Which system is designed so that valve activation immediately sends water to every sprinkler head?

• A. Deluge system.
• B. Wet-pipe system
• C. Dry-pipe system
• D. Pre-action system

Answer: (A)

The deluge system is designed to ensure that when the valve is activated, water is sent to every sprinkler head simultaneously. This type of system is commonly used in high-risk areas where rapid fire spread is a concern, such as in warehouses filled with flammable materials or in large open spaces without partitions. In a deluge system, the sprinkler heads are typically open (not sealed) and are not triggered individually; instead, they all activate together once the system detects a fire through an alarm or detection system. This allows for a quick and overwhelming application of water over a large area, which is essential in combating fast-burning fires. In contrast, the wet-pipe system contains water in the pipes at all times but only delivers it to the sprinkler head activated by heat. The dry-pipe system stores water under pressure in a tank, which then fills the pipes when a sprinkler is activated. The pre-action system requires a two-step activation process, where a fire detection system must first activate before water is released into the pipes and delivered to the sprinklers. None of these systems provides the simultaneous water flow to all sprinkler heads like the deluge system does.
