Description
AUTRONICA
BG-21
AUTROFLAME
IR FLAME DETECTOR
The Autronica BG-21 Autroflame is an infrared (IR) flame detector designed for use within marine fire alarm and fire detection systems. It operates by sensing the characteristic infrared radiation emitted by open flames, enabling rapid detection before fire can spread to critical areas of the vessel. As a core component in shipboard fire safety infrastructure, this detector plays a vital role in protecting crew, cargo, and vessel integrity in compliance with marine safety requirements.
Key Features
✓ Infrared flame detection technology providing fast response to open flame events, minimising false alarms from non-flame heat sources.
✓ Specific technical parameters such as voltage, detection angle, and response time are subject to confirmation based on installation configuration — consult documentation for exact values.
✓ Designed for integration within Autronica fire alarm and detection systems; compatibility with specific panels or controllers should be verified against your vessel’s system configuration.
✓ Suitable for installation in engine rooms, machinery spaces, and other onboard areas where flame detection is required under SOLAS fire safety regulations — mounting location and environmental suitability depend on system design.
✓ Intended as a direct replacement or spare component within existing Autronica Autroflame detector installations, supporting scheduled maintenance and corrective servicing programmes.
Marine Applications
✓ Engine rooms and machinery spaces aboard cargo vessels, tankers, and offshore support vessels where open flame risk requires dedicated IR detection.
✓ Pump rooms and cargo handling areas on tankers and chemical carriers where flammable substance exposure increases flame detection priority.
✓ Power generation compartments on cruise ships, ferries, and ro-ro vessels integrated into centralised fire alarm monitoring systems.
✓ Offshore platforms and FPSOs where continuous flame surveillance is required across hazardous zones and process areas.
✓ Naval and coast guard vessels requiring robust, reliable flame detection as part of integrated damage control and fire safety systems.
