pee bs x r u49L SECTION 1 INTRODUCTION 1.1 DESCRIPTION OF EQUIPMENT UNDER TEST (EUT) The Mini—Alarm Transmitter, Model U971, is a wrist—watch—size wireless alarm transmitter used together with the U981 mini—alarm receiver as a mini—alarm system, or in an ordinary telePROTECT 900 alarm system. The unit will only transmit its ID code on command. The U971 alarm transmitter can also be an integrated part in a teleCourier 900 paging system. Alarms are transmitted in the UHF radio band and the code format is compatible with the teleCOURIER 900 paging system. Alarms are actuated by pressing the alarm pushbutton. Different types of alarms can be transmitted, depending on whether the button is pressed once or twice. The type of alarm and pushbutton function are programmed in an internal EEPROM. Maximum range for the battery—operated transmitteris about 100 meters at line of sight when used together with the mini—alarm receiver, US81. The transmitter is approximately 2" round and %" deep. The unit is manufactured by Ascom Tateco. 1.2 MODE OF OPERATION The EUT was transmitting continuously. 1.3 APPLICABLE DOCUMENTS ANSI ©C63.4—1992 "American National Standard for Methods of Measurement May 26, 1996 of Radio—Noise Emissions from Low—Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz" 1SO 10012—1:1992(3) "Quality Assurance Requirements for Measuring April 1, 1996 Equipment Part 1: Metrological Confirmation System for Measuring Equipment" ANSVNCSL Z54001: 1994 "American National Standard for Calibration General July 27, 1994 Requirements — Calibration Laboratories and Measuring and Test Equipment" Code of Federal "Telecommunications, Federal Communications Regulations Commission Radio Frequency Devices" Title 47 Part 15 EMC Science Center, Inc.

peoc uns Bax24u49 11 SECTION 2 TEST FACILITIES 2.1 SCoPE Radiated emission testing was performed at an antenna—to—EUT distance of 3 meters according to the procedures in ANSI C63.4—1992. The open—area test site facility used to collect the radiated emissions data is located at the EMC Science Center, Inc., 20 Clipper Road, West Conshohocken, PA 19428. This site has been fully described in a report submitted to the FCC dated April 29, 1994. 2.2 OQPEN—AREA RADIATED EMISSIONS TEST SITE The radiated emissions test was performed on an open—area test site located adjacent to R & B Enterprises‘ EMI facility. (See Figure 3—1.) The test site was constructed and tested to the recommendations/requirements of ANSI C63.4—1992. The following is a description of the test site. The conducting ground plane measures 56 feet (17 meters) wide by 70 feet (21.3 meters) long and is made up of 1/4—inch square galvanized steel mesh. Copper ground rods are connected to the ground plane at key locations. This size ground plane allows an extension of five meters beyond the antenna tower and is sufficiently wide to that it extends at least five meters beyond the widest horizontally polarized antenna {dipole or biconical). " The receive antennas were placed on a remotely controlled motorized fiberglass antenna positioner located three or ten meters from the EUT. The positioner was capable of positioning the center of the antenna at any height in the range of one to four meters above the ground plane. The positioner was also capable of maintaining the antenna in both horizontal and vertical polarizations. The antenna signals were fed to the EMI receiver located within the building via a shielded cable. The EMI receiver was powered from a common wall socket through an isolation transformer. The EUT was placed on a wooden table with the dimensions of 1.5 meters x 1.0 meter x 0.8 meter high. The table was placed on a remotely controlled turntable, thus allowing emissions to be measured from all sides of the EUT. The EUT is located in a wooded weather protected structure 20 feet wide by 36 feet long and 16—1/2 feet high. The power supplied to the EUT came from a separate power run from the main distribution box through underground PVC conduit. Receptacles were brought above ground via PVC conduit to the center of the turntable. The power was switchable remotely via a switch located at the building power—distribution panel EMC Science Center, Inc. T/A R&B Enterprises Report No. 973942 Revision: —

FSS in lga2r ud +L 2.3 TEST EQUIPMENT 2.3.1 Calibration The calibration due date for each piece of test equipment used was specified on a sticker affixed to its case. All of the test equipment had been calibrated in accordance with the requirements of ISO 10012—1:1992(E) and ANSI/NSL Z54001:1994 using standards directly traceable to the National Institute of Standards and Technology. 2.3.2 Measurement—Receiver Characteristics All radiated emission measurements were made with the EMI! analyzer in the quasi—peak detection mode. The bandwidths for the EMI analyzer were as follows: Frequency Range Bandwidth 150 kHz to 30 MHz 9 kHz 30 MHz to 1000 MHz 120 kHz EMCG Science Center, inc. T/A — R&B Enterprises Report No. 9783942 Revision: —

yc ol [ AxZ u4 7 i SECTION 3 TEST PROCEDURES 3.1 OPEN—AREA RADIATED EMISSIONS TEST PROCEDURE The EUT was configured in a normal operating configuration. Preliminary radiated measurement were performed inside the shielded enclosure at a measurement distance of one meter to determine the emission characteristics of the EUT. The EUT was rotated 360° to determine the configuration that produced the highest level. This procedure was utilized for the final measurement performed. The final radiated emissions test was performed on the open—area site. The measurements were taken with an EUT—to—antenna distance of three meters over the frequency range from 30 MHz to 1000 MHz. The frequency and amplitude of the six highest radiated emissions relative to the limit were recorded as a minimum. The radiated emissions measurements were taken in both the horizontal and vertical polarization of the receive antenna. Also, the receive antenna was varied in height from one to four meters to measure the maximum emissions from the EUT. 3.2 BANDWIDTH OF EMISSIONS TEST PROCEDURE The EUT was mounted on a test board (T971PA) and its output was directly coupled to a spectrum analyzer. The bandwidth was measured 20 dB below the modulated carrier. 3.3 TEST RESULTS 3.3.1 Radiated Emissions The EUT was set up for radiated emissions testing in the open—area test site as shown in Figure 3—1. The EUT complied with FCC Part 15, Subpart C, Section 15.231 requirements. The results of the radiated emissions test are included in Appendix A. 3.3.2 Bandwidth of Emissions The EUT complied with the requirements of Section 15.231(c). EMC ScienceCenter, .Inc.
