Which system actively controls or extinguishes fires, such as sprinklers?

• A. Detection system
• B. Alarm system
• C. Suppression system
• D. Exit signage

Answer: (C)

Active fire suppression involves systems that directly intervene to stop or slow a fire, such as sprinklers that release water to cool and dampen flames. Detection systems sense heat or smoke and trigger responses, but they don’t fight the fire themselves. Alarm systems warn occupants and coordinate evacuation. Exit signage helps people find their way out and doesn’t affect the fire. So the system described as actively controlling or extinguishing fires is the suppression system.
