This completely new combination of outdoor detectors allows perimetral protection with coverage of up to 150 m. Microwave technology, combined with infrared sensors, eliminates the possibility of false alarms while maintaining high security standards. The microwave and active infrared signals are received and processed individually: the activation of the alarm signal comes as a result of precise synchronisms and a sophisticated coordination between the two technologies. Surveillance is carried out by means of a temporary window memory circuit. The pilot circuits of both detection technologies are equipped with a timer whose range is from 20 seconds to 2 minutes. The first device that receives a stimulus activates its own timer. During this time the other technology will be summoned to confirm the final alarm. Through this method of operation, false alarms caused by environmental factors are eliminated. The microwave device is the one that functions as the “activator” because, in most cases, it is activated first. Its detection capacity is determined by a lobe that can be regulated with its own trimmer. In a case where the infrared disqualification circuits start functioning, the sensibility of the microwave device decreases automatically, and during this time span (of disqualification) the barrier functions using one technology only. Moreover, as an option, an anti- crawling device can be installed, in case there are no crossing columns. In such cases, a Doppler short-beam microwave device is employed. This covers the blind zone in proximity to the barriers. In its basic configuration, ABSOLUTE is equipped with two pairs of active infrared devices, of which one is master and one slave. The transmitter sends a modulated infrared beam in the direction of the receiver. The receiver does not recognize continuous (unmodulated) infrared or visible signals: therefore it is completely immune to sunlight. The built-in disqualifying circuits de-activate the active infrared device in case of an attenuation of the signal, e.g. by fog, heavy rain or snowfall. INSTRUCTIONS FOR INSTALLATION Position the appliance in a sufficiently open area, strategically optimal for protection of the site. Local conditions must be thoroughly evaluated in advance so that the zone to be protected is delimited by the double technology sensor, physical obstacles like walls, fences and ditches or other systems of anti- intrusion surveillance. ORIENTATION The installation of the appliance requires that the transmitters and receivers placed in the two columns face each other, so that the two technologies may be aligned. INSTALLATION SITE The installation site must be chosen in such a way that the transmitters and the receivers are on the same level. Installation in sites with significant terrain irregularities must be avoided. If this is not done, blind zones for the microwaves as well as the infrared signals may occur, through which a trespasser could find his way in. The installator must also avoid positioning the appliance in zones with objects lying between the receiver and the transmitter (trees, bushes, etc.), as these could cause false alarms. Attention must be paid to the surface as well. If it is grass, it is important to trim it regularly in order to avoid its movement interfering with the microwave signal. If the installation is done on asphalt, the microwave must be raised by 20 cm, as described in chart TAB 1, page 13. This is necessary in order to avoid interference generated by reflections when the asphalt is wet. PLACING THE UNIT IN THE PROXIMITY OF BUILDINGS If the installation is to be done in the proximity of buildings, several rules must be followed: Metal Nets In order to avoid reflections that could create interference, position the columns in such a way that the appliance main axis is at a distance of at least 2 m from the maximum diameter formed by the microwave. This is because casual movements or vibrations of the metal nets caused…

Electric diagram and microwave-transmitter block diagram functioning description. Block nr.1 Block nr. 1 turns the alternating voltage applied to terminals 7 and 8 of the microwave into a rectified voltage needed to supply the voltage control of block nr. 2. Block nr.2 Block nr.2 regulates the rectified voltage at about 13,65V d.c.. This voltage allows to recharge an eventual floating battery and supplies the input voltage to the voltage control at 5V d.c. necessary to supply the logical processing circuit of the received signal. Block nr.3 Block nr.3 protects the circuit from eventual faults due to a polarity inversion of the eventually applied battery. Block nr.4 Block nr.4 consists of the parabola antenna and of the cavity which receive the signal in frequency emitted by the transmitter, and transformed into a sinusoidal input signal of the amplifier. Block nr.5 Block nr.5 consists of the two amplification