A 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.

(DOJ) 01/01 The RF Transmitter/Receiver Board was redesigned because some components on the board were no longer available. This addendum contains the tuning procedure and service information for the new board. Note to Installers: For FCC compliance, system components must be located where persons are not likely to linger within 20cm (8") of the RF antennas. 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. 2SETUP AND SERVICE GUIDE DIGITAL MICROWAVE SYSTEM 915 8000-0395-02, REV.

The product consists of 2 field-generating elements, both of which are required to establish the zone of protection for the anti-theft function of the device. One field is a frequency hopping 900 MHz propagating wave, the other field is a 111.5 kHz electrostatic field. The 2 fields are combined in the anti-theft tag and the unique signal is detected by the receiver. As 2 fields are required for the device to function, we understand that the device is not considered a composite device. Also, as neither field is an independent function, i.e., both functions are needed for the tag to be detected, we understand that only 1 form 731 and one application fee is required. This is the same product for which a Grant was issued for a frequency hopping system in 1991 under FCC ID: BVC8V4EADX. The device is being resubmitted because the components for the synthesizer portion of the design are no longer available, necessitating the redesign of the synthesizer. The characteristics of the product remain the same. Should any additional information be required, feel free to contact me at [email protected], by phone or by fax per the numbers below.

FCC ID: BVCDMS915 Form 731 Confirmation No.: EA99160 Dear Sir or Madam: Sensormatic Electronics Corporation requests certain materials submitted with this application for certification of BVCDMS915 device be withheld from public disclosure. This request is made under the provision of 47 CFR 0.457 (d) and 5 USC 552(b)(4) Freedom of Information Act, Trade Secrets. The items for which confidentiality is requested include the block diagram and schematic diagrams. The information contains proprietary information (trade secrets) regarding the circuit operation and capabilities (specific values of components, circuit design details and system architecture) which are the result of our extensive investment in research and development. Without the disclosed information, competitive organizations would take considerable more time to assess and develop a workable competitive product. As a result, we believe that disclosure of these company-guarded materials would compromise our leading position in this market. We therefore formally request that the materials marked “Confidential” be kept strictly confidential and not made available for inspections by any other party, except on a need to know basis for the sole purpose of the certification process.

This is the same product for which a Grant was issued for a frequency hopping system in 1991 under FCC ID: BVC8V4EADX. The device is being resubmitted because the components for the synthesizer portion of the design are no longer available, necessitating the redesign of the synthesizer. Per 2.1043, changes to the basic frequency determining elements require an application for a grant of authorization. The changes to the design involve the replacement of the synthesizer circuit, as the original synthesizer chip is no longer available. All other aspects of the design (i.e., power output, hopping algorithm, frequency band, tag detection, etc.) remain unchanged. Sensormatic is not requesting approval of a new product; rather we are requesting approval of a replacement circuit in a mature product that was previously approved.

We are not introducing a new product into the market; rather, we are delaying the obsolescence of a mature product. We have replaced a circuit in a previously approved product because the original components became unavailable. You have asked the same question that was raised 10 years ago by Mr. Ed Gibbons. Please refer to item 3 of the exhibit, “Ed Gibbons Fax”. The issue was discussed with Mr. Dave Means in July of 1991. The transmitter produces a frequency hopping 900 MHz signal that mixes with a 111.5 kHz signal in a tag consisting of an antenna and a diode placed on merchandise to be protected. The system receiver receives the 900 MHz mixed signal and demodulates the modulation of the 111.5 kHz. Mr. Means assessment was that as a system, “the entire system meets the requirements of 15.247... As the receiver receives a spread spectrum signal and there is no issue of interference, the FCC will accept this system as a spread spectrum system governed by 15.247”. Please refer to exhibit “Dave Means Response”. Hopefully this sheds enough light on the issues to be able to issue a grant of authorization for this product.

Operation Overview 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 either 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.

