J-Y(St)Y Lg fire alarm installation cable - Applications

This installation cable can be used for fire alarm, in fixed installations within dry or damp premises, under or on plaster; it can also be used for fixed installations on external walls.

It must not be directly laid in ground or water, and it is not intended for supply purposes.

Furthermore this cable is suitable for applications at small bending radius.

The electrostatic screen protects transmission circuits against external disturbing electromagnetic impacts.
