Overview
The AASN series is an analogue Linear Heat Detection cable in a
Nylon outer sheath with a Stainless Steel brad, supplied in 100m
and 500m lengths. Similar in character to the standard Nylon
LHD sensor cable, the stainless steel braid provides additional
mechanical protection for cables which could possibly suffer
physical damage.
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 enhanced benefits and increased safety to the
fire protection industry worldwide.
Fast Response Time
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.
The Controller
The optional two stage programmable alarm settings make the
system and method of overheat detection incredibly flexible and
ideal for use in a variety of different environments and applications.
The technology automatically compensates for changes in
the ambient temperature to maintain 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.
Rest and Reuse
Analogue LHD cable is ‘self-restorable’ which means it is 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 rest with minimum
disruption and inconvenience.
