General
Description
The TYCO RAPID RESPONSE Series
LFII Residential Flush Horizontal Side-
wall Sprinklers (TY2384) are decorative,
fast response, fusible solder sprinklers
designed for use in residential occu-
pancies such as homes, apartments,
dormitories, and hotels. When aes-
thetics is the major consideration, the
Series LFII Sprinklers (TY2384) should
be the first choice.
The Series LFII Residential Sprinklers
(TY2384) are intended for use in the fol-
lowing scenarios:
• wet-pipe residential sprinkler sys-
tems for one- and two family dwell-
ings and manufactured 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 flush design of the Series LFII Resi-
dential Sprinklers (TY2384) features a
separable escutcheon providing 3/16
in. (4,8 mm) horizontal adjustment. This
adjustment reduces the accuracy to
which the pipe nipples to the sprinklers
must be cut to help assure a perfect fit
installation.

Operation
The sprinkler assembly contains a
small fusible solder element. When
exposed to sufficient heat from a fire,
the solder melts and enables the inter-
nal components of the sprinkler to fall
away. At this point the sprinkler acti-
vates with the deflector dropping into
its operated position (Ref. Figure 1C),
permitting water to flow.
