What happens if a fan-powered unit has a design capacity greater than 2,000 cfm?

When a fan-powered unit has a design capacity greater than 2,000 cubic feet per minute (cfm), it is subject to specific safety regulations due to the potential for increased smoke and fire hazards associated with high airflow in commercial buildings. These high-capacity systems are required to have individual smoke detectors installed to ensure that any smoke or fire can be detected immediately. This requirement is vital for early warning systems that help protect building occupants and allow for swift evacuation if necessary.

The inclusion of smoke detectors helps to mitigate risks by providing an added layer of safety, particularly in spaces where large amounts of air are being moved, thereby improving overall fire safety protocols. The installation of these detectors is crucial for systems that exceed this threshold, emphasizing the need to maintain the safety and well-being of individuals in the building.
