Commercial Cooking Suppression Systems


All plans including applications should be emailed to the Fire Marshal's Office at 

A commercial cooking suppression system is a pre-engineered system designed to provide a manual/automatic suppression system for commercial cooking operations. Since most commercial cooking requires the use of large grills, deep fat fryers and other grease producing appliances, it is a requirement of the fire code to have a system that can provide adequate ventilation and suppression in the event of a fire. Most systems provide positive and negative ventilation that allows the vapors to be captured and vented from the building. These systems are also designed to turn off the gas and electric used by the cooking appliances. Although small fires may happen under the hood from normal cooking, the system is designed to extinguish and contain large often unattended cooking fires.
