Mobile warning and communication system

/// Warning and communicating in an emergency

In hazardous and large-scale operations as well as in catastrophe scenarios, gaps in the warning and information provision of the affected population have recently become apparent.

If there are power, mobile phone and data network failures or if an area is completely cut off from the warning network, it is hardly possible to warn and inform the inhabitants of the affected areas.

This is compounded by the uncertainty of a broad section of the population as to how they should behave or prepare themselves in immediate danger situations.

The MOWACOM can provide a remedy:

Warning: attracting attention (location-independent and mobile) through various warning tones

Communication: in addition to public media, information locally & temporally flexible


The mobile warning and communication system (MOWACOM) has been specially developed for users in professional use. It is designed to be easily transported, set up and operated by one person. The system is powered by the cigarette lighter, so it can be used without a power supply and also in private vehicles. The components, which have proven themselves in special applications, are integrated in the stackable protective case.

The basic version includes a roof unit, a handset with integrated microphone for voice announcements and an amplifier with jack plug interface. The package can be expanded to include a digital recording/playback device with interfaces for additional external audio sources (USB stick, MP3 player, mobile phone audio, etc.) as well as a beacon.
