Upon activation of a smoke detection system, air distribution systems part of a smoke control system shall switch to which mode?

When a smoke detection system is activated, the air distribution systems that are part of a smoke control system are required to switch to "smoke control" mode. This mode is crucial for maintaining safety during a smoke event, as it helps manage the movement of smoke within a building. By activating smoke control systems, air distribution can either exhaust smoke to prevent it from spreading or pressurize safe areas to protect occupants.

Choosing the smoke control mode allows the HVAC system to actively participate in smoke management, ensuring that smoke is directed away from escape routes and minimizing the potential for smoke inhalation. The design and implementation of these systems are critical in buildings to comply with fire safety requirements set forth in codes and standards, ensuring the safety of its occupants during emergencies.
