Description
The KONGSBERG AUTRONICA EAC-300A/B-4 is a critical Processor PCB card designed for high-reliability fire detection and alarm systems. It serves as the primary intelligence module for processing sensor inputs, managing alarm logic, and coordinating safety responses within the Autronica fire detection network.
Product Overview
- Manufacturer: Autronica (a Kongsberg company)
- Model Number: EAC-300A/B-4
- Product Type: Processor PCB Card
- Application: Fire detection, fire alarm management, and integrated safety systems.
- Environment: Maritime, offshore, and industrial fire safety infrastructure.
Technical Characteristics
- Functionality: This module is responsible for real-time monitoring of detection loops, signal analysis for smoke/heat sensors, and the execution of logic programmed for emergency safety sequences.
- Version Logic: The “A/B-4” designation refers to specific iterations of the processing hardware. These variants often differ in firmware compatibility, I/O handling capacity, and circuit board layout optimizations.
- System Integration: It communicates with the broader Autronica system control panel, acting as the main interface for data acquisition from field devices such as manual call points, flame detectors, and thermal sensors.
- Build Standard: Engineered for continuous operation in harsh industrial and marine environments, featuring robust noise filtering to prevent false alarms caused by electrical interference.
Installation and Maintenance Considerations
- Configuration Compatibility: As a processor card, it requires specific firmware configurations to match the fire detection system’s layout. Ensure that the replacement card is programmed or jumper-configured to reflect the current zone and device mapping of the system.
- Component Sensitivity: Like all high-density processor boards, the EAC-300 is sensitive to electrostatic discharge (ESD). Use appropriate grounding equipment when handling or installing the unit.
- Operational Validation: After replacement, a full system self-test must be conducted to ensure all connected fire detection loops are identified and correctly reporting status to the main control console.
Caution: This module is integral to safety-critical systems. Ensure the system is set to “Maintenance Mode” prior to any physical intervention. Verify that no fire-suppression discharge relays are active before replacing the processor to avoid inadvertent deployment of fire-extinguishing agents.
