How are sprinkler heads in deluge systems configured?

In deluge systems, the configuration of sprinkler heads is such that they are open all the time. This design feature allows water to flow freely through the system once it is activated. Deluge systems are typically employed in environments where the risk of fire is significant, necessitating a rapid and extensive response to control flames.

When a deluge system is triggered, often by a heat detector or other initiating device, water is discharged from all open sprinkler heads simultaneously. This approach ensures that a larger area can be saturated with water quickly, which is particularly effective for combating large-scale fires or fires involving hazardous materials.

The open configuration is crucial for the functioning of deluge systems, differentiating them from other sprinkler systems, such as wet or dry pipe systems, which have closed heads that only operate when individual detectors sense heat. This distinctive characteristic makes the deluge system well-suited for specific applications, including industrial settings and areas with high fire risks.
