Features
Digital Signal Processing
The Sky-GuardTM system applies the l at est and most technical l y advanced DSP
technologies to address antitheft problems. It minimizes false alarms while
maintaining considerable detection range.
Smart Installation
Sky-GuardTM is the fir st smart installation loopi ng sys tem in the EAS industry,
which elim inates the need f or expensiv e technicians during inst allation. Due t o
a vari ety of entrance dimensi on, formal system has to be proper ly adjusted to
ensure the tr ansmitter adap tation. The Sky-Guar d
TM
is fr ee of this troubl e, as
soon as the pow er is app lied, the syst em will automatically detect the entrance
shape and tune the transmitter electronics to optimum performance, making
Sky-Guard
TM
a real plug and play looping system.
Self-Tuning El ectronics
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-Guard
TM
system, benefiting from its fully digital electronics, constantly
detects the env ironment & automaticall y adapts to any chang es. 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 typi cal app licati on of the s ystem is for the entr ance of 7 feet or bel ow, but
there may be special cases requiring the protection of even wider openings
which m akes Sky-Guar d
TM
advantag eous. Unl ike ot her syst ems with addit ional
bulk size pedestals, Sky-Guard
TM
only need to add few slim active antennas
according to the w i dth of ent ra nce, m aking system exp ansion e asy, simp le and
cost-effective.

Applications
Sky-GuardTM system simple i nstallati on consis ts of the syst em measur ing 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 ant ennas s hall be i nstalled. The system can be m ounted on eit her side
of doorway .
The Sky-Guard
TM
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
transmi tter. We als o recommend that t he when using a neon light, the s ystem i s
kept 12 f t away, if this is not possib le you can inst all our noise shi eld over the
transformer to eliminate this problem.

Quick Start Instructions
When all procedures of installation finished and the power applied on, the system
automatically enters the tra nsmitter 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 ensur e ev ery st ep of the i nstall ation is pr oper , all the co nnecti ons are cor rec t, a nd
the system still malf unctions or does not wor k w i th sati s f ac tor y sens i ti vity, pl eas e cal l our
technical support number (408-530-8070)
Accessories
