On actuation of any cooking equipment fire extinguishing system, all sources of fuel and electric power that produce heat to all equipment protected by the system shall do what?

• A. Be shut down
• B. Increase Output
• C. Switch to Backup
• D. Remain On

Answer: (A)

When a cooking equipment fire extinguishing system is actuated, the priority is to stop heat from continuing to be produced by the protected appliances. Shutting down all sources of fuel and electric power to that equipment does exactly that, removing the heat source and reducing the risk of re-ignition as the extinguishing agent takes effect. This ensures the suppression system can control the fire without ongoing heat input from gas or electricity fueling the appliances.

Increasing output, switching to backup power, or leaving all sources on would keep heat-generating energy active, defeating the purpose of the suppression and making control of the fire much harder. By immediately shuting down fuel and power to the protected equipment, you minimize heat and help the system do its job effectively.
