This Colt™ 2 1/2 inch Lead Free Reduced Pressure Detector Backflow Preventer Assembly provides critical protection to potable water systems by preventing contamination from backsiphonage and backpressure, while also monitoring for unauthorized water use from fire protection systems. Its compact, modular design features Type 304 stainless steel construction and is approved for horizontal Z pattern installation.

Flood Detection & Monitoring

• Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
• An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component and will not communicate with any other device.
• When paired with an add-on connection kit, the sensor relays alerts for potential flooding events via BMS, cellular communication, or the Sensor Control Monitor, enabling integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Construction & Design

• The entire valve body and closure sleeve are manufactured from Type 304 (Schedule 40) stainless steel.
• Features grooved gear operated butterfly valves with tamper switch.
• Incorporates two independent Link Check modules with reversible elastomer discs for drip-tight closure against reverse flow.
• Includes a bottom-mounted cast stainless steel relief valve and nickel-plated Lead Free bronze body test cocks.
• Designed for extremely compact installation and is approximately 70% lighter than traditional designs.

Performance & Functionality

• A metered bypass with a CFM meter helps detect underground leaks and unauthorized water use from the fire sprinkler system.
• Patented link check design for lowest pressure loss and unmatched ease of serviceability.
• Replaceable check disc rubber for easy maintenance.
