Yes I think you understand the area and it is an egress hallway. All of this is in the lower level or mechanical area of an airport.

Is the hallway and egress path? Is this an industrial type building or what is its use? Craig L.

The other questions I can't answer. I will look into these things but I mainly need to know can you mix systems in an area?

Is the electrical gear dry, i.e. no oil filled transformers? If he's wanting pre-action we'll assume smoke detection for activation. How will you keep smoke from the other side of the fence from migrating into the electrical area? Plus, there may be some building code issues here when it comes to separation of the two areas. What is the area adjacent to the electrical area used for? Craig L.

If there is that much of a clash of occupancies, a chain link fence may not be an adequate separation.
