ASPIRATION CO, DETECTION LINEAR HEAT SENSING SYSTEM
Aspiration smoke detectors deliver highly accurate very early warning fire detection and extensive communications capabilities to provide maximum control over challenging environments. Linear Heat Detection (LHD) (also known as Linear Detection Wire or Linear Heat Detection Cable or Linear Heat) is a very commonly used method of fire detection. It can detect a fire anywhere along the length of the cable, and can be of lengths in excess of a kilometer.
