Flood Sensor Activation

This 4000SS-OSY-FS backflow preventer includes a passive flood sensor. To activate its alert capabilities, an add-on connection kit is required. Connection kit options enable communication with various systems:

  • Building Management Systems (BMS)
  • Cellular network communication
  • Sensor Control Monitor for integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity.

These kits allow the sensor to relay signals to facility personnel for prompt corrective action in the event of excessive water discharge from the relief valve.

Additional Details

This 10 inch Lead Free Reduced Pressure Zone (RPZ) backflow preventer assembly is engineered to safeguard potable water supplies from contamination caused by backsiphonage and backpressure.

It is suitable for health-hazard cross-connections in continuous pressure piping applications, such as fire protection systems and service line entrances, ensuring protection against hazardous materials entering the drinking water.

Key Features

  • Lead Free* construction meets installation requirements for potable water applications.
  • Stainless steel body provides long-term corrosion resistance, maximum strength, and is half the weight of competitive designs, simplifying installation and reducing shipping costs.
  • Short end-to-end dimensions allow for easy retrofitting into existing piping systems.
  • Patented cam-check assembly ensures maximum flow with low pressure drop and requires no special tools for servicing.
  • Compact construction permits installation in smaller enclosures.
  • Stainless steel relief valve with a balanced rolling diaphragm eliminates sliding seals, leading to lower maintenance costs.
  • Integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve.

Flood Detection & Alerting

  • The flood sensor provides passive detection of discharge.
  • An add-on connection kit is required to activate the sensor and enable communication.
  • Activated sensor relays a signal to facility personnel for corrective action, helping to limit flooding and costly damage.
  • Compatible with Building Management Systems (BMS), cellular networks, and the Sensor Control Monitor for integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa platform by Wi-Fi.

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 function of the 10 inch 4000SS-OSY-FS backflow preventer?

Its primary function is to protect potable water supplies from contamination by preventing the reverse flow of hazardous materials due to backsiphonage or backpressure from non-potable sources.

What does "Lead Free" mean for this backflow preventer?

"Lead Free" indicates that the wetted surface of this product, which comes into contact with consumable water, contains less than 0.25% lead by weight, complying with national lead-free installation requirements.

How does the flood sensor work and what is required to activate it?

The integrated flood sensor passively detects excessive water discharge from the relief valve. To activate its alert functionality and enable communication, an add-on connection kit is required, compatible with BMS, cellular networks, or the Sensor Control Monitor.

What is the maximum operating pressure and temperature range for this assembly?

This 10 inch 4000SS-OSY-FS assembly has a maximum working pressure of 175 psi (12.1 bar) and an operating temperature range of 33°F to 110°F (0.5°C to 43°C).

What type of shutoff valves are included with this backflow preventer?

This assembly is equipped with resilient seated Outside Stem and Yoke (OSY) shutoff valves, which are UL Classified and FM Approved.
