Fire Survival Cables

Our fire Survival cables are specifically designed for augmented fire resistance in applications including the delivery of power and auxiliary control in fire alarm systems, voice alarm systems, and emergency lighting systems. These cables will form part of the requirements installation of fire-resistant power and control cable systems for life safety and fire-fighting applications

These fire resistant single core and multi-core cables are suitable for use within a number of Control Circuit categories. For added protection against the risk of mechanical damage, we supply robust cables which are suitable for indoor and outdoor applications.
