Voice Evacuation System

ESSER was quick to act on the expansion of the classic fields of application in voice alarm systems: With VARIODYN® D1, the new VDS approved product line for trend-setting voice alarm, an extensive product portfolio is available for the most diverse areas of application – from digital communication units and power amplifiers to compact complete systems.

Voice Alarm is increasingly important in the safe management of buildings. A voice message informs occupants exactly what to do in an emergency and it is a long established fact that people respond more quickly and are more likely to take the correct action during an evacuation if voice messages are used instead of tone sounders.
