Automatic Sliding Doors

For those who don’t have it, NZS4239 states
5.3.2 Operation
In the event of an emergency condition, power failure, or the activation of required fire or smoke alarm anywhere in the building, the automatic doors shall -
a) fully open automatically and remain open for the duration of the emergency; or
b) be able to be opened by hand under a force of not more than 110N.

I assume the door people rely on b for getting away with it. I note the 110N is higher than C/AS with sliding doors (67N?) and wedging your fingers in the crack doesn’t comply with D1 for door hardware.
