REVERSE POWER
The Autronica AKN-21A/2 is a printed circuit board (PCB) card designed for use within Autronica marine fire alarm systems. Configured for reverse power detection and compatible with supply voltages of 220V, 380V, and 440V, this card plays a functional role in maintaining the integrity and reliability of shipboard fire detection and alarm infrastructure. As a core electronic assembly within the fire alarm system, it supports the continuous monitoring and signal processing demands that SOLAS-compliant fire safety installations require onboard commercial and working vessels.
Key Features
✓ Reverse power detection functionality, providing a critical safeguard within the fire alarm system’s power management and monitoring architecture.
✓ Multi-voltage compatibility confirmed at 220V, 380V, and 440V, making it suitable for varying shipboard electrical supply configurations — subject to system confirmation.
✓ Designed for integration within Autronica fire alarm panel systems; compatibility with specific Autronica panel models or controllers should be verified against the vessel’s existing installation.
✓ PCB card format allows for direct board-level replacement within the fire alarm system enclosure, supporting efficient maintenance and minimising system downtime during servicing.
✓ Part number 7255-016.0002 assists in precise identification within Autronica’s fire alarm system component range for accurate procurement and replacement planning.
Marine Applications
✓ Shipboard fire alarm and detection systems requiring PCB-level maintenance or component replacement within Autronica panel installations.
✓ Vessels operating at varying mains supply voltages across international routes, where multi-voltage board compatibility is operationally important.
✓ Engine room and machinery space fire detection systems where reverse power monitoring contributes to overall electrical safety and alarm system performance.
✓ Passenger vessels, bulk carriers, tankers, and offshore support vessels operating under SOLAS fire safety requirements and flag state regulations.
✓ Planned maintenance schedules and corrective maintenance operations targeting fire alarm system reliability and continued class compliance.
