Description

This 10 inch Ames Fire & Waterworks 4000SS reduced pressure zone backflow preventer assembly protects potable water supplies from health hazard cross-connections. It prevents reverse flow of contaminated non-potable water due to backsiphonage and backpressure. Featuring a lightweight 300 Series stainless steel body, domestic non-rising stem (NRS) gate valves, and cam-check valves, this assembly offers durability and easy installation. It includes a SentryPlus Alert flood sensor to detect excessive relief valve discharge, relaying alerts with an optional connection kit for BMS, cellular, or Wi-Fi integration. Designed for maximum flow at low pressure drop, it supports a maximum working pressure of 175 psi and a temperature range of 33-110°F.

Flood Sensor Connectivity

  • An add-on connection kit is required to activate the flood sensor. Without this kit, the flood sensor functions as a passive component with no communication capabilities.
  • Compatible connection kit options include BMS (Building Management System), cellular communication, and 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.

Additional Details

This 10 inch stainless steel reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of contaminated water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and/or backpressure. It is ideal for protection at cross-connections identified as health hazard applications and from other contaminants found at the service line entrance.

Product Overview

  • Compact and short lay length design with a single access cover.
  • Features a lightweight stainless steel body for corrosion resistance and maximum strength.
  • Includes domestic non-rising stem resilient seated gate valves, spring loaded cam-check valves, a pressure differential relief valve, and test cocks.
  • The 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 are required for servicing.
  • Compact construction allows for smaller enclosures.
  • The stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs.

Flood Sensor Technology

  • Contains a flood sensor with SentryPlus Alert technology to detect excessive water discharges from the relief valve.
  • When paired with an add-on connection kit, the sensor is activated to relay alerts for potential flooding events.
  • Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS-485 Modbus or the Nexa platform through Wi-Fi.

It is important to thoroughly read all installation instructions and product safety information before beginning the installation of this product. 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.
