FYI,
The following was taken from the latest issue of LAN magazine:
The National Electricity Code has a new article, Article 800. The Article
lays down the specifications of the cable that goes in a particular place. It
seems that cabling and connections accounts for about 15% of property damage
due to fire, about 500 million. Under the Article there are essentially four
categories of cable.
0 CM (Communications Cable). Generic listing of wire and cables that are
installed as wiring in buildings and are capable of resisting the spread of
fire.
0 CMR (Communications Riser Cable) Communications wire and cables in a
vertical run in a shaft shall be Type CMR listed, as having fire resitant
characteristics capable of preventing the carrying of fire from floor to
floor.
0 CMP (Communications Plenum Cable) Communications wires and cable insatlled
in ducts and plenums or other sources used for environmental air This type of
cable will feature material that does not give off noxious gas and smoke when
it burns.
0 CMX (Communications Cable, limited use) A lower grade CM Type to be used
where: the wires and cables are enclosed in a raceway or noncombustible
tubing; the exposed length of wires or cable does not exceed 10 feet in a non-
concealed space; communication wires and cables less than 0.25 inch in
diameter and installed in one- or two-family, or multifamily housing. [This is
important given out responsibilities to the SLASC area.]
