What is the draft curtain definition in fire sprinkler systems?

The draft curtain is defined as a continuous material that protrudes downward from the ceiling, effectively channeling smoke and heat towards smoke vents. This design is crucial in fire protection systems as it helps direct the movement of smoke layers during a fire, thereby aiding in maintaining clear egress routes and minimizing smoke spread in areas that are not affected by fire. By controlling the smoke, the draft curtain plays a vital role in enhancing the overall safety of the building and the efficiency of the fire protection measures in place.

This definition signifies the importance of the draft curtain in facilitating effective smoke management strategies within fire safety design, highlighting its role as an integral component of a fire sprinkler system. It contrasts with other options, which do not accurately describe the specific function and configuration of a draft curtain in fire sprinkler systems.
