Batteries: If the AC 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 
needed.

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

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 AC adapter and the 4 AA batteries supply power in case 
of a power outage.
NOTE: The Base Station is intended for indoor use only.
