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 interfer- ence that may cause undesired operation. No hidden fees As a wireless sensor, there are no power or signal cables to run. The sensor uses standard and easily replaceable AA batteries with reliable usage for up to 5 years. The battery life is viewable within the Optergy ecosystem. No special software license needed to operate. 5 minutes (CO) if using 1.5v batteries, or 1 minute if using 3.6v batteries. 5 seconds (Temperature & Humidity) Wireless Temperature, Humidity and CO Sensor (BW-THCO-M) Up to seven BW-THCO-M wireless sensors can be connected to one BG-1100-M transceiver. Multi-sensor Connectivity Wireless Multi-sensor Connectivity 3 in (78mm) 5 in (128mm) TOP FRONT 1.1in (29mm) DIMENSIONS The BW-THCO-M device requires four AA batteries (not included). We recommend using high-quality, leak-proof alkaline batteries for optimal performance. Although the product will function with regular, good-quality alkaline batteries, the best performance can be achieved by using good-quality lithium batteries with a voltage of either 1.5V or 3.6V. *Rechargeable batteries are not reccomended. ACCESSORIES (BY OTHERS) AA Batteries (1.5V or 3.6V) The sensor poi nt s (te mperature, humidity & CO level) are instant iate d by the Opte rg y P864. These points are reserved for wireless sensors and will have BACnet values corresponding to the device instance of the Optergy P864. The reserved points include: Temperature Value (Deg F or Deg C) Humidity Value (%rH) Carbon Monoxide Value (ppm) Batte ry Level Low Batte ry Level Warni ng Sensor Online Sensor Paired BACNET POINTS Optergy | www.optergy.com | [email protected] BW-THCO-M-DSRev1.0 © 2021-2023 OptergyAll specifi cations are subject to change without notice. The Optergy Air BW-THCO-M sensor pairs with the Optergy Air Transceiver (BG-1000-M). Up to seven (7) Optergy Air BW-THCO-M sensors can be connected to one Optergy Air Transceiver (BG-1000-M). Alternatively, the Optergy Air BW-THCO-M sensor can be connected to the Optergy Air Transceiver (BG-1000-M) in an ecosystem with a mixture of other Optergy Air sensors for a total of seven (7) Optergy Air sensors per one (1) Optergy Air Transceiver (BG-1000-M). When used in conjunction with the P864 and the BG-1000-M, this device will transmit space temperature, humidity, and carbon monoxide values to the BACnet system. The data points for these values are associated with the connected device. The following BACnet points are included: Power and Communication Optergy Air Transceiver (BG-1000-M) Wireless Optergy Air Temperature, Humidity & CO Sensor (BW-THCO-M) 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. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 communications. 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. FCC Radiation Exposure statement The device has been evaluatec to meel general RF exposure requirement. The device can be used in portable exposure condition without restriction.

FCC ID: 2BKJI- BW-THCO-M RF Exposure Evaluation According to KDB 447498 D01 V06 and part 2.1093，Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 The result is rounded to one decimal place for comparison EIRP=E Meas +20log(d Meas )-104.7 EIRP is the equivalent isotropically radiated power, in dBm E Meas is the field strength of the emission at the measurement distance, in dBμV/m d Meas is the measurement distance, in m Here, Field strength (dBuV/m) EIRP (dBm) Max tune-up (mW) Frequency (MHz) Min. distance(mm) Calc. thresholds limit 84.34 -10.82 0.08 2480 5 0.03 3.0 So a SAR test is not required
