Armag's exclusive vault construction uses continuously welded 1/4" steel, which provides a significant level of TEMPEST, ballistic and forced entry protection. I don't believe there is a need for any special dielectric fitting, since 250.96. The RF design goal is to achieve 60-dB of RF Electric/plane wave attenuation from 10-MHz to 450-MHz which is difficult to do, as well as tough to meet and hard to prove. Updates NFPA 770 With the PVC break, an electrical fire will in all probability be the heat source that trips out the circuit breakers thermal overload, as opposed to having enough time to heat it up and trip out the overload some six to ten hours later. For larger penetrations, we would split it and make (2) 3" cpvc penetrations. One exclusive manufacturer says it can produce upwards of 50-dB window from 10-Mz to 1-GHZ, which has been difficult to confirm in field tests. The corner walls are tied together, and RF sealed with a continuous shielding corner seal cap. November 7, 2016. High-Power Performance in a Compact Package. .
