　　AD185N-1000

　　Alarmline II Digital LHD Cable 185°C (365°F) w/ Nylon Sheath - 1000m

　　General

　　The AD185N-1000 is a Digital Linear Heat Detection (LHD)

　　cable with a 185°C (365°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

　　Operation

　　The AD range冂 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
