Troubleshooting and Frequently Asked Questions 

 

Nothing Happens. The units Do Not Function 

Check batteries in PIRV. Moving in front of it should cause the window to dimly blink. Make sure you have followed 
the steps to TEACH the units to each other. Make sure the base unit has the power LED illuminated (or Blinking if 
battery powered). 

 

The system is not getting the expected transmission range 

To assure best range; keep the antenna VERTICAL.  Keep the PIRV Unit at least a foot away from trees and metal 
objects.  It can also help to locate the Base unit near a window with the clearest possible sight of the PIRV Unit.  

 

I cannot hear the Base Unit when it signals 

The VOLUME button can be used to increase the volume of speaker, though the motion alert buzzer is not made to 
be  overly  loud.  If  you  need  to  have  a  louder  alarm,  the  receiver has a relay that can activate other electrical 
devices, such as bells, buzzers, or lights.  The relay is a switch that has no power of its own, but can handle up to 
120 volts at 10 amps. 

 

The PIRV Unit is picking up people, but not cars

 

The PIRV sensor is not seeing the car’s hot motor or exhaust. To detect cars, it is best to set the transmitter at 
an angle to the road, between ten and twenty feet from the road, and it also helps to have the sensor mounted at 
the height of the car’s motor.  

 

The unit is signaling constantly, when there is nothing there 

Check for tree branches or other objects that might be moving in a breeze or insects in the sensor window. The 
sensor can also be fooled by light shining directly into the window, such as reflected sunlight, or motion in front of 
a light source.  

 

There is a short beep every ten minutes 

The Base unit is indicating that the 

Battery is LOW

If PIRV’s batteries are low, the Base unit will emit three high-

pitch beeps, every ten minutes. If the Base Unit’s batteries are low, it will have two high-pitch beeps.  

 

How do I clear the Base Unit’s memory 

Press and hold the Learn button, on the Base unit, for 15 seconds. It will give a triple-beep when it has cleared its 
memory and you can re-teach PIRV Units to it. If a PIRV Unit signals, while the Learn button is depressed, the 
procedure will have to be repeated.  

 

I hear Static and Feedback through the Base Unit 

The PIRV is probably to close too the Base unit. Once the PIRV is installed in the desired location, it will operate 
normally.
