DC9EZ-SERIESMicrowave Door Sensor

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 6, 2003 RE: OPTEX CO., LTD. FCC ID: DC9EZ-SERIES I have a few comments on this Application. 1.) Please insert RF Exposure warning under you FCC heading. To read something like: Caution 1. To comply with FCC RF exposure compliance requirements, a separation distance of at least 20cm must be maintained between the antenna of this device and all persons. 2. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2.) Please correct analyzer plots as they have the wrong resolution bandwidth. RBW cannot be less that 1Mhz and VBW must be equal to or greater for all readings over 1 GHz. 3.) CFR Pt. 15.207 Power Line Conducted test on EUT is missing from report. 4.) Please submit Schematics that show component values. 5.) Please submit Occupied Bandwidth plots. 6.) Please confirm radiated tests were preformed on three orthogonal planes? 7.) CFR PT. 15.31(1) states when performing measurements at a distance other than that specified, the results shall be extrapolated to the specified distance using an extrapolation factor of 20 dB/decade (inverse linear-distance for field strength measurements; inverse-linear-distance-squared for power density measurements). Your report doses not show if the distance correction factors on the plots relates to this requirement or not. Please confirm if this is the extrapolation to 3 meters as called for.

July 7, 2003 RE: OPTEX CO., LTD. FCC ID: DC9EZ-SERIES This is reply to your comment on June 6, 2003. 1.) Please insert RF Exposure warning under you FCC heading. To read something like: A1. We’ve already answered this comment on 7/1/2003. 2.) Please correct analyzer plots as they have the wrong resolution bandwidth. RBW cannot be less that 1Mhz and VBW must be equal to or greater for all readings over 1 GHz. A2. Output signal of this transmitter is non-modulation and it is also continuous wave (CW). At this testing, signal level and the spurious is fairly low. Therefore, at signal level testing, we confirmed that there is no change of peak level at RBW=1MHz and VBW=100kHz (VBW is normally higher than RBW, we set VBW=RBW at testing). For reducing the noise floor, RBW and VBW have to be equal to 100kHz. Because if RBW=VBW=1MHz, it is very difficult to measure accurate value with existing measuring instruments. Please see attached “revised test report. pdf”. 3.) CFR Pt. 15.207 Power Line Conducted test on EUT is missing from report. A3. Please refer to additional Test Report “23BE0059-HO-1(FCC15C). pdf”. 4.) Please submit Schematics that show component values. A4. Please refer to attached “Parts list. xls”. 5.) Please submit Occupied Bandwidth plots. A5. Please refer to additional Test Report “23BE0059-HO-1(FCC15C). pdf”. 6.) Please confirm radiated tests were preformed on three orthogonal planes? A6. As you can see in attached “revised test report. pdf” of section 2.5.2, EUT was checked with 3 directions and it is understandable that measurement was performed with the maximum direction. 7.) CFR PT. 15.31(1) states when performing measurements at a distance other than that specified, the results shall be extrapolated to the specified distance using an extrapolation factor of 20 dB/decade (inverse linear-distance for field strength measurements; inverse- linear-distance-squared for power density measurements). Your report doses not show if the distance correction factors on the plots relates to this requirement or not. Please confirm if this is the extrapolation to 3 meters as called for. A7. At this frequency band, it is almost impossible to measure the accurate value at the distance of 3m. By the tested wavelength, we can assume distance of 25cm as Far Field. This Distance Conversion is shown at section 2.4.1 and 2.4.2 of the “revised test report. pdf”. We followed FCC15.31(f)(1) and used 20dB/ decade.

EZ Technical description EZ is a non-contacting switch for opening and closing an automatic door. EZ has a microwave Doppler (MW) detector. When the detector detects a human, the relay output connected to the output terminal is reversed. Moreover, LED is displayed on red. MW detector transmits and receives K-band microwave (24.125 GHz). If there is a moving object in the detection area, it causes changes in received microwave frequency (Doppler effect). MW detector outputs signals when there are such changes. This product is a fixed office and antennas cannot be exchanged. The antenna is a permanent attachment type antenna. Block diagram description MW SENSOR MW SENSOR transmits and receives K-band microwave (24.125 GHz). If there is a moving object in the detection area, it causes changes in received microwave frequency (Doppler effect). MIXER outputs signals when there are such changes. Fundamental microwave frequency is generated by OSC, and Microwave is emitted from the antenna ( Wire zig-zag array antenna ) through MIXER. The reflections of Microwave at objects in the detection area are received at the antenna, and mixed at MIXER with fundamental microwave frequency. If there is a human moving in the detection area, the microwave frequency is added with moving speed of the human for Doppler effect. Then MIXER outputs the Doppler signals (1～300HZ) to AMPLIFIER. ・ AMPLIFIER The Doppler signal outputted from MIXER is amplified. ・ MICROCOMPUTER MICROCOMPUTER judges whether the detection object is entering into detection area with the signal amplified by AMPLIFIER., and it judges whether the detection object is advancing into detection area. The judged result is outputted to RELAY DRIVE and LED DRIVE. ・RELAY DRIVE When a detection signal is inputted, the relay output connected to the output terminal is reversed. ・ LED DRIVE When a detection signal is inputted, red is made to turn on LED for a display. Moreover, if there is no detection signal, LED for a display will be made to turn on green. ・ DC/DC CONVERTER The inputted voltage (AC12-24V, DC12-30V) is changed into voltage required for each BLOCK.
