May 20, 2005 FCC Application Processing Branch Attn: Linda Elliott, [email protected] , Correspondence Reference # 28690 Stan Lyles, [email protected], Correspondence Reference # 28877 FCC ID: HCQ3B6ETOEMM 731 Confirmation Number: EA559274 Re: Modular Approval Cover Letter, per FCC Public Notice DA 00-1407 Dear Ms. Elliott and Mr. Lyles: In response to the first item in the correspondence I received from both of you that asks us to submit external photographs, let me reiterate that the application we are submitting is for a “module” only. The module will be installed into a housing of some sort by the OEM that buys the module from Inovonics Wireless Corporation. Therefore, we can only provide you with pictures of the module itself. However, the module will bear the FCC ID number and will include instructions for label placement on the exterior of the final product (text of which is included in the body of this letter). Submitted along with this cover letter is a picture of the board showing the placement of the label containing the FCC ID number. In compliance with FCC Public Notice DA 00-1407, we are submitting this cover letter requesting modular approval, and this letter addresses the eight requirements identified in the Public Notice: FCC Modular Application 1.) The RF portion of the circuit has its own shield. The module is not dependent on any additional shielding. 2.) This transmitter only accepts a switch closure for data input. The rate at which the input switches affect modulation is controlled by a micro-controller; excessive data rates are not possible. 3.) The modular transmitter has its own voltage regulator, VR2 on the schematic. 4.) The antenna on the modular transmitter is a printed trace on the PCB; it is permanently attached. 5.) The module was tested in a stand-alone configuration. Power was supplied by a 3.2 volt battery. 6.) The modular transmitter will be labeled with its own FCC ID number (see submitted picture), and the modular transmitters will include the following instructions for exterior label requirements: FCC Modular Application Page 2 “FCC Label Requirements for EN1941 Inovonics Wireless has received Federal Communications Commission (FCC) approval to market RF modules. The application integrator is responsible for properly labeling the product containing the RF module. Labels must be placed on the outside of the product, and must include a statement indicating that product contains the module, along with the FCC number. Example 1 “Contains RF Module FCC ID: HCQ3B6ETOEMM” Example 2 “Contains FCC ID: HCQ3B6ETOEMM” RF Module FCC Registration Number EN1941 • FCC: HCQ3B6ETOEMM” 7.) The modular transmitter was tested to and conforms with Section15.247. 8.) RF Exposure Information: The device is compliant with both MPE requirements (47CFR2.1091) as well as SAR requirements (47CFR2.1093). Calculation for compliance with MPE requirements (47CFR2.1091) is done using a worst-case transmitter power of 50 mW, assumption of a unity gain antenna, and an exposure limit of 0.6 mW/cm 2 (f/1500 mW/cm 2 at 20 cm per 47CFR1.1310) for general applications. This device is not carried or worn by the user. It has an extremely low duty cycle and a low rate of transmission that dramatically reduces the average power level that could pose an exposure hazard. The OEM transmitter initiates a transmission upon sensing a change of state. In addition to these change-of-state transmissions, the transmitter is configured to transmit a supervisory message once every 3 minutes. The maximum message length may occur when the OEM transmitter transmits a serial message consisting of a 12 ms preamble followed by 32 ms of synchronization, identification, payload, and CRC data. The averaging interval specified in Table 1(B) of 47CFR1.1310 is 30 minutes. For the purposes of this calculation, it is assumed that ten supervisory and five change-of-state messages will be sent in the 30-minute interval. Each supervisory message consists of 3 redundant packets, and each change of state message contains 21 packets, for a total of 135 packets in the 30-minute interval. A packet is typically 22.4 ms in length. For this calculation, a maximum packet length of 44 ms will be used. The worst-case average power density at a distance of 20 cm is then, 223 8.32 )20(4 1 1060 min144 min30 135 50 cm nW cmms packet mspackets mW=× × ××× π FCC Modular Application Page 3 This is well below the 0.6 mW/cm 2 MPE limit. Calculation for compliance with SAR requirements (47CFR2.1093) is done using a worst-case transmitter power of 50 mW time-averaged by the duty cycle of the transmitter, and the assumption that all RF energy could be absorbed in 1 gram of tissue. The peak exposure limit is 1.6 mW/g (equivalent to 1.6 W/kg per 47CFR2.1093) in any 1 gram of tissue for General Population/Uncontrolled applications. In any 3-minute interval, worst-case the device may transmit up to 2 alarm messages and a supervision message for a total of 45 packets.

Responding to item number 3 in Correspondence Reference Number 28877 from Mr. Lyles, I extracted the Test Set-up Photos from the IA Labs Test Report and am submitting them as a separate file in this re-submission of the application. Also, we are submitting a revised Operational Description. The fourth line in the last paragraph has been corrected and I highlighted it in red. Any further communication should be directed to my attention, since I am the person responsible for the FCC application submissions.