General Information 1.1 Test Methodology Both conducted and radiated emissions testing were performed according to the procedures in ANSI C63.4-1992, and the requirements of 15.31, 15.33, 15.35, 15.207, 15.209 and 15.247. Radiated emissions measurements below 30 MHz were performed at a distance of 5 meters and the results extrapolated to the distance specified per 15.31 and 15.209. 1.2 Test Facility Measurements per 15.207 and 15.209 were performed at Sensormatic Electronics Corporation; measurements per 15.247 were performed at Timco Engineering , Inc. The Timco Report is attached as Section VII, Part C. The shielded room conducted emissions measurement facility is located at Sensormatic Electronics Corporation Headquarters at 951 Yamato Road, Boca Raton, Florida, 33431. The radiated emissions site is located at Sensormatic Electronics Corporation manufacturing location, 6600 Congress Avenue, Boca Raton, Florida 33487. These sites have been found acceptable by and are on file with the FCC per FCC letter 31040/SIT 1300F2. FCC ID: BVCDMS915 4 1.3 Test System Description. The DMS system consists of a power pack and separate antennas. The power pack consists an RF module, IF FM Detector module, E-Field Generator module, Processor module, Alarm module and external low voltage transformer. The modules are enclosed in metallic cans that are virtually hermetically sealed and include port decoupling. This design feature reduces the spurious emissions into the noise floor. The system produces an RF field and electrostatic field. The RF is propagated from a pair of antennas consisting of the following configurations: dual helixes, dish, or patch antennas. The electrostatic field is established between various radiating elements and ground. The installation configurations are fully described in the Set-Up and Service Guide exhibit. The product tested was a pre-production unit built to production drawings. 15.203. The product is professionally installed and tuned, thus it is compliant with the requirements of this clause. 15.204. The gain of each antenna including the required cable with reference to an isotropic radiator is as follows: Dual helix:+2.5 dB Dish:+1.8 dB Patch:-3.0 dB All antennas are manufactured by Sensormatic. III. Conducted Emissions Conducted emissions data are presented in Section VII “Data”, Part A “Conducted Emissions”. The product demonstrated compliance with the requirements of 15.207. The product was tested at 120 V, 60 Hz. FCC ID: BVCDMS915 5 IV. Electrostatic Field Radiated Emissions Of the several electrostatic field radiator configurations, the worst case configuration was determined to be the vortex bar. Radiated emissions data for this configuration are presented in Section VII “Data”, Part B1 “Electrostatic Field Radiated Emissions”. The product demonstrated compliance with the requirements of 15.209. Radiated emissions measurements were performed at 5 meters. Propagation loss was determined measuring the emissions at 5 and 10 meters and extrapolating the results to 300 meters as required. Maximum radiation was determined by first assessing symmetry while applying incremental rotation of the turntable. The product exhibited quadrant symmetry. Measurements were taken at radials of 22.5° throughout one quadrant; the measurement antenna was rotated for maximum pickup about the vertical axis of the measurement antenna at each radial. The maximum emission was determined to be with the measurement loop antenna in the vertical polarization, perpendicular to the plane of the vortex bar. The product was tested at input voltages to the transformer ranging from 102 – 138 V, 60 Hz with no measurable change in transmitter output. V. Frequency Hopping Requirements As stated earlier, the data for the 15.247 requirements are included in the Timco Report, included as Section VII, Part C of this report. Compliance issues not requiring measurements are presented below. The following information has been extracted from the original Grant (FCC ID:BVC8V4EADX) issued for this product in 1991. Pseudorandom Frequency Hopping Sequence. The random numbers used in the pseudorandom sequence was generated using the congruential method. Equal Hopping Frequency Use. Each of the 60 frequencies is used equally in that a “fixed list” of 60 channels is continuously repeated. The list of frequencies is fixed in that the sequence of the hopping channels is not shuffled or scrambled prior to each cycle. System Receiver Hopping Capability, System Receiver Input Bandwidth. The receiver tracks the transmitter using LO injection coupled from the transmitter. It also has the same filters…
