the
accuracy to which the pipe drops to the
sprinklers must be cut.
The Series LFII Residential Pendent
Sprinkler has been designed with heat
sensitivity and water distribution char-
acteristics proven to help in the control
of residential fires and to improve the
chance for occupants to escape or be
evacuated.
