DT-200 FEMA 361 Tornado Resistant Door Assembly

Moving Tornado

With PDI’s experience producing blast, pressure and missile resistant doors for over 50 years, it was a natural fit to engineer a unit meeting FEMA 361 storm shelter door requirements.  This criteria covers tornado forces that produce complex positive and negative pressures and impulses, and severe impact conditions. 

 

PDI developed and successfully tested Door Model DT-200, a single swing steel tornado resistant door at the Wind Science and Engineering Research Center per FEMA’s 320/361 and ICC-500 standards.  The door unit is exposed to the pressure test first and after passing, the missile test is immediately conducted.

The assembly is a complete package and includes a steel door panel, steel frame, hinges and a vital component, PDI’s own brand of Sonicbar SH Series pressure resistant mortise latchset with 2-POINT HORIZONTAL LATCHING – NO archaic 3-point latching and NO bottom floor bolt.  The mortise components are factory installed with only the trim shipped loose.  Operation is simple and quick – just turn the exterior lever or depress the exit bar at the interior and open door. No messing with deadbolts, slide bolts or a floor bolt.  With the addition of a door closer, the door will automatically close and latch.
