How is WCFS activated automatically?

How is WCFS activated automatically?

• A. By heat-detection devices or fusible links that trigger discharge.
• B. By a timer in the control panel.
• C. By manual pull station only.
• D. By voice-activated command from staff.

Answer: (A)

Automatic actuation of a WCFS relies on heat sensing in the kitchen hood and duct area. When cooking fires raise the temperature, heat-detection devices or fusible links reach their set point and trigger the discharge of the wet chemical agent through the suppression network. This rapid release coats the cooking surfaces and fats, saponifies fats to help smother and cool the fire, and minimizes reignition. Timers or voice-activated commands aren’t designed to activate the system, and manual pull stations require human action to release the agent.
