Flood Sensor Connectivity

  • An add-on connection kit is required to activate the flood sensor's alert capabilities.
  • Without a connection kit, the flood sensor functions as a passive component with no external communication.
  • Compatible connection kit options include: 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.

Physical Connections

  • Flange dimensions are in accordance with AWWA Class D.

Additional Details

This 10 inch Lead Free reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and non-potable water into the potable water supply due to backsiphonage or backpressure.

It is ideal for continuous pressure piping applications and for health-hazard cross-connections, protecting the service line entrance from contaminants. This assembly features a short lay length, lightweight stainless steel body, and includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.

Features

  • Stainless steel construction provides long-term corrosion resistance and maximum strength
  • Stainless steel body is half the weight of competitive designs, reducing installation and shipping costs
  • Short end-to-end dimensions make retrofitting easy
  • Cam-check assembly provides maximum flow at low pressure drop
  • No special tools required for servicing
  • Compact construction allows for smaller enclosures
  • Stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs
  • Flood sensor with SentryPlus Alert® technology for flood detection, relays a signal for notification
  • Flood alert feature activated with an add-on sensor connection kit, compatible with BMS and cellular network communication

An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component that has no communication with any other device. The use of the flood sensor does not replace the need to comply with all required instructions, codes, and regulations related to installation, operation, and maintenance of this product, including the need to provide proper drainage in the event of a discharge.

FAQs

What is the primary purpose of this 10 inch backflow preventer?

This 10 inch Lead Free reduced pressure zone assembly is designed to protect potable water supplies from contamination caused by backpressure or backsiphonage of non-potable water and fire protection substances at health-hazard cross-connections.

Does this backflow preventer include shutoff valves?

No, this specific model (4000SS-LG-FS) is supplied "Less Gates" (LG), meaning it does not include shutoff valves.

How does the flood sensor feature work?

The integrated SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. When paired with an optional add-on connection kit, it can relay alerts to facility personnel via BMS, cellular communication, or Wi-Fi through the Sensor Control Monitor.

What materials are used in the construction of this backflow preventer?

The main valve body and internal metal parts are constructed from 300 Series stainless steel for corrosion resistance. The check assembly uses Noryl® material. It is also Lead Free, containing less than 0.25% lead by weight.

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

This backflow preventer has a maximum working pressure of 175 psi (12.1 bar) and can operate within a temperature range of 33°F to 110°F (0.5°C – 43°C).
