DETECTION PATTERNS DT-7550C DUAL TEC ® Motion Sensor Product Information DT-7550C Side View Wide Angle Lens 2 3 1 ON TROUBLE SHOOTING Problem: Red LED is flashing rapidly, trouble relay is actuated. Explanation: The sensor is in one of three conditions: Microwave supervision failure: The sensor continues operating using PIR as the only detection method. When detection occurs on the PIR channel, the alarm relay will latch open until the Microwave trouble is removed. PIR self-test failure: Alarm relay does not actuate. Temperature compensation failure: When alarm occurs, the alarm relay will latch open until the trouble is cleared. Solution: Power down the sensor or enter zone finder mode which will perform self-test. If the trouble does not clear, replace the sensor. Problem: Trouble relay is actuated without red LED flashing. Explanation: Anti-mask condition is detected. Solution: Verify that the sensor is not masked or blocked. Walk through the detection pattern. Replace the sensor if it does not clear. MASK UNCTIONS The DT-7550C detects a variety of masking materials and objects. When it determines the presence of a mask, the DT-7550C sensor signals a trouble condition. Mask materials may be detected up to one foot from the sensor. A visual inspection and walk-test is recommended for all trouble signals. The sensor clears a mask condition when it detects motion on the PIR and microwave technologies. Refer to the Trouble =unction chart for sensor operation.

Below are the answers to each of the question (Answer is right below each question). -----Original Message----- From: certadm [mailto:[email protected]] Sent: None To: [email protected] Cc: [email protected] Subject: C & K SYSTEMS, INC., FCC ID:C2D7KULP, AN01T1153 Notice_content ------------- Question #1: Test report is written for FCC Class II permissive change. However, the proposed FCC ID number has not been certified by the Commissions . Please revise the test report and confirm the application is intended for Original Application. --- Yes, This report is intended for Original Application. And we already revise the report to reflect this factor. Question #2: Several emission plots were provided with this application. They are ( Pulse repition rate ), (Transmission period plots) and ( output power measurement). Please explain the purpose of these data in relation to FCC technical requirements. --- The extra plots is intended to be use for Pulse signal duty cycle correction purpose, but since the original data already passed the limit, we decided not to claim for this extra relieve and the attached data plots is for your reference only. Question #3: Page 7 of test report, please indicate the detector function used. --- The detector function used is peak detector with RBW=1M and VBW=1M as specified on page 5. Question #4: Please provide spectrum plots to demonstrate 15.245(b)(3) compliance. --- According to 15.245(b)(3), emissions radiated outside of the specified bands, except for harmonics, shall be attenuated by at least 50dB below the level of the fundamental or to the general radiated emission limits in 15.209 whichever is the lesser attenuation. Because of the high frequency nature, the noise floor is quit high compare to the low level fundamental and 50 dBc dynamic range is not able to be maintained with our test setup. Hence we decided to measure the field strength and compared it to 15.209 instead of compare to -50dBc spec. The test result from 30M to 2G was reported in attached file "radiated emissions.PDF" and frequency from 2G to 100 G had been manual checked and only the fundamental emission was founded and recorded in page 7. As mentioned above, we did this part by radiated method( not direct conducted measurement method), so there is no plot we can show you. However, from the tabulated data attached we believe you shall have enough information to prove the compliance. Best Regards Mike Kuo / TCB Certifier The items indicated above must be submitted before processing can cont inue on the above referenced application. Failure to provide the reques ted information within 60 days of the original e-mail date may result i n application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence shoul d be directed to the e-mail address listed below the name of the sender .

PROPOSED FCC ID LABEL AND LOCATION C & K SYSTEMS, INC. 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. FCC ID: C2D7KuLP FCC ID LABEL LOCATION

