Kitchen Hood Fire Suppression System:

A kitchen hood fire suppression system is an automatic or manual, pre-engineered safety system designed to protect commercial kitchens by detecting high heat, suppressing fires at the source (ducts, plenums, appliances) using wet chemical agents, and shutting down cooking appliances. Using heat-sensitive tubes or fusible links, these systems instantly release liquid agents to create a saponified foam layer that cuts off oxygen and prevents re-ignition.
