BACnet Snow/Ice Sensor Interface

The BACnet Snow/Ice Sensor Interface 681 is designed to measure the presence of snow/ice and interfaces with the Building Automation System (BAS) to operate electric or hydronic snow melting systems. The 681 uses tekmar® sensor technology to automatically detect snow or ice, and upon detection communicates with the BAS through BACnet MS/TP. This operation allows the BAS to automatically turn on/off and provide operational status for a snow melting system. The 681 is suitable for any snow melting commercial application including, hospitals, schools, airports, ski resorts, business entrances, driveways, loading docks, and shopping malls.
