TÜV conducted tests of the Plena Voice Alarm System independently according to standard EN/IEC 60849, "Sound Systems for Emergency Purposes". This standard is applied for hotels, schools, entertainment venues, sports facilities, railroad
stations, department stores, exhibition halls and similar buildings. The issue of TÜV certification in this rigorous test confirms that Bosch Security Systems has satisfied exceptionally stringent requirements in its development of public address and evacuation systems, surpassing the industry standard.
Plena is a plug-and-play system that includes an emergency microphone, an integrated 240 Watt power amplifier, and voice transmission for up to 6 zones. It is designed for small to medium size applications with up to 60 zones, and provides all key functions such as full system monitoring, switching to disaster amplifiers, loudspeaker circuit monitoring, an integral message manager, and comprehensive control elements and indicators on the front panel. The system is also equipped with comprehensive public address functions.
The Plena controller can be used as a stand-alone solution for small systems, but can be easily expanded to 60 zones with 6-zone routers. If more power is needed, Plena power amplifiers can be added. Optional remote control panels that duplicate the Plena Voice Alarm System user interface enable the system to be installed in a basement or fireproof cabinet, so that it can be operated from another part of the building or from a different location.
