Fig.1.1. Detection zone
L- Length of a sector h- Height of detection zone b- Width of detection zone
1.2.3. In Fig.1.1 and Table 1.1 the height (h) and the width (b) of the detection zone
are given for the middle of the sector. Moving towards the receiver or transmitter these
dimensions decrease evenly, given the geometry of positioning the receiver and transmitter.
1.2.4. The recommended distance from the axis of the detection zone up to fences,
building walls and other motionless objects at the sector length:
80…200m - 1, 1 m minimum
25…80m - 0, 8 m minimum
10…25m - 0, 4 m minimum
1.2.5. The sensor generates an alarm when:
-an intruder crosses the detection zone. Detection probability is 98 % when an
intruder crosses the detection zone at his “full height” or “bent”;
-external electromagnetic field influences on Rx for its masking. There may be
no alarm signal, but in this case the sensor should save its operability.
An alarm is generated by breaking the contacts of optoelectronic individual point relay
(standby mode) for 3 sec minimum. Orange and brown wires marked «NC» (normally
closed) and this alarm is transmitted over RS-485 interface.
Note. At the distance of 3-5 m from the supports with Tx and Rx the probability of the
intruder’s detection, who is moving stooping down (crawling through) in the detection
zone, is less than 98 % as an intruder can stoop down and pass below the detection zone.
1.2.6. The sensor generates a fault signal at:
- the absence of Tx signal;
- the absence of supply voltage or at its reduction lower than 8 mV;
- Rx or Tx failure.
When a fault signal is generated, the individual point relay contacts are broken, and a
fault signal is transmitted over RS-485 interface up to the malfunction repair.
1.2.7. When the exchange is interrupted over RS-485 interface, a fault signal is
generated by the alarm complex.
1.2.8. The sensor generates an alarm at the opening of Rx cover, under which there are
adjusters. The contacts of the tamper button (TAMPER) are open at the cover opening. This
alarm is transmitted to Rx by the separate pair of cables.
1.2.9. The sensor doesn’t generate false alarms at:
- rain, snow, thick fog;
- solar radiation;
- wind speed up to 30 m/sec;
- objects moving with the linear dimensions up to 0,2 m (birds or small animals);
- irregularities up to ± 0,3 m;
FORTEZA JSC FORTEZA FMC 24 (50m, 100m, 200m)

- snow up to 0,5 m (without additional adjustment);
- grass up to 0,3 m;
- the influence of ultra-short waves emissions of the range 150-175 MHz and the
power up to 40 W at the distance 6 m maximum.
1.2.10. The sensor is immune to electromagnetic interferences (voltage impulses in
supply circuits, breaks of mains supply, electrostatic discharges and electromagnetic fields).
1.2.11. The case of the sensor is made of impact-resistant plastic immune to UV
radiation and the temperature changes in all the performance range.
1.2.12. The sensor mean lifetime is 8 years.
1.2.13. Maximum dimensions of the units without a mounting kit, mm:

