Armoured Linear Thermal Detector

Armoured Linear Thermal Detector


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 overhead condition, the heat sensitive covering inside the armour melts, causing the conductors to short, which alarms the system.

210° C

Operating temperature
356° F

Note: If the wire alarms to a fire, the wire must be replaced prior to returning the system to service.
