Smoke Barrier Door - Latching Hardware

What are the requirements for latching hardware on smoke barrier doors?

Any examples are for illustrative purposes only.

NFPA 101 (2012 edition) The Life Safety Code requires that smoke barrier doors are self-closing or automatic-closing, constructed of 1 3/4-inch or thicker solid bonded wood core or rated for a minimum of 20-minutes, and fitted to resist the passage of smoke.  The code does not require that smoke barrier doors have latching hardware.

Where latching hardware is installed on a smoke barrier door, it must be maintained so that it is functional or be removed.
