About the DMS 915

The Digital MicroWave System (DMS) 915 is a

microcontroller-based anti-theft system. The DMS

915 produces an alarm when it detects a

Sensormatic tag, a packaged semiconductor

diode.

To detect the tag, the system performs the

following operations:

• The system generates a “zone of protection,”

typically at a store exit. This zone consists of

two overlapping fields. The first field is a static

or frequency-hopping, frequency modulated

RF signal. The second field is a frequency shift

key (FSK) modulated and predominately

electrostatic field called an E-field.

• When a tag enters the zone, 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 modulation, and

compares the recovered modulation to the

modulation transmitted. If the two signals

match, the system issues an alarm.

The DMS 915 is programmed using an external

hand-held computer. Programmable features

include RF hopping bank or frequency selection,

RF power level selection, electrostatic field

frequency selection, “tag-too-close” function

enable/disable, alarm tone selection, alarm

duration selection, selectable hits required for

alarm, and alarm count set/reset control.

System Components

DMS 915 components include E-field radiators, RF

antennas, remote alarms, and a programmable

power pack

Three types of E-field radiators are:

• 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 the side of the exit.

• Vortex – a long aluminum bar hung across the

exit.

The RF antennas are used to radiate the

frequency-hopping, frequency-modulated RF

signal. These antennas mount in a variety of ways.

They can be concealed above the ceiling,

mounted in pods, concealed in the floor, or

mounted in pedestal enclosures located at the

store exit.

The remote alarm provides a audio/visual signal

that a tag has entered the “zone of protection.”

The power pack powers and controls the system.

The pack is typically concealed inside an

enclosure.

which are enclosed in non-metallic pedestals. A

transmitter/receiver power pack, RF antenna, and

an electrostatic field radiator plate are contained in

one unit while the other pedestal has only an RF

antenna and another electrostatic radiator plate.

The housings are faced toward each other at a

typical distance range from 3 to 6 feet depending

upon the installation. The antennas are connected

to the transmitter/receiver via shielded coaxial

cables.

Components:

• Power Pack

• RF antenna (dish)

• Electrostatic field Slimline plate antenna

Concealed Ceramic RF Antennas with

wire cloth

The Concealed ceramic RF antennas with wire

cloth system consists of two helix type RF

antennas, each resting on the ceiling tiles. The RF

antennas are faced towards each other at a typical

distance range from 3 to 24 feet depending upon

the installation. On the floor between the RF

antennas lays an electrostatic radiator, a wire cloth

whose length is less than the separation between

the RF antennas. The wire cloth is usually

recessed in the floor or sometimes placed on the

floor and covered with a rubber mat. The antennas

are connected to the transmitter/receiver power

pack via shielded coaxial cables. The

transmitter/receiver power pack has an optional

cosmetic enclosure.

Components:

• Power Pack

• RF antenna (helix)

• Electrostatic field wire cloth antenna

• Typical cosmetic mounting enclosure
