The Armoured Linear Thermal Detector (Armoured LTD) is a twin conductor cable with a heat-sensitive covering protected by an armoured metallic outer sheath. In a fire or overheat condition, the heat sensitive covering inside the armour melts, causing the conductors to short, which alarms the system.
