SentryPlus Alert® flood sensor for flood detection
Ductile iron body with ArmorTek® epoxy coating
Equipped with OSY shutoff valves
Stainless steel relief valve seat and check components
Maximum Working Pressure: 175 PSI
Temperature Range: 33°F - 140°F
Description
This 2 1/2 inch lead free FEBCO MasterSeries LF886V Reduced Pressure Zone Detector Backflow Preventer Assembly is designed for potable water systems, protecting against high hazard fluids due to backpressure and backsiphonage. It features a durable ductile iron body with ArmorTek® 3-part epoxy coating for superior corrosion resistance and OSY shutoff valves. The integrated SentryPlus Alert® flood sensor detects relief valve discharge, requiring an add-on connection kit for activation and alert capabilities. Rated for a maximum working pressure of 175 PSI and temperatures from 33°F to 140°F, it is UL Classified, FM Approved, and ASSE 1047 compliant.

System Integration
To activate the integral flood sensor, an add-on connection kit is required.
Connection kit options allow integration with Building Management Systems (BMS), cellular communication, or the Sensor Control Monitor.
The Sensor Control Monitor enables integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi.
This 2 1/2 inch lead free FEBCO MasterSeries LF886V Reduced Pressure Zone Detector Backflow Preventer Assembly is designed to protect potable water systems against backpressure and backsiphonage conditions for high hazard (toxic) applications in industrial and commercial installations.
Key Features
Features a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
Ductile iron body construction with patented ArmorTek® 3-part advanced epoxy coating system to resist microbial induced corrosion (MIC) and protect exposed metal substrate.
Equipped with OSY shutoff valves, bypass, and ball valve test cocks.
Stainless steel relief valve seat and stainless steel check components ensure maximum performance and durability.
Inline serviceable design allows for maintenance without special tools.
Flood Sensor Activation
An add-on connection kit is required to activate the flood sensor. Without this kit, the sensor is a passive component and does not communicate with other devices.
When activated, the sensor relays a signal for a multichannel alert (call, email, text) to notify personnel about potential flooding.
Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which integrates with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
Auxiliary Bypass
Compact design remains within the main valve assembly profile.
Inline serviceable 3/4 inch check assembly with field replaceable seat and disc.
Helps detect potential underground water leaks and unauthorized water usage.
Important: 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. Always read all installation instructions and product safety information thoroughly before beginning installation. Inquire with governing authorities for local installation requirements.

FAQs
What is the primary use of the FEBCO LF886V backflow preventer?
This 2 1/2 inch lead free MasterSeries LF886V assembly protects potable water systems from high hazard (toxic) fluids caused by backpressure and backsiphonage conditions. It is typically used in industrial and commercial installations.
Is this backflow preventer assembly lead-free?
Yes, the FEBCO MasterSeries LF886V is lead-free. The wetted surface of this product, contacted by consumable water, contains less than 0.25% of lead by weight to comply with low lead installation requirements.
How does the SentryPlus Alert® flood sensor function?
The integral SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. An add-on connection kit is required to activate the sensor, enabling it to relay signals for multichannel alerts, such as calls, emails, or texts, to notify personnel of potential flooding.
What materials are used in the construction of this backflow preventer?
The main and relief valve bodies are constructed from ductile iron Grade 65-45-12, coated with ArmorTek® powder coating for corrosion resistance. Internal components like check seats, relief valve seats, and springs are stainless steel, while the elastomer disc is silicone.
What are the maximum operating pressure and temperature limits?
The FEBCO LF886V backflow preventer 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).
