HOR. & REC. HOR. SIDEWALL SPRINKLERS, RESIDENTIAL
MODEL F685 DESIGNER, BULB TYPE, 3.5 K-FACTOR, 155°F & 175°F
GENERAL DESCRIPTION
The 3.5 K-factor, Model F685 Designer
Residential Horizontal and Recessed
Horizontal Sidewall Sprinklers (Ref.
Figure A) are automatic sprinklers of
the frangible bulb type. They are 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
to four stories in height per NFPA
13R, and
• wet pipe sprinkler systems for the
residential portions of any occu-
pancy per NFPA 13.
They are designed for installation
along a wall or lintel and just beneath
a smooth and level ceiling. Horizontal
sidewall sprinklers are generally used
in lieu of pendent or upright sprinklers
because of aesthetic, building con-
struction, or installation economy con-
siderations.
The recessed versions of the Model
F685 Sprinkler are obtained by utiliz-
ing the Model F705 Recessed Es-
cutcheon (Ref. Figures A and B-2). The
F705 Recessed Escutcheon provides
1/4 inch (6,4 mm) of recessed adjust-
ment or up to 1/2 inch (12,7 mm) of
total adjustment from the flush sidewall
position.
The F705 has a separable two-piece
design which allows installation of the
sprinklers and pressure testing of the
fire protection system, prior to wall
construction and/or application of a fin-
ish coat to the wall. They also permit
refinishing of a wall surface without
having to first shut down the fire pro-
tection system and remove the sprin-
klers.
The F685 Sprinklers have been de-
signed to operate with a particular tem-
perature rating and heat responsive
thermal characteristic, as well as to
discharge water in a specific pattern
and quantity per square foot relation-
ship. The combination of the perform-
ance characteristics which are associ-
ated with the F685 Sprinklers have
