Leakage sensor
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.
The device cannot prevent water from leaking, but detects and registers it early, so that
the impact of water damage can be kept minor.
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) every alarm. In case of significant damage from corrosion re-
place the device.
Application examples

– Below or next to the bathtub or shower
– Under the wash basin or behind vanities
In the kitchen area:
– Under the kitchen unit
– Under the dishwasher
– Under the sink
In utility rooms or functional spaces:
– Below or behind washing machines
– In boiler rooms
– In supply shafts with water pipes
– In cellar rooms with a risk of backflow
In living areas:
– Below or behind aquariums
– In the heating manifold of underfloor heating systems
4 Information for electrically skilled persons
4.1 Fitting and electrical connection
Fitting the leakage sensor
Figure3: Appropriate and inappropriate locations for fitting
Do not place the device on sloping surfaces, ridges or pedestals (Figure 3).
Look for an appropriate installation location at which escaping water can be detected early.
￭ Place the device directly on the surface that is to be monitored. The sensor surface (3)
must point downwards.
￭ Mount the device on the supporting surface, e.g. with a screw assembly, torque
max. 0.4 Nm
The vent opening (4) may not be used to mount the device.
For proper function, liquid must be able to reach the sensor surface (3).

Leakage sensor
Do not mount the device to the substrate with sealing compound (silicone, acrylic or sim-
ilar).
￭ Fit the connecting cable, e.g. with nail clamps.
The vent opening (4) supports the sensor function and should be free of dirt.
Figure4
Connecting the leakage sensor
The device is directly connected to an evaluation unit and supplied by it. The signaling takes
place by short-circuiting the supply voltage.
Figure5
￭ Connect the device to an evaluation unit (6) that supplies and monitors the device.
￭ Observe the polarity:
White = +
Brown = – / COM
