Overview
The Wireless Alert Sensor is a Passive Infra-Red
(PIR) sensor that detects movement of people and
vehicles, while allowing small animals to pass through
undetected. Each sensor has its own unique ID, for a
secure radio link. The base station (not provided) can
learn the signals of up to 4 sensors. The base station
gives a single beep for the first sensor that is
programmed, a double beep for the second, and so
on. Additionally, multiple base stations can work with
the same sensor to sound in different places.
PIR Motion Sensor
Assembly & Test
Step 1
Attach PIR Motion Sensor box to mounting plate with
large silver screw. Tighten screw until PIR Motion
Sensor stays in place when repositioned.

Step 5
Programming PIR Motion
Sensor to Base Station
Test PIR Motion Sensor by waving hand in front of
sensor. Test light should flash. Secure cover with the
smallest screws.
Insert battery pack facing away from circuit board and
attach cover.
NOTE: Ensure the batteries do not touch the circuit
board and the antenna and battery wires are not
pinched.
Step 4
B Within 5 seconds, wave hand in front of PIR Motion
Sensor. Test light will illuminate and Base Station
will buzz.
A Ensure Base
Station and PIR
Motion Sensor are
in close proximity
to each other.
Press and release
learn button on
Base Station.
Buzzer will sound.
Step 6
PIR Motion Sensor Installation
Mount PIR Motion Sensor
horizontally on solid surface a few
feet off the ground and within 900'
of Base Station (rotate sensor to
access screw holes). Unit should be able to swivel as
needed. Attach sun/rain shield.
NOTE: Keep PIR Motion Sensor antenna away from
metal objects. Do not mount PIR Motion Sensor in
direct sunlight, near moving tree branches, or in the
path of a sprinkler system.

Troubleshooting
The PIR Motion Sensor lights up, but the Base
Station does not respond.
The PIR Motion Sensor must be programmed to Base
Station (See Step 5).
Ensure Base Station is on and is not muted.
If the green power light is not lit or is flashing, press
the Mute Button on the top of the Base Station to
wake it up.
If the green power is illuminated, look at the two small
white Base Station switches next to the Learn Button.
The #1 Dip Switch should be down, towards the
circuit board. If it is up, the Base Station has been
muted. If the Base Station signals when you press the
Learn Button, it is not muted.
PIR Motion Sensor is detecting motion only part
of the time.
To detect cars, it is best to mount PIR Motion Sensor
at height of car’s motor and have it between ten and
twenty feet from the road. Swivel sensor as needed.
The Alert is giving false alarms.
Check for moving tree branches or insects in sensor
window. PIR 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 PIR 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 PIR Motion Sensor. See
Switch Settings.

Base Station beeps every ten minutes.
The batteries in the Base Station are low. Replace
with 4 AA batteries or operate it using AC Adapter.
The Alert is not getting expected transmission
range.
Keep both antennas vertical and keep PIR Motion
Sensor antenna away from trees and metal objects.
Ensure Base Station is in clearest possible sight of
the PIR 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 by the
manufacturer could void the user’s authority to
operate the equipment.
3' - 5'
10' - 20'
Vehicle Alert Installation: For cars, the best
mounting position is about 4' high, between 10-20'
back, and angled to see the back of car after passing
the sensor.
