SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
Congratulations on having purchased the Politec perimeter barrier.This appliance guarantees
long-lasting and reliable operation if installed correctly.For correct and effective use, it is
necessary to read this instruction manual carefully.
The system has been designed to detect intrusions and activate the alarm; it is not a
device that prevents intrusion.Politec is not responsible for damage, injury or loss
caused by accidents, theft, force majeure (including momentary lightning-induced
overcurrent), abuse, improper or incorrect use, faulty installation or inadequate
maintenance.
2. Product description
The double optic infrared perimeter barrier consists of an infrared receiver and transmitter.
Operation is based on "AND" logical operations: in other words, the alarm is activated only in the
event of simultaneous interruption of two superimposed beams.
N.B.:These barriers use optical synchronism.The receiver must see ONLY and exclusively its
transmitter.MUST NOT see signals from other barriers, IR lights such as photocells or flashing
lights.It is not recommended for use in indoor applications where there are many reflections
and light sources
This barrier is ideal for perimeter protection of internal and external areas.
It is equipped with a system for selecting the operating frequency that allows you to install
multiple barriers on the same site without them interfering with each other.The main features of
this barrier are:
•Adjustable intervention time which allows you to adapt to the characteristics of the site to be
protected;
•Protection beam angle adjustment both vertically and horizontally;
•Set-up for mounting on a wall, on a pole and on aluminium columns;
•Optical alignment with viewfinder and signal measurement points;
•Contact signalling barrier opening.
Warnings
Mounting, installation of the barrier and connection to the mains must be carried out
by expert and qualified personnel, in compliance with rules and regulations applicable
to electrical systems.

SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
5.1 Preparation of the barrier parts before installation
Since the communication between the barriers can take place wired, via wireless and their alignment
can be done optically, it is advisable to firstly check all the component parts of the barriers and any
accessories before beginning the installation.
5.2 It is advisable to carry out:
•device configuration on a table;
•a check on the operation of the optical and acoustic alignment
•the permanent fixing of each device;
•the preparation and carrying out of electrical connections.
In order to avoid errors, operating and installation problems, it is advisable to proceed as follows:
a) Place all the products with the package open on a table;
b) For the low consumption barrier version for wireless models with universal circuit board housing,
insert and connect the radio transmitter, and connect it to the barrier receiver board
c) Power up the barriers and program them
d) Test barrier operation;
e) Place (without fixing) the barriers at the planned points;
f) Place (without fixing) all the other devices at the planned points;
g) Check for each barrier that there is sufficient field for radio communication (for wireless versions);
h) Permanently fix the barriers.
Before proceeding with the installation, it is necessary to check the integrity of the product, the
adequacy of the model chosen and the suitability of the environment intended for installation:
• Check that all conditions of use fall within the "limits of use" and in the "Technical specifications of
the product".
• Check that the environment chosen for the installation is compatible with the total footprint of the
product.
• Check that the surface chosen for the installation of the product is sturdy so as to ensure stable
fixing and that it is adequately protected against possible impacts or the elements.

6.1 Placement and installation height
Position the barrier considering the type of surrounding environment and the protection distance for
correct and effective operation.
Position it in such a way that there are no obstacles in its range of action (trees/plants or objects that
can swing or move with the wind or rain).
Position the barrier so that sunlight does not hit it directly near the RX sensors.
In any case, it is necessary to take into consideration the specific beam diffusion of each model, to
avoid reflection of the beams caused by the ground or by adjacent objects.

6.2 Placement and mounting
It is highly recommended to always request and use the accessory brackets for fixing the columns,
avoiding to drill the aluminium structure.
Pole mounting with SAN/PL
SAN/PL brackets allow fixing on poles type
SAN/TB1 and SAN/TB2 with a diameter of 48 -
50mm in a very simple way as seen in the figure.
•Each column requires a minimum of 2
brackets or more if the column is very tall.
•The poles are equipped with a base for fixing
to the floor or to the POB30 cable pit to be
cemented into the ground, also with the
function of branch junction box.
•The connection cables enter from the lower
cover of the column, equipped with O rings
and cable glands.
Wall mounting with SAN/SD
The SAN/SD brackets supplied in akit of 2
pieces allow wall mounting and are invisible, as
seen in the figure.
•These brackets are recommended when the
columns are placed in front of each other or
the internal optics are rotated to less than
90° horizontally.
•Each column requires a kit consisting of two
brackets, which are fixed to the ends of the
column, leaving only the holes for wall fixing
visible.
•Once all the installation and functional
operations have been completed, the two
covers will hide the part with the fixing
holes.
Wall mounting with SAN/PL
The SAN/PL brackets also allow fixing to the
wall, in a very simple way as seen in the figure.
•It is recommended to use these, when
protecting windows, doors, etc., along the
wall, in order to avoid small obstacles, such
as hinges, edges of the windowsills, which
could be in the beams creating an
attenuation of the signal.
•Each column requires a minimum of 2
brackets or more if the column is very tall.
WARNING:
Product warranty is invalid if there is any hole in the aluminium profile or any component

