Description
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) 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 Residential Sprinklers
(TY2284) should be the first choice.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet and dry pipe residential sprinkler
systems for one- and two-family
dwellings and mobile homes per
NFPA 13D
• wet and dry pipe residential sprinkler
systems for residential occupancies
up to and including four stories in

• wet and dry pipe sprinkler systems
for the residential portions of any
occupancy per NFPA 13
The flush design of the Series LFII Resi-

Dry Pipe System Application

The Series LFII Residential Flush
Pendent Sprinklers offers a laboratory
approved option for designing dry pipe
residential sprinkler systems, whereas,
most residential sprinklers are labora-
tory 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 Flush
Pendent Sprinklers (TY2284) need
not be increased over the number of
design sprinklers (hydraulic design
area) as specified for wet pipe sprinkler
systems, as is customary for density/
area sprinkler systems designed per
NFPA 13.
Consequently, the Series LFII Residen-
tial Sprinklers (TY2284) offer the fea-
tures 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.
