will see an alternate flashing of these, to stabilize
the system. Term of flashes you can proceed with
the following settings.
PIR RANGE (SENSITIVITY) 1-12m
REGULATION TRIMMER: Adjust the PIR
range through the trimmer, implementing with
crossing test. Submitting ORANGE LED will
help to verify the detection of the passage in
different areas (exp. 0m, 4m, 7m, 12m). Test the
goodness of the coverage of the affected areas, by
adjusting the MW.

5. ADDITIONAL FEATURES
OPEN FIELD FUNCTION
By applying a positive to TERMINAL 4 it will increase the microwave sensitivity for "a open field
applications"
In this way, the implemented algorithm takes advantage of the absence of walls and windows allowing the
adjustment at a great distance (12 meters).
N.B.: Usethis function only in case of installation "in the open field" (see example 2 on p. 10); perform
the microwave sensitivity settings by checking the maximum range.
EXPOSED AREA FUNCTION
Leaving DIPSWITCH 1 in position OFF, the sensor is set for an outdoor installation with no shelter (canopies,
arcade, …) and so directly exposed to strong atmospheric agents (rain, snow, …).
With this feature activated, the system if necessary self performs the function “ENVIRONMENTAL
COMPENSATION”, adjusting its own detecting parameters, avoiding false alarms.

IR ANTI-MASK FUNCTION
Turn the dipswitch number 2 for the functionality ANTI-MASK. Activating this function when an object is
placed in front of the sensor to blind it and make it ineffective, an active infrared system checks for the
presence of these in 3 seconds and gives an output signal through dedicated. The anti-mask microwave
verification of the presence of an object check in 20 seconds the presence of an object and gives an output
dedicated.
N.B.: If DIP 2 (anti-mask) and 4 (LED) are activated when it comes in a stealth mode, led blinking green-
orange alert the opening of the contact ANTI-MASK.
WARNING: When activated the DIP 2 before leaving the installation spot, you MUST close the sensor NAT
and you MUST power down and power up the entire system.

SECURITY FUNCTION
Turn on the dipswitch number 3 functionality SECURITY. Activating this function if the MW sensor provides
at least 7 distinct surveys in 30 seconds, the alarm signal from a system independently of the PIR sensor
readings. Dually the IR sensor provides at least 4 separate surveys in 30 seconds, the system by an alarm
signal regardless of the sensor readings MW.

6. DESCRIPTION OF NOT SETTABLE FUNCTION
PET IMMUNITY SYSTEM
The system of pet immunity is able to discriminate the small animals up to a maximum of 10kg and not to
give an alarm signal. In the case of animals such as dogs and cats perform function tests.
SELF-DIAGNOSIS SYSTEM
The system will periodically check every 50sec about the functionality of the microwave and PIR system. In
case of Malfunction of one of the two detection equipment, this is signaled by the flashing of the LED
dedicated (GREEN and ORANGE for MW for IR), steadily. In this condition the system excludes the
operation of the technology is not working and the detection will continue to be present in the OR mode.
AUTO-THERMAL SYSTEM
The system detects the temperature of the surrounding environment through a dedicated sensor and modify
the detection parameters of the IR sensor in order to adapt to extreme environmental conditions.
AUTO-ENVIRONMENTAL SYSTEM
The system locates in the case of heavy rains and snowfall an environmental condition "different" after about
20 seconds and is able to adapt the system to the detection threshold by changing the parameters of both
technologies for the duration of the event.

7. APPLICATION
The sensor can be commonly used for the protection of facades using the bracket to "L", and thanks to the new
system of AUTO-ENVIRONMENTAL is able to reduce to zero the possibility of "false alarms". The
installation MUST be carried out at height between 2 and 3m by adjusting the range and sensitivity of the two
technologies (MW + IR).

8.PIR LIMITER
If the NAT sensor is applied along a wall, it is possible that the PIR detects an area of none interest that can
generate more or less important reflections and false detections depending on the type of material present.
In order to obtain a more precise and safe area of detection it is possible to apply the PIR LIMITER supplied
which limits the angle of view of the sensor.
In this way, the sensor detects only interested area.