Package.
The protocol converter USB/RS-485 with the port isolation cable for PC connection
USB2.0 A –miniB are supplied at the customer order.
1.4. Operation principle
1.4.1. The sensor is a bistatic microwave device.
The sensor principle of operation is to generate an electromagnetic field between Tx
and Rx. This field forms a volumetric detection zone in the form of a long ellipsoid of
rotation. The sensor registers changes of the field when an intruder crosses a protected area.
1.4.2. An intruder crossing the detection zone causes some changes of the signal
amplitude in Rx. The signal passes through the amplifier and is compared with the thresholds
value according to the algorithm. If the signal change on Rx input is provoked by a person
passage, then Rx generates an alarm, breaking actuating relay contacts. The signal changes
FORTEZA JSC FORTEZA FMC 24 (50m, 100m, 200m)
Please visit our internet sites: www.forteza.com or www.forteza.eu Page 7
depend on: height and weight of the intruder, place of the sector crossing, its relief and speed
of the movement.
1.4.3. The signal on Rx input can be changed under the influence of other interference
factors: precipitations, vegetations, small animals, electromagnetic interference, swinging of
tree branches or gates, crossing the detection zone and which are commensurable with
intruder movements.
Other reasons, e.g. location of extensive constructions in the detection zone or near it
(fences, walls), irregularities and snow can influence on the Rx input signal. In these cases
the detection zone form is distorted because of re-reflections and interferences.
Multi thresholds operation algorithm permits to reduce the number of false alarms.
That’s why one should observe the recommendations of the subsection 2.1.
1.4.4. The alarms reception and indication are performed with the security system
controlled by the relay contacts, and with the security systems operating with RS-485
interface. When an alarm is generated, the normally closed contacts are broken.
1.4.5. You can use laptop to adjust and control the sensor operation. The remote
adjustment is also possible; you can control the sensor with the alarm complex over RS-485
interface.
1.5. Sensor structure
1.5.1. The detector consists of separate units (Rx, Tx) placed in dust-, splash-proof
enclosures.
1.5.2. Rx Construction and its fastening elements to the support are given in fig. 1.2
The carrier of the unit is base 4. Radio transparent enclosure 5 is fixed to the base with fixing
elements. In the heel of the enclosure there are two holes preventing condensed fluid
accumulation within the unit. The access to the controls, adjustment, indication elements and
clamps for the connection of the terminal element is open when the cover 6 is removed. Rx
is connected to the alarm control device with eight wires cable 8. Rx is mounted on the
support 1 using the bracket 2 and two buckles 13. Mounting provides the rotation of the unit
horizontally at angle +65minimum; vertically: upward - at angle 30minimum, downward
–at angle 45minimum (if the bolt 12 is eased). Location and marking of the clamps,
controls, and adjustment and indication elements located under the cover 6 are shown in fig.
1.3(a).
1.5.3. Tx construction and its bracket are the same as the Rx construction (see fig.
1.2). The difference is in internal elements: under cover 6 are shown in fig. 1.3 (b); six wires
cables are used instead of cable 8.
1.5.4.Mounting kit includes two brackets and four buckles for the mounting on the
support of Rx and Tx.

Note. Dear user! The manufacturer of the detector constantly upgrades their quality and
reliability. That’s why in some lots of detectors one can find design modifications
unspecified in the documents delivered with the detectors. Nevertheless, the main
specifications are valid.
1.6. Adjustment, control and indication parts
1.6.1. The micro channels switches provided the frequency channels switch are set on
the transmitter and the receiver. Only one of four switches can be set with the same number
on the receiving and the transmitting side when the power supply is ON.
CAUTION! Set the frequency channels only when the power supply is OFF!
FORTEZA JSC FORTEZA FMC 24 (50m, 100m, 200m)

