Product Description
Model F3QR56 Dry sprinklers are quick-response, standard
coverage sprinklers with a nominal K-Factor of 5.6 (80 metric).
Available in Dry Pendent, Dry Horizontal Sidewall, and Dry Up-
right congurations, Model F3QR56 Dry sprinklers all use a 3
mm glass bulb operating element. See the Temperature Rat-
ings table in this Bulletin for available temperature ratings. Mod-
el F3QR56 Dry sprinklers are intended for installation on wet-
pipe, dry-pipe, or preaction sprinkler systems in accordance
with NFPA 13, FM Property Loss Prevention Data Sheets, and
other applicable installation standards.
Model F3QR56 Dry Pendent and Sidewall sprinklers are avail-
able with a variety of escutcheon options as illustrated in Figs.
1 through 3 and Figs. 5 through 9. In addition, Model F3QR56
Dry Pendent sprinklers are also available with the Model CCP
conical concealed cover plate as illustrated in Fig. 4. Available
sprinkler, escutcheon, and cover plate nishes are identied in
the Finishes table in this Bulletin. The Model F1 escutcheon,
Model FP escutcheon, and Model CCP cover plate are the only
recessed escutcheons and cover plate listed for use with Model
F3QR56 Dry sprinklers; the use of any other recessed escutch-
eon or cover plate with Model F3QR56 Dry sprinklers will void
all guarantees, warranties, listings and approvals.
