What incorporate a detection system, which can eliminate concerns over water damage and false activation...

Pre-action sprinkler systems are designed to prevent accidental water discharge. These systems include a detection component (such as smoke or heat detectors) that must activate before the water enters the pipes. They are often used in areas where water damage would be catastrophic (e.g., data centers, museums).

Discovery system (A), Exposure (B), and Post-action system (C) are not standard terms in fire suppression.

“Post-action system” is incorrect; the correct terminology is “pre-action system.”
