Confidential AMTEK Version 7.3F 2015-11 Page 5 ©Inomatic 2015          1.  INTRODUCTION    1.1.  System Description  The  AMTEK  range  of  Acoustomagnetic  EAS  Systems  is  fully  compatible  with  all 58 kHz tags and Acustomagnetic labels on the market.  The  systems  are designed  to  get  optimum  detection  performance  and  to  avoid  false alarms at the same time by using digital signal processing and anti-noise algorithm.  The AMTEK systems can be operated in 2 configurations:  1.) Dual system 1 Transmitter and 1 Receiver antenna 2.) Split system 1 Transmitter and 2 Receiver antennas  Working  principle:  A  58  kHz  pulsed  magnetic  field  is  generated  between  the Transmitter (TX) antenna and one or two Receiver (RX) antennas. Any 58 kHz AM label or hard tag brought into the magnetic field will generate a signal which can be detected by the Receiver antennas and subsequently trigger an alarm signal.

Confidential AMTEK Version 7.3F 2015-11 Page 6 ©Inomatic 2015      1.2.  Typical System Performance  Depending on the AM tags used and the installation environment, the detection distance can  vary.  The  following  table  gives  an  overview  of  typical  detection  ranges  with  the different AMTEK systems and security elements.    Distances(m) AMTEK 250 AMTEK 350 AMTEK 750 F40 tag 2.5 2.6 2.5 Mini Pencil 2.2 2.3 2.2 Super tag II 1.8 1.9 1.8 DR label 1.2 1.9 1.8     1.3.   Additional Features    All Version AMTEK V7.3 systems are equipped with 2 additional alarms that allow an easier handling of certain situations.  The Jammer alarm indicated that the system is compromised by a jammer signal. The alarm light and buzzer sequence for Jammer alarm can be set via InfoNet  software. In this case the detection of the system is disabled to avoid false alarm.  The  Near  Tag  alarm is triggered  by  a  continuous  detection  of  a  stationary  security element in the detection zone. The alarm light and buzzer sequence for Jammer alarm can be set via InfoNet  software. By enabling the Near Tag alarm, one can easily detect tags that have accidentally been placed inside the system‟s detection area.  Both of the above described alarm features can easily be enabled/disabled by activating the respective checkbox inside the InfoNet software.  Programmable on/off time:  The system can be automatically switched on/off at certain times. The time for ON and OFF  can  be set via the InfoNet    software. The  system  will consume much less power during OFF time (Energy saving)
Confidential AMTEK Version 7.3F 2015-11 Page 7 ©Inomatic 2015      Incoming/outgoing alarm (only with integrated visitor counter):  The system is able to distinguish between incoming and outgoing alarm if equipped with the optional integrated visitor counter.  The alarm indication is different for the two types of alarms allowing easy identification of incoming and outgoing alarm.     Firmware update:  If a new firmware becomes available, the processor‟s firmware can be updated via the InfoNet software allowing update of new system features without replacing the electronics.     Selection of light/sound sequence:  The system alarm light and sound can be programmed in different sequences. Different aisle could have different sound sequence enabling the identification of where the alarm came from. It is also possible to have the alarm light on longer than the alarm sound to easily identify the alarm position. For multi aisle installation this feature is especially useful.     Remote Tuning/Service/Monitoring  In order to reduce the need for service calls, especially for remote places, our PRO- LINE systems can be accessed via Internet. The system service provider can log-in from their office into the system via infoNet Cloud (provided they are authorized) and diagnose/solve potential problems.     Integrated bidirectional visitor counter     Possibility to count customers per aisle and to determine the direction of movement (in or out of the shop)    Showing the importance of the alarm (is a customer moving in or out during the alarm)    Detecting undefined alarms    Pinpoint the exact aisle where the alarm occurred    Generate reports on visitor counts and alarm counts