7.Evaluations before installation

SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
7.1 Introduction to barriers
The Active Infrared Barrier is characterised by two components, a TX transmitter that emits a pulsed
infrared signal towards the RX receiver.This signal is constantly controlled by a CODED SYNCHRONISM
which can be WIRED or OPTICAL according to the different types of barriers.
The transmitted infrared beam takes on a conical shape: the greater the distance between TX and RX,
the greater the diameter of the cone when it arrives.
View from above
TX RX
N.B.All the optics of this barrier are already equipped with heaters, however it is possible to
mount the optional SANDOR TS thermostat control kit which allows it to switch on and off at
the preset temperature.

50 m
2 m
TX
Signal interruption:ALARM
A barrier can be composed of several TX transmitters and RX receivers mounted inside specific
different columns.
The infrared barriers have multiple controls that significantly limit false alarms, as the genuine
alarm signal is given by the complete interruption of the infrared signal.
HEATERS
It is recommended to power the thermostating system as, in conditions of high humidity, the
condensation that is created on the screen can lead to a significant decrease in the IR signal up to the
alarm.For obvious reasons, for battery powered barriers, there is no thermostat control even if set
up, therefore to minimise the problem, it is necessary to reduce the working distance between TX
and RX, thereby ensuring a good amount of signal constantly, even in case of particular climatic
conditions.
POWER SUPPLY
The barriers can be divided into two categories, powered at low voltage and connected by wire, or
powered by batteries for Wireless systems, then combined with radio transmitters to communicate
with the alarm control unit, as required by specific sector regulations.

8.Barrier positioning
10
SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
8.1 Precautions before installation
In order to avoid false alarms, it is advisable to place the barriers away from reflecting surfaces, away
from walls or anything that can attenuate the signal.
DO NOT place the barriers if there are plants, bushes or fixed objects in the range that obstruct
the signal and create "grey areas".Leave a corridor of 50cm for distances between columns
greater than 50m
TX RX
TX RX
DO NOT place barriers close to roads: vehicle lights directed towards the RX could create
disturbances
DO NOT place barriers near automatic gates: photocell signals can create interference.
RX
DO NOT place the barriers close to walls, without spacing the columns with adequate brackets, as
the signal quality may decrease

SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.0
9.1 Barrier positioning
In addition to standard products, all Politec products can be customised according to the installation
needs including height of the columns, number of beams inside and the different ways they are
arranged.
This barrier, always composed of aTX column and an RX column, lends itself well to single barrier
systems and for the protection of facades, as well as in the open field, observing the necessary
precautions, given by their characteristics (e.g. optical synchronism, power supply and working
distances).
To avoid interference between barriers, position the columns so that each receiver only sees its
transmitter.
N.B.:Use this layout also for barriers on facades on surfaces at different heights

10.Wiring
12
SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
10.1 Type of cable
Wiring requires you to SEPARATE the SHIELDED cable of the 12Vdc power supply plus all the signals to
the control unit (e.g.2x0.50 +Nx0.22), from the power cable of the 24Vac heaters (e.g.2x0.75)to
prevent the input of alternating voltage disturbances on the barrier.
N.B. it is absolutely necessary to shield the cable that supplies the 12 Vdc power supply and to
ground the metal braid.
The sizing of the cables depends on the consumption of the columns and on the resistance of the
cable itself according to the distances involved.
The table shows the cable cross-sections and the relative distances to ensure optimum performance
using the LAR22 power supply (12Vdc-2.5A/24Vac-300W) and a SANDOR DUAL SMA column.
The LAR22 can power up to 8 columns.The LAR22 container is metallic, so it must be placed inside a
room or put in a watertight container if used outdoors.A battery up to 18Ah can be housed in the
container.
Alternatively, the LAR18 power supply (12Vdc-0.9A / 24Vac-60W) can be used to power a single
barrier (pair).The power supply is kept in a PVC container and can offer IP68 protection if the junction
boxes are made with suitable products available on the market.The LAR18 can be combined with the
LARB4 battery housed in a PVC container like the LAR18 but not with the same IP rating.

