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-ofline
(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
