About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Riser-Rated Fire Alarm Cable

Unshielded

Shielded

Use For:
Unshielded: Buildings
Shielded: Buildings, Interference Shielding
Flexible
Temperature Range: 0° to 140° F
Insulation: PVC Plastic

This FPLR cable is approved for use in vertical shafts and large facilities with multiple levels. It has flame-resistant insulation for use in critical circuits such as fire alarm systems and smoke detectors.

Use unshielded cable in applications where signal interference is not a concern.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices. It has an uninsulated ground wire that is not counted in the number of wires.

Duct-Rated Fire Alarm Cable

Unshielded

Shielded

Use For:
Unshielded: Buildings
Shielded: Buildings, Interference Shielding
Flexible
Temperature Range:
Unshielded: 0° to 165° F
Shielded: 32° to 165° F
Insulation: PVC Plastic

Also known as plenum cable, this FPLP cable has low-smoke insulation and can be used without conduit in duct work and above a drop ceiling. The insulation is also flame resistant for use in critical circuits such as fire alarm systems and smoke detectors.

Use unshielded cable in applications where signal interference is not a concern.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices. It has an uninsulated ground wire that is not counted in the number of wires.

Armored Fire Alarm Cable

Unshielded

Shielded

Use For: Buildings
Flexible
Temperature Range: -10° to 190° F
Insulation:
Outer: Aluminum Armor
Inner: Nylon Plastic, PVC Plastic

Prevent damage to wires for fire alarm systems, smoke detectors, and other critical circuits with this armored cable. Also known as metal clad (MC) cable, the metal armor acts as a conduit to protect the wires inside. The PVC inner insulation resists flames. Its nylon jacket is low smoke, so it can be used without conduit in duct work, under raised floors, and above a drop ceiling. This cable has a ground wire that is not counted in the number of wires.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it’s rated for your environment.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices.
