The Autronica BHH-320 is a multi sensor smoke detector head designed for use within marine fire alarm systems. Combining optical smoke and heat sensing technologies in a single detector head, the BHH-320 provides enhanced detection accuracy by reducing false alarms while ensuring rapid response to genuine fire conditions. It is intended for integration into addressable fire detection loops onboard vessels where reliable, continuous monitoring is operationally critical. As a core component of a ship’s fire alarm system, this detector head plays a direct role in crew safety, cargo protection, and SOLAS compliance.
Key Features
✓ Multi sensor detection head combining smoke and heat sensing for improved fire discrimination and reduced false alarm rates.
✓ Certified to EN 54-5, EN 54-7, and EN 54-17:2005, confirming compliance with European standards for heat, smoke, and isolator module performance in fire detection systems.
✓ Compatible with Autronica fire alarm and detection systems; subject to confirmation for specific loop controller or panel compatibility depending on vessel configuration.
✓ Suitable for installation in enclosed onboard spaces including machinery spaces, accommodation areas, and other protected zones — exact environmental ratings subject to system documentation.
✓ Designed as a replaceable detector head, allowing field servicing without full loop replacement; software version SW: 2-41 noted for reference during commissioning or swap-out.
Marine Applications
✓ Installed within addressable fire detection loops on commercial cargo vessels, tankers, and passenger ships requiring multi-zone fire monitoring.
✓ Used in accommodation blocks, control rooms, and enclosed technical spaces where early fire detection is essential to crew safety and operational continuity.
✓ Applied in fire alarm systems on offshore support vessels and platform supply vessels where SOLAS-compliant detection equipment is mandated.
✓ Suitable for integration into vessel fire safety upgrades or detector replacement programmes during dry-dock or scheduled maintenance periods.
✓ Relevant to any vessel class operating under flag state or class society requirements for approved multi sensor fire detection equipment.
