Wilmington, NC 28412 Manufacturer representative: Mr. Daniel Flohr Equipment covered by this report: Model nos. SHC-G-MR-433 and SHC-G-433 Options covered by this report: None Transmitting Frequency: 433.92 MHz Test specifications: To determine compliance with: FCC, Part 15.231, Subpart B and C, Rules and Regulations, Class B. Test report number: 10-166A-1 Test commenced: April 12, 2010 Test completed: April 26, 2010 Test engineer: Gene Bailey Test Facility: The test facility used to perform these tests is on file with the FCC under registration number 637500 and located at: EMC Testing Laboratories, Inc. 2100 Brandon Trail Suite 101 Alpharetta, GA 30004 EMC Tests, Inc. (770) 475-8819 Test report no. 10-166A Page 4 of 23 Section 2 PRODUCT DESCRIPTION AND TEST SUMMARY Product description: The product covered by this report is a multi-node system that utilizes the transmission of a control signal in a similar manner as those used with alarm systems, door openers, remote switches, etc. The SQR system is comprised of one master control unit, the Gateway, and a number of slave units. The Gateway includes a microcontroller with an Ethernet interface that communicates using Internet protocol to convey control commands from a utility or other entity’s control server to the control modules installed into the premises to actively manage peak demand power usage or other related services. The Gateway communicates with slave modules using a transceiver The Gateway also acts as a receive-only wireless power meter reading device. The Gateway contains a 433 MHz band receiver that receives the current kilowatt reading from compatible residential and commercial power meters, and communicates this information using the Ethernet interface. The integral L-shaped wire antenna. SHC-G-433 is identical to model no. SHC-G-MR-433 except without populating the integrated 915 meter reading receiver. The test results apply only to the products identified on the test report. Test configuration: The equipment under test (EUT) was set-up and configured as specified by the manufacturer as follows: 1- The product was connected to the following support peripherals: A. A Power supply model no. HHA12-1000. 2- The EUT utilized the following cables and were connected as indicated below: A- An Ethernet cable between the product and laptop. B- Two USB cables C- Power cable EMC Tests, Inc. (770) 475-8819 Test report no. 10-166A Page 5 of 23 Product Description and Test Summary ... Worst case transmit duty Cycle: The duty cycle factor used in the calculation of average radiated limits (15.209 (d)) is described below. Maximum transmit time On equals 10mS over a 125 mS period. The worst case Duty Cycle is calculated as follows: (10/100) 100% = 10% In terms of voltage dB: 20 log (10/100) = -20 dB Modifications: The following modifications were required to comply with the radiated emission limits: 1- None Engineering Statement: All measurement data of this test report was taken in accordance with the FCC, Part 15.231, Class B Rules and Regulations and ANSI C63.4-(09) by EMC Testing Laboratories, Inc. located in Alpharetta, Georgia. Although this data is taken under stringent laboratory conditions and to the best of our knowledge, represents accurate data, it must be recognized that emissions from or immunity to this type equipment may be greatly affected by the final installation of the equipment. Therefore, EMC Testing Laboratories, Inc., while supporting the accuracy of the data in this report, takes no responsibility for use of equipment based on these tests. The manufacturer of this equipment must take full responsibility for any field problems which may arise, and agrees that EMC Testing Laboratories, Inc., in performing its functions in accordance with its objectives and purposes, does not assume or undertake to discharge any responsibility of the manufacturer to any other party or parties. Conclusion: With the above-indicated modifications, the product covered by this report has been tested and found to comply with the above-indicated standards.
