You will have assurance that they will function properly when you need them most – during a power outage. BattGuard includes the following components: ƒ BattGuard Telesensors – specially designed transceivers that are connected to each battery cell in your backup system and monitor the health of your backup system. The Telesensors measure voltage, current and temperature and transmit the data every 15 minutes using a performance optimized 2.4GHz direct sequence spread spectrum (DSSS) radio. ƒ End-of-String master – special Telesensor that receives the battery data from the Telesensors and provides a radio to serial (PC) interface. ƒ DCU (Data Collection Unit) – laptop computer that collects the following data for each battery: battery current measurements, voltage, and temperature. ƒ BattGuard software – specialized computer program used to configure the Telesensors, graphically display battery data, and export the data for further analysis using other programs such as Microsoft Excel. About This Document This guide includes procedures to help you install and use the BattGuard Battery Monitoring System. Audience Information in this guide is directed to field engineers and technicians, customer engineers, technicians, and contracted installa…

Exhibit 11: RF Exposure/Environmental Section 15.247 (b)(4) Requirement: Spread spectrum devices shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See § 1.1307(b) and 2.1093 of this chapter. All equipment shall be considered to operate in a “general population/uncontrolled” environment. Applications for equipment authorization of devices operating under this section must contain a statement confirming compliance with these requirements for both fundamental emissions and unwanted emissions. Technical information showing the basis for this statement must be submitted to the Commission upon request. Demonstration of Compliance: The 0920 is classified as a mobile device, which is installed so that a minimum separation distance of 20 centimeters in maintained between the transmitter’s radiating structure and the body of the user or nearby persons, and the ERP of the 0920 is less than 50 mWatts. Therefore, the 0920 is categorically excluded from routine environmental evaluation for RF exposure as per § 2.1093. The installation/user manual contains a warning statement that instructs the installer/user that the 20 centimeter separation distance must be maintained in order to comply with the RF exposure requirement.

LXT821B1 Processing Gain Test Results 4/2/02 Processing Gain Measurement: LXT821B1 (Alpine B1) Revised: 2/28/2002 Page 1 of 5 LXT821B1 Processing Gain Test Results 4/2/02 I. Summary This document describes how the processing gain was measured for the Intel LXT821B1 digital spread spectrum telephone transceiver. Included are specifications, test setup, and test results. II. Requirements According to the FCC requirement 15.247 for direct sequence spread spectrum systems, the minimum processing gain is 10 dB. The CW jamming method was used to determine the LXT821B1 processing gain. The processing gain was calculated using the following equation: G p = S/I + J/S + L sys where: G p = Processing Gain S/I = Signal to noise required for a given error probability. In this case 1 x 10 -4 was used. J/S = Jammer to signal ratio required to produce given error probability. L sys = System loss to due non ideal performance. Maximum allowed by the FCC is 2.0 dB. The S/I ratio was determined to be 11.0 dB according to Jakes “Microwave Mobile Communications”. Page 229 indicates the relevant curve showing error probability Vs S/I for a non-coherent FM system with a peak deviation equal to .35 of the modulation frequency: F d = .35 F s . Given a minimum processing gain of 10 dB, the minimum allowable J/S ratio is -3.0 dB. Page 2 of 5 LXT821B1 Processing Gain Test Results 4/2/02 III. Test Setup The processing gain was measured using the test setup shown in Figure 1: DUT: LXT821: Slave Mode RF I/O RF Shielded Enclosure Bit Error Rate Tester Receive Data Signal Generator: 2.439 - 2.442 GHz Tranmit Data Tranmit Data ClockReceived Data Clock Spectrum Analyzer LXT821: Master Mode RF I/O 10 dB Directional Coupler In Out Cpl Step Attenuator: 0 to 120 