Overview

The Wireless Motion Alert uses a Passive Infra-Red 
(PIR) 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.

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 batteries are low, 
the base station will beep every 30 minutes until the 
batteries are replaced. The PIR 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 3 additional 
PIR Motion Sensors, responding with unique buzzes. 
To program additional PIR Motion Sensors see
