Product Description
Reliable Models GFR and GFR Recessed Sprinklers are
Quick Response fusible solder type automatic sprinklers.
These sprinklers have demonstrated response times in
laboratory tests which are five times faster than standard
response sprinklers.
This quick response enables the Models GFR and GFR
Recessed Sprinklers to apply water to a fire much faster
than standard response sprinklers of the same temperature
rating.
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 spacing are in accordance with the latest
published standards of the National Fire Protection Associ-
ation or the approving Authority Having Jurisdiction. Quick
response sprinklers are intended for standard area cover-
age and standard water densities as specified in NFPA 13.
Quick response sprinklers and standard response sprin-
klers should not be intermixed.
