Niko:
Basically, when the fire supression system is activated, the MUA (make-up-air) (supply air) (intake air) MUST be put in an "OFF" state, and the exhaust fan MUST be "ON".
Additionally, any electrical cooking equipment under the hood must be de-energized upon activation of the fire supression system. All the gas appliances are shut down via a gas valve.
Control is thru the dry contacts on the fire supression controller and the contactors for the MUA and exhaust, ad shunt trip for electrical cooking appliances under the hood.
Code requirements are within NFPA. It's best to check with your local Fire AHJ as he/she can provide code in effect in your area.
