PRODUCT DESCRIPTION 2017-1-25 Client and Equipment Under Evaluation Information Company Name: Schweitzer Engineering Laboratories, Inc. Address: 2350 NE Hopkins Court City, State, Zip: Pullman, WA 99163 Evaluation Requested By: Miralem Cosic Model: SEL-FT50 Date of Evaluation: March 24, 2017 Information Provided by the Party Requesting the Evaluation Functional Description of the Equipment: The FT50 Power Line Overhead Fault Detection sensor with a DTS radio operating in the 902 - 928 MHz band. If there is a fault on the power line the transmitter will send a message to an FR12 receiver. One FR12 receiver can listen to 12 FR50 units at a time. Each FT50 unit has its center frequency at a different frequency in the band. The center frequency is determined by the Unit ID and Network ID of the unit. FT50 also sends out a heartbeat message every 15-30 seconds. Objective: To demonstrate compliance with FCC requirements for RF exposure for 2.1091 mobile devices Report No. SCHW0215.3 7/9

MAXIMUM PERMISSIBLE EXPOSURE (MPE) EXRPT.2017.03.16 OVERVIEW Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. ANSI C95.1:2005 + Amd 1:2010 specifies a minimum separation distance of 20 cm for performing reliable field measurements to determine adherence to MPE limits. If the minimum separation distance between a transmitter and nearby persons is more than 20 cm under normal operating conditions, compliance with MPE limits may be determined at such distance from the transmitter. When applicable, operation instructions and prominent warning labels may be used to alert the exposed persons to maintain a specified distance from the transmitter or to limit their exposure durations and usage conditions to ensure compliance. If the use of warning labels on a transmitter is not effective or desirable, the alternative of performing SAR evaluation with the device at its closest range to persons under normal operating conditions may be used. The field strength and power density limits adopted by the FCC are based on whole-body averaged exposure and the assumption of RF field levels relate most accurately to estimating whole-body averaged SAR. This means some local values of exposures exceeding the stated field strength and power density limits may not necessarily imply non-compliance if the spatial average of spatially averaged RF fields over the exposed portions of a person’s body does not exceed the limits. COMPLIANCE WITH FCC 2.1091 “Mobile devices that operate in the Cellular Radiotelephone Service, the Personal Communications Services, the Satellite Communications Services, the General Wireless Communications Service, the Wireless Communications Service, the Maritime Services and the Specialized Mobile Radio Service authorized under subpart H of part 22 of this chapter, parts 24, 25, 26 and 27 of this chapter, part 80 of this chapter (ship earth stations devices only) and part 90 of this chapter are subject to routine environmental evaluation for RF exposure prior to equipment authorization or use if they operate at frequencies of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 watts or more, or if they operate at frequencies above 1.5 GHz and their ERP is 3 watts or more. Unlicensed personal communications service devices, unlicensed millimeter wave devices and unlicensed NII devices authorized under §§15.253, 15.255, and 15.257, and subparts D and E of part 15 of this chapter are also subject to routine environmental evaluation for RF exposure prior to equipment authorization or use if their ERP is 3 watts or more or if they meet the definition of a portable device as specified in §2.1093(b) requiring evaluation under the provisions of that section. All other mobile and unlicensed transmitting devices are categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use, except as specified in §§1.1307(c) and 1.1307(d) of this chapter. Applications for equipment authorization of mobile and unlicensed transmitting devices subject to routine environmental evaluation must contain a statement confirming compliance with the limits specified in paragraph (d) of this section as part of their application.” The device will only be used with a separation distance between the antenna and the body of the user or nearby persons as shown in the table below and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b). COMPLIANCE WITH FCC KDB 447498 D01 General RF Exposure Guidance v06 "KDB 447498 D01 General RF Exposure Guidance v06" provides the procedures, requirements, and authorization policies for mobile and portable devices. Devices operating in standalone mobile device exposure conditions may contain a single transmitter or multiple transmitters that do not transmit simultaneously are covered in section 7.1. Devices containing multiple transmitters capable of simultaneous transmissions are covered in section 7.2. Report No. SCHW0215.3 8/9

MAXIMUM PERMISSIBLE EXPOSURE (MPE) EXRPT.2017.03.16 LIMITS Limits for General Population /Uncontrolled Exposure: 47 CFR 1.1310 Electric Field Magnetic Field Frequency Range Strength Strength Power Density Averaging Time 2 (MHz) (V/m) (A/m) (mW/cm ) (minutes) 0.3 - 1.34 614 1.63 *(100) 30 1.34 - 30 824/f 2.19/f *(180/f2) 30 30 - 300 27.5 0.073 0.2 30 300 - 1500 f/1500 30 1500 - 100000 1 30 f = frequency in MHz * = Plane-wave equivalent power density ASSESSMENT The exposure level for the radio is evaluated at a 20 cm distance from the radio’s transmitting antenna using the general equation: P *G S  4* * R 2 Where: S = power density (mW/cm2) P = power input to the antenna (mW) G = numeric power gain relative to an isotropic radiator R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates) P*G = EIRP Solving for S, the maximum power density 20 cm from the transmitting antenna is determined. This level is then compared to the applicable limit for the transmit frequency. If limits were not met at the 20 cm boundary the evaluation distance is increased until the limit is met as shown in the table below. For co-located radios, the ratio of the calculated level to the limit is determined. The ratios for each co-located radio are summed. If the sum is less than or equal to one, then the device is excluded from testing and is deemed compliant. The standalone MPE and summed MPE ratios are summarized in the following table: Transmit Highest Minimum Measured Conducted Duty Minimum Antenna Power Density Limit Radio Frequency Antenna Gain Separation Compliant Output Power (mW) Cycle Cable Loss (dB) (mW/cm2) (mW/cm2) (MHz) (dBi) Distance (cm) 902-928MHz DTS 904 428.3 1 2.32 0 20 0.145 0.6 Yes Transceiver Report No. SCHW0215.3 9/9
