FCC ID: 2BDOX-K58S55 K58S55 Microwave Motion Sensor

K58S55 5.8GHz Microwave Motion Sensor K58S55 B K58S55 5.8GHz Microwave Motion Sensor K58S55 is a compact microwave sensor, which is operating at ISM 5.8GHz band. It works on the principle of the Doppler effect. If a movement in the detection zone changes the echo pattern, the sensor responds and generate control signal to switch light on. The compact size, low power consumption, customized detection distance and time delay make K58S55 ideal for scenarios of smart lighting, security monitoring, intelligent control system.

Installation Guide No inductance beneath sensor module as inductance may introduce interference with sensor. Keep power supply as clean as possible. 100uF capacitor is recommended on power supply side. Keep antenna plane at least 3mm away from nearby stuffs. Too big (eg, playground)or too small space (< 2m) shall be avoided as sensors performance might degrade. No metallic stuff in front of antenna.

The host manufacturer installing this module into their product must ensure that the final composit product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation. The host manufacturer has to be aware not to provide informationto the end user regarding how to install or remove this RF module in the user's manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. 2.4 Limited module procedures Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212. 2.5 Trace antenna designs Applicable. 2.6 RF exposure considerations The device can be used in portable exposure condition without restriction and if RF exposure statement or module layout is changed, then the host product manufacturer required to take responsibility of the module through a change in FCC ID or newapplication. The FCC ID of the module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible for re-

evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 2.7 Antennas Antenna Specification are as follows:

Antenna Type:PCB antenna Antenna Gain(Peak):3.5 dBi (Provided by customer) This device is intended only for host manufacturers under the following conditions:

The transmitter module may not be co-located with any other transmitter or antenna;

The module shall be only used with the External antenna(s) that has been originally tested and certified with this module. The antenna must be either permanently attached or employ a uniqueantenna coupler. As long as the conditions above are met, further transmitter test will not be required. However, the host manufacturer is still responsible for testing their end-

product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheralrequirements, etc.). 2.8 Label and compliance information Host product manufacturers need to provide a physical or e-label stating Contains FCC ID: 2BDOX-K58S55 With their finished product. 2.9 Information on test modes and additional testing requirements Operation Frequency:5730~5835MHz Number of Channel:36 Channels Modulation Type:CW Antenna Type:PCB antenna Antenna Gain(Peak):3.5 dBi (Provided by customer) Host manufacturer must perfom test of radiated & conducted emission and spurious emission, etcaccording to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. Only when all the test results of test modes comply with FCC requirements, then the end product canbe sold legally. 2.10 Additional testing, Part 15 Subpart B disclaimer The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247

& 15.207 & 15.209 & 15.205and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
