EXHIBIT 5-3A CFS8DLWFZW / 573F-WFZW MPE CALCULATIONS - FCC 1.0 APPLICANT: DATE: 6/1/2018 NAME OF APPLICANT: HONEYWELL INTERNATIONAL INC. FCC ID: CFS8DLWFZW 2.0 FCC RULES CONCERNING MAXIMUM PERMISSIBLE RF EXPOSURE: § CFR 47 1.1310 Radiofrequency radiation exposure limits. The criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in § 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of § 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC’s OST/OET Bulletin Number 65, ‘‘Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.’’ NOTE TO INTRODUCTORY PARAGRAPH: These limits are generally based on recommended exposure guidelines published by the National Council on Radiation Protection and Measurements (NCRP) in ‘‘Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,’’ NCRP Report No. 86, Sections 17.4.1, 17.4.1.1, 17.4.2 and 17.4.3. Copyright NCRP, 1986, Bethesda, Maryland 20814. In the frequency range from 100 MHz to 1500 MHz, exposure limits for field strength and power density are also generally based on guidelines recommended by the American National Standards Institute (ANSI) in Section 4.1 of ‘‘IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,’’ ANSI/IEEE C95.1–1992, Copyright 1992 by the Institute of Electrical and Electronics Engineers. 3.0 UUT POWER OUTPUT AND ANTENNA GAIN Z-Wave Ant 1: 2.46 dBi Wi-Fi Ant 1: 1.86 dBi, Ant 2: 1.05 dBi => Max = 1.86 dBi 3.1 MPE CALCULATIONS: FCC GENERAL POPULATION / UNCONTROLED EXPOSURE LIMITS: FOR 300 MHz to 1,500 MHz use F / 1500 mW/cm 2; (§1.1310(e)) FOR 1,500 to 100,000 MHz use 1 mW/cm 2; (§1.1310(e)) EQUATIONS: MAX AVG EIRP (mW) = 10{(MAX COND PWR. + ANT GAIN + DUTY FACTOR)/10)} THE FRIIS TRANSMISSION EQUATION = EIRP X DUTY CYCLE / ( 4 X PI X 20 CM 2 ) MEASURED POWER: - FOR Wi-Fi RADIO, MAX MEAS. PEAK POWER = 22.29 dBm. - FOR Z-Wave RADIO, MAX MEAS. FIELD STRENGTH = 73 dBuV/m @ 3m, which equates to -22.23 dBm EIRP. Correcting for a min antenna gain of 2.46dBi makes the actual EIRP = -22.23 dBm - 2.46 dBi = -24.69 dBm. CALCULATIONS: BANDS AND FCC IDs BAND FCC ID ALL CFS8DLWFZW MAX COND.

IC NUMBER: 573-WFZW 2.0 IC RULES CONCERNING MAXIMUM PERMISSIBLE RF EXPOSURE: RSS-102 § 2.5.2 Exemption Limits for Routine Evaluation - RF Exposure Evaluation. RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: • at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; In these cases, the information contained in the RF exposure technical brief may be limited to information that demonstrates how the e.i.r.p. was derived. 3.0 UUT POWER OUTPUT AND ANTENNA GAIN Z-Wave Ant 1: 2.46 dBi Wi-Fi Ant 1: 1.86 dBi, Ant 2: 1.05 dBi => Max = 1.86 dBi 3.1 MPE CALCULATIONS: IC GENERAL POPULATION / UNCONTROLED EXPOSURE LIMITS: FROM 300 MHz to 6 GHz use (1.31 x 10-2) x f 0.6834 for max field strength (W/m 2) EQUATIONS: MAX AVG EIRP (mW) = 10{(MAX COND PWR. + ANT GAIN + DUTY FACTOR)/10)} THE FRIIS TRANSMISSION EQUATION = EIRP X DUTY CYCLE / ( 4 X PI X 20 CM 2 ) MEASURED POWER: - FOR Wi-Fi RADIO, MAX MEAS.
