1 General The LC-171 is unique motion detector utilizing dual passive infra-red elements and Microwave technology for use outdoors and in harsh environments. The LC-171 is designed for outdoor use in the most severe climatic conditions and may also accommodate pets. High reliability is achieved by combining both dual tech hardware with highly sophisticated software and an adaptive coverage area, greatly reducing the possibility of false alarms.
3 Assembly description The LC-171 is a robust detector which includes a large LED indicator that can be easily observed from long distances and an optional buzzer to provide indication of intrusion. Using the supplied mounting bracket, the LC-171 can be easily mounted to walls using mounting screws and poles using the supplied metal bands.
4 Detection Pattern The LC-171 has a 90° top view PIR and MW detection pattern with over 18m detection distance (when installed at 1.2m above the ground surface). The LC-171 has an internal rotating housing (which includes the 2 PIR elements and the MW) that can be adjusted horizontally, so its 90° coverage may vary between 0° and 180°.
5 Selecting mounting location The installation of the LC-171 requires a solid, level base for the mounting bracket and must be located in a manner that when the detector is mounted, it is facing the center of the desired detection zone. The protected area must be free from obstacles like walls, fences, trees, ditches and other microwave detectors. Choose a location most likely to intercept an intruder according to detection pattern on page 5.
6 Detector Installation Important! Prior to installation, read both “Operation” and “Selecting the mounting location” sections carefully. 1. Install the detector in such manner that the intruder 2. The detector is to be installed at height of 0.8 to 1.5 is most likely to cross the detection area from side to meter (ideally 1.2m) side. 3. Make sure to attach the metal bracket to a leveled 4.
9. Break the relevant knockouts on the rear side of the 10. Attach the sealing “U” shaped Sponge Pad to the plastic base and slide the wires from the outside via the wire opening from the rear side after the wires have paths and knockout to the internal side of the detector. been connected and prior to final product affixing to the mounted bracket. 11. Place the detector on the mounting bracket from top 12. Connect the wires to the terminal blocks side down and then lock the screw at the bottom.
7 Terminal Block Connections Terminal 1 - Marked “-” (GND) - Connect to the ground of the Control Panel. Terminal 2 - Marked “+” (+12V) - Connect to a positive Voltage of 9.6 -16Vdc source (usually from the Control Panel) Terminals 3 & 4 - Marked “TAMP” - If a Tamper function is required connect these Terminals to a normally closed 24-Hour Tamper Zone on the Control Panel.
8 Settings & Adjustments 8.1 Detection beam direction The LC-171 detection beam direction may vary between 0º and 180º. In order to change the detection beam direction rotate the internal detection element housing to the desired direction. 8.2 Detection range setting The LC-171 detection range may vary between 3m and 18m, while installed on 1.2m height above the ground surface. Changing the detection range is achieved by sliding the upper detection element up or down.
To adjust for ranges between 3m and 18m slide the detection element up or down to correspond with the desired distance. Each step between 3m and 18m represents 3m of range. Minimum Range (3m, 10ft) Maximum Range (18m, 60ft) 8.3 Sensitivity, Range and Pet immunity Adjustment The calibration of range and sensitivity is performed by a single 16 position rotating switch. There are 3 groups of switch settings grouped according to desired detection range.
Low Risk Noisy Area Very High Risk High Risk Risk F 7m with Pet Immune up to 35kg 0 18m with Pet Immune up to 20kg 1 E 2 D High Risk Very High Risk 3 Noisy Area C Low Risk Risk 4 B Extremely Noisy Area 5 A 6 9 8 Low Risk 7 13m with Pet Immune up to 35kg Risk High Risk Very High Risk Noisy Area Each group is divided to 5 or 6 sub-positions that help to define the environmental condition inside the detection range: • Low risk: very stable environment without interference from parking
8.4 Indications setting ON LED OFF OFF Buzzer ON Factory default setting ON OFF Factory default setting The LC-171 has two types of indicators: 1. LED 2. Buzzer The installer can adjust both indicators operation during detection (ON or OFF) by using switch number “1” for the buzzer and switch number “2” for the LED. When the LED indicator is ON the LED indicator will activate for 1 second each time an intrusion is detected.
9 Operation Note! Connect the LC-171 to a positive Voltage output of 9.6 -16VDC source. Use only a listed power limited source. The detector shall be provided with minimum of 4 hours of standby power from either a listed compatible control unit or power supply. The detector begins a 2 minute warm up period once connected to power. The LED will flash for the first 30 seconds of the warm up period after power up.
10 Test procedure Walk Test IMPORTANT NOTE: Once installed, the unit should be thoroughly tested to verify proper operation and coverage. After installation, the unit should be tested annually by the installer. The end user should be instructed on how to perform a weekly walk test. Ensure that the detector has completed the 2 minute warm up period before walk testing Make sure that the protected area is cleared of all people.
