General
The AD105N-1000 is a Digital Linear Heat Detection (LHD) cable with
a 105°C (221°F) fixed temperature activation rating. It has a Nylon
sheath that provides additional UV protection and increased durability
for external applications and is supplied in 1000m lengths.
The AD range of digital sensor cables provides a very sImple fixed
temperature heat detection system which can be used in many
applications where other forms of detection are not suitable.
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
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.
