3 Function

Intended use

- Detection of water penetration and leaks

- Connection to KNX pushbutton interfaces or similar binary inputs

- Fitting to the surface to be monitored

Function of the leakage sensor

The device monitors the electrical conductivity between the conductive coatings on the sensor
surface. If it is dampened with water, the device detects the change and signals it.

i The device cannot prevent water from leaking, but detects and registers it early, so that the

impact of water damage can be kept minor.

i The sensor surface can be damaged if it comes into contact with aggressive media (e.g.

detergent solutions, scrubbing brines or acidic condensation from condensing boilers).
Check the sensor area (3) after every alarm. In case of significant damage from corrosion
replace the device.
