Radio Dialle, Model: RADD304 complies with the limits for a Periodic Intentional Radiator under Part 15.231 of the FCC Rules and Regulations. 2.0 Description of Equipment Under Test (EUT) The Ness Security Products Pty Ltd. RADD304 Radio Dialler (EUT) is used as part of a security alarm system and provides a wireless link between an SecurityGuard (SG3) alarm panel (FCC ID: O2K-SG3-304) and the Public Switching Telephone Network (PSTN). The Radio Dialler allows the SecurityGuard to report alarms to a central monitoring station via the telephone line. It also provides various control signals to the SecurityGuard alarm panel. Normal operation of the EUT is as follows: The unit receives a signal from the alarm panel transmitter to activate it. Upon activation the unit dials the contracted alarm company central station computer; the computer will answer the call, and send two verification tones. The Radio Dialler then sends its data sequence, and the central station will answer with a confirming tone. The unit is configured with one RJ-11 PSTN jack. The Radio Dialler is powered via a 115VAC adapter that provides 18VAC to the unit. A battery is contained in the unit to provide back-up power in the event of a power failure.

2.1 On-board Oscillators The Ness Security Products Pty Ltd. RADD304 Radio Dialler contains the following oscillators: 10MHz (Microprocessor clock), 32.768kHz, and a 303.825MHz SAW Oscillator. 3.0 Test Configuration The EUT was mounted on a vertical board placed on the turn-table to simulate wall mounting by the consumer. All testing was performed at 120VAC. I/O Ports I/O Cables RJ-11 PSTN port 1 meter, unshielded, unterminated Input power 1.5 meter, unshielded, AC adapter to input power 3.1 Testing Algorithm The transmitter was turned on and setup for providing continuous transmission during testing. Worst case emissions are recorded in the data tables. 3.2 Conducted Emissions Testing The EUT was placed on an 80 cm high 1 x 1.5 m non-conductive table above a ground plane. Power to the EUT was provided through a Solar Corporation 50 Ω/50 µH Line Impedance Stabilization Network bonded to a 3 x 2 meter ground plane. The LISN has its AC input supplied from a filtered AC power source. Power and data cables were moved about to obtain maximum emissions. The 50 Ω output of the LISN was connected to the input of the spectrum analyzer and the emissions in the frequency range of 450 kHz to 30 MHz were measured. The detector function was set to quasi-peak or peak, as appropriate, and the resolution bandwidth during testing was at least 9 kHz, with all post-detector filtering no less than 10 times the resolution bandwidth. 3.3 Radiated Emissions Testing The EUT was placed on an 80 cm high 1 x 1.5 meters non-conductive motorized turntable for radiated testing on a 3 meter open field test site. The emissions from the EUT were measured continuously at every azimuth by rotating the turntable. Biconical and log periodic broadband antennas were mounted on an antenna mast to determine the height of maximum emissions. The height of the antenna was varied between 1 and 4 meters. Cables were varied in position to produce maximum emissions. Both the horizontal and vertical field components were measured. The output from the antenna was connected, via a preamplifier, to the input of the spectrum analyzer. The detector function was set to quasi-peak or peak, as appropriate. The measurement bandwidth on the spectrum analyzer system was set to at least 120 kHz, with all post-detector filtering no less than 10 times the measurement bandwidth. For emissions above 1 GHz, the measurement bandwidth on the spectrum analyzer system was set to at least 1 MHz, with all post-detector filtering no less than 10 times the measurement bandwidth.

3.3.1 Radiated Data Reduction and Reporting To convert the raw spectrum analyzer radiated data into a form that can be compared with the FCC limits, it is necessary to account for various calibration factors that are supplied with the antennas and other measurement accessories. These factors are grouped into a composite antenna factor (AFc) and are supplied in the AFc column of Table 2. The AFc in dB/m and AFd (duty cycle factor) in dBµV (see Exhibit 1) are algebraically added to the Spectrum Analyzer Voltage in dBµV to obtain the Radiated Electric Field in dBµV/m. This level is then compared with the limit. Example: Spectrum Analyzer Voltage: VdBµV Composite Antenna Factor: AFcdB/m Duty Cycle Factor: AFddBµV Electric Field: EdBµV/m = VdBµV + AFcdB/m + AFddBµV To convert to linear units: EµV/m = antilog (EdBµV/m/20) Data is recorded in Table 2.

EXHIBIT 1 DUTY CYCLE CALCULATIONS The following page shows spectrum analyzer plots of the transmitter coding. The following calculations show the worst case 100 ms duty cycle correction used for calculating the average level of the carrier, harmonics, and emissions. Plot 1 shows a continuous pulse train over a 100 ms period with 90 pulses occuring during this time. The width of the pulses are shown in Plot 2 and measured to be 720 us. From these plots, the following worst-case, 100 ms, duty cycle correction factor is calculated. ON TIME PER PULSE TRAIN: (91 x 720 us)= 65.52 ms ON TIME PER 100 ms Pulse Train = 65.52 ms/100 ms = 0.655 Duty Cycle = 65.5% Duty Cycle = -3.7 dB AFd Ness Security Products Pty Ltd.

Appendix A Statement of Measurement Uncertainty For the purposes of the measurements performed by Washington Laboratories, the measurement uncertainty is ±2.3 dB. This has been calculated for a worst-case situation (radiated emissions measurements performed on an open area test site). The following measurement uncertainty calculation is provided: Total Uncertainty = (A2 + B2 + C2)1/2/(n-1) where: A = Antenna calibration uncertainty, in dB = 2 dB B = Spectrum Analyzer uncertainty, in dB = 1 dB C = Site uncertainty, in dB = 4 dB n = number of factors in uncertainty calculation = 3 Thus, Total Uncertainty = 0.5 (22 + 12 + 42)1/2 = ±2.3 dB.
