The Plena (VAS) Voice Alarm System range is an ideal evacuation, message and background music solution for small to medium sized applications in a variety of locations, such as schools, hotels, shopping centers, factories, offices and similar applications where public safety is essential.

The system continues the family’s versatile standalone, plug-and-play concept and is easy to set up and control. With release 3.0, Bosch has ensured full compliance with EN54-16 and ISO 7240-16 standards for an extended number of 120 zones.

Based on a Plena voice alarm controller unit, VAS can handle up to 6 zones with a built-in message manager, emergency microphone and a built-in 240 W power amplifier. By connecting additional 6-zone routers to the Plena VAS, the number of zones extends to a 120-zone capacity. The power per zone is freely distributable per zone and it can be over 1000 Watts per router (or 6 zones). In addition, 8 call stations with 32 call station keypads with programmable keys can be interconnected for message routing. Additional PLENA amplifiers can be added to create two-channel systems. The Plena Voice Alarm system is configured via a Windows.
