Product Description
Reliable Models F1FR56 QREC and F1FR56 QREC Re-
cessed Sprinklers are quick response sprinklers which
combine the durability for a standard sprinkler with the at-
tractive low profile of a decorative sprinkler.
The Models F1FR56 QREC and F1FR56 QREC Recessed
Automatic Sprinklers utilize a 3.0mm frangible glass bulb.
These sprinklers have demonstrated response times in
laboratory tests which are five times faster than standard
response sprinklers. This quick response enables these
sprinklers to apply water to a fire much faster than stan-
dard sprinklers of the same temperature rating.
Model F1FR56 QREC Quick Response Extended Cover-
age Concealed Sprinkler is an attractive, low profile con-
cealed sprinkler assembly. This sprinkler assembly uti-
lizes a Model F1FR56 QREC pendent sprinkler in a Model
CCP cup and push-on thread-off cover plate assembly.
The cup is securely factory threaded on the sprinkler’s in-
let end. The assembly is shipped with a protective cap.
The sprinkler and cup are easily installed into the sprinkler
fitting using the Model RC1 Sprinkler Wrench. The cover
plate assembly is attached to the sprinkler cup using a
flexible tooth threaded engagement. The cover plate is
attached to the skirt using 135°F (57°C) ordinary tempera-
ture classification solder.

When the ceiling temperature rises, the solder holding
the cover plate melts, allowing the release of this part and
thus exposing the Model F1FR56 QREC sprinkler inside to
the rising ambient temperature.
The Temperature rating of the sprinkler identified by the
color of the glass bulb.
The glass bulb consists of an accurately controlled
amount of special fluid hermetically sealed inside a pre-
cisely manufactured glass capsule. This glass bulb is spe-
cially constructed to provide fast thermal response.
Application
Quick response sprinklers are used in fixed fire protection
systems: Wet, Dry, Deluge or Preaction. Care must be exer-
cised that the orifice size, temperature rating, deflector style
and sprinkler type are in accordance with the latest published
standards of the National Fire Protection Association or the ap-
proving authority having jurisdiction. Quick response sprinklers
are intended for installation as specified in NFPA 13.
