5. SENSOR STRUCTURE & OPERATION
5.1. Sensor Principle of Operation
5.1.1. The sensor is a bistatic microwave device.
The principle of the sensor operation is to generate an electromagnetic field in the space between a transmitter and a receiver. This field provides a volumetric detection zone in the form of a long ellipsoid of rotation.
5.1.2. An intruder crossing a detection zone causes changes of the field. All changes of this field are recorded. The signal passes through the amplifier and is compared with the value thresholds according to the algorithm. If the signal’s change on Rx input is provoked by a person passage, Rx generates an alarm breaking output contact of the relay.
The signal on Rx input can be changed under the influence of other factors: height and weight of the intruder, place of the sector’s intersection, its relief, speed of the movement.
5.1.3. The signal on Rx input can be changed under the influence of other factors: rain, grass, small animals, electromagnetic interference, swinging of branches, gates entering the detection zone commensurable with an intruder movement. Other reasons, e.g. location of extensive constructions, objects in the detection zone or near from it like as fences, walls, irregularities, snow, grass can influence on the level of Rx input signal. In theses cases because of big reflections and interference the detection zone configuration jumps. Multi thresholds algorithm of the sensor operation permits to decrease the number of alarms provoked by interference. That’s why it is necessary to observe the recommendations in the subsection 8.1!
5.2. Adjustment, Control and Indication Parts
5.2.1. An alarm generates the values of the Rx thresholds. An explorer establishes them during the operation with the controller of the thresholds “MIN-MAX”. The thresholding is realized by the main rotation of resistor axis with screwdriver. In this case the thresholds will change from minimum (MIN) to maximum (MAX) value.
5.2.2. The input signal is controlled with the tester on the socket that is marked
"TEST" (test jack).The more TEST the more Rx input signal and vise versa. The sensor keeps its operation with the range of the voltage values too: TEST 0,1 - 4,8 V.
5.2.3. The light indicator “PROTECTION” provides the indication of the sensor mode operation:
5
- Continuous luminescence means the standby state of the sensor;
- The indicator’s switching off for 3 sec means the alarm generation.
Pressing the button "AGC" on Rx it is possible a broken glow of the indicator
“Protection”. To decrease the power consumption, the indicator “Protection” goes out after
10 min of the sensor operation in the standby state if there were no pressures on the button
“AGC”, the turn of the levels controller, transfer of the sensor in the alarm mode. In this case the indicator disconnection doesn’t influence on the state of the relay contacts.
5.2.4. During Rx and Tx adjustment on the maximums of the antennas directional diagrams, the amplifier is transferring from the mode of the adjustment with a big time constant to the mode with a small time constant by pressing the button “AGC” (automatic gain control) on Rx. In this case an express setup of the amplifier takes place on the standby state.
5.2.5. A “normally closed” tamper loop is provided to prevent unauthorized opening of the back panel of the Rx unit. In the operating condition the tamper circuit’s contacts are closed, during the back panel opening they are broken. The alarm cables circuits marked “TAMPER”; “TAMPER” are broken too.
5.3. Sensor Operation
5.3.1. The sensor operation provides the following suite:
- Preparation of the sector
- Signal cables and power supply laying
- Tx and Rx installation
- Sensor connection (connection of power supply and loops of intruder alarms)
- Alignment of Tx and Rx antennas
- Setup of Rx thresholds.
The principles and the methods of the operations’ performance are given in items 8-
10.
5.3.2. The sensor has the following operating regimes:
- Standby state (contact breaking)
- Alarm signal (open condition)
- Tamper state of Rx (the contacts of the tamper circuit are opened).
5.3.3. The receiver control device realizes the receipt and the indication of alarms.
The sensor operates with the receiving- control devices providing the check of the relay contacts.
5.3.4. During the operation the remote control checks the sensor efficiency.
The constant voltage 5…30 V for 1…3 sec is realized on the Tx wire marked “RC”. The beaming of Tx is interrupted for the time of the signal “RC” operation. Then Rx generates an alarm. In such a way the signal generation after the signal “RC” confirms the
sensor operation and the running order of the loop.
The user determines the control periodicity.
5.3.5. Besides there it is necessary to check periodically the technical state of the sensor and its servicing. Periodicity of the checks is given in item 11.

