The sensor can calculate the number of passing people and their direction of travel. RTJSD02 is fixed dir ectly above a doorway using an adhesive, with an installation time of <1 minute. When a person passes through the doorway, the thermopile array registers a temperature change and its trajectory. After processing, the passing direction and the number of persons will be accurately calculated. RTJSD02 only collects information based on temperature changes directly under the sensor. The sensor can not collect any personal or identif ying. Bluetooth Mesh Technology Bluetooth Mesh technology used in RTJSD02 is a global wireless standard for communication between smart devices in industrial automation environments. Bluetooth Mesh technology uses a reliable mesh network to keep devices connected and working together whi le providing excellent battery life. Dynamic Temperature Compensation Dynamic temperature compensation enables RTJSD02 to automatically monitor the ambient temperature and adjust the signal processing algorithms to maintain stability over tempera- ture changes. Real-time Data Reporting and Offline Caching RTJSD02 reports measurement data through the gateway with a delay of less than 100 ms. If the sensor is offline, the data will be cached locally and will transmit all stored data after the network connection is restored. The above data is measured by 9am laboratory, and may be affected by environmental factors. Counting accuracy = (1-the statistical error of people counted by sensors / the actual number of people) x 100% The recommended installation height is between 2m and 2.5m. Installed below 2m or above 2.5m, blind spots will appear and some area cannot be detected. Remember to point the detection probe at the area needed to be probed.Fix the sensor as close as possible to the edge of the door frame. 2-2.5m ≤1.2m Door * * • www.9amtech.com • contact @9amtech.com • 400-037-8109 RTJSD02 NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communica- tions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. RF Exposure Warning Statements: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment shall be installed and operated with minimum distance 20cm between the radiator & body.

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Counting Sensor Model Name RTJSD02 FCC ID 2AVUKRTJSD02 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION P t = -6.309dBm=0.23mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(0.23mW/5mm) .[√2.402GHz)]= 0.07<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
