WIRELESS MOTION ALERT SENSOR
Overview
The Wireless Alert Sensor is a Passive Infra-Red (PIR) Motion 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 8 sensors. The base station gives a single beep for the fi rst 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.

Assembly & Programming
1
Attach PIR Motion Sensor box
to mounting plate with large
silver screw. Tighten screw
until PIR Motion Sensor stays
in place when repositioned.
2
Install 4 AA Alkaline
batteries. (Lithium batteries
recommended for colder
environments.)
LED light will fl ash.

not touch the circuit board and
the antenna and battery wires
are not pinched.

PIR MOTION SENSOR INSTALLATION
6
Mount PIR 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 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 3). Ensure Base Station is on and the volume is
turned up.
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.
10-20 feet (3-6 m)
4 feet (1.2 m)
Base Station beeps every 30 minutes.
The batteries in the Base Station or the PIR Motion Sensor(s)
are low. Replace the 4 AA batteries. Check the PIR Motion
Sensor(s), if the LED illuminates on all of the PIR Motion
Sensors, change the batteries in the Base Station.
PIR Motion Sensor is detecting motion only part of the time.
Ensure the PIR Motion Sensor is set to the High Sensitivity
setting (See Step 2). To detect cars, it is best to mount PIR
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 Alert is giving false alarms.
Check for moving tree branches or insects in sensor window.
PIR Motion Sensor can also be triggered by light shining
directly in sensor window, such as refl ected 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.
NOTICE: To comply with FCC and or Industry Canada rules (IC), adjustment or modifications of this
receiver and/or transmitter are prohibited, except for changing the code setting or replacing the
battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.
Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired operation.
FOR TECHNICAL SUPPORT DIAL OUR TOLL FREE NUMBER:
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 modifi cations to this
equipment. Changes or modifi cations not expressly approved
by the manufacturer could void the user’s authority to operate
the equipment.