6. SENSOR CONSTRUCTION
The sensor consists of separate units (Rx, Tx) placed in dust-, splash-proof enclosures.
6.1. Rx Construction
6.1.1. Rx Construction and its fastening elements to the support are given in fig. 6.1.
The carrier of Rx 1unit is a parabolic antenna. The exciter is fixed inside of this antenna
(in the focus of parabola). The detection camera is installed on this exciter with the flange.
The processing module is fixed on the sidewall inside the antenna. Rx connection to the JB or SU is realized with the cable 14 coming through the cable entry. Rx is fixed on the support with the bracket 9 and buckles 8. First the bracket is fixed on the support, and then
Rx is fixed to the bracket with the nut 11. The access to the controls, adjustment, indication elements and clamps for the connection of the terminal element is open when the cover 10 is removed. The adjustment and indication elements located under the cover
10 are given in fig. 6.2.
The main operating position of Rx is given in fig.6.1. In the cases when it is impossible to fix Rx at the left from the support, it can be fixed on the right from the support. In this case the screws 2 should be installed in two holes in the upper part of
the antenna, and two holes of the antennas should be opened in the lower part. They are necessary to prevent the condensate inside the antennas.
6.2. Tx Construction
6.2.1. Tx construction and its bracket are the same as the Rx construction (see fig.6.1). The difference is in internal elements: the microwave generator is fixed on the exciter instead of the detection camera which is connected to the modulator; cover 10, controls, adjustment and indication elements are absent.

Note. Dear user! The manufacturer of the sensor constantly upgrades their quality and reliability. That’s why in some lots of sensors one can find design modifications unspecified in the documents delivered with the sensors. Nevertheless, the main
specifications are valid.
7. SAFETY MEASURES
7.1. The current safety standards for the operation with electrical facilities with up to
1000 V voltage should be observed during mounting, prevention and repair of the sensor.
7.2 Cables should be laid, terminated and connected to the sockets only when supply voltage is OFF.
7.3. It is prohibited to mount and to maintain the sensor during lightning storm.

8. MOUNTING PROCEDURE
8.1. Requirements for the preparation of the sector and the arrangement of Rx and Tx
8.1.1. 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 sensor can worsen. In this case the issue of the sensor’s use under these conditions is defined by the trial operation. b) The height of the grass should not exceed 0,4m; c) The height of the snow should not exceed 0,9m; at the sector’s length less than
50m the height is 1m max; d) 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; e) On the sector there should not be situated moving leaves, bushes, trees, etc. at the distance of ±1,0 m from the axis connecting Tx and Rx at the sector’s length less than
50m; at the distance of ±2,2 m at the sector’s length up to 250m; at the distance of ±3 m at the sector’s length up to 500m; f) The width of the sector should be not less than the width of the detection zone
(see table 3.1);
The sensor can be mounted if the width of the sector is less. The alarm of the Rx output can be very small or absent. In this case the Rx antenna or Tx is installed from other side of the support. Besides there in some cases the sensors interference can be reduced. It is determined by the trial operation;
g) The sector’s length is:
“Forteza-300” - 10…300m;
“Forteza-500” - 10…500m; h) The sector’s incline isn’t regulated.
8.2. Sensor Mounting
8.2.1. Mark the perimeter for the places where the supports are mounted. To organize the continuous boundary of the protection, the joint Tx and Rx installation of adjacent perimeter grounds isn’t permitted. The right units’ installation of adjacent perimeter grounds is Tx and Tx, Rx and Rx.
8.2.2. Mount the supports. It is recommended to use metal or asbestos-cement tube as supports of 150…200mm diameter. As the sensor hasn’t “dead” zones two Tx (Rx) units can be installed on every support of adjacent perimeter grounds.
8.2.3. The supports are mounted with concreting.
The user can apply other variants of the sensor mounting (for example guarding, building wall) according to the results of the trial operation. As the guarding deforms the detection zone configuration, the sensor operation depends on the exact place of its mounting.
8.2.4. Lay the main cables according to the project of the security systems.
8.2.5. Install the brackets 9 on the supports 5 of Tx and Rx units (fig.6.1). For that join the upper buckle 8 with the bracket 9 using the nut 6. Screw a nut tight for 2…3 turns.
