Door/Window Sensor Tampering

Most alarm equipment has a built-in tamper switch to deter unauthorized interference. When the panel reports a tamper trouble condition it usually means the mounting plate and the sensor case are loose or not properly seated. This occurs most frequently after changing sensor batteries.

Troubleshooting Sensor Tampering 

1. Make sure the sensor case is securely fastened.
2. If that doesn't seem to be the issue, remove and re-add the sensor.
