EN54 VOICE ALARM SYSTEM
The compliance of certain public access buildings (hotels, schools, administrations, shopping centers) imposes heavy technical constraints. Tight budgets and reduced spaces often limit the choice of equipment. Installers face a complex equation: ensuring security according to the EN 54 standard for the Public Address part.
With the distribution of its new EVA-3000 system, Rondson offers a global solution integrating an audio matrix, monitoring, and a power amplifier in a compact chassis. This all-in-one product streamlines the security architecture of the building(s).
Compliant with NFS 61-936 requirements
Technical architecture and system control
The core of the system relies on advanced digital integration, managing the priority flows required by security commissions.
Power, channels, and line topology
The unit features a 500W RMS Class-D amplifier, distributing power across 8 distinct zones. This multi-channel architecture offers total flexibility.
- 100V Technology: Allows signal transport to the speakers over long distances without notable loss.
- A/B Redundancy: Each output zone has dual wiring (A/B line). In the event of a break on line A, continuity of service is ensured, a vital criterion for public address safety systems.
Monitoring and diagnostics
Reliability is guaranteed by continuous control without human intervention:
- Measurement of speaker line impedance (short-circuit detection).
- Monitoring of mains and battery power supply.
- The front screen displays error codes in real time.
Message management and audio inputs
The system includes memory for storing evacuation (DGM) and alert messages. The priority network is strict: fireman microphones (PTT) maintain priority over other inputs (background music, standard mic announcements), ensuring instructions are broadcast under all circumstances.
Scalable system: zone extension and associated products
For large projects, the architecture is modular. The EVA-EXT3100 extension allows adding blocks of 8 additional zones, bringing the theoretical capacity to 120 zones via 15 cascaded units. Note: the extension acts as a routing matrix and requires the addition of external amplifiers sized according to the speaker load.
Remote supervision and ergonomics
The EVA-MIC3000 microphone console allows remote zoning via CAT5 connection (up to 600m). For optimal ergonomics in an emergency situation, the addition of the EVA-EXT8B keypad provides physical buttons for each zone, avoiding navigation through LCD menus.

Installation optimization and maintenance
The economic argument for the EVA-3000 is based on reducing the TCO (Total Cost of Ownership) for the installer.
- Structured wiring: The use of CAT5/6 (shielded) cables for peripherals reduces cable pulling time and connection errors compared to traditional analog wiring.
- "Backup Amp" mode: The system allows an external amplifier to be dedicated as a backup. If the internal 500W amp fails, the switchover is automatic, ensuring the continuity of the safety function.
- Configuration export: Parameters can be saved, securing the configuration validated by the inspection body.
The role of public address and voice alarm
Voice alarm is increasingly important in the safety management of buildings. A voice message precisely informs occupants about what they must do in an emergency, and it has long been established that people react faster and are more likely to take the necessary steps during an evacuation if voice messages are used instead of a sound signal.
Voice alarm systems are not only used in public buildings welcoming a large number of visitors, but they also have the added benefit of functioning as message broadcasting, public address, and entertainment systems.
