The automatic fire detection system uses advanced sensors to monitor the kitchen for excessive heat or flames. When these conditions are detected, the system is immediately activated, releasing suppressant chemicals within seconds. This quick response is vital for preventing fires from spreading and causing significant damage or injury.

Fire Suppressant Chemicals

Specially formulated wet chemical agents are employed to combat grease fires, which are challenging to extinguish with water. These agents form a thick foam or film that cools the burning grease and isolates it from oxygen, effectively smothering the fire. Additionally, the chemicals prevent reignition, offering robust fire control in the dynamic environment of a commercial kitchen.

Manual Activation Option

For added safety, the system includes a manual activation feature. This option is typically installed near cooking stations and allows staff to activate the suppression system themselves if they notice a fire before the sensors do. The manual control ensures a faster response under urgent circumstances and serves as a reliable backup to the automatic system.

These components, working seamlessly together, provide a comprehensive safety net for commercial kitchens. By maintaining a balance of automated technology and manual control, the system ensures fire risks are handled efficiently, protecting lives, property, and business continuity.