10
Wrap the buckle round the support and fix it from other side of the bracket by the screw 3 using the nearest hole on the buckle. If the bracket is fixed not well on the support pass the screw 3 through the hole shortened the buckle.
Install similarly the lower buckle 8. Then provide the good bracket’s fixing on the support with the nut 6. Unbend or cut off the surpluses of the buckles.
8.2.6.
Install Tx and Rx units on the brackets with the nuts 11. Pass the cable 14 through the corrugated tube 15. The installation of the corrugated tube is obligatory.
ATTENTION! To reduce the level of electromagnetic interference induced on supply lines it is recommended to mount SU at the distance of 300 m maximum from
the place where the sensors are installed.
8.3. Sensor Connection
8.3.1. Switch ON the necessary supply units, signal circuits, remote control circuits.
Rx and Tx units are connected with its own alarm cables. The wires are marked. The marking of cable conductors is given in table 8.1.

8.3.2. The type and the nominal of the terminator of the security systems loop
(resistor, condenser, and diode) are determined by the type of the control device. The sensor is connected to the control device. Usually it is a resistor. The nominal resistance of this resistor should take into the resistance of the relay contacts (≈30 Ohm) of the lightning circuit (this resistor - 100 Ohm) and resistence of the security systems loop (depends on the chosen cable type and its length). Rx has the clamps to install the terminator marked
“T” (see fig.6.2). The manufacturer provides the clamps shortening with the jumper. If the terminator is installed not on the clamp but in other place, the jumper isn’t removed and provides the integrity of the security systems loop.
8.3.3. The contacts of the tamper circuit (“TAMPER”) of Rx can be connected to the receiving-control device by the separate loop. In this case the user receives the information of the opening of the Rx terminal cover 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 terminal cover on one channel of the control device.
8.3.4. There is the scheme (see fig.8.1) of the sensor connections using the junction box “Barrier-JB”. The contacts of the tamper circuit will be switched on in series with the relay contacts. The sensor receives a signal from remote control (RC) when an additional
11
button is installed in the room. It is possible to install one button on some sensors. In this case the button pressing checks the sensors operation of all group sensors.
There is the model scheme of the sensor connection using the storm protection unit
“LGU-4” (see fig.8.2). During the mounting of the storm protection unit “LGU-4” it is necessary to install them near Rx (Tx) units. The best installation is instead of the JB (if the quantity of the switched circuits is 8 items max).
There is the model scheme of two sensors connection to the supply unit “PSU 24-0,
7” (see fig.8.3).

9. PREPARATION OF THE SENSOR FOR THE OPERATION AND
ADJUSTMENT
9.1. Sensor Preparation for its Operation
Check the right connection of supply circuits and output circuits of the sensor.
Take away the cover of Rx and connect the terminator to the clamps “T” after removing previously the jumper.
9.2. Adjustment of Tx and Rx
9.2.1. Tx and Rx antennas are adjusted at the height of 0,5m.The height’s count is realized from the lower antenna to the ground (fig.6.1).
To provide the sensor availability, it is necessary to adjust Tx and Rx antennas.
9.2.2. The alignment includes the following procedure:
- Loosen the nuts 6 and 11 (see fig.6.1);
- Revolve Tx (Rx) antennas with the brackets round the support, incline the antennas vertically, then adjust them. Use the aiming cleat situated on the sidewall of the antennas;
- Tighten the nuts 6;
9.2.3. Adjust exactly Tx and Rx antennas from the sector’s angle.
- Switch on the sensor;
- Open the cover 10 of Rx (fig.6.1);
- Connect the voltmeter with the alarm cable from the sensors kit to the socket
“TEST” of Rx to check the signal’s level received by Rx;
- Press the button “АGC”. Pressing it and stooping in turn Tx and Rx vertically exact
the maximum indicated value of voltmeter.
- Ease the button “АGC”.
- Check the value of “TEST” voltage as a result of the adjustment. If “TEST” voltage is less than 1,2 V, it is necessary to repeat the alignment vertically and horizontally for more exact adjustment. If the voltage controlled by the voltmeter is over 4,5V (on short sectors), it is recommended to make the desalignment of Rx and Tx upwards at a small angle so the voltage does not exceed 4,5V. Don’t desalign Rx
and Tx down or towards. The sensor keeps its operation using “TEST” voltage
0,1…4,8V. The boundary values of 1,2V and 4, 5V during the adjustment are recommended for the resource of the signal level to provide a long operation;
14
Tighten the nuts 11;
Disconnect the tester from the socket “TEST”.
