Parallel to the effort by HMMA, an ASTM task group on detention hollow metal was hard at work developing an ASTM test method for swinging detention door assemblies.
Published in 1992, the new ASTM detention door standard, ASTM F 1450-92, was well-received in the industry.
A full-size detention door and frame with detention hardware is installed in a reinforced masonry wall for this test.
NFPA 80 does not refer to the "food-pass opening mechanisms" commonly found in detention door assemblies (whether or not they are swinging or horizontally sliding).
Overhead slider-type locks had never been tested and listed for use in three-hour fire-rated detention door assemblies.
For a prison in Oman, Al Kuhaimi is delivering detention doors
through contractor Roots Group.
Although as secure as most adult detention facilities incorporating detention doors
and hardware, solid grouted masonry walls and surveillance cameras, the spaces were designed to ameliorate the harshness of the environment through the use of color, natural materials and softer surfaces.
