Digital LHD Cable 78°C (172°F) w/ PVC Sheath PROLINE TH78

TH78 - Digital LHD Cable 78°C (172°F) w/ PVC Sheath ProLine

The TH78 is a Digital Linear Heat Detection (LHD) cable with a 78°C (172°F) fixed temperature activation rating. It has a Standard PVC outer sheath making it suitable for internal applications and is supplied in 100m, 200m, 500m and 1000m lengths.

Special Application Fire Equipment ProLine Digital Linear Heat Detection Cable uses fixed temperature detection technology to provide an easy method for sensing changes in temperature levels. The cable can offer alternative overheat protection in a vast range of applications and environments, from tunnels, cable trays, warehousing to sensing changes in temperature within escalators and other applications where many risks of fire are hidden from view.

Operation
The TH range of digital LHD cables contains a pair of twisted, low resistance, tri-metallic conductors sheathed with advanced temperature sensitive polymers. The cable operates by softening the insulation of the conductors, the tension of the twisted conductors then causes the two cores to fuse together. The sensor cable is used in combination with the controller and end-of-line (EOL) unit, and can connected to any fire monitoring equipment through any monitored input i.e. conventional detection zone or addressable interface unit to signal an alarm condition.
