In a deluge system, how are the sprinkler heads activated?

• A. By heat detection
• B. Manual pull stations
• C. By water flow detection
• D. All heads open simultaneously

Answer: (D)

In a deluge system, all sprinkler heads open simultaneously when the system is activated. This system is specifically designed for high-hazard areas where a rapid and extensive discharge of water is necessary to control or extinguish a fire. The unique feature of the deluge system is that it uses open sprinkler heads, meaning that they do not activate individually based on temperature or heat. Instead, the activation involves a detection system that triggers the release of water through every sprinkler head at once, ensuring that the entire area is flooded promptly with water. This method is particularly effective in scenarios where the fire can spread rapidly, as it allows for immediate and widespread water coverage, minimizing potential damage and improving safety. The overall design criteria prioritize the need for fast action to combat fires that could escalate beyond control if not addressed quickly.
