In a deluge system, what happens when the system is activated?

• A. Water flows from all sprinkler heads.
• B. Water flows from only the hottest head.
• C. Water is released only into the main line.
• D. The system releases no water until a pilot valve opens.

Answer: (A)

In a deluge system, when the system is activated, water flows from all sprinkler heads simultaneously. This type of fire protection system is designed specifically for high-hazard areas where rapid fire spread could occur, such as in warehouses or hangars housing flammable materials. The unique feature of a deluge system is its open sprinkler heads, which do not have individual heat-sensitive elements. Instead, they are connected to a common pipe network that releases water all at once when the system is activated, typically by a smoke or heat detector. This allows for a large volume of water to be available immediately across the entire area, effectively soaking the potential fire source and helping to control or extinguish the flames quickly. In contrast, other systems, such as wet pipe systems, operate on the principle of only activating the heads nearest to the fire. Understanding how a deluge system functions is crucial for effectively managing fire risks in areas prone to large-scale fire hazards.
