(Note: This article is for the SMKT8 smoke detector if this is not your smoke detector or you are unsure what smoke detector you have click here.)

The Smoke Detector has a built-in tamper switch to deter unauthorized interference. When the Alarm Panel reports a tamper trouble condition, it usually means the mounting plate and the sensor are loose or not properly seated. This occurs most frequently after changing sensor batteries.

Troubleshooting Sensor Tampering 

• Make sure the sensor is securely connected to the mounting plate. (It is recommended to remove and re-attach the sensor to the plate to ensure proper connection as displayed in the image above). 
• Make sure the alignment markers on the Mounting Plate and the Detector are perfectly aligned

If your sensor continues to report tampering and you have ensured proper sensor alignment, please reach out to our support for further assistance.