9.3. Rx threshold
9.3.1. Mount the controller “MIN-MAX” in the position MAX.
Thresholds are adjusted when a person crosses a protected sector uniformly along the whole length. It is necessary to go out from the DZ of 1-2 m for Rx calming (otherwise the results of the previous passage will influence on the following). When the sensor generates alarms, “PROTECTION” indicator becomes to dim for 3 sec. The following passage can be done after the switching ON of the indicator “PROTECTION”. If the signal is not generated during the investigator passage, the controller “MIN-MAX” will be turned on one-two points counter-clockwise and the alignment will be continued.
Do some check passes along the whole length of the sector especially in the “problem” sector places: in hollows, hills, next to the trees branches situated in the detection zone. If it is necessary regulate the detector thresholds.
Align the thresholds very attentively as “decreasing” the thresholds a lot of false alarms can be taken place because of some interference; “increasing” the thresholds some sensors omissions appear in its operation.
When the adjustment is over, it is necessary to close the Rx terminal cover.
9.4. Check of Sensor Operation
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.
10. OPERATION OF THE SENSOR WITH THE DEFLECTOR
10.1. If it is necessary to create breaking of the detection zone the sensor “Forteza-
300/500” (“Forteza-300/500T”) can be used with the deflector (fig.10.1).
10.2. A metal sheet (its dimensions no less than 1*1m) is used as a deflector. During mounting the deflector should be adjusted at the angle of the place and have reliable fastening to exclude its vibration when it is windy because it can cause false alarms.
10.3. During the operation through the deflector the total length of the detection zone does not exceed 150m for “Forteza-300” (“Forteza-300T”) and 200m for “Forteza-
500” (“Forteza-500T”). deflector
Tx Rx
Fig.10.1
10.4. Procedure of Operation
10.4.1. Mount Tx, Rx and the deflector according to item 8.2.
15
10.4.2. Align Tx and Rx in the direction of the deflector with the aiming cleat. Open the Rx terminal cover 10 and connect the tester to the socket “TEST” with the alarm cable.
Switch on supply voltage.
Changing the position of the deflector, Tx and Rx units, obtain the signal on the socket “TEST”. Carry out exact alignment according to item 9.2.
10.4.3. To define the optimal position of the deflector it is possible to use a laser pointer. Place a mirror on the deflector (the plane of the mirror should be parallel to the plane of the deflector) and fix the pointer (keep it) in the center of Tx unit. Direct the pointer beam on the mirror center. Changing the position of the deflector it is necessary to obtain the beam from the pointer to be in the center of Rx.
Switch on supply voltage and carry out the exact alignment of Rx, then the alignment of Tx according to the methods given in item 9.2. Adjust the operation thresholds of Rx according to methods given in item 9.3.
11. CHECK OF TECHNICAL STATE
11.1. Check of Sensor Operation
11.1.1. During the sensor exploitation it is recommended to check remote control
(“RC”) 1…3 times in a day.
11.2. Servicing
11.2.1. The sensor should be served by the technicians after special training and instruction.
11.2.2. During the service of the sensor it is necessary to conduct check and preventive works.
11.2.3. Every month carry out external examination of the sensor units and the state of the sector where Tx and Rx are installed.
It is necessary to check:
- the absence of dust, dirt, snow and ice from the side of radiation of Rx and Tx antennas and clean them if it is necessary;
- the absence of outside objects in the sector where Tx and Rx are installed.
11.2.4. Every quarter:
- carry out all the works specified as works carried out every month;
- check the state of the cables and cable connections.
11.2.5. During seasonal works it is controlled the height of the grass. If the height of the grass is over 0,3m the grass should be cut or removed by another method.
11.2.6. If the height of snow changes, false alarms can be generated because of the decrease of the signal at the input of the receiving unit. In this case it is necessary to remove snow or to change the height of Tx and Rx antennas installation.
After the height of the antenna mounting is changed, they should be aligned. The thresholds should be adjusted according to the procedure given before.
