Fire Department Connection (FDC) Brecco 4" x 2.5" x 2.5" Brass Connection for Fire Sprinkler Systems

The Brecco 4" x 2.5" x 2.5" Siamese Fire Department Connection (FDC) serves as an essential interface for commercial and industrial fire protection assemblies, providing emergency responders a reliable external point to augment water supply in fire sprinkler and standpipe systems. Designed for exposed exterior mounting, this fitting allows fire department pumpers to deliver supplemental water volume and pressure directly into the building infrastructure during critical fire events.

This FDC complies with NFPA 13 standards for sprinkler systems and NFPA 14 standards for standpipe systems, satisfying code requirements for auxiliary water supply connections. The built-in double clapper check valve design prevents reverse flow and maintains internal system pressure, even when only a single hose line is active.

Key Features & Construction

• Solid Brass Construction: Manufactured from high-quality solid brass to provide long-term corrosion resistance in harsh, exposed outdoor environments.
• Siamese Inlet Design: Features dual 2-1/2 inch inlets allowing multiple fire hoses to connect simultaneously for maximum water delivery.
• Secure Outlet: Includes a 4-inch Female National Pipe Taper (FNPT) outlet that creates a pressure-resistant, leak-tight seal with internal building piping.
• Double Clapper Functionality: Incorporates internal clappers to stop backflow and secure system pressure when single or dual lines are engaged.
• Exposed Wall Mount: Engineered for highly visible exterior wall installations to guarantee rapid access for emergency personnel.

Technical Specifications & Compliance Table

Contractors must verify specific Authority Having Jurisdiction (AHJ) mounting height, signage, and thread-type requirements prior to installation. Always consult the manufacturer's engineering guidelines for proper torque and sealing procedures.
