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

Typical Installations
DMS 915 components are arr anged in various
configurations depending on the applicatio n.
Typical installations are:
Slimline with plates
•
Concealed ceramic RF ante nnas with wire
•
cloth
Pedestal with plates
•
Pedestal with wire cloth
•
Pedestal with vortex
•
Micromax plastic RF ante nna with vortex

Slimline with Plates
The Slimli ne with plate system consists of tw o dish
type RF antennas, each mounted o n metal frames
which are enclosed in non-metall ic pedest als. A
transmitt er / r eceiver power pac k, RF antenna, and
an electrostatic f ield radiator plat e ar e contained in
one unit while the other pedestal has o nly an RF
antenna and another electr ost atic radiator plate.
The housings are faced toward each other at a
typical dista nce range from 3 to 6 feet depending
upon the installatio n. The ante nnas are connected
to the transmitter/ r eceiver via s hielded coa xial
cables.

Concealed Ceramic RF Antennas with
wire cloth
The Concealed ceramic RF ante nnas wit h wire
cloth system consists of tw o heli x type RF
antennas, eac h resting on the ceili ng tiles. The RF
antennas are faced t ow ar ds each other at a typical
distance range from 3 to 24 f eet depending upon
the installation. On the floor between the RF
antennas lays an electrostat ic r adiat or , a wire cloth
whose length is less than the separatio n betw een
the RF antennas. The wire cloth is usually
recessed in the floor or s ometimes placed on the
floor and covered wit h a rubber mat. The antennas
are connected to t he transmitter/ r eceiver power
pack via shielded coaxial cables. The
transmitter/receiver power pack has an optional
cosmetic enclosure.
