Product Introduction of LSZH Shielded Fire Resistant Multi Core Alarm Cable
This LSZH shielded Fire Resistant Alarm cables multi core alarm cable is manufactured with latest technology to ensure consistent quality and reliability. We use good quality ceramifiable silicone rubber insulation and pure copper and LSZH sheath material( Low Smoke Zero Halogen). We use eco-friendly materials,RoHS compliance. This cable intend to assure service during a fire but are chosen to prevent the flame spreading,offer continued functionality of critical systems in the event of fire.
Application :
LSZH sheath Fire Resistant Alarm cables (2 cores or more )often used in building Management Systems(BMS),control and instrumentation, like voice alarm systems, emergency and escape lighting and other essential service control circuits. Fire protection system,emergency lights,sprinklers,ventilation devices,smoke alarm,emergency lighting system,fire alarm system.
