NDC offers BDA Acceptance testing, both pre BDA acceptance testing for design implementation approval and post BDA acceptance testing for AHJ acceptance.
In order to get a building CO on a remodel, or new build, all buildings requiring ERRCS must have BDA Acceptance Testing to ensure acceptable signals are present in predetermine percentages throughout the building, such as 99% in critical areas and 95% in common areas.
BDA Acceptance Testing: Small commercial buildings such as single stories and open floor plans; the technician should set five (5) tests plots, one in each of the four corners and one in the center of the building. Medium buildings such as a small school, light industrial, or medical offices; the technician should set test plots along the core and in each corner of the building, and then set plots at a maximum of 25 ft. intervals between the previous plots in a acceptance pattern. Large buildings such as a shopping mall, a factory, or a building above five stories; the technician should plot along the core and in each corner of the building, and then set plots at a maximum of 50 ft. intervals between the previous plots in a acceptance pattern.
Results: For small commercial buildings with a small amount of plots, readings shall have a no “fail” condition, resulting in 100% of the floor area @ -95 dbm or better in signal strength. For medium and large commercial buildings with a greater number of plots, readings shall be at 90% to 99% and show readings of -95 dBm or better for General Structure and Critical Areas.
These tests shall be presented on the floor plans with signal strength measurements being reflected, showing before and after measurements.
