Description

The 2 1/2 inch FEBCO MasterSeries LF860 Reduced Pressure Zone Backflow Preventer assembly is engineered to protect potable water systems from high hazard backpressure and backsiphonage contamination. This lead-free device features a durable ductile iron body with a patented ArmorTek® epoxy coating for superior corrosion resistance, including protection against microbial-induced corrosion. It incorporates stainless steel relief valve seats and check components for long-lasting performance. An integrated SentryPlus Alert® flood sensor detects relief valve discharge, signaling potential flooding events when an optional connection kit is installed, providing crucial maintenance alerts for industrial and commercial applications. Item number F122926.

Flood Sensor Connectivity

  • The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve.
  • To activate the sensor and enable alert notifications, an add-on connection kit is required.
  • Available connection kit options include integration with Building Management Systems (BMS), cellular network communication, or the Sensor Control Monitor which allows for BAS integration via RS-485 Modbus or the Nexa® platform over Wi-Fi.
  • Without a connection kit, the flood sensor functions as a passive component and does not communicate alerts.

Additional Details

This 2 1/2 inch Lead Free FEBCO MasterSeries LF860 Reduced Pressure Zone assembly is designed to protect potable drinking water systems from backpressure and backsiphonage conditions where high hazard (toxic) fluids are present.

It is primarily used in industrial installations and applications where local governing codes mandate protection from non-potable water.

Advanced Protection & Durability

  • Features Lead Free construction with wetted surfaces containing less than 0.25% lead by weight, complying with low lead installation requirements.
  • Equipped with ArmorTek® coating, a patented three-part advanced epoxy system, applied to internal and external ductile iron surfaces to resist microbial-induced corrosion (MIC) and protect exposed metal.
  • Utilizes a stainless steel relief valve seat and stainless steel check components for maximum performance and extended durability.
  • Designed for inline serviceability without requiring special tools, simplifying maintenance.

Flood Detection with SentryPlus Alert® Technology

  • Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • The flood sensor relays a signal to trigger multichannel alerts (call, email, text) about potential flooding.
  • An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component that does not communicate with any other device. Connection kit options include Building Management Systems (BMS), cellular communication, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform via Wi-Fi.

FAQs

What is the primary purpose of the FEBCO MasterSeries LF860 backflow preventer?

The primary purpose of this 2 1/2 inch Lead Free Reduced Pressure Zone assembly is to protect potable drinking water systems from contamination due to backpressure and backsiphonage of high hazard (toxic) fluids. It ensures compliance with local water utility codes for industrial applications.

Is this backflow preventer suitable for use with potable water?

Yes, this assembly features Lead Free construction, meaning its wetted surfaces contain less than 0.25% lead by weight. It is designed for use on potable drinking water systems where protection from non-potable water is mandated.

What is ArmorTek® coating, and what benefits does it offer?

ArmorTek® is a patented three-part advanced epoxy system applied to the internal and external ductile iron components. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates, enhancing the longevity and reliability of the backflow preventer.

How does the flood sensor feature work, and what is needed to activate it?

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate the sensor and enable multichannel alerts (call, email, text), an add-on connection kit is required. Options include BMS, cellular communication, or the Sensor Control Monitor.

What are the maximum operating pressure and temperature limits for this device?

The FEBCO MasterSeries LF860 has a maximum working pressure of 175 psi (12.1 bar) and can operate continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C).
