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.
Linear heat detection is also sometimes know as Heat Sensing Cable, Line Type Heat Detector or Linear Heat Sensing.
Non-Resetable Line Type Heat Detector
This term refers to linear heat detectors that can not be ‘reset’ (i.e reused) after an alarm event. Instead the affected area must be replaced. Other terms for Non-resetable line type heat detectors are Digital or Fixed temperature.
Signaline has two forms of Non-resetable line type heat detectors. For European markets we offer the Signaline FT-EN which is approved to EN54 part 28. For global markets we offer the Signaline FT range which is approved to UL and FM.
Resetable Line Type Heat detector
This term refers to linear heat detectors that can be ‘reset’ (i.e reused) after an alarm event. Other terms for Non-resetable line type heat detectors are analogue linear heat detectors.
The Signaline HD range is our Resetable line type heat detector
