Page: 1 Overview Introduction Sky-GuardTM is an invisible system installed into a doorframe or mall entrance walls, without any obtrusive side panels or pedestals. The system eliminates the confliction between security merchandise tagging and integrity of store décor. Sky-GuardTM is fully automatic with self-tuning electronics, plug and play. It is the FIRST smart installation system of looping systems. It can be installed into any size of entrance frame without the adjustment of system. And it can also constantly change its phase to accommodate the environment that it protects. The Sky-GuardTM system is software driven EAS system that works in combination with any 58KHz tags and labels. The system’s transmitter sends out 58Khz signals, exciting tags within the detection zone, and the system receiver listens for the unique signal that any 58KHz tags and labels produce, and the sequence produced is then verified and multiplied in a fraction of a second.

Page: 2 Features Digital Signal Processing The Sky-GuardTM system applies the latest and most technically advanced DSP technologies to address antitheft problems. It minimizes false alarms while maintaining considerable detection range. Smart Installation Sky-GuardTM is the first smart installation looping system in the EAS industry, which eliminates the need for expensive technicians during installation. Due to a variety of entrance dimension, formal system has to be properly adjusted to ensure the transmitter adaptation. The Sky-GuardTM is free of this trouble, as soon as the power is applied, the system will automatically detect the entrance shape and tune the transmitter electronics to optimum performance, making Sky-GuardTM a real plug and play looping system. Self-Tuning Electronics Other manufacturers need professional technicians to tune the system to ensure proper functioning. But once the environment condition changes, the systems best working position changes and requires tuning again. The Sky-GuardTM system, benefiting from its fully digital electronics, constantly detects the environment & automatically adapts to any changes. It will always operate at its optimum performance from the beginning. Software Driven The Sky-GuardTM is fully digital software driven system, which allows unprecedented flexibility especially in later versions. System Expansion The typical application of the system is for the entrance of 7 feet or below, but there may be special cases requiring the protection of even wider openings which makes Sky-GuardTM advantageous. Unlike other systems with additional bulk size pedestals, Sky-GuardTM only need to add few slim active antennas according to the width of entrance, making system expansion easy, simple and cost-effective.
Page: 3 Applications Sky-GuardTM system simple installation consists of the system measuring 2.7”(H)21”(L) 5.4”(W), three passive antennas 3.1” long with a width of 1.5”, and built-in enunciator. Detection with a simple installation extends up to 7ft in all directions within the loop with 58k hard tag. If used with labels, some more detecting antennas shall be installed. The system can be mounted on either side of doorway. The Sky-GuardTM can be installed close to a metal door or frame with out decreasing the detection range, but once the material or environment around door entry changes, the system need to be reset to adjust the inductance of transmitter. We also recommend that the when using a neon light, the system is kept 12 ft away, if this is not possible you can install our noise shield over the transformer to eliminate this problem.
Page: 4 Parts List (For simple installation) Tx loop (9 m) Antenna holders (4 sets) System (1) with build-in alarm indicator Passive antenna (3 sets) System open picture
Page: 5 Installation Procedures 1. First loop the TX loop according to the outline of the gate frame. 2. Open the system housing, and mount the system on the one side of the gate as the diagram shows.
Page: 6 3. First mount the antenna holders 3 to 4’ above the ground (two holders for every side) , and scew the passive antennas into the doorframe. 4. Plug the antenna connections onto the system and do the same to Tx loop connection. 5. The power line connections are ready with the system when out of box, but if expansion of the power line is needed, the termination can be connected as the above diagram shows. The left terminal is for power line grounding, and the right terminal is for power line N and L terminations. N and L can be swapped. 6. Finally when all the connections ready, mount the housing onto the system and fix it by screwing down the screws at the upper and lower side of the system housing.
Page: 7 Quick Start Instructions When all procedures of installation finished and the power applied on, the system automatically enters the transmitter self-configuration condition. In this stage, you can hear the buzzer beeps regularly with a sequence of medium intervals. When the self-configuration accomplished, three beeps of short term intervals indicate that the system is ready for tag detections. Problems If you ensure every step of the installation is proper, all the connections are correct, and the system still malfunctions or does not work with satisfactory sensitivity, please call our technical support number (408-530-8070) Accessories A noise shield is available to cover the electronic transformer. This eliminates the problem of noise from the proximity of Neon Lighting.
