1 General
The LC-171 is unique motion detector utilizing four 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.
The active elements are comprised of a dual PIR and advanced Microwave detector inside a
stylish, rigid plastic body.
This special optics combined with state of the art microwave Doppler sensor assures elimination
of “false alarms” while maintaining high security standards for the detection of human intruders
into the protected area.
The detection sensitivity and range is controlled by a digital rotary switch allowing 16 calibration
levels, so that the correct detection pattern will be set for every installation.
The LC-171 is designed to protect large areas and can easily be installed on walls or poles in
order to provide a solid area of protection while rejecting interference from birds and small
animals due to the provided pet immunity optics.

4 Detection Pattern
The LC-171 has a 90°top view PIR and MW detection pattern with over 12m (39 ft.)
detection distance (when installed at 1.2m (4 ft.) 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°.
The LC-171 can differentiate between pets and human bodies and alert accordingly by
having microwave movement detection combined with two PIR detection beams:.
A. Lower PIR element which is fixed to 12m (39ft.) range and 60cm (2ft) above ground level
which helps avoiding pet detection over the entire area.
B. Upper PIR element which has adaptive range between 3 and 12m (10 and 39 ft).
An intrusion is defined by both PIR detection beams being crossed and a Microwave detection
occurring, causing an alarm.
No alarm will be generated if only one of the PIR detection beams is crossed and microwave
detection occurs.

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.
It is recommended that the detector will face
a solid border limiting the detection area, such as the
building structure or fencing wall, to avoid undesired detection
range.
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.
Avoid the Following Installation Locations:
•Facing direct sunlight.
•Facing areas subject to rapid temperature changes.
•Mounted at more than 10º from the vertical or horizontal plane.
•Facing metal doors.
•Near direct sources of heat or airflow.
•Clear all physical obstacles from the detection area
(e.g. plants, laundry, etc.)
•Clear all light reflecting surfaces from the detection area,
including puddles or other standing water.
•Avoid installation on the following types of ground:
Thick vegetation, Grass (un-mown), Water, Sand and Metal.
NOTES:
•Recommended installation height is 1.2m (4ft).
•The DUAL (Four Elements) high quality sensor detects motion crossing the beam; it is less
sensitive detecting motion towards the detector.
•The LC-171 performs best when provided with a constant and stable environment.
•In order to ensure suitable operation of the LC-171 type of ground should be one of the
following: Asphalt concrete, Cement, Soil, Clay, Gravel or Grass (mown).
•Sensitivity adjustment may be required upon extreme temperature changes.
Extremely high temperature will reduce detection range.
Extremely low temperature will increase detection range.
Choose proper installation location to avoid resetting.

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 (10 ft) and 12m (39 ft), while installed on
1.2m (4 ft.) height above the ground surface.
Changing the detection range is achieved by sliding the upper detection element up or
down.
firealarmresources.com

11
To adjust for ranges between 3m and 12m (10 and 39 ft.) slide the detection element up or
down to correspond with the desired distance. Each step between 3m and 12m (10 and
39ft.) represents 3m (10ft) of range.
Maximum Range (12m, 39ft) Minimum Range (3m, 10ft)
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.
Each group is divided into several levels of sensitivity according to the installation
environment.
The sensitivity is determined by a single 16 position rotating switch. Changing the
sensitivity affects immunity to environmental noises, and also affects the detection distance
and pet immunity level.
The rotating switch is marked with digits from “0” to “9” and following letters from “A” to “F”.
Position “0” is maximum sensitivity and “F” is minimum sensitivity.
Note: Adjust sensitivity according to environmental conditions!
Group A - positions 0 – 5 – set sensitivity for 12m detection range with immunity to pets weight
up to 20kg
Group B - positions 6 – A – set sensitivity for 10m detection range with immunity to pets weight
up to 35kg
Group C - positions B – F – set sensitivity for 7m detection range with immunity to pets weight
up to 35kg
NOTE: Ensure that you select the group with a range corresponding to or slightly higher then
the range set in 8.2. Do not select a group setting that has a lower range then the range set in
8.2.

8.4 Indications 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. When the
LED indicator is OFF the LED will not be used to indicate an intrusion has occurred.
When the Buzzer indicator is ON the Buzzer will activate for 1.8sec each time an intrusion is
detected. When the Buzzer indicator is OFF the buzzer will not be used to indicate an intrusion
has occurred. (Setting the buzzer ON gives the installer the ability to have audible
confirmation of intrusion detection during the adjustments and a walk test. After completing
adjustments and walk testing it is recommended to switch the buzzer OFF)
•Place the top cover to the base and close it using the bottom screw.

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.
Create motion in the entire area where coverage is desired by walking perpendicular to the
detection pattern.
Listen to ALARM sound whenever motion is detected (the red LED also turns ON whenever
motion is detected).
Allow 5 sec. between each test for the detector to stabilize.
Walk across the entire area where coverage is desired. Should the coverage be incomplete,
readjust coverage range or relocate the detector.
Once coverage is as desired, the buzzer and LED should be disabled.
