All of these Belden Alarm Cables have NEC ratings. Parts are also available in non-plenum, plenum, and riser-rated versions. You can choose from shielded or unshielded, multi-conductor or twisted pair constructions.

Non-plenum security cables from Belden include unshielded multi-conductor CM cable, water-blocked CM cable, and CM-rated twisted pair cable. These cables are for use as general-purpose wiring and are suitable in security systems, intercom and PA systems, audio systems, and more. Unshielded multi-conductor CM-rated cable features bare copper conductors, polypropylene insulation, and a PVC jacket. Water-blocked CM-rated cables are available in shielded and unshielded constructions and suitable for use indoors or outdoors. Belden CM-rated shielded twisted pair cable with a conductor(s) is water-blocked and ideal for security and alarm systems that run through underground ductwork. Its twisted pair is individually shielded with a Beldfoil shield, the additional conductor(s) are insulated, and water-blocking tape forms an overall shield.

Riser-rated CMR cables and CL3R cables are available in shielded and unshielded multi-conductor versions. Twisted pair constructions are also carried in unshielded, individually shielded, overall shielded, and shielded twisted pair designs. All have approval for use in riser areas – or the space behind walls that run vertically from floor-to-floor in a building.

Plenum CMP and CL2P cables are also part of Allied Wire and Cable’s vast selection of Belden security cables. Like the others, they are available in a wide range of constructions to provide you with a quality solution for your application. Choose from CMP unshielded twisted pair cable, CMP shielded twisted pair cable with conductors, overall shielded CMP cable with twisted pairs, and either CMP rated or CL2P rated multi-conductor plenum cable (shielded or unshielded).

With the wide variety of Belden cables Allied carries, you are sure to find a security cable or alarm cable well-suited to even the most challenging application.
