Flood Sensor Activation

  • An add-on connection kit is required to activate the flood sensor's alert features. Without this kit, the flood sensor is a passive component and will not communicate with other devices.
  • Connection kit options include BMS, cellular communication, or the Sensor Control Monitor.
  • The Sensor Control Monitor enables integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi.
  • For existing installations, a retrofit sensor connection kit is also available.

Installation

  • This assembly is approved for horizontal N pattern installation. Groove fittings are provided for integral pipeline adjustment and ease of installation.

Additional Details

This Colt Series C500 2 1/2 inch Reduced Pressure Detector Assembly with a flood sensor is designed to prevent the reverse flow of non-potable water into the potable water supply due to backsiphonage and backpressure, commonly used in fire protection systems.

It also monitors for unauthorized water use and detects excessive discharge from the relief valve, providing alerts when paired with an add-on connection kit.

Features

  • Backflow Prevention: Protects drinking water supplies from health hazards in non-potable service applications such as irrigation, fire line, or industrial processing.
  • Flood Sensor with SentryPlus Alert: Detects excessive water discharges from the relief valve and can relay signals for potential flooding events when an add-on connection kit is used.
  • Unauthorized Water Use Detection: Furnished with a cubic feet meter to detect underground leaks or unauthorized water use from the fire protection system.
  • Robust Construction: The entire valve body and closure sleeve are manufactured from 304 (Schedule 40) stainless steel, offering durability and corrosion resistance.
  • Efficient Design: Extremely compact, 70% lighter than traditional designs, featuring a patented link check for lowest pressure loss.
  • Ease of Service: Unmatched ease of serviceability with replaceable check disc rubber.
  • Installation: Approved for horizontal N pattern installation, featuring groove fittings for integral pipeline adjustment and easy installation.
  • Shutoff Valves: Includes Outside Stem and Yoke (OSY) resilient seated gate valves.

A WARNING: It is illegal to use this product in a plumbing system providing water for human consumption, such as drinking or dishwashing, in the United States. Before installing, consult your local water authority, building, and plumbing codes.
