All components of the system are networked, thereby ensuring the highest flexibility and scalability from small centralized to large decentralized systems. The OMNEO IP architecture supports DanteTM audio networking, AES67 and AES70 protocol.
The innovative multi-channel amplifier architecture with intelligent power allocation significantly improves the effective utilization of available power, regardless of the loudspeaker load in each zone. Other powerful features like full network link redundancy and intuitive call station interface complete the system. PRAESENSA is a comprehensive system that adapts easily to changing needs. Compliant to the highest standards, it is a fit-for-purpose solution for consultants, installers and building owners alike.
PRAESENSA, connecting all the dots. OMNEO is an architectural approach to connecting devices that need to exchange information such as audio content or device control. Built upon multiple technologies, including IP and open public standards, OMNEO supports the technologies of today - such as Audinate’s Dante - while adopting the standards of tomorrow. OMNEO offers a professional-grade media networking solution that provides interoperability, unique features for easier installation, better performance, and greater scalability than any other IP offering on the market.
Voice Alarm 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, for public address applications without the need for voice alarm capability see. 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). For more information about Plena booster amplifiers - extends the Plena voice alarm system - provides an additional 6 zones - same output functionality as the controller - uses the controllers built in booster amplifier or.additional Plena booster amplifiers. Additional call stations with a flexible stem can be incorporated into the Plena voice alarm system for making business calls. Each call station has 6 programmable keys and an all call button. The call station can be extended using additional keypads containing 7 programmable keys (as shown) - standard call station with 6 programmable keys.and all call buttons - emergency call, power and fault indicators.uni-directional condenser microphone on a flexible stem - selectable gain, speech filter and limiter. 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.
