working principle description The XHS7-2001-WHT is a Smart Window / Door Sensor. It contains an RF module: CBU. Power with DC 2*1.5V AAA batteries. CBU is a Wi-Fi+BT module which supports 2.4GHz only with 802.11b/g/n , BLE 1M mode. It has a simple MCU BK7231N with 3.3v DC power supply and once power on, it could connect the AP or station directly. This module works with a 26MHz crystal, and has a 2MB flash, 5 PWM，1ADC interface. Besides these, it can apply with 2.4GHz PCB antenna or external antenna. The basic function description is as below: Modulation Technique: 802.11b: DSSS (CCK, QPSK, BPSK) 802.11g/n (HT20, HT40): OFDM (64QAM, 16QAM, QPSK, BPSK) BLE: GFSK Antenna Type: PCB Antenna Antenna Gain: 2.21dBi Crystal: 26MHz Frequency Range BLE: 2402-2480MHz Wi-Fi: 2412-2462MHz

Report No.: RA221129-57878E-RF-00 Version 12: 2021-11-09 Page 12 of 64 FCC- BLE&2.4G Wi-Fi FCC §15.247 (i) & §1.1307 (b) (3) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 15.247 (i) and subpart 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines. According to KDB 447498 D04 Interim General RF Exposure Guidance MPE-Based Exemption: General frequency and separation-distance dependent MPE-based effective radiated power(ERP) thresholds are in Table B.1 [Table 1 of § 1.1307(b)(1)(i)(C)] to support an exemptionfrom further evaluation from 300 kHz through 100 GHz. Ris the minimum separation distance in meters f = frequency in MHz For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Shenzhen Accurate Technology Co., Ltd.

The tune up conducted power and antenna gain was declared by the applicant. 2. The BLE can transmit at the same time with the Wi-Fi. Simultaneous transmitting consideration (worst case): The ratio=ERP BLE /limit+ERP Wi-Fi /limit=2.27/768+20.23/768=0.029＜1.0, so simultaneous exposure is compliant. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant.