If you switch a frequency channels on the operating sensor, the channels is not
changed, but after the power supply is switched ON/OFF the channels number is
changed.
1.6.2. The adjustment, the control and the sensor indication is performed by the
controls of the receiver LED indication and BUZZER sound, software FORTEZA FMC
oftware on PC.
1.6.3. Manual adjustment: calibration of detector signal using LED indication and
Buzzer; Sensitivity adjustment.
1.6.4. Adjustment using PC: calibration visualization; selection of detection zone
length; AUTO or MANUAL sensitivity adjustment modes.
1.6.5. To prevent unauthorized openings of the cover 6 (fig.1.2), a tamper button 2 is
placed in the receiver (fig.1.3). The button contacts are closed in the operating state. When
the cover is opened, the contacts are broken providing the circuit opening TAMPER.
2. INSTALLATION AND ADJUSTMENT PROCEDURE
The preparation to the sensor operation is the following:
- preparation of the sector;
- signal cables and power supply laying;
- Tx and Rx installation;
- sensor connection (connection of power supply and intruder alarm loops);
- alignment of Tx and Rx antennas
- Rx thresholds setting.
The principles and methods of these steps are given in i. 2.1-2.8.
2.1. Requirements for the protected sector of Rx and Tx alignment
2.1.1. The sector where Tx and Rx are located should meet the following
requirements:
a) The height of irregularities should not exceed +0,3m. If irregularities of the sector
surface from the plane exceed +0,3m, the specifications of the detector can worsen. In this
case the issue of the use of the detector under these conditions is defined by the trial
operation.
b) The height of the grass should not exceed 0,3m;
c) The height of the snow should not exceed 0,5m;
d) The maximum incline of the sector is 45˚;
e) Single fixed objects (e.g. posts, trees without lower branches) can be situated in the
detection zone at the distance of 0,5 m minimum from the axis;
f) The width of the sector should meet item 3.3.
FORTEZA JSC FORTEZA FMC 24 (50m, 100m, 200m)
Please visit our internet sites: www.forteza.com or www.forteza.eu Page 11
2.1.2. The detector can be mounted if the width of the sector is less. In this case if
“Calibration mode” voltage is less than 10 mV, it is necessary to change Rx and Tx position
relative to the support. For example, if Rx and Tx are at the left from the support, turning the
wall bracket relative to the support at 180º, fix Rx and Tx at the right from the support. If it
is not successful and “Calibration mode” voltage is less than 10 mV, it is necessary to realize
the trial operation and according to its results to make a decision about the possibilities of the
detector operation in these conditions.
2.1.3. Moving objects influenced by wind: wings of gate, bushes, trees branches, etc.
should not be situated in the detection zone and at the distance of:
± 1,7 m from the axis connected Rx and Tx at the perimeter length from 10 to 50 m;
± 2,2 m from the axis connected Rx and Tx at the perimeter length from 50 to 100 m;
± 2,6 m from the axis connected Rx and Tx at the perimeter length from 100 to 200 m.
2.1.4. Sector width should not be less than the detection zone one (see Table 1.1).
The sensor can be mounted if the sector width is less. In this case the sensor application is
determined by trial operation.
2.1.5. The range of the sector’s slope is 40˚ maximum.
2.1.6. The sensors with different channels should be mounted on the neighbor sectors.
When the sensor is mounted one after another on the sectors, a number of the channels
should be repeated successively from 1 to 4 providing the maximum distance of the sensors
with the same letter.
2.1.7. To increase the detection zone in the height, it is possible to align the sensors in
two tiers. The sensors should have different channels; two transmitters should be installed
from one side of the protected area, two receivers –from another one. The sectors lengths
should be identical.
2.1.9. The sensor can limit the maximum intruder’s speed. If the maximum intruder’s
speed is reduced, the interference immunity will be increased. The manufacture produces the
sensors with the maximum intruder’s speed of 10 m/sec (“high”). You can reduce the
maximum intruder’s speed up to 4 m/sec (“middle”) and up to 1 m/sec (“low”)*. You can
change the intruder’s speed with PC. After that it is necessary to set the alarm sensetivity
again.
e.g. open perimeter area –high intruder’s speed; the zone between a fence and an
auxiliary one (an intruder can’t rush) – middle intruder’s speed; sensor mounting on the
top of the fence –low intruder’s speed.
2.2. TX and RX mounting
2.2.1. Mark the perimeter area for the places where the supports will be mounted. To
generate a continuous protected boundary, the installation of Tx and Rx isn’t permitted on
adjacent perimeter sectors. The right installation on adjacent perimeter sectors is Tx and Tx,
Rx and Rx. To generate the continuous protected boundary, it is necessary to provide the
FORTEZA JSC FORTEZA FMC 24 (50m, 100m, 200m)

