The challenges
What is at stake
Background music, safety and evacuation PA and conference room equipment: zoned broadcasting, pre-recorded messages, microphones and amplification, fine-tuned on site.
Instructions everyone understands
During an evacuation, a clear message guides people better than a siren alone.
Our answer
Pre-recorded messages triggered by fire detection, with priority over music.
Meetings people can hear
Microphones that feed back, speakers inaudible at the back of the room: the event suffers.
Our answer
Conference microphones, amplification and on-site acoustic tuning.
Intelligible sound
In large, reverberant spaces, speech quickly becomes unintelligible.
Our answer
Choice and placement of loudspeakers, intelligibility measurements.
Architecture
An architecture designed in layers
A sound system connects the sources, the amplification and the loudspeakers of every zone, with absolute priority for safety messages.
Every installation is delivered tested, labelled and documented, for simple operation and maintenance.
- Layer 01
Sources
Music players, paging microphones, pre-recorded messages and room sources.
- Layer 02
Matrix & priorities
Routing of sources by zone, evacuation priority, time scheduling.
- Layer 03
Amplification
Sized 100 V amplifiers, with backup for voice alarm.
- Layer 04
Lines & zones
One line per zone, monitored to detect breaks.
- Layer 05
Loudspeakers
Ceiling speakers, projectors, column speakers and horns depending on the acoustics.

Maintenance & 24/7 support
This system can be covered by a preventive and corrective maintenance contract, with priority response on critical sites.
See the plansCan different music play in each zone?
Yes. The matrix assigns a source to each zone; announcements and safety messages always take priority.
Can the sound system be used for evacuation?
Yes, if it is designed for it: suitable equipment, monitored lines, backed-up power and a link with fire detection.
Do you equip conference rooms?
Yes: table or wireless microphones, amplification, and connection to displays and video conferencing.
