Voice Alarm Systems

Voice Alarm systems also called Voice Evacuation systems are essential to ensure the security of people in public buildings. The ATEÏS Voice Alarm systems are designed in compliance with the EN54 standard.

From the smallest to the largest applications, we provide several solutions for voice evacuation, paging, public announcements and background music. Our Voice Alarm systems can also be used every day as a Public Address system, in this case we name it PA/VA (Public Address / Voice Alarm) system.

Find out our Voice Evacuation systems and select the best adapt to your project: PRIMA VA is the new ATEÏS self-amplified compact system with built-in amplifiers, IDA8 is a network PA/VA system with specific attributes for compliance in large installations, and BOUTIQUE is a compact and self-amplified PA/VA system available in rackable and wall mount versions.

Frequently Asked Questions

Audio over IP (AoIP) is a technology that allows digital audio signals to be transmitted over standard IP networks such as LAN, WAN, or the internet. Instead of using dedicated audio cables, audio is converted into data packets and streamed in real time.

Audio over IP systems are widely used in:
  • Shopping malls
  • Hotels and hospitality venues
  • Museums and theme parks
  • Hospitals and schools
  • Multi-site infrastructures
These environments benefit from flexible and network-based audio distribution.

ATEÏS offers a complete range of IP audio devices:
  • IP paging microphones
  • IP audio encoders and decoders
  • IP matrices
  • IP loudspeakers
  • Control software
These components form a fully integrated audio distribution system.

  • Unicast: one audio stream per receiver
  • Multicast: one stream shared by multiple receivers
Multicast is more efficient for large installations, as it reduces network load.

Key factors include:
  • Network bandwidth and quality
  • Latency and packet loss
  • Audio codec selection (e.g., G.711, MP3, Speex)
A well-designed network ensures stable and high-quality audio transmission.

Audio over IP offers several advantages:
  • Use of existing IT network infrastructure
  • Reduced installation costs (no dedicated audio cabling)
  • High flexibility and scalability
  • Centralized control and monitoring
It is a modern alternative to traditional analog audio systems.

Audio signals are:
  • 1. Captured or generated (microphones, music sources)
  • 2. Converted into digital data
  • 3. Sent over IP networks using protocols like RTP/UDP
  • 4. Decoded and played through speakers
This process enables real-time audio streaming across multiple zones.

PoE (Power over Ethernet) allows devices to:
  • Receive both power and data through a single network cable
  • Eliminate the need for local power supplies
  • Simplify installation and reduce costs
This makes deployment faster and more flexible.

Yes, Audio over IP solutions can integrate with:
  • Traditional 100V audio systems
  • SIP-based telephony systems
  • Third-party IP devices using standard protocols
This ensures interoperability and easy system upgrades.

Audio over IP enables:
  • Scalable multi-site audio distribution
  • Real-time control and monitoring
  • Easier integration with IT and AV systems
It is now a key technology for next-generation Public Address and Voice Alarm systems.
