Previdia Ultra Control Panel
Integrated technology for fire detection and voice evacuation
Previdia UltraVox is the first fire alarm control panel that integrates the most advanced technologies for fire detection, voice evacuation (EVAC), and public address (PA) into a single solution. Its highly flexible, modular architecture is designed to ensure maximum efficiency and safety in complex environments such as shopping centers, healthcare facilities, railway stations, and metro systems. It combines fire detection, extinguishing control, gas detection, and emergency lighting with clear, localized voice announcements during emergency situations. In addition to supporting critical emergency scenarios, it can also be used for routine public messaging and background music. Previdia UltraVox complies with the main European safety standards – including EN54‑2, EN54‑4, EN54‑16, EN54‑21, EN12094‑1, and EN54‑13 – confirming its outstanding quality and reliability.
High-performance, intelligent and connected system
Previdia is based on a distributed intelligence architecture, featuring a microprocessor on each module, a redundant main unit, and a dedicated audio DSP. The system manages up to 50 digital audio channels on the IDANET network and up to 30 Class D amplifier modules per control unit, each with an output of up to 250 W and high efficiency. Remote control is comprehensive and accessible from anywhere via web server, cloud, Inim app, TCP-IP, email, GSM, and telephone communications. Configuration is simple and intuitive thanks to dual LCD displays, graphical maps, and video verification.
The modular design allows for the integration of up to 32 IFM or IFAM modules per control unit and the expansion of the network to include up to 48 control units per cluster and 20 clusters over TCP/IP. Previdia can manage up to 24 fire suppression channels.