It is recommended to make a star-shaped connection to avoid excessive voltage drops on the
power cables
The various examples shown here highlight the connection from the power supply to single
columns, however it can also be carried out in cascade when two columns have been fixed on the
same pole, having duly calculated: the distance, cable cross-section and consumption.

12.Barrier alignment
16
SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
For correct alignment, once the barriers are installed, orient the optical units of the transmitters and
the optical units of the receivers towards each other, adjusting the lens holder horizontally manually,
after having loosened the locking screw on the joint and vertically through the front screw located to
the left of the lens.
Vertical orientation Horizontal orientation
JOINT LOCKING
SCREW
N.B.:Tighten the joint locking screw after the adjustment
12.1 Calibration using SMA system
It is possible to improve the calibration by using the supplied filter.
1. Fold the device
following the pre-set
folds.
2. Position the filter in
front of the TX optic
inserting the two
hooks on the pins of
the optic fork.The
filter is designed to
refine the search for
the alignment signal
under adverse
conditions.
It is sufficient to apply the filter only on the TX, there is no need to repeat the operation also on the
RX.

12.2 Alignment
•Power the unit electrically
•Starting from the Receiving column, press the TEST button on the first RX optic for 3 seconds or
until the buzzer emits an intermittent acoustic signal, accompanied by the equally intermittent
flashing of the long-range high-intensity LEDs.
•Press the TEST button on the TX optic of the corresponding column for 5 seconds, in this case only
the orange TEST LED will light up.
•Orient the TX optic towards the RX optic, vertically and horizontally acting as explained above,
until you find the maximum alignment.
•The maximum alignment condition will be reached when the high-intensity LEDs are on steady
and the buzzer will emit a continuous sound, for this reason, it may be necessary to make minor
adjustments also on the RX optic.
TX RX
TX RX

18
SANDOR DUAL SMA POLITEC | INSTALLATION MANUAL - VER.3.1
N.B.: the fixed buzzer sound has a maximum duration of 3 minutes.To obtain a good alignment it is
necessary to complete a FULL rotation on the horizontal axis of the RECEIVER optic, thereby
performing the SCANNING of the optical signal.This operation is very useful to understand if the
alignment of the optics is taking place directly on the same axis and not through reflection, therefore
deceptive, because the signal value is much lower, despite having reached the hypothetical maximum
alignment signal.
•The partial or total misalignment condition is signalled by the infrequent flashing of the LEDs and
by the non-continuous whistle of the buzzer.
•After calibration, tighten the horizontal adjustment screw, and exit the test function by pressing
the TEST button on the TX and RX optics for 3 seconds.
•Repeat everything on the second beam of the barrier.
At the end of the operation, remove the screen which acts as an attenuator, making sure to have
found the optimal value.
N.B.:Optical synchronism requires greater attention
during the installation phases, in particular, that the
receiving column is not affected by other sources of
IR light.
To be absolutely certain that the alignment of the
optics is correct (and therefore no false alignments
due to the transmission of other infrared sources,
such as other barriers of the same system as well as
gate photocells) cover the TRANSMITTER optic with
your hand: if the RECEIVER continues to give a
continuous beep, it means that it sees another
infrared source that must be turned off and
eliminated.

Test the TX1and RX1 optics and proceed with the calibration as explained above but, having found
the maximum alignment, keep the TX1 optic in test and exit the test only with RX1, then repeat the
same operations with RX2.
At the end, exit the TX 1 test and repeat the operation with the TX2 optic on RX1and RX2.
At the end of all operations, make sure that TX1and TX2 are still optimally aligned with the
corresponding RX1and RX2.
WARNING: too close a distance between
the TX and RX columns does not allow
calibration with the crossing function.
Furthermore, this function significantly
increases sensitivity and is used to
intercept the approach to the barrier, not
the crossing.For this reason, it is
recommended to use this function only in
INDOOR applications
