Why won't my Inficon Security Sensors detect CO2?

  Michael CruzAug 14, 2025
  If your Inficon Security Sensors unit isn't detecting CO2, several factors could be at play. First, ensure the unit has completed its warm-up phase, indicated by a beeping sound and the absence of flashing yellow lights (a single green light flashing is acceptable). If yellow lights are scrolling, allow 90 seconds for warm-up. If the issue persists, contact INFICON. The pump's functionality is also crucial; listen for it near your ear after warm-up, verifying it's not a low battery issue. A clogged filter cartridge can impede airflow to the IR cell, so replace it with a new one. Finally, a dead battery can prevent detection, so please refer to section #3.

What to do if the green, last yellow, and amber charging LEDs flash on my Inficon Security Sensors?

  If the green, last yellow, and amber charging LEDs on your Inficon Security Sensors are flashing after the warm-up sequence, it typically indicates that the battery requires recharging. Allow the battery to charge for 10-12 hours. If the problem persists, the power stick may have failed and require replacement with part #712-700-G1.

How to fix all yellow lights flashing together on Inficon Security Sensors?

  Jeffrey ChavezAug 21, 2025
  If all the yellow lights on your Inficon Security Sensors are flashing together, it could be due to the IR sensor cell becoming unseated or failing. First, remove the sensor access door and gently push both ends of the sensor down, being careful not to remove or reinsert the sensor cell. Then, restart the unit and observe. If the issue remains, the IR sensor cell may have failed and require replacement.

What to do if Inficon Security Sensors unit doesn't power up and Hi/Lo indicators flash?
- B
  Brandon DavisAug 25, 2025
  If your Inficon Security Sensors unit does not power up and the Hi/Lo indicators flash rapidly in an alternating manner when the AC adapter is connected, it suggests that the power stick/battery has been connected in reverse. To resolve this, access the power stick, disconnect it, and reconnect it, ensuring you pay attention to the key connector.

Why is my Inficon D-TEK CO2 Security Sensors very erratic?
- R
  Ryan BryantAug 29, 2025
  If your Inficon Security Sensors unit is very erratic and goes off when bumped slightly, it may be due to high or rapidly changing CO2 levels in the background. Try to reduce the CO2 concentration or limit changes in the background environment. For example, the operator could wear a mask.

What causes the pump to stop working on Inficon Security Sensors?
- A
  abigailhillSep 1, 2025
  If the pump on your Inficon Security Sensors is not working, it may have failed. To verify, listen for the pump running near your ear after the D-TEK CO2 has completed its warm-up sequence. Also, confirm that it is not a low battery condition. If the pump is still not running, contact INFICON.

Why my Inficon Security Sensors will not detect CO2?
- S
  samantha66Sep 5, 2025
  If your Inficon Security Sensors unit will not detect CO2, it could be due to several reasons. First, ensure the unit has warmed up completely, indicated by a beep and the absence of flashing yellow leak indicators (a single green light flashing is acceptable during warm-up). If yellow lights are scrolling, wait 90 seconds. Second, verify the battery is charged and properly connected, and listen for the pump. If it's still not running, contact INFICON. Third, a clogged filter cartridge can prevent proper airflow, so try installing a new one. Lastly, the battery itself might have failed, consider replacing it.

  Holly RogersSep 9, 2025
  If the pump isn't working on your Inficon Security Sensors, ensure the battery is adequately charged and properly connected. If the pump still doesn't run after the unit has warmed up, it might indicate a pump failure, in which case contact INFICON.
