General
Description
TYCO RAPID RESPONSE Series
LFII Residential 4.9K Pendent and
Recessed Pendent Sprinklers (TY2236)
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 (TY2236) 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 ceilings when
used with one of the following:
• A two-piece Style 15 Recessed
Escutcheon with recessed adjust-
ment up to 5/8 in. (15,9 mm) from
the flush pendent position.
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
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.

• A two-piece Style 20 Recessed
Escutcheon with recessed adjust-
ment up to 1/2 in. (12,7 mm) from
the flush pendent position.
The adjustment provided by either
Recessed 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.
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.
