It can detect whether a person present and effectively measure the duration of time they remain. Bluetooth Mesh technolo gy used in RTCZA04 is a global wireless standard for communication between smart devices and anti-theft systems in industrial automation environments. Bluetooth Mesh technology uses a reliable mesh network to keep devices connect- ed and working together while providing excellent battery life. Dynamic Temperature Compensation Dynamic temperature compensation enables RTCZA04 to automatically monitor the ambient temperature and adjust the signal processing algorithms to maintain normal sensing perfor- mance in varying temperatures. Active White Light Suppression Strong sources of white light can interfere with the senses opera- tion. However, the RTCZA04 can actively identify and measure the amount of interfering light allowing for internal processes to remove such noise from the data. Real-time Data Reporting and Offline Caching RTCZA04 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 transmitted after the network connection is restored. Measurement Accuracy=(1-the statistical error of time recorded by sensors /the actual time of measurement)x100% The above data is measured by 9am laboratory, and may be affected by environmental factors. • www.9amtech.com • [email protected] • 400-037-8109 * * Recommended installation location: Install 10-25 cm from the edge of the desk, directly in front of where people sit. If it is installed outside of these limits blind spots will appear. Reme mber to point the detection probe at the area needed to be probed. Installation Guide 10-25cm ≤50cm 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. * Recommended installation location:

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Occupy Sensor Model Name RTCZA04, RTCZ FCC ID 2AVUKRTCZA04 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 = -1.519dBm=0.70mW 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=(0.70mW /5mm) .[√2.480GHz)]= 0.22<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
