This Colt 3 inch lead free reduced pressure zone backflow preventer assembly prevents the reverse flow of fire protection substances and non-potable water from entering the potable water supply due to backsiphonage or backpressure. It is approved for horizontal Z pattern installation in health hazard applications and continuous pressure piping applications.

Flood Detection & Alerting

• Features a flood sensor with SentryPlus Alert® technology to detect continuous discharge from the relief valve.
• An add-on sensor connection kit is required to activate the flood sensor and relay alerts; without it, the sensor is passive.
• Connection kit options include BMS, cellular communication, and the Sensor Control Monitor for integration with BAS via RS‑485 Modbus or the Nexa® platform through Wi-Fi.
