General / Application

Thank you very much for choosing VARIODYN
An emergency audio warning system or a voice alarm system as defined by the standards DIN VDE 0833-4 and
TRVB S 158 must consist of components that satisfy the standards of the series DIN EN 54. It must be ensured
that these components interact together in a manner appropriate to the function.
Devices for use in demanding ambient conditions, such as cold stores, galvanising plants or corrosive
atmospheres, must be suitable for this particular application or must be adapted using suitable protective
measures.

Designation of the system depending on the region of use

Depending on the location of use (country, applicable standard), the system is designated as either an
emergency audio warning system (AWS) or a voice alarm system (VAS).
In the interests of readability, only the term "voice alarm system" is used in the following chapters.

Voice alarm systems (VAS)
A Emergency audio warning system (AWS)
A voice alarm system can be used for issuing alarms anywhere that hazards to people can be expected. Voice
alarms are particularly effective in buildings and rooms frequented by visitors or other people who are not
trained how to act in an emergency or where visual signal devices cannot always be clearly recognised. An
especially high level of risk exists in the case of people who are dependent on external help in an emergency,
such when evacuation of the building is necessary. This may include people who are ill, the elderly and children.
The voice alarm system is mainly used in combination with a fire alarm control panel for emitting alarms. In
practice, the voice alarm system is also used for tasks outside of this area of application. Typical examples of
this include spoken messages such as advertising or calling people in airports, announcements at train stations
or playing background music.
Different requirements are placed on the voice alarm system depending on this combined use as an alarm and
as a general public address system. For example, external loudspeakers which can generate a high volume
level are required for voice alarms. At the same time, however, it should be possible to transmit a high-quality
music signal in other areas and ideally also to control the volume for individual areas. The requirements for the
areas of safety, comfort and flexibility demand a high level of specialised skill for the planning and
implementation of a system as well as very good knowledge of individual product components.

The VARIODYN D1 system is assembled at the factory as a modularly expandable version with various
components according to the specific building requirements. This means that special solutions can be
implemented economically and effectively for buildings of different sizes and for various alarm tasks.
