🔍 Key Concepts

• Fusible link as a temperature-sensitive device • Purpose of fire dampers in ventilation systems • How automatic vs. manually operated fire closures typically work

💭 Think About

• Think about what part of the system is actually sensing the fire condition in this type of damper • Consider which option describes an operation that would still work even if power or people are unavailable during a fire • Ask yourself which method is simplest and most reliable in high heat conditions

✅ Before You Answer

• Identify which choice directly involves heat acting on a physical component in the damper assembly • Eliminate options that depend on crew action from a remote location • Eliminate options that require electrical power or complex mechanisms to function
