Application

Application

Standards

 

Installation cable for transmission of fire alarm signals, for fixed installation within dry or damp premises, under or on plaster, also for fixed installation on external walls. Not for direct laying in ground or water, not intended for supply purposes. Electrostatic screen protects transmission circuits against external disturbing electromagnetic impacts.
