The CLS425-Cca series are 4-core installation loudspeaker cables compliant to the Cca standards of the Construction Product Regulation (CPR) regarding fire and flammability resistance in fixed installations, minimizing toxic smokes and providing optimal resistance to spreading fire.
In addition to its outstanding fire properties, the outer jacket of the cabling is smooth and durable for easy installation and pulling. The stranding keeps the cable flexible and easy to handle. The cable can be used in both indoor and outdoor or in humid environments.

LSHF stands for Low Smoke, Halogen Free. This term refers to Halogen free flame retardant thermoplastic material used as a sheathing compound in cables. In the event of a fire or when exposed to high levels of heat, the chemicals in the jacket removes heat from the flame, whilst the reaction produces water as a by-product to help quench the flame. As a result, the cable will emit very low levels of smoke, and non-toxic levels of poisonous halogen gasses.
For ease of installation these bulk cables are provided with an indication on every meter of the cable. This enables installers to have a clear and efficient indication of how many meters they still have available on their reel.
Whenever class B2ca cable is not necessary, class Cca cables provides great fire safety at a reduced cost. Check your local norms to determine where class Cca cable can be used.
