    What to do if Det-Tronics LS2000 Security Sensors show a calibration fault?
    • C
      Cassidy WilsonAug 3, 2025
      A calibration fault in Det-Tronics Security Sensors occurs if the calibration process times out. To resolve this, perform a successful calibration to reset the fault.

      Eric SloanAug 9, 2025
      If your Det-Tronics Security Sensors are showing a low 24 volts error, it means that the 24 VDC operating voltage is out of the acceptable range. Ensure the wiring to the detector is correct and that the power source is outputting the correct voltage. After correcting the issue, the power supply faults should clear automatically. If the problem continues, it is recommended to consult the factory.

    What to do if Det-Tronics Security Sensors have negative signal output?
    • K
      Kristen WilliamsAug 15, 2025
      A negative signal output on your Det-Tronics Security Sensors likely means the device was zero calibrated with background gas present. If this occurs, purge the system with clean air and repeat the zero calibration. Also, make sure the heaters are on and the windows are clear of fog.