SYSTEM INSTALLATION    This chapter covers the various issues related to Acoustic Magnetic systems and Electronic Article Surveillance systems in general, like:    Noise sources    Installation guidelines   3.1. Noise sources  Below there are various noise sources listed that might affect the performance of any EAS system. It is strongly recommended to either eliminate these noise sources (as far as possible) or maintain the largest possible distance to these noise sources. The following devices can create or absorb AM noise signals which can reduce the performance of an EAS system:    AM systems installed in other shops (even if they are installed up to 100m or more away from your store).    Any electronic device that operates around 58 kHz or produces harmonic frequencies around 58 kHz.    An active laptop. The back light in the screen can create a lot of noise which is detected by the EAS system and can reduce the performance dramatically. Make sure to keep laptop computers at least 3 meters away from the antennas.    (Moving) Objects containing metal, like sliding and revolving doors, elevators, escalators, roller shutters, frames, etc.    Electronic devices, like computers, laptop screens, LCD screens, cash registers, engines, transformers, etc.    Vertically positioned power cables, both low voltage and high voltage.    Lights (flashing, fluorescent, halogen, gas-de-charge, etc.)    Metal scan systems installed in close vicinity.    3.2.  System Part List  a.) 2x Pedestal AMTEK (1 TX and 1 RX) b.) 1x Power supply AMPSS 700V6 c.) 1x Connection cable TR AMCTR 710 d.) 1x Computer Cable LAN Cable AMCOM 710 e.) 1x Computer software infoNet V4 or higher
Confidential AMTEK Version 7.3F 2015-11 Page 19 ©Inomatic 2015      3.3.  Installation Requirements     Make sure all parts have arrived. Make sure there are no damaged parts. If there is any damaged part, notify the transport company.     Installation   shall   be  performed   by  a   qualified   installer   with   all  necessary national/local electrical/fire codes training.     If possible, connect a set of antennas (1 TX and 1 RX) and put them in the required position in the entrance/exit without drilling holes in the floor and bolting the antennas down. Switch on the system and test the performance. In this way the noise level and system sensitivity can be determined and if necessary (in case of high noise or poor sensitivity) the system can be moved to find a better position     The  pedestals  shall  be  placed  at  a  distance  equal  to  or  smaller  than  the maximum value depending on the kind of tag.     Avoid placing TX/RX pedestals near metallic structures (doors, frames, etc...) or neon/discharge lamps.     Metal framed doors may never swing between the EAS antennas, as this will distort the energy field of the system in such a way that it might result in high noise, poor detection and potential false alarms     Always install the TRX antenna on that side where the highest noise is or where the highest noise can be expected.     Not connected RX antennas nearby a running system  are to be avoided. They act as a big hard tag.     No power line (including power supply or TX antenna power line) shall be located in the same pipe/tube with the TX-RX interconnection cable.     Avoid unnecessary long cables. Run the power supply cables in a direct line to the EAS antennas. Never run power supply cables vertically up the wall within one meter distance of the antennas (never around the entrance/exit doorframe).     The AC source should be a clean AC source. If possible do not share the AC source with computers, neon lights/discharge lamps, or equipment with switching power supplies, make sure the “Earth” of the power supply plug is connected to the power supply socket.     Blown fuses shall be replaced with fuses of the same kind. ALWAYS UNPLUG power supply BEFORE CHANGING blown fuses!
Confidential AMTEK Version 7.3F 2015-11 Page 20 ©Inomatic 2015      3.4.  Installation Procedure       Remove base covers from pedestals.  Electronics will now be visible. Confirm all connections are firmly in place.     Place TX pedestal in the place to be installed.  Consider  the  position  of  AC  120V/60Hz  power source.  Ensure that  120V  60Hz AC source can be connected with the Power Supply and that the Power Supply output cable can be connected with the TX pedestal.  Avoid  placing  TX/RX  pedestals  very  near  metallic  structures  (doors,  frames, etc...) or neon/discharge lamps and LED, LCD monitors.     Place RX pedestal at the place to be installed.  It is  strongly  recommended  to  tune  the  system  to  its  final  working  conditions BEFORE drilling any hole! Depending on tag type, RX pedestal can be placed at different distances from TX pedestal (See “System Performance” on page 6).     Connect RX pedestal to TX pedestal using the connection cable AMCTR 710     Confirm all connections to the loops, receiver board, and processor board are firmly in place.     Before turning the system on, remove all 58 kHz tags near to it.     Connect Power Supply to the TX processor board with the 2-pin and 3-pin connectors     Connect  Power  Supply  to  AC  120V/60Hz  source,  switch  on  the  power supply.      Connect the computer via the LAN cable and start InfoNet software (for tuning please refer to the InfoNet manual)

TX Antenna Matching    All our  antennas are  pre-tuned  in the factory and  the  TX  Antenna matching WILL NOT  HAVE  TO  BE  ADJUSTED  manually  in  almost  any  case. When  installing  the system  near  metallic  frames  or  metallic  doors  (which  is not  recommended),  the resonance value may be affected and manual matching is required.     The LED bars TX1 and TX2 should light up completely when the system is powered on.                         If the LEDs do not light up at all, then check:     Whether “TX block” is activated by the respective checkbox inside the infoNet Software (see infoNet Manual for further details).   De-Activate the TX block if not done yet.     The LEDs should light up now.
Confidential AMTEK Version 7.3F 2015-11 Page 22 ©Inomatic 2015        If the LED bars do not light up completely on one or both sides, then:  It is necessary to  adjust the matching of the antenna loops. The AMTEK700V6 processor  board is  designed  to  be  used  for  all  AMTEK  systems.  Since  every AMTEK system shows slightly different antenna characteristics, the board allows the  selection  of  different  capacitors  for  each  antenna  loop  by  inserting  the respective jumpers. The matching capacitors are located at the upper part of the board.  The matching Level is shown by the LED bars TX1 and TX2:    TX1   TX2   Increasing quality of matching        If the antenna is mismatched, not all of the 5 LEDs of LED bars TX1 and TX2 will light up. In that case, the TX resonance of the upper and lower loop can be modified by changing  the  matching   capacitance   through  the  6   jumpers   in   the  relevant matching circuits (refer to default setting below).     Switch off the power first before you change any jumpers! Wait a while for the capacitors to discharge! High voltage!

