Which statement best describes active fire protection systems?

• A. Active systems require activation during a fire (sprinklers, alarms).
• B. Active systems are built into the structure and do not require action.
• C. Active systems are decorative elements only.
• D. Active systems never fail and always work.

Answer: (A)

Active fire protection systems are those that must be activated to operate during a fire. They respond to a detection event or manual trigger, and then perform the protective action, such as releasing water through sprinklers or sounding alarms. The key idea is the need for an activation to initiate protection, rather than protection that is always present without any triggering.

This is why the statement is the best description: it captures that activation is the mechanism that starts the protection, with examples like sprinklers and alarms. Structures built into the building that don’t require action describe passive protection, which is different. Decorative elements have no protective function, and no system is guaranteed to never fail, so saying they always work isn’t accurate.