overlapping of the sectors detection zones (see fig. 2.1 and 2.2). The overlapping is
necessary to eliminate the possibility of the sector overcoming under or above Tx (Rx)
unit near the support.
Fig. 2.1
Fig. 2.2
Note: To avoid co-interference between neighboring detectors, you can adjust them
to different operation channels (don’t forget to change receiver’s and transmitter’s
operation channels too with the mentioned way in the manual).
Note: Avoid installation in a way where the reflected microwave signals (by metal
fences and other metal objects or by wet surfaces after rain and snow) may cause
interference and false alarms.
2.2.2. Mount the supports. It is recommended to use metal or asbestos-cement tube as
supports of 70…90 mm diameter. The height of the support above the surface of the ground
is given in fig. 2.3. In the places where there is a lot of snow, the superstructure of the
support should be 1500 mm minimum. As for the support construction, it is necessary to
provide some dowels for concreting and some holes for the cable gland. The example of the

2.2.4. Lay the main cables according to the project of the security system. It is
recommended to use multicore cables with the core screen or metal sheath. The cable core
section is chosen on condition that the supply voltage is not less than 9 V for every sensor
unit. It is not recommended to lay the main cables near heavy electromagnetic interference
sources (power lines, antenna systems, and etc.) and to use free cable cores for impulse
signal transmission. CAUTION! To reduce the level of electromagnetic interferences, it
is recommended to mount the power supply unit at a distance up to 300 m from the
place where the sensors are installed.
2.2.5. The mounting kit (MK) for mounting on the top of the fence can be delivered on
the customer order to protect the perimeter site from the intruder climbing over the fence and
the intrusion into the window. The example of the sensor installation with the brackets
application 350, 500 mm is given in fig. 2.4. The detection zone sizes are shown in Table
2.1. The angles to turn horizontally the sensor units on the brackets are 180˚, vertically: up –
at the angle of 17˚, down - 45˚.

Notes.
1. If the upper part of the fence is protected with physical protection devices, it is necessary
to use the bracket of 500 mm. If the upper part of the fence is not protected with barbed
wire, it is recommended to use the bracket of 350 mm.
2. The height of Rx and Tx units for the protection of the fence upper part is equal to the
fence height ±100 mm.
3. The dimensions and materials of the fence are not specified. It is necessary to provide
the fence rigidity.
4. The detection zone dimensions b and h are given for the correct alignment of the sensor
according to i. 2.4, 2.5.
5.To avoid co-interference between neighboring detectors, you can adjust them to different
operation channels (don’t forget to change receiver’s and transmitter’s operation
channels too with the mentioned way in the manual).
6.Avoid installation in a way where the reflected microwave signals (by metal fences and
other metal objects or by wet surfaces after rain and snow) may cause interference and
false alarms.

Warning: Do not open the detector’s housing, because it may damage the device!!!
Note: Always use separated cables for the power supply circuit as the cables for the
alarm signal circuit to avoid unexpected alarms.
Note: The alarm contact loading capacity is up to 30 Vdc 0.1 A.
Note: All the electronic connections should be carried out only after power is
disconnected.
2.3.3. The type and the nominal of the terminal element of the security systems loop
(resistor, condenser and diode) are determined by the type of the control device. The detector
is connected to the control device. Usually it is a resistor. The nominal resistance of this
resistor should take into the clamping resistor of the lightning circuit (this resistor - 100
Ohm) and resistance of the security systems loop (depends on the chosen cable type and its
length).
2.3.4. The contacts of the tamper circuit (“TAMPER”) of Rx or Tx can be connected
to the receiver control device by the separate loop. In this case the user receives the
information of the opening of the Rx or Tx terminal covers with the separate signal. The
second variant: the individual point relay is switched ON in series with the contacts of the
individual relay. In this case an alarm will be generated when:
-the individual point relay functions;
-the opening of the Rx or Tx terminal covers on one channel of the control device.
2.4. Sensor adjustment with the built-in adjustment, control and indication parts

out or lights up-determine the problem and correct it using table 4.1
2.4.2.6. Aligning is performed incrementally and consists of a set of repetitive actions.
The alignment can be started with both transmitter or receiver. In the alignment mode, the
detector switch, when you press and hold down the button, "AGC" on receiver. The indicator

