Wireless motion alert.
Hide thumbs
The Wireless Motion Alert uses a Passive Infra-Red (PIR) Motion Sensor to detect movement of people and vehicles, while allowing
small animals to pass through undetected. 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.

Batteries: If the DC adapter is not connected, the
AA batteries in the Base Station should last up to one week.
If the Base Station batteries are low, the Base Station will
beep every 30 minutes. The AA batteries in the PIR Motion
Sensor will last up to 2 years depending on use (lithium
batteries are recommended for colder environments). If
the PIR Motion Sensor batteries are low, the Base Station
will beep every 30 minutes until the batteries are replaced.
The PIR 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
Programming Additional PIR Motion Sensors: The Base
Station can learn the code of up to 7 additional PIR Motion
Sensors, responding with unique buzzes. To program
additional PIR Motion Sensors see Step 4.
To order additional PIR Motion Sensors call
Clear Memory: Press and hold the Learn Button on the Base
Station until 3 beeps are heard.

  • Page 3: Troubleshooting

    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 4). Ensure Base Station is on and the volume is turned up. 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).

    My base unit sometimes chirps are barely audible tone.
    Not the normal beep when activated. What can cause this?

    I received a cwa2000 for a birthday gift and my wife says it works good. however I have some hi frequency hearing loss and can not hear the base unit. is there any way to change the tone to a lower frequency? could you please let me know.

    I've had one like this for 9 years and it works great. It is called The Reporter and I got it at Radio Shack but still looks the same.
    The batteries in the PIR have only been replaced once. It did have a problem recently with condensati​on in the PIR so followed the trouble shooting suggestion of opening it up and letting it dry in the house. My base unit has the option of attaching a wireless door bell to increase the sound to where my 70+ year old ears can easily hear it. It has been a great unit.

    My base unit keeps bleeping and it is plugged into power with no batteries. I have replaced batteries in the sensor and it reset with learn buttons but base unit keeps bleeping every few minutes. Help
