The Autronica BHH-520/EX is a multi-sensor smoke detector designed for use within marine fire alarm and detection systems. Combining multiple sensing principles into a single unit, it provides reliable early-warning smoke and heat detection across a range of shipboard environments. As a critical component within the fire alarm system category, it contributes directly to the protection of crew, cargo, and vessel integrity — fulfilling the redundancy and response demands expected of modern SOLAS-compliant fire detection installations.
Key Features
✓ Multi-sensor detection technology combining smoke and heat sensing for enhanced alarm accuracy and reduced false alarm rates.
✓ Rated operating voltage UI=15.75V with loop current LI=63.5mA, capacitance CI=21.6nF, and a maximum ambient temperature rating of TA=70℃ as specified in product data.
✓ Certified to EN 54-5, EN 54-7, and EN 54-17:2005 under certificate 1134-CPD-017, confirming compliance with European standards for heat, smoke, and short-circuit isolator performance in fire detection systems.
✓ Suitable for installation in zones where elevated temperature tolerance and multi-criteria detection are operationally required; compatibility with specific Autronica fire alarm panels is subject to system configuration confirmation.
✓ Direct replacement or service spare for Autronica-based fire detection loops onboard; firmware software version SW: 2-41 noted for reference during maintenance and commissioning.
Marine Applications
✓ Accommodation and cabin spaces aboard passenger vessels, ferries, and cruise ships where early smoke detection is critical to crew and passenger safety.
✓ Engine control rooms, machinery spaces, and pump rooms on tankers, bulk carriers, and general cargo vessels requiring robust fire detection.
✓ Offshore platforms and FPSOs where multi-sensor detection is specified for hazardous or semi-hazardous zone monitoring within integrated fire and gas systems.
✓ Galleys, laundry rooms, and service corridors where combined heat and smoke detection reduces nuisance alarms while maintaining reliable response.
✓ Naval vessels, coast guard cutters, and research ships operating Autronica fire alarm systems requiring OEM-specification replacement detectors.
