Stratos-HSSD-2
®
  is  a  highly  sophisticated  ‘next  generation‘  of  High  Sensitivity 
Aspirating Smoke Detection product that has been designed to ensure that installation 
and commissioning is as simple as possible, while optimising performance.
Stratos  incorporates  a  patented  ‘artificial  intelligence‘  known  as  ClassiFire 
®
,  which 
allows  the  detector  to  configure  itself  to  optimum  sensitivity,  alarm  thresholds  and 
minimum nuisance alarms for any environment.
ClassiFire  intelligence  also  monitors  the  detector  chamber  and  dust  separator 
for  contamination,  continually  adjusting  the  appropriate  operating  parameters  to 
counteract the negative effects of such contamination.
Stratos is unique in being able to provide a consistent level of protection in a very wide 
range of environments by continuously making minor adjustments to sensitivity.
Stratos has proven its worth many times by detecting ‘difficult-to-detect‘ slow growth 
electrical overload incipient fires in ‘difficult‘ environments.
This  handbook  gives  information  likely  to  be  needed  for  most  installations,  but  for 
more detailed information on subjects such as
 
Fresh Air Referencing, please refer to the 
complete Technical Manual or System Design Guide.
This equipment is Class 111 as defined in EN60950 (i.e., this equipment is designed to
operate from Safety Extra Low Voltages and does not generate any hazardous voltages).
This label is located on the laser chamber at the bottom right of the open detector and 
signifies that the unit is a Class 1 Laser product as specified in IEC 60825-1. The unit 
incorporates a Class 3B embedded laser which must not be removed from the detector 
as retinal damage may result if the laser beam enters the eye.
As  this  equipment  is  part  of  a  fire  detection  system,  it  should  be  supplied  from  an 
approved power supply conforming to EN54-4.
This  symbol  appears  on  the  main  board  of  the  unit  and  indicates  that  the  board 
contains  static  sensitive  components.  Suitable  anti-static  precautions  must  be  taken 
when handling the board, eg. for fuse replacement.
This symbol indicates the Safety Earth studs (see  sections 1.3 and 1.4). These are for 
grounding cable screens etc. and should not be connected to 0V or signal earth.
Kidde Products Ltd. has taken every care to ensure that Stratos is as simple to install

when the option is selected, eg Setup menu.
Entries  shown  as  <EXAMPLE>  represent  function  buttons  on  the  front  of  the 
detector, eg. <TEST>.
