The Kentix leakage sensor KLS03 reports its alarm through the digital input on the AlarmManager or MultiSensor.
To fix this, log on to the AlarmManager or MultiSensor and open the Sensors - Devices tab. Select the Dashboard. Navigate to the settings of the leakage sensor or the device to which the leakage sensor is connected.
Then click on Save to confirm and save the configuration changes.
You can now test the leakage sensor with the help of a damp cloth.
