Position the function switch
SW1 on position 8
and it is possible to read and/or modify the
Barrier Number.
Modification
of the barrier number:
Select a number from 1 to 99 on the switches
SW2
(tens) and
SW3
(units).
Push
S1
, to confirm the acquisition and to start using the number set.
Read
the assigned barrier number:
Rotate SW2 until the green led (D6) is on,
Rotate SW3 until the green led (D5) is on.
The number from 01 to 99 represented by SW2 (tens) and SW3 (units) corresponds to the
barrier number actually in use.

After completing the IR alignment phase (described in the next section) it is possible to
select the operating scenario most suitable to the requirements of the site to be protected.
The choice of scenario is made using switch SW1 and selecting one of the following
positions:
“9”, “A”, “B”, “C”, “D”, “E”, “F”, “0”.
The scenarios are as follows:
Scenario “0” : AND with 2 techno priority Filters
Selecting this option will produce an alarm only if at least 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

Doppler
and then
Low IR, or Middle IR, or High IR, or disqualification

No Alarm

and then

and then

and then

and then

No Alarm
The use of this scenario allows to reduce drastically false alarms due to the reaction of the
different technologies used in critical environmental conditions, such as heavy fogs or rain,
narrow corridors and closed and loosen fences. The consequent reduction in probability of
detection must be always evaluated for the specific site requirements.
Note:
middle IR is optional.
