AlarmLine II Digital EN LHD Cable 78°C

The ADE78-0*00 is a Digital Linear Heat Detection (LHD) cable with a 78°C fixed temperature activation rating. The ADE range of digital sensor cables provides a very simple fixed temperature heat detection system that can be used in many applications where other forms of detection are not suitable.

Operation

The ADE 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 connect to any fire monitoring equipment through any monitored input i.e. conventional detection zone or addressable interface unit to signal an alarm condition.

Alarm location

The control unit can identify along the length of the sensor cable where an alarm condition has occurred. The alarm location is then indicated on the display of the controller. Both zones are displayed at the same time.

Cable fixings for all applications

A range of 'edge' ,'A' , 'P' , and 'T' clips allow the cable to be properly installed. The clips provide heat insulation as well as holding the cable at the correct distance from cable trays, steelworks, ceilings and walls.
