What components of the smoke damper are required to be supplied and installed at the factory?

• A. Damper casing and seals
• B. Damper actuator and linkage
• C. Control panel and wiring
• D. Maintenance instructions and labels

Answer: (B)

The requirement that some components of the smoke damper must be supplied and installed at the factory is primarily focused on ensuring that critical components are pre-assembled to meet specific performance and safety standards. In this case, the damper actuator and linkage are crucial for the smoke damper's operation. The damper actuator is responsible for controlling the opening and closing of the damper, which is essential for preventing the spread of smoke during a fire. By having the actuator and linkage factory-installed, the manufacturer ensures that these components are properly calibrated and tested for reliability and functionality. This pre-installation also minimizes the risk of installation errors on the job site, enhancing the overall safety and effectiveness of the smoke management system. Furthermore, NFPA standards outline the importance of having these components configured correctly to achieve proper operation in emergency situations, thereby underscoring the significance of factory assembly of the actuator and linkage for compliance and safety.
