Description
TYCO RAPID RESPONSE Series
LFII Residential 4.9K Pendent and
Recessed Pendent Sprinklers (TY2234)
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 (TY2234) 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 ceilings.
It employs a two-piece Style 20
Recessed Escutcheon. The Recessed
Escutcheon provides
(6,4 mm) of recessed adjustment or up
to 1/2 inch (12,7 mm) of total adjustment
from the flush ceiling position. The

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-

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

Escutcheon reduces the accuracy to
which the pipe drops to the sprinklers
must be cut.
The Series LFII Residential Sprinklers
have been designed with heat sensi-
tivity and water distribution charac-
teristics proven to help in the control
of residential fires and to improve the
chance for occupants to escape or be
evacuated.
Dry Pipe System Application
The Series LFII Residential Pendent
and Recessed Pendent Sprinklers
offers a laboratory approved option
for designing dry pipe residential sprin-
kler 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 Pendent and
Recessed Pendent Sprinklers (TY2234)
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
design area) for systems designed to
NFPA 13, 13D, or 13R.
