1 General
The LC-151 is a unique motion detector utilizing a single (two elements) passive infra-red
element and Microwave technology for use outdoors in harsh environments.
The LC-151 is designed for outdoor use in the most severe and climatic conditions
and may also accommodate pets with the addition of optional pet immunity lenses.
High reliability is achieved by combining both dual tech hardware with highly sophisticated
software, greatly reducing the possibility of false alarms.
The active elements are comprised of a single (two elements) PIR and advanced Microwave
detector inside a stylish, rigid plastic body.
These special optics combined with a 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 potentiometer allowing fine tuning, so that
the correct detection pattern will be set for every installation.
The LC-151 is designed to protect large areas and can easily be installed on walls in order to
provide a solid protection of the area while rejects interferences from birds and small animals due
to the optional “PET MASK” optics.

4 Detection Pattern
The LC-151 has a 90° top view PIR and MW detection pattern with over 15m (49 ft) detection
distance (when installed at 2.4m (7.8 ft) above the ground surface).
Standard Lens
EN

6
LC-L1-15X Corridor Lens (sold separately)
The LC-151 can differentiate between pets and human bodies and alert accordingly by
utilizing microwave movement detection combined with a PIR detection beam.
An intrusion is defined by the PIR detection beam being crossed and a microwave detection
occurring, causing an alarm.
No alarm will be generated if only the PIR detection beam is crossed or if only a microwave
detection occurs.

7
5 Selecting mounting location
The installation of the LC-151 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 2.1m (6.8 ft).
•The PIR sensor detects motion crossing the beam; it is less sensitive detecting motion
towards the detector.
•The LC-151 performs best when provided with a constant and stable environment.
•In order to ensure suitable operation of the LC-151, the 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.

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 is
most likely to cross the detection area from side to side.
2. The detector is to be installed at height of 1.8 to 2.4
meters (5.9 to 7.8 ft) , ideally 2.1m (6.8 ft)
3. Make sure to attach the metal bracket to a leveled
straight and firm wall, leaving 10cm (3.9 inches) from
the top and 10cm (3.9 inches) from both sides, for easy
installation and maintenance.
4. Placing the detector on perpendicular wall is
required for guarding a side window opening.
Alternately the LC-B1-15X Outdoor Mounting bracket
can be installed on the same wall, allowing the
detector beam to be rotated towards the window.
5. Open the detector unwinding the bottom screw.
6. Release the rear metal bracket by unwinding
internal bottom screw.

9
7. Release the detector body from the metal bracket by
pulling the detector up and out.
8. Attach the rear bracket to the wall using mounting
screws.
9. Insert wires through provided access hole and wiring
channels.
10. Attach the sealing sponge pad to the wire opening
from the rear side after the wires have been
connected and prior to final product affixing to the
mounted bracket.
11. Place the detector on the mounting bracket from top
side down and then lock the screw at the bottom.
12. If Pet immunity up to 15kg (33lb) is desired do not
install the LC-F1-15X mechanical pet filter.
If Pet immunity up to 36kg (80lb) is desired install the
LC-F1-15X mechanical pet filter.

8 Settings & Adjustments
8.1 Detection beam direction
The LC-151 detection beam direction is fixed. As a result, it is recommended to
face the intrusion area with the detector.
8.2 Detection beam range setting
The detection range may be set by tilting the detector while installed using the LC-B1-15X
Outdoor Mounting Bracket. The range may vary between 5 and 15m (16ft to 49ft).
8.3 Sensitivity Adjustment
The calibration of detector sensitivity is performed by a single sensitivity potentiometer and
a Microwave intensity jumper. Changing the PIR sensitivity and microwave intensity affects
immunity to environmental noises and allows the detector to operate without nuisance
alarms in noisier environments. The microwave intensity jumper is marked with "H" (high)
and "L" (low) settings. The sensitivity potentiometer is marked with "-" to "+". Position "-" is
the minimum sensitivity and position "+" is the maximum sensitivity. The PIR sensitivity and
microwave intensity must be adjusted according to environmental conditions as follows:
