We wired a small restaurant and recently did the trim-out. Nothing was on our plans or said about a fire suppression system to us until our final electrical inspection when the inspector said he couldn't pass it until it was in and passed by the fire marshal. I've got to go in the morning and wire the shunt trip breaker. Never messed with one. What do you know about them.

This is our first restaurant. I was digging deep in code. This is far different form residential.
