18/6 stranded plenum security wire

18/6 stranded plenum alarm security wire plenum 1000ft is a type of cable that is commonly used in security and alarm systems. The "18/6" refers to the gauge and number of conductors in the cable. Specifically, it means that the cable has 18 gauge wire and 6 conductors.

The term "stranded" refers to the fact that each conductor is made up of multiple smaller wires that are twisted together. This makes the cable more flexible and easier to work with than a solid wire cable.

The term "plenum" refers to the type of insulation used on the cable. Plenum-rated cables are designed for use in air handling spaces such as ventilation ducts, where they are required to meet certain safety standards to prevent the spread of fire or smoke.

The cable is also described as being "1000ft" in length, which means that it comes in a spool containing 1000 feet of cable.

Overall, this cable is designed to provide a reliable and safe connection for security and alarm systems in commercial and residential buildings.
