Which item is NOT a basic component of a dry chemical extinguishing system?

• A. Storage Tank
• B. Piping
• C. Nozzles
• D. Control Panel

Answer: (D)

A dry chemical extinguishing system is built from three essential parts: the storage tank that holds the dry chemical powder, the piping network that carries the agent to the protected area, and the discharge nozzles that release the agent where needed. The release mechanism—such as a valve with a fusible link or a manual release—is also a core component because it enables the actual discharge of the agent. A control panel, while it may be associated with monitoring or interfacing with the fire alarm system in some installations, is not part of the basic extinguishing hardware itself and isn’t required for the system to function. So, the item that isn’t a basic component is the control panel.