Description of Operation Model: DT-7550C Variant Models: DT-7450C, DT-7450, DT-7435C, DT-7435, and DT-7425. DT-7500 The DT-7500 series intrusion detection units are motion detection devices which incorporate both Microwave & Passive Infrared detection technologies to sense volumetric motion within a given area. The design is microprocessor based. Functions supported by the microprocessor include Anti-Mask/Anti-Sabotage, Queue Event Logic, Diagnostics, Selectable Sensitivity, Single-Tec Operation, Digital Microwave Interference Filter, Digital Adaptive Microwave Threshold, Adaptive baselines, and “True Temperature Compensation”. The design exhibits exceptional catch performance and false alarm immunity. Overview The Microwave detection transceiver device operates in the “K” band (24.125 or 24.200 GHz). Motion is sensed when the frequency of the reflected return signal, within the volumetric area of view, is different from that of the transmitted waveform. Internal filtering components are included to reject / ignore reflected frequency changes above 500Hz. Range adjustment is provided via potentiometer R8, the Microwave detection pattern increases when adjusted clockwise. Passive Infrared detection occurs when the pyroelectric detector circuitry senses a change in temperature of a target versus background within the optical field of view. Temperature compensation circuitry is provided to vary the sensitivity of the PIR detection component, sensitivity is greatest when ambient temperature at the detector is 93° F to 95° F. PIR detection / trigger adjustment is provided via dual option pulse count control located at SW1-1. Optical resolution of the PIR detection area is viewed via a Fresnel lens. The output of the M.W. & PIR detection elements is input into a micro-controller-based signal processing circuit. Detection by either sensing technology will initiate a timer at the signal processing circuit, if the opposite detection technology senses movement with in this detection window an alarm condition is issued. Filtering & timing parameters within the signal processing unit analyses the detection input to verify that the energy level of the detected stimulus matches the characteristics of human movement Upon alarm condition, the signal processor output de-energizes the alarm relay circuit & energizes the alarm LED indicator. A Normally Closed Tamper switch is provided to indicate separation of the Top / Front housing component from the Base / Rear (mounted) housing Component. Automatic and installer self-test functions are integrated into the micro-controller operation Anti-masking Features The DT-7500 series sensor triggers a trouble signal if covered by an object that reflects a microwave signal up to 24” from the detector. These are the technologies that make this feature work: Power-up Anti-mask The sensor checks for normal activity on both technologies following the Start-up Test Mode (110 seconds). This activity is not timed, once both technologies have been verified for normal operation, the Power-up anti-mask test is complete. If the power-up anti-mask fails the sensor activates the trouble relay. Standard Anti-mask The sensor activates the trouble relay when a mask condition is detected. A mask condition is cleared by subsequent PIR and microwave activity. Diagnostic Self Testing The DT-7500 incorporates three internal self-test functions; these self-test functions are performed at detector power-up, manually via shorting of “Installer Test” pads located below R8, and at the intervals listed below. Microwave Supervision: Monitors the MW circuit functions continuously. PIR Self-Test: Injects a transient pulse into the PIR circuit to verify the amplifier channel once an hour. Temperature: Monitors thermistor circuit “True-Temperature Compensation” function every 30 seconds. The following responses are initiated upon detection of a self-test failure Test Failure Sensor Response Microwave Supervision Failure The sensor opens the trouble relay, continues operating using PIR as the only detection method, and the RED LED flashes rapidly. When detection occurs on the PIR channel, the alarm relay will latch open until the Microwave trouble is removed. If the trouble is not cleared by an internal self-test, the unit will need to be replaced. PIR Self-test Failure The sensor opens the trouble relay and flashes RED LED rapidly. If the trouble is not cleared by an internal self-test, the unit will need to be replaced. During this failure the sensor cannot signal an alarm event. Temperature Failure The sensor will open the trouble relay and flash the RED LED rapidly. When an alarm occurs, the alarm relay will latch open until the trouble is cleared. If the trouble is not cleared by an internal self-test, the unit will need to be replaced. Control Functions Switch SW1 Sensitivity – SW1 position 1 Switch 1 Off, sets the PIR is set to low sensitivity, pulse count 2. This setting is optimized for harsh environments. When switch 1 is On, the PIR is set to high sensitivity, pulse count 1. This setting allows for optimum catch performance. LED Enable/Disable – SW1 position 2 When switch 2 is Off, the LED is completely disabled except for the following conditions: during the power-up sequence, when a diagnostic failure occurs, or during a manually initiated self-test and zone finder. That is, if the switch is off and zone finder mode is used, the LED will automatically be disabled after 10 minutes. When switch 2 is On, the LED displays sensor status. The RED LED will light for 5 seconds on every Alarm trigger; the GREEN LED will light for 1 second on every PIR trigger; and the YELLOW LED will light for 2 seconds on every Microwave trigger. A rapidly flashing RED LED indicates a self-test failure. 50 Hz / 60 Hz Fluorescent Light Filter – SW1 position 3 When switch 3 is Off, the sensor signal processing is set to reject 60 Hz fluorescent light interference. When switch 3 is On, the sensor signal processi…
