Assembly Components

  • This reduced pressure zone backflow preventer assembly features domestic non-rising stem shutoff valves for isolation, test cocks for verification, spring loaded check valves, and a pressure differential relief valve for protection against backpressure and back-siphonage.

SentryPlus Alert® Flood Sensor Connectivity

  • The integrated SentryPlus Alert® flood sensor detects continuous discharge from the relief valve. For remote monitoring and alerts, it can be paired with an add-on connection kit (sold separately).
  • Connection kit options include those for BMS (Building Management Systems), cellular communication, or the Sensor Control Monitor.
  • The Sensor Control Monitor enables integration with BAS (Building Automation Systems) via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity.

FAQs

What does this backflow preventer protect against?

This 2 1/2 inch FEBCO LF880V-DNRS-FS assembly is designed to protect water services against backflow from high hazard (toxic) fluids in industrial and commercial installations.

What is the body material and coating of this assembly?

The body is constructed from ductile iron and features a patented 3-part ArmorTek® advanced epoxy coating system. This coating is designed to resist microbial induced (MIC) and exposed metal substrate corrosion, ensuring long-term durability.

Does this backflow preventer have flood detection capabilities?

Yes, it includes SentryPlus Alert® technology with a flood sensor to detect continuous discharge from the relief valve. This helps prevent potential flooding and allows for alert integration with optional connection kits.

How can the flood sensor be integrated for remote alerts?

When paired with an add-on connection kit (sold separately), the flood sensor can integrate with Building Management Systems (BMS), cellular communication, or a Sensor Control Monitor. The Sensor Control Monitor enables connection to BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

What type of shutoff valves are included with this assembly?