RX Matching Circuit   All our antennas are pre-tuned in the factory and RX antenna matching WILL NOT HAVE  TO BE ADJUSTED in  almost  any  case.  When  installing  the  system  near metallic frames or metallic doors, resonance value may be affected.   The amplitude of the received RX signals is highly correlated to the matching of the RX board. Hence, when tuning the RX board‟s matching circuit, the signals displayed in the infoNet Software are important for the optimal tuning.     RX Matching:       TW2  TW1    CS1     X6   Set S3 and S4 to the default values according to your system:  Default setting of S3 and S4 for different AMTEK systems  AMTEK… TW2 TW1 250, 200 4 4 350 1 1 800, 750 0 0   Depending on the tolerance of the system components and environment, the default value might not be suited for optimum performance. If you have to tune the inductor CS1 please do it carefully with a non-metal screw driver, otherwise you might damage the ferrite core. For detailed description of the RX tuning refer to the infoNet Manual.

AM operating principle  The AMTEK AM systems operate on the pulse-listening principle. Using the zero crossing of the 50Hz mains frequency as a trigger, a short TX pulse of 58 kHz signal is transmitted and a receiver window is „opened‟ after the TX pulse has stopped. If a tag was present within detection range during the TX pulse, the resonance of this tag will be detected in the Signal (Receiver) window and an alarm will be triggered. A noise reference window is opened to detect the environmental noise. This signal is compared with the signal received in the Signal window and allows the software to properly distinguish a tag signal from a noise signal.  The figure below shows the AM operating principle (at 50Hz, with a default delay of 10μs) during one 50Hz cycle  DEL             TX Pulse  10ms  11.7ms  20ms         TX Pulse  1.6ms or 1.5ms (setting via InfoNet) LS1 Signal window 500μs LS2 Reference window 1000μs  DEL Detect delay 100μs

Synchronization principle  When multiple AM systems are installed in each other‟s vicinity, it‟s very important to properly synchronize the TX pulses and receiver windows for all systems involved. If systems are not properly synchronized they will create false alarms and poor detection. Keep in mind that AM signals, when compared to other EAS technologies, can “travel” quite far (up to 100m or more) because of their longer wavelength.    Two AM systems that are properly synchronized         SYSTEM 1                  SYSTEM 2            If two or more AMTEK systems are connected to the same main power phase they would not need to be synchronized by either hardware or software.

This might create false alarms and poor detection on system 1, whereas system 2 will function properly as the TX pulse of system 1 is not affecting the receiver window of system 2. This problem can be solved by making sure that both systems transmit and receive at the same moment, which can be realized by changing the “Syncron” value time for one of the two systems using InfoNet software.             SYSTEM 1                SYSTEM 2             Please note that any TX pulse should also not fall into to the Reference window LS 2 as it would push up the noise level of the system dramatically. The system may not alarm but the performance will be affected.

The necessary settings for hardware synchronization are described below. A description of the software-based synchronization is included in the infoNet Manual.  Hardware synchronization allows a number of X AMTEK systems to be synchronized with another AM system nearby by synchronizing only the AMTEK “Master antenna”. The “Slave antennas” will automatically follow the “Master” synchronization.  The LAN ports (LAN1 and LAN2) can be used for connection to the shop LAN and at the same time for hardware synchronization.  1.) One TX processor board has to be set as Master and the other(s) as Slave.  2.) The hardware synchronization ports (LAN 1 or LAN 2) must be connected with a shielded LAN cable.  The picture below illustrates the connection and the necessary settings for Master or Slave operation.

In order to proper terminate the Master/Slave Sync bus-cable, the Jumper J17 or 18 has to be inserted at the beginning of the sync bus-cable (usually Master antenna) and the end of the bus- cable (last Slave board).           To set to Master mode (the default mode), put the jumper J15 in position 2 and 3. For the antenna to operate in Slave mode put the jumper in position 1 and 2.      When using hardware synchronization,  you  must  set the synchron  value  to 0 for all “Slave TX” boards by means of the infoNet  software (see infoNet   Manual). Shifting  the  Synchron  value  for  the  master  TX  will  automatically  shift  the Synchron value of all connected slave antennas.   Please do not turn on the power before the configuration is ready. First switch on the power supply for the “Slave” antenna and then the power supply to the “Master” antenna.

Please note the sync cable (bus) has to be terminated to avoid interference. As such the first board of the sync bus, usually the Master board and the last Slave on the bus have to be terminated by inserting Jumper J17 or Jumper 18.
