What is the purpose of a damper position indication device as allowed in the 2019 edition of NFPA 105?

• A. To control airflow
• B. To indicate the damper's operational status
• C. To improve insulation
• D. To prevent corrosion

Answer: (B)

The purpose of a damper position indication device, as outlined in the 2019 edition of NFPA 105, is to indicate the damper's operational status. This device provides visual or audible feedback regarding whether a fire or smoke damper is fully opened or closed in its intended position. By ensuring that personnel can immediately ascertain the damper's status, the device plays a critical role in maintaining proper airflow management and safety in HVAC systems, particularly in the event of a fire. This functionality is essential for effective fire protection strategies, enabling quick responses in emergencies and ensuring that smoke containment measures work as intended. In this context, while controlling airflow is a function of dampers themselves rather than the position indication device, improving insulation and preventing corrosion are not relevant to the operational status indication, as these aspects are handled through different means in building design and HVAC equipment maintenance.
