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.

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.

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.

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.

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.

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.
