The warning and switch units can be used for a wide range of purposes e.g. as warning devices in the household and in industrial systems as well as for connection to a remote signal sensor which then transmits the acoustic signal to other rooms or to a central warning system. The warning units are used to monitor and report flooding caused by defective pipes, cellar drains or backwater valves.

The warning and switch units with potential-free contact can be connected to the central guidance system (ZLT). The electronic sensors react to all conductive fluids and the optical sensors to all conductive and non-conductive fluids. All units are complete with all the necessary installation elements and easy to install.
