Thanks for clarifying the finer points, my exposure to these systems is sending people to wire them up (mostly electrical but sometimes the control wiring) and not so much on the code side.

I looked up a wiring diagram for a similar gate and saw it had a fire alarm input so I assumed the AHJ in this case approved it based on the ability for the gate to open when an alarm condition is detected. That being said, it seems like a danger to me.

A regional hardware store chain has turnstiles at the entry points and swing gates at exits, which seems much safer for access control in a big box store.
