A fire suppression unit is an emergency extinguishing system in which nozzles are placed under the commercial hood over each piece of cooking equipment with an open flame (steam table exempt) if the temperature exceeds a certain amount (normally 450-500) a dry liquid powdered chemical will be dispersed and the gas will automatically be shut-off. This system also comes with a K-class fire extinguisher. Even if your local health inspector tells you that you are not required to have a fire suppression unit check with the fire marshal, he has higher jurisdiction than an inspector. Non remember if you choose not to have this unit installed and you travel out of your local area or into another state where it is required and mandatory, you will not be permitted to open and in turn will now be closed down before the event has even opened. Therefore you not only lose the money you would have made for the weekend but you would also lose your entrance fee. So to put it shortly, choosing not to have fire suppression could cost you a lot more than anticipated.
