Technical Manual ARGUS AM Floor System 2 Introduction The ARGUS AM Floor System is a state-of-the-art anti-shoplifting system, which is completely integrated into the floor, making it invisible and which maximizes shopper experience. 2.1 Restrictions and limitations The following restrictions and limitations must be considered: 2.1.1 Software restrictions The ARGUS AM Floor Systems can be adjusted with Cross Point’s Device Explorer software.
Technical Manual ARGUS AM Floor System 3 General AM and EAS issues This chapter covers the various issues related to Acoustic Magnetic systems and Electronic Article Surveillance systems in general, like: 3.1 • Noise sources • Installation guidelines Noise sources Listed below are various noise sources that might affect the performance of any EAS system.
Technical Manual ARGUS AM Floor System 4 Installation requirements Listed below are EAS installation requirements to ensure a properly installed and functioning system. Not following these requirements might result in lower performance of the EAS system. 4.1 Installer/contractor 1. Shall have electrical work comply with the latest national electrical code, national fire code and all applicable local codes and ordinances. 2. Shall coordinate all work with other trades to avoid interference. 3.
Technical Manual ARGUS AM Floor System 2. LED display or other TV screens, switching power supplies or neon displays must be kept at least 2m away from the antenna coils. 3. Maximum cable length between the antennas and the Control Unit is 10m. Do not extend this cable, even with the same type of cable. If the cable is cut too short, do not attempt to rejoin the two ends since this will degrade the shielding performance of the cable.
Technical Manual ARGUS AM Floor System 4.3 Control Unit The ARGUS AM Floor System consists of a Control Unit to which two external coils must be connected. See chapter 10.4 for more details. 1. The Control Unit needs to be placed next to the entrance in such a way that store personnel can see the visual alarm and hear the audio alarm notifications. 2. Antenna cables must be connected properly to the designated antenna connectors on the Control Unit.
Technical Manual ARGUS AM Floor System 5 Equipment and tools The following equipment and tools are advised to use when installing and tuning the ARGUS AM Floor System. 5.1 General installation tools The general tools required for installation of an EAS system (drills, screwdrivers, cutters, etc.) are not described in detail. 5.2 Laptop computer To properly adjust the ARGUS AM Floor System through Cross Point’s software, it is strongly recommended to use a laptop computer.
Technical Manual ARGUS AM Floor System 6 AM operating principle The NEXUS AM operates on the pulse-listening principle. Using the zero crossing of the 50 Hz (or 60 Hz) mains frequency as a trigger, a short burst of 58kHz signal is transmitted and a receiver window is ‘opened’ after the transmission burst has stopped. If a tag was present within detection range during the transmission burst, the resonance of this tag will be detected in the receiver window and an alarm will be triggered.
Technical Manual ARGUS AM Floor System 6.1 Synchronization principle When multiple AM systems are installed in each other’s vicinity, it’s very important to properly synchronize the transmission burst and receiver windows for all systems involved. If systems are not properly synchronized they will create false alarms and have 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.

Technical Manual ARGUS AM Floor System 7 Installing the antennas To create a concealed system, the antenna must be integrated in the floor of the entrance/exit. To do this in an existing floor, a cavity needs to be created by removing concrete. In case of a new floor, the antenna and tiles need to be properly placed before concrete is poured. 7.

Technical Manual ARGUS AM Floor System 13.5.7 Entrances – selected device If you click on the ARGUS AM Floor System unit or panel in the 3D-view, some individual settings can be configured. In the bottom part of the screen, various buttons will be available. Scope view The Scope view screen shows the signals that are received by the ARGUS AM Floor System.
Technical Manual ARGUS AM Floor System Signals received by the ARGUS AM Floor System are processed based on the phase and anti-phase principle. This way it is better possible to distinguish between valid tag/labels signals and random noise signals. The settings related to this can be individually set for the phase and anti-phase mode, making it possible to obtain maximum sensitivity in anti-phase mode when, for example, more noise is present in phase mode or vice versa.
Technical Manual ARGUS AM Floor System Noise level indicator The noise level indicator, located on the right of each scope view image, shows a value between zero and one hundred, which represents the amount of noise that is being detected. A high noise level will result in reduced detection, which means that specified detection distances might not be achieved. To improve this situation, the noise source(s) must be located and removed when possible.
Technical Manual ARGUS AM Floor System Situation 2 SIGNAL detected but no continuous PHASE detected; result: no alarm Situation 3 SIGNAL detected and continuous PHASE detected; result: alarm Cross Point Device Explorer v1.
Technical Manual ARGUS AM Floor System Synchronization AM When multiple AM systems are installed in relative close vicinity of each other, it is of extreme high importance that the transmission bursts of all transceivers occur at the same moment. To be able to view and change the position of these transmission bursts, the Synchronization screen is available. When the Synchronization screen is open, the transmission burst of this system is disabled.
Technical Manual ARGUS AM Floor System Just hover the mouse cursor over our transmission burst (the cursor will change to a horizontal double arrow) and press down your left mouse button. While keeping the mouse button pressed, move the transmission burst and position it on top of the other system’s transmission burst. Together with moving the transmission burst, also the receiver window will move automatically since it has a fixed distance to the transmission burst.
Technical Manual ARGUS AM Floor System also receiver antennas are connected, the signals received by these receivers can be viewed by selecting the receiver from this list. Scan scale factor The Scan scale factor lets you zoom-in on the received signals. When this value is increased, the signals that are shown in the view will increase in size.
Technical Manual ARGUS AM Floor System Settings The Settings view screen shows various available settings for the ARGUS AM Floor System. Figure 48: Settings This page lets you select whether extra receiver antennas are used or not. In case you are installing an extended configuration, like transceiver antenna + 2 receiver antennas, then both checkboxes must be ticked to activate the receiver channels.
Technical Manual ARGUS AM Floor System Tuning AM The ARGUS AM Floor System is performing at its best when maximum power is being transmitted at 58kHz. The Tuning screen shows a graphical display of the transceiver antenna tuning.
Technical Manual ARGUS AM Floor System Figure 50: Maximized tuning screen The tuning of the transceiver antenna is influenced by the following factors: 1. The vertical distance between the transceiver antenna and metal in the floor underneath 2. The vertical distance between the transceiver antenna and the shielding tiles that are placed underneath 3. The horizontal distance between the two transceiver coils (default 30 cm) 4. Incorrectly connected transceiver coils.
Technical Manual ARGUS AM Floor System How to tune the transceiver antenna This section explains the proper way to tune the ARGUS AM Floor System transceiver antenna. 1.
