Flood Sensor Connection & Activation

  • The integrated flood sensor is designed to detect excessive water discharge from the relief valve.
  • To activate the flood sensor and enable alerts, an add-on connection kit is required (sold separately).
  • Without a connection kit, the flood sensor remains a passive component and will not communicate or trigger alerts.
  • Connection kit options include interfaces for Building Management Systems (BMS), cellular communication, or the Sensor Control Monitor.
  • The Sensor Control Monitor allows integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity.

Additional Details

The FEBCO MasterSeries LF886V 10 inch lead free Reduced Pressure Zone Detector Assembly (RPZDA) is designed to protect potable water systems from backpressure and backsiphonage conditions involving high hazard/toxic fluids in industrial and other applications.

This assembly prevents contaminants from entering the potable water supply, meeting local governing water utility codes and standards.

Key Features

  • Designed for high hazard/toxic applications.
  • Includes OSY shutoff valves for reliable isolation.
  • Features a detector bypass assembly with a gallons per minute (GPM) meter to monitor water usage or leaks.
  • Equipped with a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.

Construction & Durability

  • Ductile iron body construction ensures robustness.
  • Patented ArmorTek® 3-part advanced epoxy coating system applied to internal and external surfaces provides integrated protection against electrochemical and microbial-induced corrosion (MIC).
  • Stainless steel relief valve seat and stainless steel check components offer maximum performance, durability, and extended valve life.
  • Inline serviceable assembly means no special tools are required for maintenance of internal components.

Flood Detection & Alerts

  • The integrated flood sensor relays a signal upon detecting continuous discharge from the relief valve.
  • When paired with an add-on connection kit (sold separately), the sensor is activated to trigger multi-channel alerts (call, email, text) to notify personnel about potential flooding.
  • The flood sensor requires an add-on connection kit to be fully functional and communicate alerts. Without it, the sensor is a passive component.

FAQs

What is the primary purpose of the FEBCO MasterSeries LF886V backflow preventer?

Its primary purpose is to protect potable drinking water systems from contamination due to backpressure and backsiphonage, especially in high hazard/toxic fluid applications.

What is ArmorTek coating and what are its benefits?

ArmorTek is a patented three-part advanced epoxy coating system applied to the ductile iron body. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces, extending the life and dependability of the assembly.

How does the flood sensor function on this assembly?

The integrated flood sensor with SentryPlus Alert technology detects excessive water discharges from the relief valve. When an add-on connection kit (sold separately) is installed, the sensor can relay signals to trigger multi-channel alerts (call, email, text) to notify personnel of potential flooding.

What are the main components included in this backflow preventer assembly?

This assembly includes a ductile iron body with ArmorTek coating, UL Classified and FM Approved OSY shutoff valves, replaceable stainless steel check seats, a gallons per minute (GPM) metered bypass assembly, ball valve test cocks, and an integrated flood sensor.

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

The maximum working pressure for this backflow preventer is 175 PSI (12.1 bar). It can operate within a temperature range of 33°F to 140°F (0.5°C to 60°C).
