How does it detect water leaks and freezing?
When the metal at the bottom of the sensor comes into contact with water, it triggers an alarm to help quickly locate the leak. The built-in temperature sensor will trigger a freezing alarm when the ambient temperature drops below the set threshold.
What is the function of the extension cable?
The extension cable comes with a slim probe that can detect water leaks in narrow gaps. When suspended, it will activate the alarm when the water level reaches a certain point.
