                  For the Engineer:
 Environmental flexibility: Orbis has a 
                  voltage range of 8.5 to 33V, an operating temperature of –40°C 
                  to +70°C and a tolerance of 98% relative humidity.
 
                  Unrestriced choice of panel as polarity reversal for 
                  200mS will not affect detectors. 
                  Ease of commissioning with 
                  
                  StartUp. 
                  Detectors flash (red 1x/sec) to show correct installation — 
                  detectors revert to normal operation automatically after 4 
                  minutes. 
                  Efficient maintenance procedure with 
                  FasTest®. 
                  FasTest takes just four seconds to test and confirm that smoke 
                  and heat detectors are functioning correctly. For 
                  the Installer: 
                  Fast and easy base installation with the 
                  
                  TimeSaver®
                  Base: 
                  
                  fit screws to 
                  mounting box or surface, place the base over the screws and 
                  slide into place using the 
                  E-Z Fit slots, then tighten 
                  the screws.
 Fast cable termination: the base has an open working 
                  area, single quadrant terminals, 
                  captive screws, a guide to cable stripping and detector LED 
                  alignment. 
                  Simplified stockholding. The Orbis base is compatible 
                  with existing mounting boxes and backplates. Ease of testing with the
                  Continuity Link which enables voltage testing of zone wiring prior to 
                  commissioning.
 
                    
                      | For the 
                      Owner: 
 Visually pleasing, harmonious design. Orbis has 
                      entirely new styling and combines a modern look and 
                      enhanced ease of use.
 
 Factory-set performance maintained with
                      
                      
                      DirtAlert™: 
                      A yellow flashing LED indicates that the drift 
                      compensation level has been reached.
 |  |  Contamination unlikely anyway with the
                  DustDefy system which 
                  prevents dust ingress while maintaining airflow. False alarms are reduced with
                  Transient Rejection 
                  which filters out transient high readings that might otherwise 
                  cause a false alarm. 
                  Features will vary according to territory. |
