Description
AUTRONICA
BHH-31A/EX
SMOKE DETECTOR
WITH HUBA CONTROL 604.99352
0.2-3M BAR
MAX.= 50M BAR (-30T85)
The Autronica BHH-31A/EX is an explosion-protected smoke detector integrated with a Huba Control 604.99352 pressure unit, designed for use within marine fire alarm systems. Combining smoke detection capability with a pressure-sensing element rated 0.2–3 mbar and a maximum rating of 50 mbar across a temperature range of -30°C to +85°C, this unit is suited to demanding onboard environments where reliable early fire detection is critical to vessel safety and regulatory compliance.
Key Features
✓ Explosion-protected smoke detector configuration (BHH-31A/EX designation), suitable for installation in hazardous or classified zones onboard.
✓ Integrated Huba Control 604.99352 pressure unit rated 0.2–3 mbar, with a maximum pressure rating of 50 mbar and an operating temperature range of -30°C to +85°C as stated in product data.
✓ Designed for compatibility with Autronica fire detection and alarm systems; specific panel compatibility subject to confirmation based on vessel configuration.
✓ Applicable to SOLAS-relevant fire detection installations where explosion-proof or EX-rated equipment is required in high-risk spaces such as machinery rooms or pump rooms.
✓ Replacement and service of this detector should be carried out in accordance with Autronica system documentation and relevant class requirements; exact wiring and mounting configuration subject to onboard system review.
Marine Applications
✓ Cargo vessels and tankers requiring EX-rated smoke detection in classified hazardous areas such as pump rooms and cargo spaces.
✓ Offshore support vessels and platform supply vessels where explosion-protected fire detection equipment is mandated by class or flag state requirements.
✓ Engine rooms and machinery spaces on commercial vessels where Autronica fire alarm systems are installed and periodic detector replacement is required.
✓ Chemical tankers and gas carriers where integrated pressure monitoring alongside smoke detection provides enhanced safety system redundancy.
✓ Passenger ferries and ro-ro vessels operating Autronica fire alarm infrastructure requiring like-for-like detector replacement during scheduled maintenance.
