Fire Safety Cables

Fire Performance cables are categorized into 2 categories – Fire Alarm Cable & Fire Survival Cable. Fire alarm cables are used in internal and external places such as schools, hospitals, meeting rooms and shopping centers where safety regulations must be taken against fire. These cables can be preferred in heat detectors, smoke detectors, emergency lights, exit signboards, fire command centers and fire security systems. Metal foil shield types protect the signal from electromagnetic interference and provide continuity in signal quality. HFFR cables are less flammable in case of fire, mostly self extinguishing, have low smoke density and they do not emit poisonous and corrosive gasses during fire. Fire Survival Cables are armoured cables used for power circuits in the fire panels. All the above cables have to be used with complete halogen-free construction.
