Acronyms
The following is a list of acronyms common to the industry and used throughout this manual.
ASTM
– American Society for Testing and Materials: A voluntary leader in the development of
consensus standards for product definition, testing and certification. Most perimeter security products
are tested by 3
rd
party testing/engineering agencies, using ASTM standards.
BBU
– Battery Backup Unit: An optional enclosure containing components and batteries necessary to
run control electronics and/or barrier actuators.
CO
– Clear Opening: The opening distance of a barrier that is unimpeded or “clear” of any obstructions.
For wedge barriers, this typically refers to the width of the attack plate/assembly size. For arm barriers,
this commonly refers to the distance between stanchions that is clear to traffic. Clear opening does not
mean overall size or in the case of arm barriers, arm length.
