Description

The Colt LFC500 8 inch Lead Free Reduced Pressure Detector Assembly protects potable water systems from contamination by preventing backflow, backsiphonage, and backpressure. This compact, 70% lighter assembly features a durable Type 304 stainless steel housing, domestic OS&Y resilient seated gate valves with supervisory switches, and grooved fittings. It includes a SentryPlus Alert® flood sensor on the relief valve to detect excessive water discharge, notifying personnel when paired with an-add on connection kit. A metered bypass also monitors for system leaks and unauthorized water usage. Rated for 175 psi, it is ideal for fire sprinkler systems and other health-hazard cross-connections.

Connections

This 8 inch reduced pressure detector assembly features grooved fittings designed for integral pipeline adjustment, ensuring a secure and flexible connection within your system.

Compatibility

  • The assembly is designed for horizontal installation within fire protection systems.
  • The integrated flood sensor with SentryPlus Alert® technology requires an add-on sensor connection kit for activation and communication with monitoring systems. Connection kit options include BMS, cellular communication, or the Sensor Control Monitor for integration with building automation systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi.
  • The domestic outside stem and yoke (OS&Y) resilient seated gate valves include an integrated supervisory switch for system monitoring.

Additional Details

The Colt™ LFC500 Lead Free Reduced Pressure Detector Assembly is designed to protect potable water systems from contamination due to backsiphonage and backpressure.

This 8 inch backflow preventer assembly is ideal for safeguarding against health hazards at cross-connections, such as those found in fire sprinkler systems and service line entrances, while also monitoring for unauthorized water use.

Key Features

  • Features an extremely compact design and is 70% lighter than traditional backflow assemblies.
  • Constructed with a Type 304 (Schedule 40) stainless steel housing and sleeve for durability.
  • Includes domestic outside stem and yoke (OS&Y) resilient seated gate valves and a corrosive-resistant bottom-mounted pressure relief valve.
  • Equipped with groove fittings for integral pipeline adjustment and a patented link check designed for lowest pressure loss.
  • Features a metered bypass (cubic feet per minute meter) to detect underground leaks and unauthorized water usage from the fire sprinkler system.
  • Includes a flood sensor with SentryPlus Alert® technology on the relief valve to detect excessive water discharges.
  • The flood sensor, when paired with an add-on connection kit, relays signals for potential flooding events via multichannel alerts (call, email, text) to notify personnel.
  • Integration options for the flood sensor include BMS, cellular communication, or the Sensor Control Monitor for BAS integration via RS-485 Modbus or Nexa® platform via Wi-Fi.
  • Designed for unmatched ease of serviceability with replaceable check disc rubber and requiring no special tools for maintenance.
  • This OS&Y model includes an integrated supervisory switch on each gate valve.

An add-on connection kit is required to activate the flood sensor; without it, the flood sensor acts as a passive component and will not communicate with any other device. 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 the Colt LFC500 backflow preventer?

Its primary purpose is to protect potable water systems from contamination by preventing the reverse flow of non-potable substances due to backsiphonage and backpressure, commonly used in health-hazard applications like fire sprinkler systems.

What does "Lead Free" mean for this product?

"Lead Free" means that the wetted surface of this product, which comes into contact with consumable water, contains less than 0.25% of lead by weight, complying with national plumbing codes.

How does the integrated flood sensor work, and what is needed to activate it?

The integrated SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate the sensor and enable alert notifications, an add-on sensor connection kit is required; without it, the sensor is passive.

What is the maximum operating pressure and temperature range 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 to 43°C).

What material is used for the housing and sleeve of the LFC500?

The housing and sleeve of the LFC500 assembly are constructed from durable Type 304 (Schedule 40) stainless steel.
