Active Fire Protection System

• A. A system that uses moving mechanical or electrical parts to achieve a fire protection goal.
• B. A system that relies solely on passive barriers to protect occupants.
• C. A system that shuts off HVAC to prevent smoke spread without any detection.
• D. A system that provides lighting only during a fire event.

Answer: (A)

Active Fire Protection Systems are those that perform an action in response to a fire, using moving mechanical or electrical components to achieve protection. This means components such as automatic sprinklers, fire alarms, or suppression systems physically operate to detect, alert, or suppress a fire, rather than relying solely on the building’s structure. That’s why the description of a system that uses moving mechanical or electrical parts to achieve a fire protection goal best fits.

In contrast, passive fire protection relies on the building’s construction—like fire barriers and fire-resistance rated assemblies—to slow or contain a fire without requiring active operation. The option about shutting off HVAC without any detection isn’t aligned with a coordinated, detection-driven active system, and it omits the necessary sensing and control logic. The idea of lighting only during a fire event describes emergency illumination, which is important for safety but does not define an active fire protection system focused on detection, suppression, or automatic response.
