Quick Response Sprinkler
Product Description
Reliable Models F1FR Series Sprinklers are quick re-
sponse sprinklers which combine the durability of a stan-
dard sprinkler with the attractive low profile of a decorative
sprinkler.
The Models F1FR Series Recessed automatic sprinklers
utilize a 3.0 mm frangible glass bulb. These sprinklers have
demonstrated response times in laboratory tests which
are five to ten times faster than standard response sprin-
klers. This quick response enables the Model F1FR Series
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.
At normal temperatures, the glass bulb contains the fluid
in both the liquid and vapor phases. The vapor phase can
be seen as a small bubble. As heat is applied, the liquid
expands, forcing the bubble smaller and smaller as the liq-
uid pressure increases. Continued heating forces the liquid
to push out against the bulb, causing the glass to shatter,
opening the waterway and allowing the deflector to distrib-
ute the discharging water.

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, deflec-
tor style and sprinkler type are in accordance with the lat-
est published standards of the National Fire Protection As-
sociation or the approving Authority Having Jurisdiction.
Quick response sprinklers are intended for installation as
specified in NFPA 13. Quick response sprinklers and stan-
dard response sprinklers should not be intermixed.
