is not being provided by others, the TC shall provide the pathway. The pathway
shall be EMT conduit in common areas, or wiremold metallic raceway in
classroom/office areas.
7. All equipment and materials installed in plenum environments shall be UL rated
acceptable for plenum environments.
8. Cables shall be installed above fire-sprinkler systems and shall not be attached to
the system or any ancillary equipment or hardware. The cable system and support
hardware shall be installed so that it does not obscure any valves, fire alarm conduit,
boxes, or other control devices.
9. Any cable damaged or exceeding recommended installation parameters during
installation shall be replaced by the TC prior to final acceptance at no cost to the
