Product Description
Reliable Models F1FR QREC and F1FR QREC Recessed
Sprinklers are quick response sprinklers which combine the
durability for a standard sprinkler with the attractive low pro-
file of a decorative sprinkler.
The Models F1FR QREC and F1FR QREC Recessed Auto-
matic 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 standard sprinklers of
the same temperature rating.
The glass bulb consists of an accurately controlled amount
of special fluid hermetically sealed inside a precisely manu-
factured glass capsule. This glass bulb is specially con-
structed to provide fast thermal response. The balance of
parts are made of brass, copper and beryllium nickel.
The temperature rating of the sprinkler is identified by the
color of the glass bulb.
Application
Quick response sprinklers are used in fixed fire protec-
tion systems: Wet, Dry, Deluge or Preaction. Care must be
exercised that the orifice size, temperature rating, deflector
style and sprinkler type are in accordance with the latest
published standards of the National Fire Protection Asso-
ciation or the approving authority having jurisdiction. Quick
response sprinklers are intended for installation as specified
in NFPA 13.
