ARMOURED FIRE RESISTANT SPEAKER CABLE

Norden Armoured Fire Resistant Speaker Cable is designed for reliable voice and audio transmission in fire alarm, public address, and voice evacuation systems during fire conditions. It uses stranded bare copper conductors with mica tape and PE insulation to maintain circuit integrity under fire. The cable is protected by galvanized steel wire armour and a PVC inner sheath, providing strong mechanical and rodent protection. The FR-LSZH outer jacket provides enhanced safety.