Testing was performed in 3 different orthogonal axis to determine the worst case emissions from the device. The worst case emissions measurements are shown in this report. FCC CFR47 Part 15.31: Measurement Standards: In any case where the device is powered off a battery, a fresh battery was used during test. In cases where the device is powered off an AC supply, voltage was varied per Part 15.31 to find worst case emissions. FCC CFR47 Part 15.35: Measurement Detector Functions and Bandwidths: FCC Part 15.35 was utilized when performing the measurements within this report. In any case where the device is powered off a battery, a fresh battery was used during test. In cases where the device is powered off an AC supply, voltage was verified per Part 15.31 to find worst case emissions. The actual test distance for the FCC Part 15.209 testing was conducted at 10m for the fact that the device was being tested to EN55022 Class B from 30 MHz to 1000 MHz (meets/exceeds the FCC Part 15.209 & 109B limits) The data is automatically extrapolated back to the FCC 3m limits and measurements are corrected to better show the compliance to FCC requirements and reduce confusion. A correction factor of 10.54dB is used in cases of 30MHz and up for a difference between 10m and 3m measurement distances. All measurements that are lesser than 30MHz where applicable are accompanied with the fall of measurements and calculations to support the interpolation.

FCC ID: HCQ3B6ETOEMM EN1941 12. Test Report Additional Information The test report containing intentional/unintentional emissions data is attached as “11-TestReportIALabs-EN1941.pdf”. International Approvals Laboratories generated this report. Additional data demonstrating compliance with 47CFR15.247 follows. For the following measurements, the antenna was replaced by a coaxial connection to an HP8594E spectrum analyzer. Minimum Channel Separation: Plot 1 is a spectrum plot showing a minimum channel separation of 800 kHz. Compliance with section 15.247(a)(1) is demonstrated by capturing several transmissions over a small portion of the 902-928 MHz ISM band. Plot 1: Demonstration of channel spacing requirement. FCC ID: HCQ3B6ETOEMM EN1941 Number of hopping Channels: Plot 2 demonstrates compliance with 15.247(a)(1)(i) — Number of hopping channels. This is a stored display of many sequential transmissions to show the overall band occupied by the transmitter. The marker at 919.20 MHz represents the maximum conducted transmitter power across the band. Plot 2: Demonstration of 25 hopping channels. 20 dB bandwidth of a single channel: Plot 3 shows the 20 dB bandwidth of a single channel to demonstrate compliance with 15.247(a)(1)(i). The 20 dB occupied bandwidth is 253.8 kHz. Plot 3: Demonstration of occupied bandwidth. FCC ID: HCQ3B6ETOEMM EN1941 Average radiated measurements for harmonic and spurious emissions: With regards to average radiated measurements for harmonic and spurious emissions that fall in the restricted bands of section 15.205 of the FCC Rules. This device uses pulsed operation, section 15.35(c) states, “Unless otherwise specified, e.g.§ 15.255(b), when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds.” This device transmits for 20ms out of every 100ms and therefore has a duty cycle of 20%. Per section 15.35 the peak harmonic and spurious emissions may exceed the General Radiation Limit found in 15.209(a) by the ratio of the duty cycle, which in this case results in a 14 dB relaxation of the limit from 54 dB μV/m to 68 dB μV/m (above 1000 MHz) for the peak measurements shown in the report. Peak conducted RF power output measurements: Pursuant to FCC Public Notice DA 00-705, the following measurements were made using an Agilent 8594E spectrum analyzer having the following settings: Span: 1250 kHz (approximately 5 times the 20dB bandwidth) RBW: 300 kHz (RBW > the 20dB bandwidth) VBW: 300 kHz (VWB ≥ RBW) Sweep: auto Detector: peak Trace: max hold The device is modified so that the antenna is removed and a 3” semi-rigid coaxial cable having negligible insertion loss connects it to the spectrum analyzer. Please note that the device is designed to have an output power of +17dBm however a variation of +1, -2dB is anticipated. FCC ID: HCQ3B6ETOEMM EN1941 Plot 4: RF output at the low channel Plot 5: RF output at the middle channel FCC ID: HCQ3B6ETOEMM EN1941 Plot 6: RF output at the high channel Conducted spurious and harmonic emissions measurements: There is no way to measure conducted spurious and harmonic emissions without altering the device. The device was taken to an accredited and listed lab, International Approvals Laboratories, and the relevant radiated measurements were taken using their 3-meter Open-Air Test Site. Average time of occupancy measurement: Section 15.247(a)(1)(i) stated, “...if the 20 dB bandwidth of the hopping channel is 250kHz or greater, the system shall use at least 25 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 10 second period” To effectively obtain this measurement, FCC Public Notice DA 00-705 requires the following spectrum analyzer settings: Span: 0 RBW: 1MHz VBW: 1MHz (VBW ≥ RBW) Sweep: 60ms (as necessary to capture the entire dwell time per hopping channel) Detector: peak Trace: max hold Plot 6 below clearly shows the dwell time is less than the 0.4 seconds required by 15.247(a)(1)(i).
