Plena voice alarm system
 
The Plena voice alarm system is designed for public address and emergency evacuation in small to medium sized applications, such as factories, offices, shopping malls, supermarkets, sports facilities, schools and universities.

All the essential EVAC functionality - such as system supervision, spare amplifier switching, loudspeaker line surveillance, digital message management and fireman's panel interface - are combined with proven Plena audio technology to guarantee excellent speech intelligibility and message delivery.
   
The Plena voice messaging system is developed for easy operation under stressful conditions. The Plena complies with tough IEC60849 standard (and national equivalents). With emergency call (EMC) and background music (BGM) audio channels up to 60 zones, 8 call stations and 2 remote panels, the Plena voice alarm system offers extensive possibilities. It is fully compatible with the Plena BGM source and power amplifier range.

For larger evac applications see Bosch Praesideo, for public address applications without the need for voice alarm capability see Bosch Plena public address.

Up to 9 routers can be incorporated into a Plena voice alarm system to expand it up to 60 zones. Each router handles an additional 6 zones and features the same output functionality as the controller (except for the BGM volume controls). Additional Plena booster amplifiers can be incorporated if two channel operation or extra power is required (up to 480W per 6 zones max).

To allow the Plena voice alarm system to be located in a fire-resistant cabinet or in a secure location, one or two remote control panels, including remote control panel extensions can be incorporated into the system. Each panel duplicates the controls and indicators on the controller and router's front panels (limited BGM control) including the built-in emergency microphone. Interconnection to the Plena voice alarm controller is made using standard RJ45 connectors and CAT5e cable. Both the remote control panel are fully supervised.

In many situations the Plena voice alarm remote control panel can be used as a Fireman's panel. However, the regulations for fireman's panels vary from country to country, so Plena is designed to allow custom EVAC compliant panels to be incorporated into the system design.
