Voice Alarm : security and evacuation sound system (compliant with standard EN54)

A security and evacuation sound system (Voice alarm) works either in addition to or in replacement of the emergency tones emitted by the fire alarm system.

People in danger are warned by clear and understandable communication.
In fact, twice as effective as a traditional siren system, a clear message broadcast by the security, evacuation or voice alarm system allows the operators or the public concerned to directly identify the instructions.

These can be pre-recorded or broadcast live by the emergency services to organize, for example, evacuations in stages or inform of the end of an evacuation.

Currently, it is the European directive "construction products" which governs the products of public address systems for security, evacuation and voice alarm forming part of or being connected to a fire alarm system. Public address and emergency alarm system products must be certified in accordance with EN54.

Our range of security products made in Europe comply with EN54 sound requirements. We also have a wide range of EN54-24 loudspeakers made in Europe.

Voice Over Internet Protocol Public Address

Voice over IP (Internet Protocol), or “VoIP” for Voice over IP, or even remote public address, carries both voice-type and music-type broadcast streams without degradation of quality.

It makes it possible to broadcast background music, a spoken announcement, a microphone console, etc., in a room or a building which is several hundred kilometers from the audio source.
The protocol following the IP (Internet Protocol) standard facilitates integration into your industrial or office network, without having to lay cables or use a dedicated Ethernet network.

Archean Technologies has designed and developed its own line of VoIP systems. Archean manufactures it's own products in Montauban since 2005.
