Features
- Sensor on the relief valve for flood detection
- Flood alert feature activated with add-on connection kit, compatible with BMS and cellular communication
- Utilizes advanced ArmorTek coating technology to build in electrochemical corrosion inhibitor and microbial inhibitor to resist corrosion of internal parts
- Combines the use of a stainless-steel relief valve seat and stainless-steel check components for maximum performance and durability
- Requires no special tools for inline service
- Is highly suitable for potable drinking water systems where code mandates protection from backpressure and backsiphonage conditions
- Protects potable water against cross-connection contamination of high hazard (toxic) fluids in water services
- Sizes 2 1/2 to 10 Inch
MasterSeries LF866 Lead Free* reduced pressure detector assemblies feature a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.
This series help stop the reverse flow of fire protection system substances being pumped or siphoned into the potable water supply. A meter incorporated to detect ground leaks and unauthorized illegal taps greatly reduces annual water expenses. Check with local water authorities for installation requirements.
