Do fire alarm systems have to shut down all fans in an industrial setting?

In an industrial setting, fire alarm systems typically do not automatically shut down all fans; however, they may shut down specific fans that could exacerbate a fire by spreading smoke or flames. Fans that are part of smoke control systems may remain operational to help clear smoke from the area. The specific protocols depend on the facility's fire safety plan and local regulations. It's essential to follow established fire safety guidelines to ensure safety during a fire event.
