Batteries: If the Base Station batteries are low, the Base
Station will beep every 30 minutes. The AA batteries
in the Motion Sensor will last up to 2 years depending
on use (Lithium batteries are recommended for colder
environments). If the Motion Sensor batteries are low, the
Base Station will beep every 30 minutes until the batteries
are replaced. The Motion Sensor will continue to operate
with a low battery, however the light will not illuminate. For
peak performance, inspect batteries annually and replace as
needed.
Programming Additional Motion Sensors: The Base Station
can learn the code of up to 7 additional Motion Sensors,
responding with unique buzzes. To program additional
Motion Sensors see Step 4.
To order additional Motion Sensors call 1-800-528-9131.
Clear Memory: Press and hold the Learn Button on the Base
Station until 3 beeps are heard.
On/Off: To turn the Base Station on and off, hold down the
power button until you hear the on/off tone.
Volume: The Base Station is equipped with adjustable
volume controls. The lowest volume setting is the mute
feature.

Operation and Features
Overview
The Wireless Motion Detection System uses a Passive Infra-Red (PIR) Motion Sensor to detect movement of people and vehicles.
The Base Station is powered by the DC adapter and the 4 AA batteries supply power in case of a power outage.
NOTE: The Base Station is intended for indoor use only.

mounting plate with large silver
screw. Tighten screw until
Motion Sensor stays in place
when repositioned.
Install 4 AA Alkaline
batteries. (Lithium batteries
recommended for colder
environments.)
LED light will flash.
Plug in the Base Station.
Adhere rubber pads to the
bottom of the base.
4 AA batteries are optional in
case of a power failure. OPTIONAL

MOTION SENSOR INSTALLATION
Mount Motion Sensor
horizontally on solid surface
3-5 feet (1-1.5 m) off the
ground and within 1/2 mile
(0.8 km) of Base Station (rotate
sensor to access screw holes).
Unit should be able to swivel as
needed.
Attach sun/rain shield.
NOTE: Keep Motion Sensor
antenna away from metal
objects. Do not mount Motion
Sensor in direct sunlight, near
moving tree branches, or in the
path of a sprinkler system.
4 feet (1.2 m)
10-20 feet (3-6 m)
Vehicle Alert Installation: For cars, the best mounting
position is about 4 feet (1.2 m) high, between 10-20 feet
(3-6 m) back, and angled to see the back of car after passing
the sensor.

Test Motion Sensor by waving
hand in front of sensor. LED
light should flash and the Base
Station will buzz X number of
times indicating which sensor
has been activated.

Troubleshooting
The Motion Sensor lights up, but the Base Station does not
respond.
The Motion Sensor must be programmed to Base Station (See
Step 4). Ensure Base Station is on and the volume is turned up.
Motion Sensor is detecting motion only part of the time.
Ensure the Motion Sensor is set to the High Sensitivity setting
(See Step 2). To detect cars, it is best to mount Motion Sensor
at height of car’s motor and have it between 10-20 feet (3-6 m)
from the road. Swivel sensor as needed.
The Wireless Motion Detection System is giving false alarms.
Check for moving tree branches or insects in sensor window.
Motion Sensor can also be triggered by light shining directly in
sensor window, such as reflected sunlight, or motion in front of
a light source.
It is possible that condensation has built up on the sensor. Wipe
condensation from Motion Sensor with cotton swab. Let it sit
inside for a few hours, open to the air, without the batteries and
it should correct itself.
Check Sensor Switches on Motion Sensor. See Switch Settings.
Base Station beeps every 30 minutes.
The batteries in the Base Station or the Motion Sensor(s) are
low. Replace the 4 AA batteries. Check the Motion Sensor(s),
if the LED illuminates on all of the Motion Sensors, change the
batteries in the Base Station.
The Wireless Motion Detection System is not getting
expected transmission range.
Keep both antennas vertical and keep Motion Sensor antenna
away from trees and metal objects. Ensure Base Station is in
clearest possible sight of the Motion Sensor. The less objects
between the devices, the longer the range.
NOTE: The manufacturer is not responsible for any radio or
TV interference caused by unauthorized modifications to this
equipment. Changes or modifications not expressly approved
