INSTALLATION
WARNING
•
The wall does not have any pronounced depressions or protrusions.
•
Install the detector on rigid surfaces, free of vibrations.
•
Avoid to fix the detectors near to heat sources or at direct sunlight.
•
Avoid electromagnetic energy reflection on wide surfaces such as mirrors, metal
walls, etc.
•
Avoid to fix the detector in front of fluorescent lamps or in proximity of them.
•
Connections shielded cable is suggested and one cable per detector is preferred.
•
Separate the alarm system cables from the mains cables.
The detector can be installed outdoors (according to the Class IV EN 50131-1).
•
Avoid to direct the detector towards moving objects or, if impossible, please take
care in adjusting the detector in order to avoid false alarms.
•
Be sure to install the cover with Fresnel lens before the detector testing. Without
cover, the detector doesn't work.

Placement
Environmental conditions are important elements to be evaluated during the
installation. Bump, bottomland or slops can modify the performances of the
detector.
If into the detection area any medium size animal can walk, it is suggested to
choose carefully the installation height in order to avoid false alarms.
Installation height must be between 1 m and 1.30 m (not tilted ground).
Note
The maximum coverage range, 18m, is reached when the detector is installed at
about 120cm (height).
Do not obscure partially or completely the detector’s field of view.
COVERAGE TESTS
Once the detector has been powered, wait 3-4 minutes before running the
coverage test (the IR sensors need to be stabilised).
In order to obtain a real simulation, free the protected area, preventing more
people from moving inside the same area.
After 30-40 seconds of quiet, try to access the detection area by moving
perpendicularly to the beams, thus avoiding a frontal approach.
Check the operation of the two PIRs with the two green LEDs and the operation of
the microwave with the yellow LED.
Run the operation test, making sure to break the IR beams (table 5 "Top view" e
table 6 "Side view") by moving perpendicularly to them.
Once detection has been achieved, wait for at least 7-8 seconds before trying to
be detected again.

Mounting
1.
Unscrew the screw for the cover enclosure (table 2, I).
2.
Remove the cover with lens (table 2, D).
3.
Set up for the steel bracket fixing (table 2, B) on the wall, or on a pole (be
sure the pole is stable and ripple free).
POLE FIXING
4.
Position the two “U” (table 2, A) shaped bracket around the pole.
