I noticed a fire alarm panel today being wired. It was on the load side of a transformer (SDS). The load went from the transformer to the fire alarm panel's main bus bar. From there the bus bar feed individual fuses and then to the load of whatever the firealarm was feeding. More than likely fire alarm panels that feed boards or damper motors or both.

My question is the panel itself did not have any main breaker in it. And there were multiple circuits. Like 12.
Code reference? Or could you point me in the right direction as why this is allowed?

Your description of the physical arrangement is a bit confusing. No fire alarm panel I have seen or with which I am familiar has a "bus bar", unless you are using that terminology differently than I imagine, which is as if it were a bus bar in a breaker panel. Do you have a picture you can post?
