C400
Stainless Steel Reduced Pressure Zone Assembly Backflow Preventers with Flood Sensor - 2 1/2 - 10 IN Sizes
Features
- Sensor on the relief valve for flood detection
- Protects against backsiphonage, backpressure, and the fouling of either check valve
- Stainless steel body construction, sleeve and torsion spring check valves
- Extremely compact design is significantly lighter than traditional designs
- Patented link check modules provide low pressure loss
- Entire valve body and closure sleeve manufactured from 304 stainless steel
- Flood alert feature activated with add-on connection kit, compatible with BMS and cellular communication
- Integrates with the Sensor Control Monitor to deliver maintenance alerts to BAS via RS-485 Modbus or the Nexa platform by Wi-Fi connectivity
- Integrated supervisory switch (UL Certified, Safety Signaling, Control No. 3L38) on outside stem and yoke resilient seated gate valve
Nexa pairs integrated sensing hardware with free, upgradable software to empower facilities with unprecedented visibility and control over their water systems, helping teams protect assets, deliver consistent performance, and drive measurable ROI.

Series C400 reduced pressure zone assemblies feature a flood sensor using SentryPlus Alert® technology to detect continuous discharge from the relief valve. When paired with an add on connection kit, the sensor is activated to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS‑485 Modbus or the Nexa® platform through Wi-Fi.
This series prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. Ideal for protection at health hazard cross-connections or for containment at the service line entrance. Its compact modular design facilitates maintenance and assembly access. Check with local water authorities for installation requirements.

The TS-OSY model is equipped with a factory installed, durable, and robust supervisory switch (UL Certified, Safety Signaling, Control No. 3L38) for tamper detection. The alert sounds when attempts are made to remove the switch from the gate valve or to close the valve. Wiring of the supervisory switch to a fire alarm control panel is required.
