5015 B. U. Bowman Dr. Buford, GA 30518 December 20, 2012 ACS TCB 5015 B.U. Bowman Drive Buford, GA 30518 Re: FCC ID: SDBSLC20 To Whom It May Concern: The following application is submitted on behalf of our client, Sensus Metering Systems, Inc., for evaluation of their model SLC20 for certification under FCC Part 24 Subpart D and Part 101 Subpart C. The model SLC20, FCC ID: SDBSLC20, is a wireless transceiver module operating from 901MHz - 960 MHz. The model SLC20 is identical to the Sensus model SLC200 (FCC ID: SDBSLC200) from a hardware perspective except that the model SLC200 offers an integral PCB antenna while the model SLC20 has the PCB antenna section snapped off and provides an RF connector for external antennas. Since the SLC20 module is intended to be implemented into specific host devices, it was evaluated for radiated emissions in the orientation of typical installation. The SLC20 was tested in full to the requirements of the aforementioned rules and was found to be in compliance. Sincerely, Sam Wismer Vice President, Technology Advanced Compliance Solutions, Inc.

The system utilizes induction and LED lamps that provide brighter, whiter light and excellent color rendering compared to the dim yellow orange glow offered by older lighting technologies. The SLC20 allows smarter use of resources – ranging from shorter operational hours to virtually imperceptible light reduction during non-critical hours for additional cost savings. The Sensus Lighting Control control board includes an integrated metrology chipset to measure energy consumption for each lamp. The system is comprised of power supply, metrology and radio modules. The Power Supply and Metrology modules are combined to form one module where the radio is separate and usually resides in a different compartment within the luminare. The radio operates from a power source provided by the power supply module and is FlexNet based. Manufacturer Information: Sensus Metering Systems, Inc. 639 Davis Drive Morrisville, NC 27560 Test Sample Serial Numbers: 52000718 Test Sample Condition: The unit was in good operating conditions with no physical damages. 1.3 Test Methodology 1.3.1 Configurations and Justification The unit was powered using a 3.6 VDC power source. The unit provides different modes of operations corresponding to different modulations and where applicable data is provided for the configuration leading to the highest readings. The radiated emissions evaluations were performed with a 50 ohm termination at RF port up to the 10 th harmonic. The unit set in the orientation of typical installation during the testing. The RF conducted measurements were performed directly at the RF port through suitable attenuation. The evaluation for unintentional emission is documented separate…
