That is an SMKT3. Are you saying you have two different SMKT3s? Or is that the same sensor you were just referring to originally?
Note there is only one SMKT3 programmed into your panel currently based on what the panel is reporting to ADC. If you have more than one sensor, you’ll want to verify which is connected. This is pretty easy to do by tampering the sensor.
The other can be learned in by following these instructions.
