1. DESCRIPTION
EXPLORER II is a outdoor microwave barrier of extremely high reliability.
It houses up-to-date circuit technology in an aluminium casing which is
equippedwithaspecialplasticcoverbeingextremelyresistanttoatmospheric
agents. It is easy to mount on tubes in the wall or the ground.
EXPLORER II is able to discriminate and thus distinguish atmospheric
perturbationsandthefallofleavesfromattemptsatburglary.Thebarrieris
completelyimmunetofog.

flataspossible.
Bestresultsareobtainedonsurfacessuchascementedpavements,asphalt,
earth and on all homogeneous surfaces.
Goodresultscanalsobeobtainedongrassunlessitiskeptwell-trimmedand
does not exceed 10cm height.
Small trees and bushes can generate false alarms.
Small obstacles such as electric masts or wire-mesh fences with large
meshes (min. 5 x 5cm) which do not move donot affect the correct
functioning of the system.
2.2 PERIMETER PROTECTION
On every side of the perimeter is installed a receiver (RX) as well as a
transmitter(TX).
For the protection of a perimeter
composed of four sides (fig. 1), the
barriers have to be placed so that
two transmitters (TX) are placed in
everyangleandtworeceivers(RX)
inthe opposite angle.
This arrangement prevents from
possible interferences between
receivers and transmitters. If RX
and TX are installed close to
eachother,thesignalofTX,whichis
verystrong,candisturbthereceiver

In case of a triangular installation
using three barriers only (fig. 2), the
followingprecautionshavetobetaken
since in one angle a receiver has to
beinstallednexttoatransmitter:
+RX1 has to be placed at 10m
distance from the point of
intersection formed by the
radius of transmission of TX3
andTX1.
+TX3 has to be positioned at 6m
distance from the point of
intersection.
+The angle formed by RX1and
TX3should not exceed60°.
2.3 ANGLE POSITION
To ensure total coverage with two
beams crossing, it is essential to
respect the distances between the
axis of the tubes (fig. 3) as indicated
below:
+type 0600:
distance A1 = A = 3m
+type 1200:
distance A1 = A = 4m
+type 1800:
distance A1 = A = 5m
2.4 MOUNTING HEIGHT
In order to obtain best performance
of TX and RX, it is important to
respect the indicated perimeters
(fig. 4) as shown below:
+type 0600: H = 65cm
+type 1200: H = 90cm
+type 1800: H = 115cm

(fig.11), battery voltage test is
enabled.
Incaseofpowerfailure(18VAC

2.5 PROTECTION OF PERIMETERS SUPERIOR TO THE
DETECTIONRANGE (180 METERS)
If the perimeter to be protected is superior to the maximum detection
range of the barrier (max. 180m), a series of barriers have to be
positioned side by side (fig. 5).
The distance between the aligned barriers should not exceed 50cm in
order to avoid undetected intrusion via corridor "C".
Atransmittermust never beinstallednext toareveiverbut nexttoanother
transmitter in order to prevent from possible interferences.
The distance A (RX1 to RX2 or TX3 to TX2) has to be the following:
+type 0600: distance A = 6m
+type 1200: distance A = 8m
+type 1800: distance A = 10m
3. ALIGNMENT
3.1 ALIGNMENT BY DIGITAL VOLTMETER
Afterhavingpositionedthebarrierbyobservingpriorinstructions,makean
initial visual alignment. Insert the jumper J2 to exclude the automatic gain
control (fig. 7).
The green LED is
switched on and signals
thereceptionofthesignal
emittedbythetransmitter.
Should the LED not be
switched on, check the
position of the frequency
switches. Mesure the
tension on point A and B
onthetestconnector(fig.
8)withthehelpofadigital
voltmeter set in AC. If

it is recomended to change the position of the transmitterin the first place,
if the result should not be satisfactory try to move also the receiver.

