Product Description

Model F1FR QREC Quick Response Extended Coverage
Concealed Sprinkler is an attractive, low profile concealed
sprinkler assembly. This sprinkler assembly utilizes a Model
F1FR 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 inlet end. The assembly is shipped
with a protective cap. The sprinkler and cup are easily installed
into the sprinkler fitting using the Model GFR2 Sprinkler Wrench.
The cover plate assembly is attached to the sprinkler cup us-
ing a flexible tooth threaded engagement. The cover plate is
attached to the skirt using 135°F (57°C) ordinary temperature
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 F1FR QREC sprinkler inside to the rising
ambient temperature. The Temperature rating of the sprinkler
identified by the color of the glass bulb.
Model F1FR QREC automatic sprinkler utilizes a 3.0 mm fran-
gible glass bulb. This sprinkler has demonstrated response
times in laboratory tests which are five times faster than stan-
dard response sprinklers. This quick response enables the
Model F1FR QREC sprinkler to apply water to a fire faster than
standard sprinklers of the same temperature rating.
