The AAN-0500 is an analogue linear heat detection cable in a Nylon outer sheath, supplied in 500m lengths. The nylon outer sheath provides additional UV protection making it suitable for external applications where it may be subjected to sunlight. It also provides protection against the elements and some chemicals.

In temperature sensitive environments early detection of an abnormal change is crucial to protect safety of life, critical processes and reduce losses. The AA Analogue range of linear heat detection cable use exceptionally durable linear heat detection technologies which provide extensive and continuous coverage, is easy to install and fully integrate with building management systems. The products offer an enviable set of features bringing enchanced benefits and increased safety to the fire protection industry worldwide. 

The optional two stage programmable alarm settings make the system and method of overheat detection incresibly flexible and iseal for use in a variet of different environments and applications. The technology automatically compensates for changes in the ambient temperature to maintaion the accuracy of alarm temperature as well as offering up to 500 metres of continuous detection per control unit. Both versions of control unit carry UL521 approval. One is a self contained unit or, for finer control, a version requiring a PC prevents uninvited system access. Both designs are compatible with any conventional or addressable fire alarm panel or other building management system. 

This unique sensor cable and its method of control continuously responds to changes in temperature. The technology offers the facility to programme an early warning pre alarm as well as the specified alarm temperature. If the temperature surrounding the cable reaches the pre alarm point, the control unit triggers a warning giving the user time to survey the area at risk. Only when the temperature reaches the specified set alarm point will the control unit trigger full alarm. 

Analogue LHD cable is "self-restorable" which means it not always necessary to replace the cable after an incident. Once the alarm has been triggered and depending on the severity of the incident the system can simply be reset with munimum disruption and inconvenience.
