Product Description
Reliable Models F1FR56 QREC and F1FR56 QREC
Recessed Sprinklers are quick response sprinklers which
combine the durability for a standard sprinkler with the
attractive 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 faster than standard response sprinklers of the same
temperature rating.

installed into the sprinkler fitting using the Model GFR2
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 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 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
precisely manufactured glass capsule. This glass bulb is
specially constructed to provide fast thermal response.