transistors with corresponding polarization networks that allow to amplify the signal coming from the cavity. The signal will be even more amplified by operational U2B and corresponding polarization network. Block nr.6 and 7 Block nr.6, consisting of the dip-switch and the double exchange relay, selects the functioning mode of the microwave. During the test mode (alignment) the relay allows the breaking of the signal so as to inhibit the functioning of the automatic gain regulator during the alignment phases of the microwave. Block nr.8 Block nr.8 consists of the potentiometric trimmer R18, that allows to manually regulate the quantity of amplified signal to allow the alignement of the microwave with voltage values far from the saturation threshold of the amplifier. Block nr.9 Block nr.9 selects the frequency channel to compare with the received one. This selection takes place thanks to the dip-switch DV1. With all the dips in OFF position frequency nr.1=900Hz is achieved. With dip 1 in ON position freqency nr.2=1160Hz is achieved With dip 2 in ON position frequency nr.3=1500Hz is achieved With all dips in ON position frequency nr.4=2400Hz is achieved Block nr.10 Block nr.10 allows to filter the non-correlated frequencies with those received through the group of resistances and capacitors and the operational I1A. In output from this group there will be then a sinusoidal signal sufficient only when the frequency of the received sinusoid and the sinusoid selectioned on the receiver are in accordance. Block nr.11 Block nr.11 amplifies (U2A and corresponding polarization network) in a definite way only the received signal having a frequency corresponding to the one selected. Block nr.12 This block turns the amplified and received signal into a constant level rectified signal through the diode, capacitor and operational U3B rectification group. Block nr.13 Block nr.13 consists of the gain automatic regulation group(A.G.C.) that stabilizes the received signal at a constant level through U3A and transistor Q3. Block nr.14 This group (U5B) allows to have the rectified and stabilized signal in output at terminal M1 that allows the correct alignment of the microwave pair. Block nr.15 and 16 In this block the constant signal (comp) in output from the amplification group is integrated through the trimmer and the capacitor(R62, C27) that allow to control in installment phase the adjustment of the surveying modes of the object crossing the microwave in a more or less fast way. Block nr.17 This group (U4A and B) sets the alarm thresholds. In fact the outputs of these operationals are activated every time the rectified signal leaves the alarm window determined by the calibration of trimmer R45. The alarm thresholds are increased in case a pilot signal is sent to terminal 6. Block nr.18 Block nr.18 allows to stop the microwave functioning through an external signal applied to terminal M5. Block nr.19 Block nr.19 includes the control of the Darlington type transistor Q5 that allows to control the alarm relay. Block nr.20 The alarm relay supplies an exchange contact free of potentials for connections of the microwave to alarm control panels. Electric diagram and microwave-transmitter block diagram functioning description. Block nr.1 Block nr.1 turns the alternate voltage applied to terminals 7 and 8 of the microwave into a rectified voltage necessary to supply the voltage regulator of block 2. Block nr.2 Block nr.2 carries out an adjustment of the rectified voltage at about 13,65 d.c.. This voltage allows to recharge an eventual floating battery and supplies the input voltage for the adjusted supply voltage of the cavity driver and circuit logic pilot circuit . Block nr.3 Block nr.3 protects the circuit from eventual faults due to polarity inversion of the eventually applied battery. Block nr.4 Block nr.4 presets the oscillation frequency of the frequency generating circuit consisting of the operational group U1B. The presetting of the oscillation frequency takes place short-circuiting common terminal M9 with terminals M5, M6, M7, M8. Short-circuiting terminal M9 with M5 frequency nr.1= 900Hz +/- 5% is achieved. Short-circuiting terminal M9 with M6 frequency nr.2=1160Hz +/- 5% is achieved. Short-circuiting terminal M9 with M7 frequency nr.3=1500Hz +/- 5% is achieved. Short-circuiting terminal M9 with M8 frequency nr.4=2400Hz +/- 5% is achieved. Block nr.5 Oscillation block nr.5 forms the frequency square wave equal to the one preset in block nr.4. Block nr.6 Block nr.6 is the cavity control. The square wave form coming out of operational U1B controls the two control transistors that allow to have a higher power to control the cavity at disposition. Block nr.7 Block nr.7 consisting of the cavity and of the emitter parable allows to give rise to the sinusoidal frequency emitted by the antenna which is the frequency signal emitted by the transmitter.
