Flood Sensor Connectivity

The integrated flood sensor requires an add-on connection kit to become active and communicate alerts. Without this kit, the flood sensor acts as a passive component and will not relay signals to external devices. Compatible connection kit options include those for:

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

Valve Operation

This assembly features OSY (Outside Stem and Yoke) resilient seated gate valves. These valves are designed for reliable shutoff and include an option for an integrated supervisory switch.

Additional Details

The Colt 10 inch LFC500 Reduced Pressure Detector Assembly is engineered to safeguard potable water systems from contamination due to backsiphonage and backpressure, making it ideal for health-hazard cross-connections found in fire sprinkler systems.

This Lead Free backflow preventer incorporates an advanced flood sensor with SentryPlus Alert® technology on the relief valve to detect and signal excessive water discharges, providing critical monitoring against unauthorized water use or system leaks.

Features

  • Lead Free* construction meeting installation requirements for potable water applications
  • Extremely compact design, approximately 70% lighter than traditional designs
  • Housing and sleeve constructed from Type 304 (Schedule 40) stainless steel for durability
  • Includes OSY (Outside Stem and Yoke) resilient seated gate valves for reliable shutoff
  • Features link check modules with a patented design for lowest pressure loss
  • Unmatched ease of serviceability with replaceable check disc rubber
  • Bottom-mounted cast stainless steel relief valve
  • Equipped with a metered bypass (gallon per minute meter) to detect underground leaks and unauthorized water usage
  • Integrated flood sensor on the relief valve with SentryPlus Alert® technology for flood detection
  • Capable of relaying alerts for potential flooding events when paired with an add-on sensor connection kit
  • Includes an integrated supervisory switch as an option on each gate valve for the OS&Y model

An add-on connection kit is required to activate the flood sensor for communication; without this kit, the sensor functions as a passive component and will not communicate with other devices. The flood sensor does not replace compliance with drainage and installation codes.

FAQs

What is the primary purpose of the Colt LFC500 Reduced Pressure Detector Assembly?

The primary purpose is to protect potable water systems from contamination due to backsiphonage and backpressure, particularly in health-hazard cross-connections like fire sprinkler systems.

Is this backflow preventer suitable for potable water applications?

Yes, it features Lead Free* construction, making it compliant with requirements for potable water installations.

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

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. An add-on connection kit is required to activate the sensor for communication; otherwise, it remains a passive component.

What materials are used for the main body and internal components?

The housing and sleeve are made from durable Type 304 (Schedule 40) stainless steel. Elastomers include EPDM, silicone, and Buna-N, while link checks are Noryl® and stainless steel, and check discs are reversible silicone or EPDM.

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

This 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 – 43°C).
