Brian,
Great write up as always. In regards to the AHJ being the final say in the interpretation of codes and implementation of specific types of hardware what has been your experience in the approval or denial process? Specifically when a certain type of hardware (ie. maglocks) are approved/denied did your AHJ provide documentation citing the approval/denial or has it always been verbal? If they don't provide documentation on approval should the integrator provide something for them to sign off on related to the project?

I'm a little surprised there is no mention of electric latch retraction and electrified handset, which really is the preferred method as it maintains the integrity of the original door hardware. The different types of power transfers can be a good note, eg. hinges, door cords, EPT, concealed door cords. I always try to consider one of these options before a strike, and certainly before a maglock. Also, the difference between solenoid and stepper motor latch retraction - and latch retraction retrofits.

Can a cylindrical latch always be replaced with a deadbolt without any additional working of the door or jamb? And vice-versa?

Found this door yesterday.
If I'm not mistaken the IBC codes are the basis in Mexico,
so this door would not be complying with regulations. Although
it has a sign off sheet on the door stating otherwise.
Issues I see:
1. Door is blocked; it's a small thing but can cause trampelin
2. Big deadbolts on top and in the bottom, not sure if they were actually used.
Although this is the secured side of the door, it is a public stairwell leading to
a public garage, and all wires are exposed. Not sure if this is a good idea.There is
no camera overseeing the door.
*Edit* Not sure why when uploading the image flips sideways, sorry

Returning to say "potentially disruptive to aesthetics" is perhaps the most professional way I've heard something be called "ugly"
