**Abstract:**
Fire dampers and smoke dampers are critical components in building fire protection and smoke control systems. Their testing involves five main procedures: temperature sensor performance evaluation, shutdown reliability assessment, salt spray corrosion test, air leakage inspection, and fire resistance testing. This study primarily focuses on the latter two tests—fire resistance testing and air leakage testing. These experiments are essential to ensure that fire dampers and smoke dampers can effectively prevent the spread of fire and smoke under extreme conditions. Keywords: Fire damper, smoke damper, temperature sensor, fire test, air leakage test.
**Introduction to Fire Dampers and Smoke Dampers**
A fire damper is typically installed in ventilation and air conditioning ducts. It remains open under normal conditions but automatically closes when the temperature in the duct reaches 70°C, helping to maintain fire resistance and integrity for a specified period. Similarly, a smoke damper is placed in exhaust ducts and opens normally, closing automatically when the temperature rises to 280°C during a fire, preventing the spread of hot gases and smoke. Both types of dampers play a crucial role in controlling fire and smoke movement within buildings.
**Function and Importance of Fire Dampers**
In complex ventilation and exhaust systems, dampers are essential for regulating airflow and ensuring proper distribution. Without them, it would be impossible to control where air or smoke is directed, leading to inefficiencies or even safety hazards. For example, in an air supply system, dampers help distribute air evenly across different zones, while in an exhaust system, they collect and channel smoke toward the exhaust fan. Additionally, dampers are necessary for equipment like fans, which should start under no-load conditions to reduce electrical stress and improve safety. In such cases, dampers help isolate sections of the ductwork before starting the fan.
**Installation Requirements for Fire Dampers and Smoke Dampers**
Fire dampers and smoke dampers must be installed in specific locations to ensure their effectiveness. In ventilation and air conditioning systems, they should be placed where ducts pass through fire-rated partitions, rooms with high fire risk, or at intersections between horizontal and vertical ducts. Similarly, in exhaust systems, smoke dampers are required in exhaust rooms and along main exhaust ducts. These devices activate automatically when temperature thresholds are reached, providing critical fire and smoke containment.
**Significance of This Study**
The quality of fire dampers and smoke dampers directly impacts the success of fire protection systems, influencing both building safety and occupant evacuation. Suppliers, users, and fire authorities all have a strong interest in ensuring these devices meet strict performance standards. Therefore, developing accurate and reliable testing methods is vital. Fire resistance testing and air leakage testing are particularly important, as they evaluate the dampers' ability to function under real-world fire conditions. The research also explores advanced data acquisition and analysis techniques, aiming to improve testing efficiency and accuracy. As more companies seek ISO 9000 certification, the need for robust testing procedures becomes even more urgent. This study contributes to the development of standardized testing protocols, supporting better product quality and safer building environments.
