Quick Response Sprinkler
Product Description
Reliable Model KFR56 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 automatic sprinklers utilize a soldered link and
have demonstrated response times in laboratory tests
which are five to ten times faster than standard response
sprinklers. This quick response enables these sprinklers
to apply water to a fire much faster than standard sprin-
klers of the same temperature rating.
The temperature rating of the sprinkler is identified by
marking on deflector: for visual temperature identifica-
tion, the 212°F soldered links are factory marked with
green stripe as shown in Figure 1.
Application
Quick response sprinklers are used in fixed fire protec-
tion systems: Wet, Dry 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 As-
sociation or the approving Authority Having Jurisdiction
(AHJ). Models KFR56 sprinklers are intended for instal-
lation as specified in NFPA 13 in both light and ordinary
Hazard applications. Quick response sprinklers and
standard response sprinklers should not be intermixed.
