A 20cm (8") setback is not required provided the antenna location does not promote lingering within 20cm (8") of the antennas. For example, do not locate antennas adjacent to a chair or bench. 8000-0395-02, Rev. B (10 pages) About this Guide This Setup and Service guide explains board replacement, an antenna connection change, tuning, and typical installations for the DMS 915 detector with the redesigned RF Transmitter/ Receiver Board. It is intended to be used as a supplement to the DMS 915 Installation and Field Service Manual, 8000-0395-01. Refer to the DMS 915 manual for a complete description of theory, installation, and trouble-shooting.

(DOJ) 01/01 MICROWAVE PRODUCTS 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. 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. Board Replacement The new RF Transmitter/Receiver Board (03002469-01) is not compatible with the old Processor Board (0300-0928-01). If the old RF Transmitter/Receiver Board (0300-0385-01) is replaced with a new RF Transmitter/Receiver board, the old Processor Board also must be replaced with Processor Board 0300-0928-02. Antenna Connection Change Connect the Impedance Matching Filter (SEC p/n 0400-1379-01) to the outer RF port (farthest from the IF module). Refer to Figure 1. Connect one of the RF antennas to the filter. Connect the other RF antenna directly to the remaining RF port. 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 SETUP AND SERVICE GUIDE DIGITAL MICROWAVE SYSTEM 915 8000-0395-02, REV. B Tuning Procedure The DMS 915 has been pre-tuned at the factory. If the detector is performing satisfactorily, no tuning is required. Figure 1. DMS Power Pack Connect matching filter and one RF antenna here Connect other RF antenna here To tune the detector, do the following: 1. Using the laptop configurator or Psion programmer, program the Power Pack to the following settings: E Generator Frequency - 111.5kHz System Type - 915 RF Power - 10 Select RF Bank - 903-905 Alarm Settings - n/a Number of Hits -1 Tag Too Close - On RF Frequency - 904.2 RF Modulation - Off IFI Tx/Rx Tx/Rx RF Transmitter/ Receiver 2. Connect the oscilloscope probe to the “Recovered Modulation Monitor” test point located in the IF Module (Figure 1). Set the vertical sensitivity to 1Volt/division and the time base to 0.5 millisecond/division. Recovered Modulation Monitor IF FM Detector 3. Move a tag around in the field and change its orientation until a signal of two volts peak to peak is observed on the scope. If necessary, the amplitude of the E-Field Generator can be adjusted to achieve this value. 4. Adjust the variable capacitor on the antenna side of the Impedance Matching Filter until the signal on the scope is at a maximum. Adjust the variable capacitor on the power pack side of the filter to further maximize the signal amplitude. Repeat this adjustment sequence of the capacitors until the signal reaches its maximum peak value. Note: If the amplitude of the signal exceeds four volts peak to peak at any time during this adjustment, turn the E-Field amplitude down to two volts peak to peak to prevent saturation of the amplifiers and consequently false readings. IFO Processor Programmer Input E-Generator 5. Using the configurator, reset the System Type to “915HOP” after tuning has been completed. DIGITAL MICROWAVE SYSTEM 915 8000-0395-02, Rev.
