FEBCO Series 860 Small reduced pressure zone assemblies feature a flood sensor with SentryPlus Alert® Technology to detect excessive water discharge from the relief valve. Activated through an add-on connection kit, the sensor also triggers the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication. 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 non-potable service applications such as irrigation, fire line, or industrial processing.
