Special Equipment

Article 645, Information Technology Equipment

Alternative Wiring Prerequisites

In order to use the alternative wiring methods, Section 645.4 requires that the following conditions must be met:

There must be a disconnect that is available, typically at the designated exit doors (The 2011 Code now provides for some remote controls as well, but there must be some disconnecting means that will shut off the air conditioning and the information technology equipment in an emergency.)
Heating, ventilating and air conditioning must be supplied by separate equipment for the ITE room, or if it is served by equipment that also serves other areas it must be isolated using fire and smoke dampers wherever the room boundary is penetrated.
All the information technology and communications equipment installed in the room must be listed.
The room must be occupied only by those people who are required to be there for maintenance and functional operation. (This excludes most so-called "computer labs" because they are designed for use by non-experts, rather than being restricted to qualified people.)
The room has to be separated from other occupancies by fire-resistant rated walls, floors and ceilings with protected openings, which requires a special construction of the room.
Only electrical equipment and wiring directly associated with the operation of the ITE room is installed in that room. (An informational note explains that this could include communication systems, monitoring systems, fire alarm systems, security, water detection and HVAC.)