Page: 8 Appendix (IR control keyboard function description) Default Parameters Table WGSPI Strongly recommends using the Self Tuning Mode when installing the system for the first time, please see [H] entry for instructions on how to operate this feature.

Than adjust Upuntil system is stable*Always Watch the system for about an Hour to ensure that you have chosen stable paramaters
Page: 10 Tuning Instructions 1. Firstly, open systems one by one if there are multiple systems works together. Make sure every system does not interrupt another if another is under self detection mode. (see entry H) 2. If the system is less sensitive, Firstly, adjust Minimum Signal Adjustment figures by a decrement of 20. The default number is 40. Please decrease the parameters by a step of 20 until the system reaches satisfactory sensitivity. Next but not important is to raise Gain Adjustment from 0(low) to 1(high), because usually the default settings is 1 already. 3. If the system gives false alarms, Firstly, shut down all the other systems (including all the possible noise source such as lights electronic equipment and etc.) If it doesn’t stop this system from false alarming, please follow the above two methods in an inverse way. A. Increase Minimum Signal Adjustment by an increment of 20. The range is from 20 to 200. B. Lower Gain Adjustment from 1(high) to 0(low). Secondly, if all the other systems works properly except that turning on this system renders others false alarm or shut down, please switch the L and N terminals on the power cord(see Power Cord Notice in above sections). 4. If any efforts followed by the above methods failed to eliminate the system false alarming or false alarms are stopped but system detection range drops below 6 feet, please call the number in the first page to ask for our help.
Page: 11 Parameters Configuration 1. press “start” button to initiate the control when panel shows the following state, initiation is ready. Fig. 1 2. Press password “961” Fig. 2 3. Press “confirm” button Then enter the control parameters input state. There usually are three steps in parameters input. Firstly, select the parameter type, like Gain Adjustment, Sychron Adjustment or Noise Condition Display; Secondly, input the numbers within a valid range; Thirdly, press “confirm” button.
Page: 12 Parameter Type Description A. Gain Adjustment (range: 0-1) There are two choices here, input 1 to select high gain, 0 to low gain. Fig. 3 B. Sychron Adjustment (range: 1-250; increment: 1) It is the time from zero crossing point to the start point of transmitting burst. This is usually set for multiple systems working on a different power line with phase problem. The range is 1~250, each stands for 34u seconds. Fig. 4.1 Under this entry, you can also see the different noise condition (from the light segment display and number indication) at a different phase when the adjustment goes on. It will help you to select a relative “clean” phase environment to set the system on. Fig. 4.2
Page: 13 C. Noise Condition Display (range: 0-3) The LEDs show signal or noise level by figures while the light segments bar shows the level by the number of segments lit. Select different parameter to choose the corresponding antenna channel to view tag and noise condition. (Note: If noise condition display is activated, alarm will be deactivated unless you input 0 to shut down the display) Noise Condition Display Configuration Table
Page: 14 Fig. 6 H. Minimum Signal Adjustment 1. Minimum Signal Adjustment (suggested increment : 20; valid range: 2-200) Change this figure to admit minimum signal amplitude, in another word any signal smaller than the level here will be ignored. Decreasing the number will increase the sensitivity of system but also at the risk of false alarming. Vise versa, increasing it will lower down the sensitivity to overcome the unexpected false alarming caused by uncontrollable environment noise. 2. Configuration Loading Mode Setting (range: 0-1) Also under this setting entry, there are three modes of system configuration loading. Inputting 1 will set the system to power on self-detection mode in which system will automatically configure all the parameters. By inputting 0, system will load the default parameters from Flash ROM. (See the default parameters table) If this parameter is bigger than 2(use as Minimum Signal Adjustment), system will load the latest saved parameters. Note: Default parameters are NOT equivalent to the latest saved parameters. Fig. 8
Page: 15 Exit button This button will return control box to last state. Save button This button will save all parameters to flash ROM, so when power shut down the parameters will not be lost. After press this button, you should press “confirm” button to confirm saving. Notice: But any adjustment of H as 0 (default parameters loading mode) or 1 (self-detection mode) will deactivate the application of the saved parameters. Fig. 9
