Connecting the Backflow Preventer

  • This assembly utilizes groove couplings for straightforward installation and integral pipeline adjustment.
  • For flood monitoring, the integrated flood sensor requires an add-on sensor connection kit to be activated and communicate with other devices.
  • Connection kit options include Building Management Systems (BMS), cellular communication, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Additional Details

The Colt C400-OSY-FS 10 inch lead free reduced pressure zone backflow preventer assembly is engineered to prevent the reverse flow of fire protection substances and non-potable water into the potable water supply due to backsiphonage and backpressure.

This assembly is ideal for continuous pressure piping applications and cross-connections identified as health hazards.

Construction & Design

  • Features a Type 304 (Schedule 40) stainless steel housing and sleeve for durability
  • Includes two independent Link Check modules and a bottom-mounted differential pressure relief valve
  • Equipped with drip tight shutoff valves that are resilient seated outside stem and yoke (OS&Y) gate valves
  • Utilizes groove couplings for easy installation and integral pipeline adjustment
  • Lead Free* construction ensures compliance with lead-free installation requirements
  • Extremely compact design, approximately 70% lighter than traditional models, allowing for smaller enclosures
  • Replaceable check disc rubber for extended service life
  • Patented link check design provides lowest pressure loss and unmatched ease of serviceability

Flood Sensor & Alerts

  • Contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve
  • Flood alert feature is activated with an add-on sensor connection kit
  • The OS&Y model includes an option for an integrated supervisory switch on each gate 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.
