Autronica BSD-340-2 Product Details
1. Product Overview
The Autronica BSD-340-2 is a high-sensitivity marine smoke and heat detector engineered for fire safety systems in maritime and offshore environments. It serves commercial ships, offshore oil & gas platforms, and coastal facilities—focusing on early detection of smoke and abnormal temperature rises, which are critical for triggering timely fire alarms and emergency responses to protect personnel and assets, complying with IMO (International Maritime Organization) fire safety standards.
Integrating dual-sensing technology (photoelectric smoke detection + heat detection) and maritime-grade ruggedness, it ensures reliable performance in harsh marine conditions (e.g., high humidity, salt spray, vibration). Compatibility with Autronica’s fire alarm control panels (e.g., AutroSafe series) and standard maritime communication protocols makes it a core component for marine fire safety systems.

3. Product Specifications & Features
3.1 Core Specifications
The Autronica BSD-340-2 is optimized for marine fire detection, combining photoelectric smoke sensing and fixed-temperature heat detection to minimize false alarms while ensuring early fire detection. Its 70°C standard heat threshold is tailored for typical marine spaces (e.g., engine rooms, cargo holds), with optional higher thresholds for high-temperature areas like boiler rooms.
The 2-wire design simplifies installation in existing marine fire alarm systems, reducing wiring complexity and cost. The detector’s low standby current (≤12 mA) ensures efficient power usage, critical for marine systems where power resources may be limited during long voyages.
3.2 Key Features
-
Dual-Sensing Reliability: Combines smoke and heat detection to avoid false alarms from marine humidity or dust, while ensuring no fire escalation.
-
Maritime-Grade Durability: 316L stainless steel housing, IP67 protection, and salt spray resistance withstand harsh offshore/shipboard conditions.
-
Clear Status Indication: Color-coded LEDs provide on-site visual feedback, simplifying maintenance and fault troubleshooting.
-
Easy Integration: 2-wire compatibility with Autronica and standard marine fire alarm panels enables plug-and-play installation.
-
IMO Compliance: Meets international maritime fire safety standards, ensuring regulatory compliance for global shipping operations.
