Connections & Compatibility

The 2 1/2 inch FEBCO MasterSeries LF866 Reduced Pressure Zone Detector Assembly is designed for horizontal installation in potable water supply lines for high hazard/toxic applications. It features flanged end connections compliant to ASME B16.1 Class 125 and AWWA Class D, ready for integration into corresponding piping systems. Inlet and outlet are equipped with OS&Y resilient wedge gate valves. A 3/4 inch bypass line is included for detecting leaks and unauthorized water usage. The integrated flood sensor requires an add-on connection kit (such as BMS, cellular communication, or a Sensor Control Monitor) to activate its alert functions for remote notification.

Additional Details

The FEBCO MasterSeries LF866 Reduced Pressure Zone Detector Assembly is a 2 1/2 inch lead free backflow preventer designed to protect potable drinking water systems from backpressure and backsiphonage in high hazard/toxic applications. It features an integrated flood sensor to detect excessive water discharges.

Key Features

  • Lead Free construction complies with low lead installation requirements for potable water systems.
  • ArmorTek® Coating: A patented three-part advanced epoxy system applied to internal and external ductile iron components reduces microbial-induced corrosion (MIC) and protects exposed metal substrates.
  • Flood Sensor: Detects excessive water discharges from the relief valve using SentryPlus Alert® technology. An add-on connection kit (BMS, cellular, or Sensor Control Monitor with RS-485 Modbus/Nexa Wi-Fi) is required to activate alerts for potential flooding events.
  • Main Valve: Features stainless steel relief valve seat and check components for maximum performance and durability, field replaceable seats, and reversible/replaceable discs.
  • Auxiliary Bypass: Compact design with an inline serviceable 3/4 inch check assembly to detect potential underground water leaks and unauthorized water usage.

Connections

  • Fitted with UL Classified and FM Approved OS&Y resilient wedge gate valves at inlet and outlet.
  • Four (4) properly located resilient seated test cocks are included for maintenance and testing.
  • End connections compliant to ASME B16.1 Class 125 and AWWA Class D Flange.

Installation must comply with all required instructions, codes, and regulations. An add-on connection kit is required to activate the flood sensor's alert functionality. Without this kit, the sensor operates passively.

FAQs

What type of protection does the FEBCO LF866 provide?

The FEBCO LF866 provides protection against both backpressure and backsiphonage conditions in potable drinking water systems, specifically for high hazard/toxic applications.

Is this backflow preventer assembly lead-free?

Yes, the FEBCO LF866 is designed with lead-free construction, meaning the wetted surface contains less than 0.25% lead by weight, complying with low lead installation requirements.

How does the ArmorTek® coating benefit this assembly?

The ArmorTek® coating is a patented three-part advanced epoxy system applied to the ductile iron components to reduce microbial-induced corrosion (MIC) and protect against corrosion of exposed metal substrates, enhancing the assembly's durability and lifespan.

What is the purpose of the integrated flood sensor?

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. An add-on connection kit is required to activate its alert functionality for remote notification of potential flooding.
