Home Sprinkler System and Grease Fire? - what do you do in the event of a grease fire

I build my new house and share the view of a sprinkler system, just because he was burned (therefore) Check Conversion and I'm paranoid that fire today ...
I understand that the whole system and everything, but what if you have a grease fire in kitchen? Your irrigation system is connected to the water main and water spray irrigation in the kitchen with a grease fire (or fire, for that matter). But the water, the grease fire bigger? Thus, in the case of a grease fire, use no more harm than the sprinkler system?
