I saw an image of a tornado resistant door with a vertical, top, and bottom rods, but the bottom rod is no longer acceptable per ADA. Do tornado resistant doors have to have bottom rods?

Openings, specifically hardware, have been tested to comply with FEMA 320 and 361 that have the bottom bolt engaging into the hardware rabbet of the frame. This eliminates the bottom rod engaging into the floor and can be single acting function that would comply with ADA requirements.
