AUTRONICA BS-420M AUTROSAFE FIRE ALARM CONTROL PANEL

The Autronica BS-420M is a high-performance Fire Alarm Control Panel (FACP) specifically engineered for the AutroSafe Interactive Fire Detection System. It is the heart of fire safety management on board ships, offshore installations, and large industrial facilities. Known for its “SelfVerify” technology, the BS-420M ensures that every fire detector in the system is automatically tested, providing unparalleled reliability in life-safety applications.

Product Parameters

Technical Datasheet Overview

The BS-420M is designed to handle complex, mission-critical fire safety logic.

• SelfVerify Technology: This is the hallmark of the AutroSafe system. Each detector undergoes a self-test at scheduled intervals. The system automatically checks for sensitivity and functionality without human intervention, significantly reducing false alarms and maintenance costs.

• Redundancy: The panel features a dual-processor architecture. If the main processor fails, the secondary unit takes over control instantaneously.

• Networkability: Multiple BS-420M panels can be connected via a redundant Ethernet network to form a massive, site-wide fire detection system.

• User Interface: Features a high-resolution color display with intuitive menu structures for rapid emergency response.

Application Fields

• Maritime/Shipping: Standard-fit for cruise ships, cargo vessels, and tankers to meet IMO/SOLAS fire safety regulations.

• Offshore Oil & Gas: Protection for drilling rigs and FPSOs (Floating Production, Storage and Offloading units) where high-reliability gas and fire detection is mandatory.

• Industrial Plants: Essential for petrochemical facilities and power plants where rapid detection of smoldering fires is critical.

Product Operating Instructions

Installation and commissioning must be carried out by certified Autronica personnel.

1. Loop Wiring: Use twisted-pair, shielded cabling for the AutroFieldBus to ensure noise immunity.

2. Addressing: Each device on the loop is automatically addressed by the panel during the initial commissioning (Auto-Addressing).

3. Normal Mode: Under normal operation, the green “Power” LED should be lit, and the display should show the current date/time with no active faults.

4. Alarm Handling: If a fire is detected, the display will show the precise location of the alarm. Press “Silence” to mute internal buzzers and “Reset” only after the area has been inspected and cleared of smoke/heat.

Frequently Asked Questions (Q&A)

What does a “Loop Fault” message mean? This usually indicates a break in the cable or a short circuit on the loop. The AutroSafe system uses isolators to keep the rest of the loop running even if a physical break occurs. Can I add new detectors to an existing system? Yes, the AutroSafe system is highly modular. You can add new devices to unused addresses on the loop, and the panel will recognize them through the “Auto-Addressing” feature. Why is the “SelfVerify” icon blinking? It is likely performing an internal test of a component. If the icon persists for more than 24 hours, it may indicate a detector that has failed its internal self-test and requires replacement. Can I integrate this with a ship’s AMS? Yes, the BS-420M supports Modbus and other serial protocols to forward alarm status to the ship’s centralized Alarm and Monitoring System.
