The FloodMaster RS-080 Series of Water Main Shut-Off and Alarm products are designed for localized leak detection (one room, one floor, etc.). When a leak is detected, the unit will automatically shut off the water main supply line. Specific model selection is based on the valve size required to interface to the designated water main pipe. Standard valve sizes range from 3/4″ to 4″ (see full list of sizes below).
For more sophisticated monitoring across larger areas and multiple floors, please see the RS-360 for cutting-edge wireless plumbing leak and frozen pipe protection.
While other FloodMaster leak detection products are intended for localized appliance control, the RS-080 series is designed for the complete shutoff of water to the entire building or facility plumbing section. When the sensor puck comes in contact with water, the system will automatically shut down the water feed line and sound an audible alarm, thus avoiding extensive water damage. FloodMaster units are easy to install and require no electrical wiring. An optional dry contact output to a home security panel, control room or appropriate relay is also standard on all units.