dB, 1db Steps Power Combiner / Splitter s 12 Master Unit: RF Signal Slave Unit: RF Signal 10 dB Directional Coupler In OutCpl Figure 1: Processing Gain Test Setup The following test equipment was used for this setup: • LDB810 Demonstration system: Used LXT821B1 RFIC’s. • Hewlett Packard ESG D3000A Signal Generator • Hewlett Packard HP8563E Spectrum Analyzer • Hewlett Packard HP 8494A and HP 8496A Step Attenuators • Mini Circuits ZFDC-10-5 10 dB Directional Coupler (2) • Mini Circuits ZFSC-2-4 Power Combiner • Ramsey STE-3000 Shielded Test Enclosure • Telecommunication Techniques Corp. Firebird MC6000 Communication Analyzer (BER tester) with Lab Interface Card • Semflex SMA cables The LDB810 demonstration system was set up at the middle channel 2.4405GHz. The LXT810B base band 3dB bandwidth is less than 1.0 MHz; therefore, the signal generator was used to inject a C / W jammer from 2.439GHz to 2.442GHz in 50 kHz increments. The DUT received input power was set at -50 dBm. The jammer power was adjusted to achieve a bit error rate of 1x10-4 at each jammer frequency. The jammer power was recorded and the processing gain calculated for each jammer frequency from 2.439GHz to 2.442GHz. IV. Test Results The worst case processing gain found for the middle frequency band was 11.4 dB for the jamming frequency of 2.4411GHz, and 11.5dB for the jamming frequency of 2.439.9GHz. This and all Page 3 of 5 LXT821B1 Processing Gain Test Results 4/2/02 other jamming frequencies in the middle of the band (2.439GHz-2.442GHz) pass the minimum requirement of 10dB. All of the measured test data is recorded in : : Channel Frequency (Nominal) = 2440.50 MHz Bit Error Rate = 1.00E-04 Required S/N for BER = 11.0 dB System Losses = 2.0 dB Desired Signal Strength at Receiver (S) = -50.0 dBm Jammer to Signal Ratio Jammer Frequency (MHz) RF Src pwr Jammer Power (J) (dBm) J / S (dB) Processing Gain (dB) 2439.000 -21.80 -28.30 21.7 34.7 2439.050 -22.80 -29.30 20.7 33.7 2439.100 -24.00 -30.50 19.5 32.5 2439.150 -25.20 -31.70 18.3 31.3 2439.200 -26.40 -32.90 17.1 30.1 2439.250 -27.70 -34.20 15.8 28.8 2439.300 -29.10 -35.60 14.4 27.4 2439.350 -30.70 -37.20 12.8 25.8 2439.400 -32.10 -38.60 11.4 24.4 2439.450 -34.40 -40.90 9.1 22.1 2439.500 -36.40 -42.90 7.1 20.1 2439.550 -38.20 -44.70 5.3 18.3 2439.600 -39.90 -46.40 3.6 16.6 2439.650 -41.50 -48.00 2.0 15.0 2439.700 -43.30 -49.80 0.2 13.2 2439.750 -44.20 -50.70 -0.7 12.3 2439.800 -44.50 -51.00 -1.0 12.0 2439.850 -44.80 -51.30 -1.3 11.7 2439.900 -45.00 -51.50 -1.5 11.5 2439.950 -44.90 -51.40 -1.4 11.6 2440.000 -44.70 -51.20 -1.2 11.8 2440.050 -44.70 -51.20 -1.2 11.8 2440.100 -44.70 -51.20 -1.2 11.8 2440.150 -44.50 -51.00 -1.0 12.0 2440.200 -44.20 -50.70 -0.7 12.3 2440.250 -44.20 -50.70 -0.7 12.3 2440.300 -44.00 -50.50 -0.5 12.5 2440.350 -44.00 -50.50 -0.5 12.5 2440.400 -43.90 -50.40 -0.4 12.6 2440.450 -44.10 -50.60 -0.6 12.4 2440.470 -43.20 -49.70 0.3 13.3 2440.480 -42.40 -48.90 1.1 14.1 2440.490 -42.60 -49.10 0.9 13.9 2440.495 -42.80 -49.30 0.7 13.7 Page 4 of 5 LXT821B1 Processing Gain Test Results 4/2/02 2440.500 -42.60 -49.10 0.9 13.9 2440.505 -42.60 -49.10 0.9 13.9 2440.510 -42.80 -49.30 0.7 13.7 2440.520 -43.60 -50.10 -0.1 12.9 2440.530 -43.90 -50.40 -0.4 12.6 2440.550 -43.80 -50.30 -0.3 12.7 2440.600 -42.90 -49.40 0.6 13.6 2440.650 -43.10 -49.60 0.4 13.4 2440.700 -43.40 -49.90 0.1 13.1 2440.750 -43.70 -50.20 -0.2 12.8 2440.800 -44.00 -50.50 -0.5 12.5 2440.850 -44.40 -50.90 -0.9 12.1 2440.900 -44.70 -51.20 -1.2 11.8 2440.950 -44.80 -51.30 -1.3 11.7 2441.000 -45.00 -51.50 -1.5 11.5 2441.050 -45.00 -51.50 -1.5 11.5 2441.100 -45.10 -51.60 -1.6 11.4 2441.150 -44.90 -51.40 -1.4 11.6 2441.200 -44.90 -51.40 -1.4 11.6 2441.250 -43.90 -50.40 -0.4 12.6 2441.300 -42.40 -48.90 1.1 14.1 2441.350 -40.80 -47.30 2.7 15.7 2441.400 -39.00 -45.50 4.5 17.5 2441.450 -37.20 -43.70 6.3 19.3 2441.500 -35.20 -41.70 8.3 21.3 2441.550 -33.20 -39.70 10.3 23.3 2441.600 -31.40 -37.90 12.1 25.1 2441.650 -29.90 -36.40 13.6 26.6 2441.700 -28.10 -34.60 15.4 28.4 2441.750 -26.80 -33.30 16.7 29.7 2441.800 -25.30 -31.80 18.2 31.2 2441.850 -24.10 -30.60 19.4 32.4 2441.900 -22.80 -29.30 20.7 33.7 2441.950 -21.70 -28.20 21.8 34.8 2442.000 -20.60 -27.10 22.9 35.9 11.4 = Minimum Processing Gain 2.…
