FPN No. 1: Cable types are listed in descending order of
fire resistance rating, and multipurpose cables are listed
above communications cables because multipurpose
cables may substitute for communications cables.
FPN No. 2: See the referenced sections for permitted uses.
800.51 Listing Requirements for
Communications Wires and Cables and
Communications Raceways. Communications
wires and cables shall have a voltage rating of not less
than 300 volts and shall be listed in accordance with
800.51(A) through (J), and communications raceways
shall be listed in accordance with 800.51(K) through
(L). Conductors in communications cables, other than
in a coaxial cable, shall be copper.
FPN: See Section 800.4 for listing requirement for
equipment.
(A) Type CMP. Type CMP communications plenum
cable shall be listed as being suitable for use in ducts,
plenums, and other spaces used for environmental
air and shall also be listed as having adequate fire-
resistant and low smoke-producing characteristics.
FPN: One method of defining low smoke-producing
cables is by establishing an acceptable value of the
smoke produced when tested in accordance with
the NFPA 262-1999 Standard Method of Test for Fire
and Smoke Characteristics of Wires and Cables, to a
maximum peak optical density of 0.5 and a maxi-
mum average optical density of 0.15. Similarly, one
method of defining fire-resistant cables is by estab-
lishing a maximum allowable flame travel
distance of 1.52 m (5 ft) when tested in accordance
with the same test.
(B) Type CMR. Type CMR communications riser cable
shall be listed as being suitable for use in a vertical
run in a shaft or from floor to floor and shall also be
listed as having fire-resistant characteristics capable
of preventing the carrying of fire from floor to floor.
FPN: One method of defining fire-resistant charac-
teristics capable of preventing the carrying of fire
from floor to floor is that the cables pass the
requirements of the ANSI/UL 1666-1997 Standard
Test for Flame Propagation Height of Electrical and
