Combustible Concealed Space Sprinkler

The Reliable Model KFR-CCS Sprinkler is designed to protect specific light hazard combustible and noncombustible concealed spaces requiring sprinkler protection. Its high, flat spray pattern provides ideal coverage of these spaces, and its rugged 212°F fusible link design requires no bulb protector. The KFR-CCS is suitable for installation with CPVC pipe (wet systems) or steel pipe (wet, dry, or preaction systems).

The KFR-CCS 56 recently received an enhanced cULus Listing:

  • Protection of concealed spaces with trusses without requiring draft curtains.
  • Protection of concealed spaces with trusses up to 60 inches in height.
  • Maximum sprinkler spacing up to 16 feet in concealed spaces with trusses or non-combustible insulation-filled joists.

Beyond adding the expanded cULus Listing, technical bulletin 044 now makes it easier to understand the proper application of the sprinkler.
