Scenario “9” : AND with 2 technologies Filter
Selecting this scenario will produce an alarm if at least two of barriers of different technologies,
regardless to the sequence (priority), detect an alarm condition.
MW and then Low IR, or Middle IR, or High IR, or disqualification Alarm
Doppler and then Low IR, or Middle IR, or High IR, or disqualification Alarm
IR Low and then MW, or Doppler Alarm
IR Middle and then MW, or Doppler Alarm
IR High and then MW, or Doppler Alarm
Disqualification and then MW, or Doppler, Alarm
MW and then Doppler No Alarm
Doppler and then MW No Alarm
IR (Low, Middle, High) and then Low IR, or Middle IR, or High IR No Alarm
This scenario will filter alarms created by the IR barriers when, for example, two of them, just
before to go into disqualification, produce the alarm condition.
Scenario “A” : AND with Priority Filter
Selecting this scenario will produce an alarm if at least two of barriers detects an alarm
condition, or one pair of barriers of different technologies reach alarm with the following
sequence: first MW or Doppler and then IR
MW and then Low IR or Middle IR or High IR, or disqualification Alarm
Doppler and then Low IR or Middle IR or High IR, or disqualification Alarm
IR (Low, Middle, High) and then Low IR, or Middle IR, or High IR, or disqualification Alarm
Disqualification and then MW, or Doppler, or Low IR or Middle IR or High IR Alarm
IR Low and then MW, or Doppler No Alarm
IR Middle and then MW, or Doppler No Alarm
IR High and then MW, or Doppler No Alarm
This scenario will filter alarms when interference is present on the MW.
Scenario “B” : AND
Selecting this scenario will produce an alarm if at least two of barriers regardless to the
technologies, and regardless to the sequence (priority), detect an alarm condition.
MW and then Low IR or Middle IR or High IR or disqualification Alarm
Doppler and then Low IR or Middle IR or High IR or disqualification Alarm
IR Low and then MW, or Doppler, or Middle IR, or High IR or disqualification Alarm
IR Middle and then MW, or Doppler, or Low IR, or High IR or disqualification Alarm
IR High and then MW, or Doppler, or Low IR, or Middle IR or disqualification Alarm
Disqualification and then MW, or Doppler, or Low IR, or Middle IR, or High IR Alarm
Scenario “C” : AND with Anti-climb
Selecting this option will produce an alarm if at least one MW barrier pair and the middle IR or
MW and low IR, D IR Low, D IR Medium reach alarm conditions or if only the
top IR (anti-climb) reaches alarm condition.
MW and then Low IR, or Middle IR, or High IR, or disqualification Alarm
Doppler and then Low IR, or Middle IR, or High IR, or disqualification Alarm
IR Low and then MW, or Doppler, or Middle IR, or High IR, or disqualification Alarm
IR Middle and then MW, or Doppler, or Low IR, or High IR, or disqualification Alarm
IR High Alarm
Disqualification and then MW, or Doppler, or Low IR, or Middle IR, or High IR Alarm
This scenario allows an increased probability of detection in positions where it may be possible
to elude the detection by climbing.
Note: middle IR is optional.
