Alpha Open Air

A good many open air festivals have fallen flat due to bad weather. Bad weather, however, is no problem for the rugged and weather-proof telephone alpha® open air®.
The alpha® open air® is definitely the right choice for multistorey car parks, cab stands, open-air storage places,
self-service areas of banks, sports grounds and many other unsupervised or even open-air places.
Mounted on a wall or a mast, in all weathers, rain or shine – telephoning is always possible.
