CONCEALED PENDENT SPRINKLER with 1/2" ADJUSTMENT
MODEL F690 DESIGNER
QUICK RESPONSE, 3 mm BULB TYPE, 1/2" ORIFICE, 1/2" NPT
GENERAL DESCRIPTION
The 1/2 inch (15 mm) orifice Model
F690 Designer, Quick Response Con-
cealed Pendent Sprinklers (Ref.Figure
A) are pendent automatic sprinklers of
the frangible bulb type.They are “quick
response - standard orifice spray
sprinklers” intended for use in fire
sprinkler systems designed in accord-
ance with the standard installation
rules recognized by the applicable
Listing or Approval agency (e.g. UL
Listing is based on NFPA 13 require-
ments). The F690 produces a hemi-
spherical water distribution pattern be-
low the deflector. Each unit includes a
Cover Plate Assembly which conceals
the sprinkler operating components
above the ceiling.
The small Cover Plate is flat with a low
profile which blends in with the ceiling
for an aesthetically pleasing appear-
ance. Standard finishes for the Cover
Plate are satin chrome plated and
painted white. Other factory applied
painted finishes for the Cover Plate are
available on special order.
The separable two-piece design of the
Cover Plate and Mounting Cup As-
semblies allows installation of the
sprinklers and pressure testing of the
fire protection system prior to installa-
tion of a suspended ceiling or applica-
tion of the finish coating to a fixed
ceiling.The separable design also per-
mits removal of suspended ceiling
panels for access to building service
equipment, without having to first shut
down the fire protection system and
remove sprinklers.
Also, the separable two-piece design
of the the F690 Concealed Sprinkler
provides for 1/2 inch of vertical adjust-
ment, to reduce the accuracy to which
the length of fixed pipe drops to the
sprinklers must be cut.
Each sprinkler is shipped with a dam-
age resistant Protective Cap, which
can be temporarily left in place until
installation of the ceiling is complete.
