The VARIODYN ONE is a voice alarm system for buildings. The voice alarm system is used to inform people via loudspeakers – in everyday situations (e.g. announcements) and in emergencies (e.g. evacuation instructions in the event of a fire). It is used in large, publicly accessible buildings (e.g. shopping centres, schools, hotels, so-called “projects”). It is only sold to specialist installers and distributors, not to private households.