9. TEST
9.1 ELECTRONICBOARDTEST
EXPLORER II is equipped with a test section which controls the correct
functioningoftheelectronicboard.Thestand-byinputofthereceiverboard
hasto be connected to the negative stand-byterminal of the control panel.
If the stand-by input is not connected, the test function is disabled. If the
controlpanelisinstand-by,negativevoltageispresentonthestand-byinput
ofthereceiverboard.Ifthecontrolpanelisarmed,negativevoltageismissing
on the stand-by input.
On the receiver board there are a stand-by input, two fault terminals which
correspondtothecontactsofanormallyclosedrelay(open=fault)andtwo
alarmterminalswhichcorrespondtothecontactsofanothernormallyclosed
relay (open = alarm).
If there is negative voltage on the stand-by input of the receiver board, the
barrier passes into test condition:

3.2 ALIGNMENTBYCATHODE-RAYOSCILLOSCOPE
Connecttheprobeofthecathode-rayoscilloscopetotestpointTP3(fig.8).
Adjust the time base of the cathode-ray
oscilloscopeaccordingtothemodulationchannel
used:
+Channel1=50µs/division(fig.8)
+Channel2=20µs/division(fig.9)
PositiontheswitchV/div on 1VAC.Amodulated
voltage appears with a period of:
+Channel 1 = 180 µs
+Channel 2 = 127 µs
Theminimumamplitudeacceptedis2.5Vpp,the
maximum signal of saturation is 4Vpp.
Search for the maximum amplitude on the cathode-ray oscilloscope. The
trace of the obtained signal has to be clear and without overmodulations.
If this is not the case, look for possible reasons (e.g. interferences with
anotherbarrier,highpowerradiotransmissions,largemetalliccarrierpipes
that may run underground, high voltage electric carrier pipes near by etc.)
In case the source of perturbation is a powerful field of radio frequency, it
is advisable to mount the barriers at 50cm height from the ground.

OF EXPLORER
Considerthatreplacingabarrieroftheprevious
versionbythenewone(EXPLORERII)the
transmission frequency has to be adjusted
accordingtothefollowingtable:
7. LED FUNCTIONS
TherearethreeLEDonthereceiverboard(fig.7).
The red alarm LED signals the status of the alarm relay:
» LED off relay closed (no alarm)
» LED on relay open (alarm)
The yellow alignment LED indicates the intensity of the signal received:
» LED off goodconnection
» LED on insufficient signal power (the barrier has to be aligned)
The green channel identification LED indicates if TX and RX are set on
the same transmission frequency:
» LED off TX and RX set on different frequencies
» LED on TX and RX set on the same frequency.

3.3 ALIGNMENTBYTECNOTESTER
Proceedas follows:
+PositiontheswitchoftheTECNOTESTERon"OFF".
+Insert the jumper J2 (fig. 7) to exclude the automatic gain control.
+Connectthe TECNOTESTERcable tothe jumperCN2. Keepan eye
on the correct sense!
+Align the barrier so as to obtain the maximum signal. The number of
LEDs lit indicates the quantity of signals received. The indication "+1"
stands for the minimum of signals acceptable.
+Once the alignment has been finished, remove the jumper J2 (fig. 7)
and position the switch of the TECNOTESTER on "ON". In case of
intrusion, a buzzer signal is activated.
VATTENTION W
Ifthereareno movementsatall,TECNOTESTERmust notindicatea
value inferior to +1.
4. NOISELEVELCONTROL
The oscilloscope measures the level of electrical noise on the receiver.
Proceedas follows:
+Disconnect the transmitter opposite to the receiver tested from mains.
+Put the oscilloscope probe on the test point TP3 (fig. 7).
+Settheoscilloscope at50mV/div.
+Readtheamplitude ofthe signal.
Best functionality is given with an amplitude lower than 300mVpp. In case
the noise level exceeds 500mVpp, the power supply (AC) has to be
disconnected and the electronic board has to be powered merely by
battery or power supply (13.8V DC).
Shouldthe noise levelreturn to its regularlevel, the problemlies with line
voltage (e.g. voltage filter). In this case check the relative device.
If, however, after disconnecting the power supply the noise level remains
superior to 500mVpp, call for technical assistance.
Assoon as adjustmenthas been completed,connect the automatic gain
control by removing the jumper J2 (fig. 7).
After approximately 10 seconds the barrier is ready for integration and
sensivityadjustment.

(sensivity) and PT6 (integration). In the beginning set the trimmer PT3 at
minimum sensitivity (turn anticlockwise) and the trimmer PT6 at maximum
integration(anticlockwise).

We recommend minimum integration of PT6 in order to avoid unwanted
