About the DMS 915
The Digital MicroW ave System (DMS) 915 is a
microcontroller-based a nti-theft syst em. The DMS
915 produces an alarm when it detect s a
Sensormatic tag, a packaged semico nductor
diode.
To detect the tag, t he system performs the
following operations:
The system generates a “zone of protection,”
•
typically at a st or e exit. This zone consists of
two overlapping fields. T he first field is a static
or fr equency-hoppi ng, fr equency modulated
RF signal. The second field is a frequency shift
key (FSK) modulated a nd predomi nately
electrost at ic f ield called an E-field.
When a tag enters the zo ne, it combines the
•
RF signal and the E-field into a composite
signal that radiates to the system RF
antennas. The system detects the composite
signal, separates the mod ulation, and
compares the recovered modulation to the
modulation transmitted. If the two signals
match, the system issues an alarm.
The DMS 915 is progr am med using an external
hand-held computer. Pr ogr ammable features
include RF hopping bank or fr equency selectio n,
RF power level selectio n, electr ost at ic f ield
frequency selectio n, “t ag- t oo- c lose” function
enable/disable, alar m tone select io n, alarm
duration selection, selectable hits required f or
alarm, and alarm count set/ r es et control.
mounted in pedestal enclosures loc at ed at the
store exit.
The remote alarm provides a audio/visual signal
that a tag has entered the “zone of prot ection.”
The power pack powers and controls the system.
The pack is typically concealed inside an
enclosure.
System Components
DMS 915 components include E-f ield radiator s, RF
antennas, remote alarms, and a programmable
power pack
Three types of E-f ield radiat or s ar e:
Wire cloth – usually recessed in the floor or
•
sometimes laid on the floor under a rubber
pad.
Plate – a metal plate concealed inside a
•
pedestal at t he side of the exit.
Vortex – a long aluminum bar hung across the
•
exit.
The RF antennas are used to radiat e t he
frequency- hopping, f r equency-mod ulated RF
signal. These ante nnas mount in a variety of ways.
They can be concealed above the ceiling,
mounted in pods, concealed in t he floor, or
