What to do if Contrinex SAFETINEX Security Sensors OSSD1 and OSSD2 LEDs remain on in red?
- P
  Pamela WelchAug 3, 2025
  If the OSSD1 and OSSD2 LEDs on your Contrinex Security Sensors are constantly red, it indicates that the protective field is obstructed, the alignment is poor, or a fault has been detected. First, remove any objects blocking the protective field. If the problem persists, realign the sender and receiver units. As a last resort, try power cycling both units by switching the power supply off and on again.

  Rhonda AdkinsAug 9, 2025
  If the OSSD1 and OSSD2 LEDs are red while the sender's LEDs are off (excluding the power LED) on your Contrinex Security Sensors, it could be due to an OSSD short-circuit or a device malfunction. Ensure that the OSSDs are not shorted together or connected to 0V or 24VDC. If the issue continues, the unit may need to be returned for revision.

Why Contrinex SAFETINEX Security Sensors power LED (receiver) does not light up?
- J
  Joe SimpsonAug 15, 2025
  If the power LED on the receiver of your Contrinex Security Sensors isn't lighting up, it means there's either no operating voltage or the voltage is too low. Check the voltage supply to resolve this issue.
