Operation
The AD 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 provides a sImple switch operation which
when used with a combination of end-of-line (EOL) monitoring
and alarm trigger resistors can signal an alarm to any fire
monitoring equipment through any monitored input i.e.
conventional detection zone or addressable interface unit.
Location Control Unit
Additional to the LHD sensor cable, an optional digital location
control unit which monitors the sensor cable and can identify
along the length of the sensor cable where an alarm condition
has occurred, is also available.
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, steel
works, ceilings and walls.
