🔍 Key Concepts

• Galley ventilation fire dampers and how they are tripped in a localized fire • How passive, automatic mechanical devices work without electricity or control circuits • Difference between detection devices (heat/smoke/pressure switches) and mechanical release devices

💭 Think About

• Ask yourself: if power is lost in a fire, what simple device could still reliably cause a damper to close? • Consider which option would be mounted directly in or near the damper/ductwork and physically release it when exposed to heat. • Which choices are primarily used to start an alarm or extinguishing system, and which is used to mechanically release something (like a door, damper, or flap)?

✅ Before You Answer

• Identify which option is a mechanical element that weakens or melts with heat. • Eliminate options that mainly serve as electrical sensors for alarm or CO₂ systems rather than for directly closing a damper. • Think about what device would be found in each individual damper rather than just in a central control or alarm panel.
