first I would think that a building permit is required here because you are altering a means of egress. if they havent yet, i would refer them to the building dept.
as for door hardware, if they are outward swinging with no need to swipe, then the door hardware wouldnt be an issue. also, they are interconnected with the fire alarm to automatically unlock when the alarm is active?
next would be the fire safety plan, the plan would have to be altered to show these gates.
i would verify if there was a permit taken for the installation of these gates first, if they have been installed as they look like they have been, then i would request some for of documentation to show that there can be used here either from an engineer or architect.
