Abstract: A fire suppression and control system for a commercial cooking unit having a conventional chemical fire retardant discharge system has a flexible fire curtain supported by a hood and adapted to enclose the cooking unit from the room between the hood and the floor. A housing for storing the curtain in folded condition is positioned on the hood and includes a release mechanism for releasing the curtain from the housing when a fire occurs. A heat-responsive control for discharge of the fire-resistant chemical is coupled to the release mechanism for the curtain to release the curtain at the time the fire-retardant chemical is delivered to the cooking unit. The fire-retardant chemical is preferably a Halon 1211 gas. The release mechanism includes an electromagnetic coupling which is connected through an electrical circuit to a switch at a mechanical actuator for the valve in the chemical fire-retardant delivery system.
