Sensor Connectivity & Monitoring

  • The integrated SentryPlus Alert flood sensor requires an add-on connection kit to become active and relay alerts.
  • Connection kit options include direct communication with a Building Management System (BMS) or via cellular communication.
  • For advanced integration, the Sensor Control Monitor enables connectivity to a BMS via RS-485 Modbus or to the Nexa platform through Wi-Fi.
  • Retrofit sensor connection kits are also available for existing installations.

Additional Details

The 10 inch Lead Free MasterSeries N-pattern reduced pressure detector backflow preventer assembly protects water services from high hazard (toxic) fluids in industrial installations and applications. This assembly features an integrated flood sensor with SentryPlus Alert technology for enhanced monitoring.

Construction & Durability

  • Features a robust ductile iron body for main and relief valve components.
  • The ductile iron body is fused with a patented 3-part ArmorTek epoxy coating, designed to limit microbial induced corrosion (MIC) and protect against exposed metal substrate corrosion.
  • Equipped with stainless-steel relief valve seat and stainless-steel check components for maximum performance, greater dependability, and extended valve life.
  • Includes OSY resilient wedge gate valves for reliable shutoff.
  • Clapper check modules are field serviceable for easy maintenance.

Integrated Flood Sensor

  • Incorporates a SentryPlus Alert flood sensor to detect continuous or excessive water discharges from the relief valve.
  • The flood sensor provides a signal that triggers a multichannel alert (call, email, text) to notify personnel about potential flooding.
  • An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is an isolated component and does not communicate with any other device. A retrofitted sensor connection kit is also available for existing installations.

Bypass Assembly

  • Includes a detector bypass assembly less meter.
  • Auxiliary bypass features include test cocks that remain within the main valve assembly profile, an inline serviceable 3/4" check assembly, field replaceable seat and disc, and capabilities to detect potential underground water leaks or unauthorized water usage.

FAQs

What type of hazards does this backflow preventer protect against?

This 10 inch backflow preventer assembly is designed to protect water services against high hazard (toxic) fluids in industrial installations and applications.

What is ArmorTek coating and what are its benefits?

ArmorTek is a patented 3-part advanced epoxy coating system applied to the ductile iron body. It is designed to limit microbial induced corrosion (MIC) and protect against exposed metal substrate corrosion, extending the assembly's durability and lifespan.

How does the SentryPlus Alert flood sensor work?

The SentryPlus Alert flood sensor detects continuous or excessive water discharges from the relief valve. It provides a signal that can trigger alerts via call, email, or text to notify personnel of potential flooding, requiring an add-on connection kit to activate.

What are the shutoff valve components included with this assembly?

This assembly comes with OSY (Outside Stem & Yoke) resilient wedge gate valves, which are UL Classified and FM Approved for reliable shutoff.

What are the working pressure and temperature limits for this device?

The maximum working pressure for this backflow preventer is 175 psi, with a minimum working pressure of 20 psi. It is designed for continuous operation within a temperature range of 33°F to 140°F (0.5°C to 60°C).