“LED” and BUZZER is switched ON.
2.4.2.7. Tx and Rx are adjusted on the angle of the place and the azimuth according to
the buzzer signals and “LED” blinking’s (on the RX). Two persons are necessary for the
detection zone calibration. One of them is situated next to Rx, the other –next to Tx.
The alignment includes the following order:
a) Loosen the bolts 12 (see fig. 6.1) of Rx; Loosen the nuts 10;
b) Press and hold the button “AGC” on Rx. Rotate Rx horizontally, seeking the
maximum signal, then rotate the Rx vertically, seeking the maximum signal (the
most frequent LED indicator flashes/beeps). Release the „AGC“ button.
Repeat the paragraph b) If during the repeat of paragraph b), rotating the unit vertically the
flashing of LED indicator slows down the adjustment will be complete. Otherwise one more
time repeat articles in the following sequence a) and b).
c) Tighten the bolts 12;
d) Tighten the nuts 10;
Check the buzzer signal speed and “LED” blinking’s as a result of the adjustment.
Rx and Tx must directly at each other for stable operation. Don’t misalign Rx and Tx
down or a side.
2.4.2.8. After commencing the adjustment, wait for the sensor to switch in to working
mode (1-2 minutes), the LED should go out.
2.4.2.9.Complete the described actions for the Tx, controlling the signal level
according to the indicator of Rx. For coordination of actions use the talk set.
2.4.2.10. If the LED shines and rarely turns out - the calibration signal voltage is in the
upper critical point of the allowed diapason - a) the increasing of distance is needed between
Rx and Tx or b) disalig the sensors by turning them up. If the LED rarely flashes - the power
of the signal is in the lower point of the allowed diapason - it is needed to lower the distance
between Rx and Tx or change (with 4-5 cm interval) the placement of Rx or Tx from the
ground down or up.
2.4.3. Sensitivity setting
2.4.3.1. Standard switches SENS in the position PC this means that sensitivity is
set from computer. You can change the sensitivity +10% or -10% percent’s using switches
if it necessary.
2.4.3.2. Sensitivity is adjusted according to the protected sector crossing at the “full
height” or “bent” (crawling) along its whole length. It is recommended to begin doing these
check passages in the middle of the protected area. It is necessary to go out of the detection
zone at a distance of 1-2 m and to pause from 5 to 7 sec. Otherwise, the results of the
previous passage will influence on the next one.
2.4.3.3. When the sensor generates alarms, “LED” indicator shines for 3 sec. After the
switching ON of the indicator “LED”, the following passage can be done.

2.4.3.4. Do some check passages in “problem” places of the detection zone: hollows,
hills, near to barriers, buildings, and trees situated in the detection zone. If it is necessary
change the sensor sensitivity.
2.4.3.5. We offer to set switchers in position –10% and cross the detection zone
in different points. In case if the detector is not generated alarm during the investigator
passage, set first switchers to position and after that to position + 10% .
Notes. If switcher’s is in position + 10% the detector is not generated alarm during
the investigator passage, please use computer to adjust the sensitivity.
2.4.3.6. When the adjustment is over, it is necessary to close Rx and Tx terminal
covers.
2.4.3.7. After the sensor adjustment it is recommended to carry out its trial operation
for 2…3 days to reveal and eliminate possible errors of mounting and adjustment.
2.5. Software installation and detector adjustment with PC
2.5.1. The computer allows checking the signal level, change sensitivity parameters,
detection zone length, giving a signal, setting some parameters inaccessible for Preliminary
adjustment.
2.5.2. Software installation
2.5.2.1. You can download the latest version of setup software from our website
download menu http://www.forteza.com or find it on USB FLASH DRIVE which is
included in detector set.
2.5.2.2. Connect the sensor to PC with RS 485 with USB, power to the sensor. The
computer determines the type of USB device and installs the driver on COM-port. If the
driver is not installed automatically, the computer asks to install the driver. Follow IIIIIII
You can find driver in Forteza FMC SOFT file.
