Is the NV-EC1701, T-Bus, NV-EC1701PLS Plenum Rated?

Equipment installed in open air-handling spaces above the ceiling or below the floor must meet specific environmental and fire protection regulations since fire would spread quickly in an area of high airflow.  Plenum-rated cable, for example, complies with NEC - National Electrical Code requirements for the use of wire in areas used for air circulation within a building.
To determine whether cable complies with NEC requirements, NFPA 262 (formerly UL910) tests for flame propagation and smoke density values of electrical and optical fiber cables used in spaces transporting environmental air. Other products obtain the plenum rating when they meet UL 2043. UL 2043 tests for heat and visible smoke release from products installed in air-handling spaces.

The NV-EC1701, T-bus, and the EC-1701+ units have not undergone UL 2043 testing, but these equipment have been investigated for installation in information technology equipment (computer) rooms as defined in ANSI/NFPA 75, "Fire Protection of Information Technology Equipment," and Article 645 of ANSI/NFPA 70, "National Electrical Code" (NEC).
