IWU - Indoor Warning Unit

In certain conditions, such as e.g. high noise levels of machines or due to sound insulation measures in the building, it is possible that alarm signals cannot be heard inside buildings or are hard to hear.

In this case, Hörmann supplies special IWU systems for alarms inside buildings.
The IWU is based on the electronic siren technology and can therefore be easily combined with ECN sirens in a comprehensive warning system.
