🔍 Key Concepts

• How automatic fire dampers are designed to CLOSE when there is excessive heat or smoke • Difference between a simple temperature-sensitive device and an electrical detection/control system • What actually releases or trips the damper blades to shut the duct

💭 Think About

• Ask yourself: does the damper need electricity to operate, or will it still close if all power is lost in a fire? • Which option is most commonly mounted directly on or near the damper to react locally to high temperature? • Which devices listed are mainly for ALARM or SYSTEM activation rather than mechanically tripping a damper?!

✅ Before You Answer

• Identify which choice is purely mechanical/temperature-sensitive and can work with NO power • Eliminate any options that mainly serve as detection/indicator rather than the actual tripping mechanism • Think about the device that would physically release the damper blades when heated in a fire
