🔍 Key Concepts

• Ventilation fire dampers purpose and normal position in ducts • Difference between automatic heat-activated devices and systems controlled by detectors or CO2 • Typical use of fusible links in marine fire protection hardware

💭 Think About

• Which option describes something that works locally at the damper itself without needing another system to operate first? • On a ship, if power or control systems fail during a fire, which method would still cause the damper to close? • Which devices are most commonly attached directly to louvers, fire doors, or dampers to make them release in high heat?

✅ Before You Answer

• Check which methods are primarily used to detect fire (heat/smoke) versus methods that directly release mechanical devices • Think about which option is truly automatic and fail-safe, requiring no external signal, power, or gas pressure • Recall where fusible links are typically installed (e.g., galley hood systems, fire doors, dampers) and how they operate in high temperature
