Where to buy?


The CMC222-Cca is a high quality installation microphone cable 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 improved fire properties, the outer jacket of the cabling is smooth and durable for easy installation and pulling. It consists of stranded conductors with an aluminum foil shielding and drain wire, which guarantees a high installers convenience. The highly effective shielding guarantees an excellent immunity against noise and interference caused by external devices. The stranding keeps the cable flexible and easy to handle.

Cable properties

Meter indicator

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.


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.


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.

Tinned copper drain wire

The drain wire is a part of a shield within a cable that reduces the resistance from any point on the shield to ground. A drain wire carries extraneous electrical noise to ground and away from the circuit or system. The tin plating also adds to the copper in the cable as it not only helps to boost the copper’s properties, it also helps the wire to last much longer and counter acts against oxidation.

Aluminum Foil

Aluminum foil shielding is ideal for reflecting electromagnetic interference (EMI) and is often used in combination with a braided wire to absorb EMI.

Stranded copper

A stranded copper wire is more flexible and easier to install than a large single-strand wire with the same cross section. Stranding improves wire life in applications where flexibility is needed. A particular cross section of a stranded conductor gives it essentially the same resistance characteristics as a single-strand conductor, but with added flexibility.
