What is the Extension Cable and what should I use it for?

The Extension Cable is just that – a cable that has been included to extend the reach of the Rope Sensor. The Extension Cable does not sense water so it can be used along walls or under cabinets where leak detection isn’t needed. Let’s say you mount your SensXtend Sensor Dock on the wall next to your refrigerator. You can use the Extension Cable along the wall so you can maximize the leak detection of the entire Rope Sensor under the refrigerator.
