FLUSH PENDENT SPRINKLERS, RESIDENTIAL
MODEL F990 AQUARIUS@', 4.2 K-FACTOR
The 4.2 K-factor, Model F990 Aquarius
Residential Pendent Sprinklers (Ref.
Figure A) are automatic sprinklers of
the fusible solder type. They are low
profile, flush mounting sprinklers
which are intended to be used in
. 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
:p,;Tnitories in height per NFPA
. wet pipe sprinkler systems for the
residential portions of any occu-
pancy per NFPA 13.
Small and attractive, the F990 Sprink-
lers are installed with either a Push-on
or Clamp-on Escutcheon Plate and
feature a smooth, low profile, flush-
style design with an aesthetically
pleasing appearance that blends in
with all types of surroundings.
The Push-on Escutcheon Plates, as
described in the Technical Data sec-
tion, are intended primarily for use with
steel pipe or copper tubing. The l/4
inch adjustment provided by the Push-
on Escutcheon Plate and the addi-
tional l/4 inch of adjustment that can
be obtained by use of the Extension
reduces the accuracy to which the
sprinklers must be positioned. The 3
inch outside diameter of the Push-on
Plate also contributes to the ease of
installation by covering offset clear-
ance holes.
Clamp-on Escutcheon Plates, which
are designed for use with plastic pipe
fire protection systems, are described
in Technical Data Sheet TD810.
The F990 Sprinklers have been de-
signed to operate with a particular fus-
ible element temperature rating and
heat sensitivity characteristic, as well
as to discharge water in a specific pat-
tern and quantity per square foot rela-
tionship. The combination of. the per-
formance characteristics which are
associated with the F990 Sprinklers
have been proven to help in the control
of residential type fires and, therefore,
to improve the chance for occupants to
escape or be evacuated.
Fire sprinkler systems are not a substi-
tute for intelligent fire safety aware-
ness or construction materials and
practices required by building codes.
