CPU BOARD
The Consilium Audio Mixer Unit (AMU), reference 5490300-00A, is a core signal-processing component within the Consilium marine fire alarm and public address system architecture. Comprising an AMU Interface Board (P/N 709880A3) and a dedicated CPU Board (P/N 709780B), this unit manages audio signal routing, mixing, and distribution across the vessel’s alarm and announcement network. Its role in ensuring reliable, intelligible audio output makes it operationally critical to fire detection and emergency communication systems aboard commercial and passenger vessels.
Key Features
✓ Functions as the central audio mixing and processing unit within Consilium fire alarm and PA systems, coordinating audio signal flow between connected inputs and output zones.
✓ Supplied complete with the AMU Interface Board (P/N 709880A3) and CPU Board (P/N 709780B), providing the essential hardware for signal management and system control — specific electrical ratings are subject to confirmation against system configuration.
✓ Designed for integration with Consilium Marine & Safety AB fire alarm and emergency communication panels; compatibility with specific system versions should be verified prior to installation.
✓ Intended for installation within protected, dry equipment enclosures typical of fire alarm panel assemblies; mounting and environmental requirements depend on the host system configuration.
✓ A direct-replacement component for maintenance and repair of existing Consilium fire alarm installations, supporting continued system integrity and SOLAS-compliant emergency signalling capability.
Marine Applications
✓ Installed aboard merchant vessels including bulk carriers, container ships, and tankers requiring SOLAS-compliant fire detection and alarm systems.
✓ Used in passenger vessels and ferries where integrated audio alarm and public address functionality is essential for emergency response.
✓ Suited to offshore platforms and support vessels operating Consilium fire alarm systems across multiple alarm zones.
✓ Applied in vessel refits and system upgrades where existing Consilium AMU hardware requires replacement to restore full audio processing capability.
✓ Relevant to any commercial or naval vessel where centrally managed audio mixing is a functional requirement of the fire safety and emergency notification system.
