Problem: My motion sensor isn’t detecting movement.
Solution: 
•  The motion sensor may not be within range of the Indoor Alarm Receiver. Sometimes 

obstructions between the sensor and receiver such as walls, metal objects, etc in the 

environment can affect the sensor’s functional range. 

•  The battery in the motion sensor is weak. It is recommended to replace the battery 

every 6 months to maintain optimum performance.

Problem: The sensor LED indicator on the Indoor Alarm Receiver is blinking but I don’t 

hear any alarm when my motion sensor is triggered.
Solution: 
•  The alarm for the corresponding sensor has been muted on the receiver. See 

 for instructions on how to 

turn it back on.

Problem: I keep getting false alarms!
Solution: 
•  The sensors use passive infrared to detect changes in temperature so check that there 

are no shifting heat sources in view of the motion sensor(s). This includes the obvious 

things, such as moving pets or people, but also things such as a moving shadow on 

a hot day (such as the shadow of a tree blowing in the wind). Sometimes reflected 

infrared heat from the sun is enough to trigger the sensor.

•  If you’ve had the Driveway Alert system installed for some time, then the batteries in 

the sensors might be running low, causing erratic behavior.

•  If you’re using the Driveway Alert system in an environment with a high level of 

radio ‘noise’ (that is, somewhere with multiple wireless devices in use) then these 

interfering signals might be interpreted as the system as alarm signals. This should, 

however, be a very rare occurrence.

Problem: The chime doesn’t sound.
Solution: 
•  Check the doorbell battery - the chime indicator should light up when the chime button 

is pressed. Replace if necessary.

•  The chime has been muted on the receiver. See 

 for instructions on how to turn it back on.
