Which statement about a deluge system is incorrect?

In the context of deluge systems, the focus is primarily on how they operate and the requirements for supervision and detection. Deluge systems are designed to provide rapid and widespread water coverage over a large area, often in situations where highly hazardous materials are present.

Automatic supervision is crucial for deluge systems, as they rely on prompt activation through specific detection devices to control water flow. These systems feature open sprinklers that deliver water uniformly across an area to combat fires effectively.

While it is valuable for personnel to understand the state of the system, the detection devices associated with deluge systems do not require manual supervision. They are designed to function automatically, triggering the deluge if certain fire conditions are met. Therefore, the assertion that detection devices should be manually supervised is misleading; they serve better when operating autonomously for rapid response in emergencies.

In summary, the incorrect statement highlights a misunderstanding of how deluge systems' detection components are intended to operate, emphasizing the need for automatic rather than manual oversight.
